Answer:
y = 8x + 9
Step-by-step explanation:
Parallel lines have the same gradient,
So m = 8
y = 8x + c
When x = -1 ,y = 1
1 = 8(-1) + c
c = 9
y = 8x + 9
Answer:
Step-by-step explanation:
425 / 2 = 212.5
212.5 - 25 = 187.5
187.5 is the answer because terry had 25 less and the score was combined
First you want to subtract 21.91 from 68.77 which will leave you with 46.86 then you divide 46.86 by 1.72 then you get about 27.22 so 27.20 gigs were used
Perimeter of rectangle=66
length of rectangle=L
width of rectangle=w
P of a rect.= 2(length)+ 2(width)
66= 2L+2w
if the length is 7in more than the width, then
L=7+w
Now we will substitute 7+w in for L. Here is our new equation:
66=2(7+w) + 2w
Solve for w
66=14+2w+2w
66=14+4w
52=4w
w=13
L=7+13, so L=20
I hooe this is explained well enough
