Answer: 8.1
Step-by-step explanation:
758.16 ÷ 13 =58.32
58.32 ÷ 7.2 = 8.1
Check: 8.1 ×13 ×7.2=758.16

Answer:
c. (√3 + √5) - i
Step-by-step explanation:
(√3+i) + (√5-2i) = √3+i + √5-2i = (√3 + √5) + (i - 2i) = (√3 + √5) - i
Answer:
y = -3x + 8
Step-by-step explanation:
This looks like it's in slope-intercept form.
So, they want you to write it like y=mx+b, where m is the slope and b is the y-intercept.
First, find the slope.
The slope is calculated by using:
You have several points. Let's use (1,5) and (2,2)
= 2
= 5
= 2
= 1
= = -3
The slope (m) is -3.
y = -3x + b
Now, find the y-intercept.
Substitute points in for y and x.
Let's use (1,5) (x,y)
x= 1
y=5
5= -3(1) +b
5 = -3 + b
b = 8
Add b to your equation.
y = -3x + 8
