y= 10x+ 43
Step-by-step explanation:
step 1. y= 5(x+4)2+3
y= 10(x+4)
Answer:
Your answer is B or option 2.
Step-by-step explanation:
When doing scale factors, you will multiply. Always. To get from the original box to the second box, you will multiply by a scale factor of 5/8. An equation can model this. b=5/8a. (Let a = dimensions of original/blue box, let b = dimensions of second/green box).
Since you need to find the dimensions of the first/original box, you need to change b=5/8a to a= <em>[something]. </em>To do that, divide both sides by 5/8. You have b / 5/8 = a. The dimensions of the second box divided by the scale factor 5/8 is the dimensions of the first box. This also makes sense, because the green box looks smaller than the blue box. Hope I helped! This is a challenging subject to explain properly. ^_^"

Answer:
9. Always true
10. Always true
11. Never true
12. Always true
13. Always true
14. Never true
Step-by-step explanation:
An inverse is defined as the reflection across the line y=x. Algebraically this means that x and y switch place in the inverse equation and in the coordinate points of a function.
A line will always give a line.
Example: y = 2x -2
Inverse: x = 2y -2 which when rearranged is y = 1/2 x +1.
This also means that the slope if greater than 1 for the function will have a slope less than 1 for its inverse.

Let 'x' denote the length of the base and let 'y' denote the length of the legs.
We know that isosceles triangles have one base and two legs that are the same length. So, the perimeter is:
x+y+y
= x+2y = 50
The problem tells us that the base is half as long as a leg, so that means:
y=2x
We can use the method of substitution here. Let's substitute the 2nd given equation into the first one. The work follows:
x+2y=50
x+2(2x)=50
x+4x=50
5x=50
x=50/5
x=10
To work out what the length of our legs are, we can use our found 'x' value to solve either of our previously established equations. Let's use the second one:
y=2x
y=2(10)
y=20
Just to confirm our answer is correct, let's verify it with our first equation.
x+y+y=50
10+20+20=50
50=50
Our answer is consistent, so the base has length 10, and each leg has length 20.
