Answer:
if 70ft and 56ft the height is 56 x 2 =112ft
Step-by-step explanation:
Answer: A
Sustitute one of the inputs into all of the equations and see if you get the respective output. I will use the point (0,2).
A. f(0)=8(0)+2
f(0)=2
Option A works!
B. f(0)=8(0)-2
f(0)=-2
Option B doesn’t work.
C. f(0)=8(0)
f(0)=0
Option C doesn’t work.
Since option A is the only one that works, the correct function is A.

Answer:
Long part= 45
Short part= 25
Step-by-step explanation:
Let the short part of the stick be x
Let the long part be x+20
The total length of the stick is 70cm
x + (x+20)= 70
x+x+20= 70
2x+20= 70
2x= 70-20
2x= 50
x= 50/2
= 25
Longer part length= 20+25
= 45
The short part is 25
Answer:
Shorts: 38
T-Shirts: 152
Step-by-Step
The number of shorts sold can be written as (s) and the number of t-shirts sold can be written as (t)
We know that shirts are $2, and shorts are $4, and the total sales were $456, so the following equation can help us to find the answer, since if we add up the money from shirts and the money from shorts we’ll get the total sales.
4s + 2t = 456
Next, we know that shirts were bought 4 <em>times </em> <em>more </em>than shorts, so we can also write the following equation:
4s = t
Now, since we have a defined “value” for t
(<em>t = 4s), </em>we can substitute this value into the first equation.
4s+ 2(4s) = 456,
4s + 8s = 456,
12s = 456
s = 38
Now we can use this value in the second equation, and solve for t
4s = t
4(38) = t
152 = t
