75) y=mx+b. plug in slope and point
2=(3/2)(1)+b
2=(3/2)+b. solve for b
b=1/2. plug back into original question
y=(3/2)x+(1/2) multiply by 2 to get rid of fraction
(y=(3/2)x+(1/2))*2.
2y=3x+1. subtract over the 3x
-3x+2y=1
Same would be done with the other 4 problems.
She would type 15 words a minute. you divide 1125 by 15 and you get 15
answer:15
hopes this helps
Answer:
If you see the top and bottom of the figures are getting smaller by two, so for A its getting smaller by two, and for B it will just be a solid set of four lines
Step-by-step explanation: make sure you put it in you own words
Hey there! I'll try to provide you with my best answer.
Answer: x = 120 and y = 150
(x / y) = (4 / 5)
1) 5x = 4y
( (x + 20 ) / (y - 20) ) = (14 / 13)
cross multiply fractions
13(x + 20) = 14(y - 20)
13x + 260 = 14y - 280
2) 13x - 14y = -540
solve equation 1) for x
x = 4y/5
now substitute for x in equation 2)
13(4y/5) - 14y = -540
multiply both sides of = by 5
52y - 70y = -2700
-18y = -2700
y = 150
x = 4(150) / 5 = 120
x = 120 and y = 150
check answers (proof):
120 / 150 = 12 / 15 = 4 / 5
(120+20) / (150-20) = 140 / 130 = 14 / 13
