Answer:
Step-by-step explanation:
to find slope: the formula is:
(y2-y1) / (x2-x1)
in this case it is:
(-9-(-2)) / (-10-(-2))
-7/-8
and thats the slope (that was for question one, and also an example, now do the same for questions 2, 3 and 4!!
hope thsi helps!!
Answer:
a = - 10
Step-by-step explanation:
Given
= - 2
a is divided by 2. The inverse operation to division is multiplication, thus
Multiply both sides by 5 to clear the fraction
a = 5 × - 2 = - 10
25 is about 3.32% of 752.
10³ · x = 630
x = ?
10³ = 10 × 10 × 10 = 1,000
630 ÷ 1000 = x
630 ÷ 1000 = 0.63
x = 0.63
So we have:
10³ · 0.63 = 630
