Answer:
i belive the answer is B
Step-by-step explanation:
Let the number sold of veggie pizza be a
The number sold of cheese pizza be b
a+b=25…1
A+7=b…2
Sub 2 into 1
a + a+7 = 25
2a+7=25
2a=18
a=9
Sub a=9 into 2
9+7=b
b=16
They sold 9 veggie pizza and 16 cheese pizza
The answer is B.
Function means every x corresponds to one unique y value. ACD all have duplicates correspondence.
Answer:
No
Step-by-step explanation:
If the lines are perpendicular then they will be the negative reciprocals of each other.
Calculate the slope using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)
= = -
Repeat the process with
(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)
= =
The slopes are not the negative reciprocal of each other, thus they are not perpendicular.
