Answer:
slope=1/14
Step-by-step explanation:
y=8x+6x-32
14x-y-32=0
slope=-b/a
=1/14
Answer:
(6.8, 1.3)
Step-by-step explanation:
<u>Given</u>:
A(-3, -5), B(11, 4)
<u>Find</u>:
P such that AP/AB = 7/10
<u>Solution</u>:
Using the desired relation, we have ...
(P -A)/(B -A) = 7/10
10(P -A) = 7(B -A) . . . . . multiply by 10(B-A)
10P = 7B +3A . . . . . . . . add 10A to both sides
10P = 7(11, 4) +3(-3, -5) = (77 -9, 28 -15) = (68, 13)
P = (68, 13)/10 = (6.8, 1.3)
The point 7/10 of the way from A to B is (6.8, 1.3).
Answer:
C would be the answer!
Step-by-step explanation:
The line goes down so its a negative and if you count the dots it is -3/5 which double is - 6/10:)
X = first film....y = second film
x + y = 132
x = 2y - 3
2y - 3 + y = 132
3y - 3 = 132
3y = 132 + 3
3y = 135
y = 135/3
y = 45......so the 2nd film lasted 45 minutes
x = 2y - 3
x = 2(45) - 3
x = 90 - 3
x = 87 <=== the first film lasted 87 minutes
