Answer:
Step-by-step explanation:
You leave a 10% tip on a $30 dinner bill. Find he amount of the tip and add it to
$30. How much is your total bill, including the tip? *
so since you're only doing 10% of 30, you get 3
add 3 to 30 and you get 33
What is the equation of the line that passes through the point (4,−2) and has a slope of −2?
Answer:y=-2x+6
Step-by-step explanation:
You want to find the equation for a line that passes through the point (4,-2) and has a slope of -2.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was -2. So you can right away fill in the equation for a line somewhat to read:
y=-2x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(4,-2). When x of the line is 4, y of the line must be -2.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the -2 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,-2).
So, why not plug in for x the number 4 and for y the number -2? This will allow us to solve for b for the particular line that passes through the point you gave!.
(4,-2). y=mx+b or -2=-2 × 4+b, or solving for b: b=-2-(-2)(4). b=6.
The ordered pair (3,9) is a solution to the system of
equations below because the values make both
equations true.
2x + 3 = y
2x + y = 15
Is (2,7) also a solution to this system of equations?
Yes
No
Explain your thinking.
Answer:
(2,7) is not a solution to the given system of equations.
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
Add 34+(−212) using the number line. Select the location on the number line to plot the sum.
Answer:
Answer is explained below in the explanation section.
Step-by-step explanation:
Solution:
For this question, we need to have a number line, we can not make the number line here. As it will be very long. Instead, I have attached a number line from -11 to +11 for your understanding and explained it below. Please refer to the attachment below for the number line.
Number Line:
A number line is a line which contains all the numbers from negative infinity to positive infinity divided by a single number zero. It has two sides, left hand side and right hand side. A side left to zero contains all the negative numbers and a side right to 0 contains, all the positive numbers.
So,
We are asked to add 34 in (-212), we will get 178 but with the negative sign, and it will lie on the left hand side of the number line.
SO,
34 + (-212) = 34 - 212 = -178
Hence,
Our sum which is 178 will lie on the left hand side of the number line.

Which equation represents g(x) as a transformation of
g(x) = f(x) -5
g(x) = f(x - 5)
g(x) = f(x) + 5
g(x) = f(x + 5)
Answer:
g(x)=f(x)-5
Step-by-step explanation:
the negative inside the parenthesis reduces the x values but we have the y value reduced by 5 here so it goes outside
The equation represents g(x) as a transformation will be g(x) = f(x) - 5. Then the correct option is A.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
From the graph, we can observe that the function g(x) is 5 units below the function f(x).
If the function gets shifted downward by k units then the k is subtracted from the function. Then the function g(x) is given as,
g(x) = f(x) - 5
The equation represents g(x) as a transformation will be g(x) = f(x) - 5. Then the correct option is A.

on selling a fan for rupees 4700 A shopkeeper loses 6% at what price must he sell it to gain 6 percentage
Given:
Selling price of a fan = Rs.4700
Loss percent = 6%
To find:
The price at which he must sell it to gain 6 percentage.
Solution:
Let x be the cost price of the fan.
Loss percent = 6%
Selling price = Cost price - 6% of cost price
[tex]S.P.=x-\dfrac{6}{100}x[/tex]
[tex]S.P.=x-0.06x[/tex]
[tex]S.P.=0.94x[/tex]
Selling price of a fan = Rs.4700
[tex]4700=0.94x[/tex]
[tex]\dfrac{4700}{0.94}=x[/tex]
[tex]5000=x[/tex]
So, the cost price of the fan is Rs.5000.
Now, he need to sell this fan in 6% gain.
Selling price = Cost price + 6% of cost price
[tex]S.P.=5000+\dfrac{6}{100}\times 5000[/tex]
[tex]S.P.=5000+300[/tex]
[tex]S.P.=5300[/tex]
Therefore, he must sell it for Rs.5300 to gain 6 percentage.
The area of
of a rectangle is (14x^4 + 7x^2) cm²
and its breadth is 7x^2 cm. Find its length.
Answer:
2x^1+1
Step-by-step explanation:
Area=L X W
which means that (14x^4+7x^2) needs to be divided by 7x^2
factorise(14x^4+7x^2) which gives 7x(2x^2+1)
divide 7x(2x^2+1) by 7x^2
gives 2x^2 +1
Answer:
The area of a rectangle is (14x^4 + 7x^2) cm²
and its breadth is 7x^2 cm.
it's length is :---
[tex] = \frac{(14{x}^{4} + 7 {x}^{2})}{7 {x}^{2} } \\ = \frac{7 {x}^{2}(2 {x}^{2} + 1) }{7 {x}^{2} } \\ = (2 {x}^{2} + 1) \: c {m}[/tex]
(2x^2+1) cm is the right answer.

On a windy morning, a hot air balloon starts rising and flying away from the top of a hill. The altitude, h, in feet, of the balloon x hours after starting its ascent from the hill, can be modeled by the function:
Part B: There is a positive and negative x intercept for this function. What is the positive x-intercept?
Explain what this x-intercept represents in the given situation.
h(x)=-16x2+64x+80
Here the positive intercept should be considered as the -1 and 5.
Calculation of the positive intercept:Since X-Intercept shows the landing point i.e. bottom of the cliff since all x intercepts contains a y value of 0.
In this case it would be 0 feet.
So,
[tex]h(x)= -16x^2-16x+80x+80[/tex]
h(x)= -x(16x-16) +5(16x+16)
h(x)= (-x+5)(16x+16)
x intercepts = -1 and 5

Answer:
x = 79.799
Step-by-step explanation:
Apply trigonometric ratio formula to find x.
Thus, find the adjacent side of each triangle using 40° and 65° as reference angles respectively.
✔️Adjacent length of the triangle with reference angle 40°:
tan (40) = 110/adj
adj*tan(40) = 110
Adjacent length = 110/tan(40)
Adjacent length = 131.093 (nearest thousandth)
✔️Adjacent length of the triangle with reference angle 65°:
tan (65) = 110/adj
adj*tan(65) = 110
Adjacent length = 110/tan(65)
Adjacent length = 51.294 (nearest thousandth)
