Answer:
Step-by-step explanation:
Point-slope equation for line of slope -1 that passes through (-3,4):
y-4 = -1(x+3)
Answer:
130 calories in the ice cream and 500 calories in the pie.
Step-by-step explanation:
Let the amount of calories in the scoop of ice cream be x. the amount of calories in the piece of pie be 3x-20. we know that x+3x-20=500.
4x-20=500
If we add twenty to both sides, we end up with:
4x=520
Divide both sides by four, and you get x=130.
there are 130 calories in the scoop of ice cream and 130*4-20=500 calories in the pie.
Answer:The answer is 320
Step-by-step explanation:
16x20=320
Y=2x-3
When you plug it in
2 times 2 is 4 minus 3 is 1
2 times 3 is 6 minus 3 is 3
2 times 5 is 10 minus 3 is 7
2 times 7 is 14 minus 3 is 11
Just plug in the numbers and you will see that
Y=2x-3 is the correct equation for those functions.
