Answer:
a= 13+3b
Step-by-step explanation:
Simplifying
a + -7 = 3(b + 2)
Reorder the terms:
-7 + a = 3(b + 2)
Reorder the terms:
-7 + a = 3(2 + b)
-7 + a = (2 * 3 + b * 3)
-7 + a = (6 + 3b)
Solving
-7 + a = 6 + 3b
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + a = 6 + 7 + 3b
Combine like terms: -7 + 7 = 0
0 + a = 6 + 7 + 3b
a = 6 + 7 + 3b
Combine like terms: 6 + 7 = 13
a = 13 + 3b
Simplifying
a = 13 + 3b

Omar has a gift card with a $150 balance he buys several video games that cost $35 each after the purchase has his gift card balance is $45
Answers
Answer:
3
Step-by-step explanation:
150-35=115
115-35=80
80-35=45
Answer:
Omar bought 3 games? (You didn't ask a question but this is what I assumed)
Step-by-step explanation:
Use this equation to find out how many games (x) Omar bought with $45 left over.
45 = 150 - 35x
Combine like terms and put them on opposite sides of the equal sign.
-105 = -35x
Divide both side by -35
3 = x, so x = 3

Which equation can be used to find the surface area of the cylinder?
r= 6 cm
h = 8 cm
S= 28(8)2 +2 (12)(6)
O S=2(6)? +2(6)(8) *
O S=212)2 + 23412)(8)
S = 2846)2 +27(6)(8)
Answers
Answer:
S = 2π(36) + 2π(6)(8)
S = 2(3.14)(36) + 2(3.14)(6)(8)
Step-by-step explanation:
The surface area of a cylinder is the sum of the area of the base and the lateral area. A cylinder has 2 circular base .
Surface area = 2πr² + 2πrh
surface area = 2πr(r + h)
where
r = radius
h = height
surface area = 2πr(r + h)
r = 6 cm
h = 8 cm
The equation to find the surface area is represented below.
Surface area = 2πr² + 2πrh
S = 2π (6²) + 2π (6)(8)
S = 2π(36) + 2π (6)(8)
Assuming π is given as 3.14 the equation will be as follows
S = 2(3.14)(36) + 2(3.14)(6)(8)

What are the coordinates of the vertex of the function f(x) = x2 − 12x + 5?
(6, 31)
(−6, 31)
(6, −31)
(−6, −31)
Answers
Answer:
This means that the coordinates of the vertex of the function are [tex](6,-31)[/tex]
Step-by-step explanation:
To find the x-coordinate of the vertex of a quadratic function, we can use the formula:
[tex]x=\frac{-b}{2a}[/tex]
We are given the function [tex]f(x)=x^2-12x+5[/tex]
In this function, [tex]a=1[/tex] and [tex]b=-12[/tex]
Now we can input these values into our formula
[tex]x=\frac{-(-12)}{2(1)} \\\\x=\frac{12}{2} \\\\x=6[/tex]
This means that the x-value of the vertex is located at [tex]x=6[/tex]. To find the other half of the coordinate pair, we can now plug [tex]x=6[/tex] into the given function
[tex]f(6)=(6)^2-12(6)+5\\\\f(6)=36-72+5\\\\f(6)=41-72\\\\f(6)=-31[/tex]
This means that the coordinates of the vertex of the function are [tex](6,-31)[/tex]
