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

Answer:
Triangle ADB is congruent to triangle DBC
Step-by-step explanation:
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.

Seven less than 4 times the square of a number is 18. Find the two numbers.
The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
Let the unknown number be "x"
The square of an unknown number is expressed as x²4 times the square of a number is 4x²Seven less than 4 times the square of a number is 4x² - 7If the resulting expression is 18, this will be expressed as 4x² - 7 = 18
Solving the resulting expression
[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]
Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

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

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

If Triangle ABC~trIangle DEC, find the value of x and y."
Answer:
The right answer would be (D) x = 1.
Step-by-step explanation:
So since triangles ABC and DEC are congruent to each other, your gonna try to find the value of x. So from the figure we know that AB = 4x - 1, BC = 4, AC = 5, DE = x+2, CE = 4 and EC = 5. And since ΔABC ≅ ΔDEC the corresponding sides would be equal. And after, we will have :
AB = DE
4x - 1 = x + 2
4x - x =2 + 1
3x = 3
x = 1
So, as it shows, the value of x is one. So (D) x = 1 is the right answer. Hope this helped! :)

Answer:
5
Step-by-step explanation:
Sandy has 15 roses, 5 daises and 10 tulips
She wants to arrange the flower in such a way that each bouquet will have the same flower in it
Therefore the greatest number of flowers that will be in each bouquet is 5 flowers this is so inorder to make each bouquet contain equal number of flowers, this means that one bouquet must not be greater than the other.

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

Stella solves the following system of equations using the substitution method.
y=−4x−65x−y=10
What is the single-variable equation she solves after substituting?
5x−4x−6=10
5x−(−4x−6)=10
5x+10=−4x−6
5x+10=−(4x−6)
Answer:
5x-(-4x-6) = 10
Step-by-step explanation:
Given the expression
y=−4x−6 ..... 1
5x−y=10... 2
To get the required equation we will substitute equation 1 into 2
5x-y = 10
5x-(-4x-6) = 10
5x+4x+6 = 10
9x+6 = 10
9x = 4
x = 4/9the required equation is 5x-(-4x-6) = 10
