Answer:
The x intercept would be -4
Step-by-step explanation:
First, get your numbers into slope intercept form, y = mx + b. This would be y = -1/2x - 2. Then, replace y for 0, which would be 0 = -1/2x - 2. Add 2 on both sides to get 2 = -1/2x. then, multiply each side by -2, you end up with -4 = x, which means -4 is your x intercept.

Step-by-step explanation:
Answer:\frac{s-a}{n-1}
Step-by-step explanation:
formula, s=a+(n-1)d
1. get rid of the a on d's side by subtracting it from both sides.
s=a+(n-1)d becomes s-a=(n-1)d
2. get rid of (n-1) by dividing it from both sides. s-a=(n-1)d becomes
\frac{s-a}{n-1} =d
Answer:
5/16 i think
Step-by-step explanation:
The ratio 21:14 when divided by 7 on each side, is the smallest ratio that has the same value as 21:14. this becomes 3:2
then multiply both sides by a few different numbers on both sides each ,
for example, 3:2 is the same as
6:4 (3:2 times 2)
9:6 (3:2 times 3)
12:8 (3:2 times 4)
15:10 (3:2 times 5) and so on
the ratio of the right number I
divided by the left on all of them is 1.5
so,
14/10 equals 1.4 (nope)
8/4 equals 2 (nope)
9/6 equals 1.5 (yay)
12/21 equals 0.57 (Lol)
So your answer is 9:6
