To find f(1), substitute 1 for x.
f(1) = (3(1)+7)²
f(1) = (3+7)²
f(1) = 10²
f(1) = 100
Answer:
E
Step-by-step explanation:
The first thing you should do for this case is to find the equation of the line that best suits the problem and then plot it.
Let
x: number of months
y: amount paid.
The equation of the line is
y = 15x + 25
y-intercept = 25
the slope = 15
answer Georgie pays (y axis) $ 15 dollars (the spole) monthly (x-axis) in the gym with a $ 25 registration (y-intercept)
Answer:
Step-by-step explanation:
Let's solve for b.
−2(bx−5)=16
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2x.
−2bx/−2x=6/−2x
b=−3x
Answer:
b=−3x
———————————————————
Let's solve for x.
−2(bx−5)=16
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2b.
−2bx/−2b=6/−2b
x=−3b
Answer:
x=−3b

Hey there! :)
You have to find the area of all of them and add it together.
Formulas:
Area of a square: l · w
Area of a triangle: (b · h) ÷ 2
Square -
l = 3
w = 3
3 × 3 = 9
Triangle -
b = 3
h = 3
(3 × 3) ÷ 2
9 ÷ 2 = 4.5
There are 4 triangles
4.5 × 4 = 18
9 + 18 = 27
The surface area ⇒ 27 cm²
