Answer:
y = -7/3x + 10
Step-by-step explanation:
Step 1: Find the slope of the perpendicular line
Do this by taking the negative inverse of the first line
m = -7/3
Step 2: Find <em>b</em>
y = mx + b
y = -7/3x + b
3 = -7/3(3) + b
3 = -7 + b
b = 10
You should get y = -7/3x + 10 as your final answer.
Answer:
= 2 × 625 – 5 × 125 + 25 + 3 × 5 + 2
=1250 – 625 + 25 + 15 +2
= 1292 – 625
= 667
Answer:
Step-by-step explanation:
Time for first race 57.9seconds
x=time for first half of race
x-4.7=second half of race
Equations is
x + (x-4.7)=57.9
2x-4.7=57.9
2x=57.9+4.7
2x=62.6
x=31.3
Check answer
31.3 + (31.3-4.7)=57.9
31.3 +26.6=57.9
57.9=57.9
She will need 13 one-fourth cups.
(4 one-fourths times 3 = 12 cups plus another one-fourth)
Hope this helps you!!!
