Pythagorean Theory, a^2 + b^2 = c^2
24^2 + 7^2 = x^2
527 = x^2
x = 22.96
To solve this problem, we must substitute the value of -1 in for x in the function. This means that for every x there is in the equation, we must substitute the value -1 in for it in order to find the value of g(-1). This is modeled below:
g(x) = -5x + 13
g(-1) = -5(-1) + 13
Next, we must simplify using the order of operations. PEMDAS outlines this concept, telling us to simplify parentheses first, exponents next, then multiplication and division, and finally addition and subtraction. In this case, we will solve the multiplication and then the addition, as modeled below:
g(-1) = -5(-1) + 13
g(-1) = 5 + 13
g(-1) = 18
Therefore, your answer is 18.
Hope this helps!
Answer:
a=2
b=40m
c=2m/s
Step-by-step explanation:
slope is rise over run so 10/5 simplified is 2/1 or 2
for b just look at the graph at the 20th second
for c you do distance over time so basically the same thing as a 10/5 which is 2m/s
1. The formula for calculate the perimeter of a rectangle, is:
P=2L+2W
P is the perimeter of the rectangle (P=320 feet).
L is the lenght of the rectangle.
W is the width of the rectangle.

2. The problem says that the length of the rectangle is three times the width, so you have:
</span>
L=3W
3. When you substitute L=3W and P=320, into P=2L+2W, you obtain:
P=2L+2W
320=2(3W)+2W
320=6W+2W
8W=320
W=320/8
W=40 feet
4. The barn forms one end of the rectangle. Therefore the linear feet of fence (x) is:
x=P-W
x=320 feet-40 feet
x=280 feet
<span>
How many linear feet of fence must he buy?
</span>
The answer is: 280 feet
4 would go on the x axis because it always starts like this (x, y)
