7 months
Leanna has been saving for 7 months to have the balance of $450.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as linear equation in one variable.
Let's suppose the Leanna has been saving the money for 'x' months
It means total months = x
Intial balance = $100
Each month she deposit = $50
After x months she will have = $450 (with initial balance)
We can frame a linear equation in one variable such that:
50x = 450 - 100 (without initial balance)
50x = 350 (divide by 50 on both sides)
x = 7 months
Thus, Leanna has been saving for 7 months to have the balance of $450.

Multiply the vector in the graph by a scale factor of Negative one-half.The resulting condition for the vector is to be determined.
The scale factor is defined as the ratio of modified change in length to the original length.
What is a vector?A vector is defined as phenomenon that has two independent belongings magnitude and direction. The term also denotes the mathematical or geometrical replica of such a quantity. Norms of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight.
Here, The scale factor is -1/2, where a negative sign shows that the vector will get inverted and 1/2 implies that it will be shortened by 1/2.
Thus, when multiplying the vector in the graph by a scale factor of 1/2. The resulting vector will be shorter than and II. Option D is correct.

Item 8 A dog is leashed to the corner of a house. How much running area does the dog have? Round your answer to the nearest square foot, if necessary. The dog has about square feet of running area.
Complete Question:
A dog is leashed to the corner of a house with a 15 foot leash. How much running area does the dog have? Round your answer to the nearest square foot.
Answer:
The dog has about 707 square feet of running area.
Step-by-step explanation:
From the illustration in the question, one can conclude that the dog can travel in a circular path.
So, the length of the leash represents the radius and we are to calculate the required area using the area of a circle.
We have:
[tex]Radius = 15ft[/tex]
[tex]Area = \pi r^2[/tex]
Where
[tex]r = Radius = 15[/tex] and [tex]\pi = 3.14[/tex]
So:
[tex]Area = 3.14 * 15^2[/tex]
[tex]Area = 3.14 * 225[/tex]
[tex]Area = 706.5ft^2[/tex]
[tex]Area = 707\ ft^2[/tex]

Solve for y y + 7 = 9
Answer:
y = 2
Step-by-step explanation:
Given
y + 7 = 9 ( subtract 7 from both sides )
y = 2
Simplifying
y + 7 = 9
Reorder the terms:
7 + y = 9
Solving
7 + y = 9
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + y = 9 + -7
Combine like terms: 7 + -7 = 0
0 + y = 9 + -7
y = 9 + -7
Combine like terms: 9 + -7 = 2
y = 2
Simplifying
y = 2

Which set of equivalent measures does not indicate that two triangles must be congruent?
A anglo-angle-angle B. side-angle-side
C. angle-side-angle D. angle-angle-side
Answer:
C. angle-side-angle
D. angle-angle-side
Step-by-step explanation:
A triangle is bounded by three sides, thus it has three angle. When two triangles are compared, the length of sides and angles could be similar or not. Thus, the triangle may be congruent or not congruent.
The relationship between congruent triangles can be expressed as regards to their sides, angles, or both.
From the given question, when the three angles of two given triangles are the same, then the two triangles are congruent. This relationship can be expressed as Angle-Angle-Angle.
Also, when two triangles have two equal sides and an included angle to be equal (i.e Side-Angle-Side), then they are congruent.

Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+8=10
Step 1: Subtract 8 from both sides.

−2x=2
Step 2: Divide both sides by -2.
−2x−2=2−2
x=−1
Answer:
Answer:
-2
Step-by-step explanation:
The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.

Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20
The number 0.000000675 can be written in scientific notation as 6.75 x 10x.What is the value of x?
Answer:
x= -7
Step-by-step explanation:
hope this helps you!
The value of x in the expressed scientific notation is;
x = -7
We are given the number 0.000000675.
Now, when writing decimals like this, it means a number has been divided by an exponent of 10.
For example; 0.01 is 1/100.
This means we start counting from the the decimal point of the whole number we want to use to the left. The number of counts we make till the end will be the exponent of 10.
Now, in our question, counting to the left from between 6 and 7 gives us 7.
Thus; we have;
6.75/10⁷
But in our question, multiplication is used and not division.
Thus, we have;
6.75 × 1/10⁷
⇒ 6.75 × 10⁻⁷
Comparing with the question gives;
x = -7

The number of swimmers at a city pool on Monday was twice the number who were there on Tuesday. The number at the pool on Wednesday was 11 fewer than 3 times the number on Tuesday. The total swimmers for all 3 days were 625. How many swimmers were at the pool each day? Define a variable, write an equation, and solve the problem.
Answer:
102 1/3 swimmers
Step-by-step explanation:
Let
Number of swimmers on Tuesday = x
Number of swimmers on Monday = 2x
Number of swimmers on Wednesday = 3x - 11
Total swimmers for all 3 days = 625
x + 2x + (3x - 11) = 625
3x + 3x - 11 = 625
6x = 625 - 11
6x = 614
x = 614 / 6
= 102 2/6
x = 102 1/3 swimmers
Number of swimmers on Tuesday = x = 102 1/3 swimmers
Number of swimmers on Monday = 2x
= 2(102 1/3)
= 204 2/3
Number of swimmers on Wednesday = 3x - 11
=3(102 1/3) - 11
= 307 - 11
= 296

Answer:
3j + 3m + 21
Step-by-step explanation:
Normally, they would each travel 3 miles, so the total would normally be 3j + 3m. However, for today, Jared ran another 21 miles, so 21 miles is added to the total.
Total distance = 3j + 3m + 21
Answer:
(3j) + (3m + 21)
Step-by-step explanation:
Since every time Jared goes running he runs 3 miles we should multiply j by 3. So we will have: 3j
Since every time Malia goes running she runs 3 miles we should multiply m by 3. So we will have 3m
But this month Jared ran an extra 21 miles so we will have to add that after we have multiplied both j and m by 3.
Since we want the total distance they ran that month, we need to add all of these distances.
This will give us 3j + 3m + 21.
In the answer options 3j is inside a parenthesis as well as 3m + 21. Since inside the parenthesis we only have addition and the order which we add doesn't really make a difference, the parenthesis were unnecessary but they won't affect the answer.

Write an equation that represents the transformations formed by the following items:
(a) horizontally shifting the graph 4 units to the left of f(x) = √x and then vertically compression by a factor of 1/3
(b) vertically stretching the graph by a factor of 4 of f(x) = √x and then vertically shifting the graph 3 units up
(c) horizontally stretching the graph of f(x) = √x by a factor of 2 and then vertically shifting the graph 6 units down
Answer:
a) [tex]f(x) = \frac{1}{3} \sqrt{x+4}[/tex]
b) [tex]f(x)=4\sqrt{x} + 3[/tex]
c) [tex]f(x) = 2\sqrt{x} -6[/tex]
Step-by-step explanation:
a) The function will be;
⇒ f (x) = 1/3 √(x + 4)
b) The function will be;
⇒ f (x) = 4√x + 3
c) The function will be;
⇒ f (x) = 2√x - 6
What is Translation?
A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
There are some transformations are given.
Now,
For (a);
The function is horizontally shifting the graph 4 units to the left of
f(x) = √x.
So, The function become;
f (x) = √(x + 4)
And, Then vertically compression by a factor of 1/3.
So, The function become;
f (x) = 1/3 √(x + 4)
For b:
The function is vertically stretching the graph by a factor of 4 of f(x) = √x.
So, The function become;
f (x) = √x + 3
And, Then vertically shifting the graph 3 units up.
So, The function will be;
⇒ f (x) = 4√x + 3
For c;
The function is horizontally stretching the graph of f(x) = √x by a factor of 2.
So, The function become;
f (x) = 2√x
And, Then vertically shifting the graph 6 units down.
So, The function will be;
⇒ f (x) = 2√x - 6
Thus,
a) The function will be;
⇒ f (x) = 1/3 √(x + 4)
b) The function will be;
⇒ f (x) = 4√x + 3
c) The function will be;
⇒ f (x) = 2√x - 6

b) 65.9%
Step-by-step explanation:
a) You can use n=1 to find the percentage remaining at the end of 1 hour:
P = 100(0.87^1) = 87
This is 13% less than 100%, so the decay rate per hour is 13%.
