Answer:
1. d. x-intercept is -4; y-intercept is 8.
2.d. x-intercept is 16; y-intercept is 20
3. b. -x+6y=24
4. a. 4.75k+2.25p=22
Step-by-step explanation:
1. -10x+5y=40
to find the y intercept let x =0
5y = 40
divide by 5
y = 40/5 = 8
to find the x intercept let y =0
-10x = 40
divide by -10
x = 40/-10
x=-4
2. 5x+4y=80
to find the y intercept let x =0
4y = 80
divide by 4
y = 80/4 = 20
to find the x intercept let y =0
5x = 80
divide by 5
x = 80/5
x=16
3. Write y=1/6x+4 in standard form using integers.
Ax+by =c
multiply each side by 6
6y = 6* (1/6 x + 4)
6y = x+24
subtract x from each side
-x+6y = x-x+24
-x +6y = 24
4. lbs of kumquats * price/per + lbs of pears * price/lb =22
k * 4.75 + p * 2.25 =22
4.75k + 2.75p = 22
Answer: Your answer is A and D
Step-by-step explanation: Sure hope this helps you. And pls mark me as brainiest
The answer is 50 rotations/sec
The way you get that answer is by simply dividing your 2000 rotations by 40 seconds
21 divide by 4 is 5.25. She travels 5.25 miles per hour. 42 divide by 5.25 is 8. It would take 8 hours for Shelly to bike 42 miles.
You would have 6 quarters and 4 dimes
6 x $0.25 = $1.50
4 x $0.10 = $0.40
= $1.90
