Answer:
y = 8x + 2
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y-intercept value
Answer: 6
Step-by-step explanation:
0, 3, 4 , 6, 6, 7, 7, 9
6+6= 12
12 ➗ 2 = 6
Answer:
216 US dollars
Step-by-step explanation:
Let the amount he earned for babysitting be x
He spent 1/4 of x on guitar=(1/4)×x=1/4x
He gave 1/4 of x to charity= (1/4)×x=1/4x
Equation 1
Total amount left=(Total amount earned -Total amount spent)
Total amount earned=x
Total amount spent=(Spent on Guitar+Spent on Charity)=(1/4x)+(1/4x)=1/2x=0.5x
Total amount left=108 US dollars
Substituting in equation 1
108=(x-0,5x)
Solving
0.5x/0.5=108/0.5
x=216 US dollars
He started with 216 US dollars
(2,-1)
(x-y)
4(2) + 3(-1) = 5
4×2=8
3×-1= -3
8+(-3)=5
i hope that helps i dont know how to explain it any better
I've never seen the notation DO 2(x,y) but let's assume it means a dilation of a scale factor of 2 around the origin.
Then it's true that DO,2(x,y)=(2x,2y)
We're not given any information about QRS so we don't know the slope of its sides; dilation by two won't change those slopes.
The vertices will be twice as far from the origin on the image than on the preimage, that's what dilating by two means.
The distance OQ' = 2 OQ; that's what this dilation does.
