find the value of x so that f(x)=7
The answer is:
x = 5
The value of x such that f(x) = 7 is 5.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given a graph of a function f(x).
The graph is a straight line where there is a unique value of y for each value of x.
We have to calculate the value of x when y = 7.
Taking the y coordinate to 7, the x coordinate corresponding to the y coordinate is 5.
Hence the value of x is 5.

Answer:
A) 98.94 sq. meters
B) 42 sq. meters
Step-by-step explanation:
A) So first we calculate the area for the square which is 15*20 = 300. Then we calculate the area of the circle which is pi*r^2 and in this case the radius is 4 which is 1/2 of 8. The area is approx. 201.06. Then we subtract that from 300. 300-201.06 = 98.94. The answer for A) is approx. 98.94

Solve by substitution
Answers
Answer:
(1,4)
Step-by-step explanation:
Answer: x = 1, y = 4
Steps: 3y + 4x = 16, -2x + y = 2
Isolate y for 3y + 4x = 16: y = (16 - 4x ÷ 3)
Substitute y into the other equation (-2x + y = 2): -2x + (16 - 4x ÷ 3) = 2
Simplify: 16 - 10x ÷ 3 = 2
Isolate x for 16 - 10x ÷ 3 = 2: x = 1
Substitute x = 1 into y = (16 - 4x ÷ 3): y = 16 - 4x · 1 ÷ 3
y = 4, x = 1

A scale drawing of an office space uses a scale of 1 in. : 4 yd. The scale drawing has an area of 12 square inches. What is the area of the actual office space?
Answers
Answer: 48 yards
Step-by-step explanation:
From the question, we are informed that a scale drawing of an office space uses a scale of 1 in. : 4 yd.
When the scale drawing has an area of 12 square inches, to get the area of the actual office space, we multiply the given number by 4 since the actual office space is 4× the scale drawing. This will be:
= 12 × 4 yards
= 48 yards
