2. 5(x-1)=-3x+35
5x-5=-3x+35
5x=-3x+30
2x=30
x=15
Answer:
the first 3 consecutive numbers
x, x +1, x +2 = 270
x+x+1+x+2 =270
3x +3 =270
collect like terms
3x =270 -3
3x =267
divide both sides by 3
x =89
first, spread the parenthesis. y+2=1/2x-1.5
second, add 1.5 to both sides. y+3.5=1/2x
third, multiply by 2. 2y+7=x
if you are solving for y, do not do the third step, instead, subtract by 3.5. y=x-3.5
hope this helps!
ANSWER: x=2y+7 or y=x-3.5
(-5,2) concave up
Hope this helps :)
<span>The ratio of sides is, 8:10 = 4:5
squaring it yields, 16:25
the ratio of the area is 16:25
