Answer:
7. y=x-2, 8. y=3/2x+4, 9. y=-3/4x+8, 10. y=2x-7, 11. y=-5x-3, 12. y=4x-5, 13. y=-3x-1, 14. y=-1/2x+1, 15. y=3/2x+4
Step-by-step explanation:
First you have to plug in the points into y2-y1/x2-x1. This would make it -2-0/0+1. Simplify this to get -2/1 which is -2. This makes the slope -2. Then plug in the slope into point intercept form y-y1=m(x-x1) where m is the slope. This time, I will use the point (0,-2). Therefore, the equation will be y+2=1(x-0) which is equal to y+2 =x-0 which is equal to y=x-2.
This is how you do all of the problems. For problem 13-15, you know that f(0)=-1 is (0,-1) and f(3)=-10 is (3,-10). Then you can solve the problems. I will not explain every single problem but will give you the answers.
1 nickel = 5 cents
1 dime = 10 cents
The total = $2.40
There’s a total of 30 coins.
12 nickels = $0.60
18 dimes = $1.80
Isabelle has 12 nickels.
2(1)/((1)^2-3)^3
=2/(1-3)^3
=2/(-2)^3
=2/-8
=-1/4
Answer: Answer D
Step-by-step explanation:
A dilation will always create an image smaller or bigger than the pre-image making it not congruent since it changes in size.
If they are 35% off, then u r actually paying 65%....
65% of 82.88.....turn percent to a decimal...." of " means multiply....
0.65(82.88) = 53.87 <== sale price
