Answer:
d
Step-by-step explanation:
Given
- 
x - 9 = - 27 ( add 9 to both sides )
- x = - 18 ( multiply both sides by 2 to clear the fraction )
- 3x = - 36 ( divide both sides by - 3 )
x = 12 → d

Answer:
Step-by-step explanation:
Q1
a. y=4.9x -38
b. r=0.936
Q2
strong positive
Q3
Answer c.
Q4
d.y=4.9x -38, for x=20, y=60$
ey=4.9x -38, for y=147,00, x=(147,000-38)/4.9=29,992ft
Answer:
7.2 units
Step-by-step explanation:
Distance² = (Change in y)² + (Change in x)²
Distance² = (4 - -5)² + (-3 - -7)²
Distance² = 36 + 16
Distance² = 52
Distance = 7.211102551
Rounding off the answer to nearest tenth gives 7.2 units
Ok, so for this problem you want to get Y all by itself.
First you’ll want to move your X variables to one side. You do that by adding 2X to both sides of the equation. This will cancel out the -2X and it will turn the 16X into an 18X.
You’re equation is now,
18X+9=9Y
Next you’ll want to divide both sides by 9 so that you’ll get Y all by itself.
Your equation should look like this.
Y=2X+1!
And that’s your answer:) I hope this helped!
