Let x = smaller number
Let y = bigger number
y = 7x + 4
x + y = 92
x + (7x + 4) = 92
8x + 4 = 92
8x = 88
x = 11
y = 7x + 4
y = 81
To find the area of this entire shape, we must divide it into two rectangles.
The first rectangle is on the bottom of the shape, with a length of 8 cm and a width of 3 cm.
The second rectangle is on the top of the shape. The length is (8-5) cm and the height is (7-3) cm.
To find the area of the total shape, we must add the areas of the two rectangles. To find the area of the rectangle, we use the formula, A = l * w.
8 * 3 = 24 cm^2
3 * 4 = 12 cm^2
24 sq cm + 12 sq cm = 36 square centimeters.
Therefore, the area is 36 square centimeters. Hope this helps! :)
Answer:
Step-by-step explanation:
You need at least $90 dollars, so x will be bigger than or equal to that amount.
Your parents don't want to give you more than $150 dollars so x is smaller than or equal to that amount.

Answer:
Initial Value is 2
Base is 3
Exponential curve for its graph
Step-by-step explanation:
The function 
is an exponential curve.
The base of the function is 3.
The initial value is when x=0. Substitute x=0. 
.
This is true since any base to the exponent of 0 is 1.
