Answer:
9
Step-by-step explanation:
9/9=1
27/9=3
Answer:
C
Step-by-step explanation:
In the equation y = -x - 4, the gradient is -1.
While in the second equation,
5x + 5y = 20
y = -x + 4
So the gradient is -1 too
Both sides are not perpendicular to each other because if you apply the formula, m1m2 = -1, and if substitute both gradient, (-1)(-1) = 1 ≠ -1
Therefore, no they are not perpendicular but parallel instead.
Find the unit rate.
39/6 = 6.5
$6.50 an hour
multiply this by ten to find the cost for 10 hours
$6.5 x 10 = $65
she will earn $65 in ten hours.
hope this helps! :D
so namely, the "common difference" d = -4, and the first term a₁ = 7.
