Answer:
A
Step-by-step explanation:
The lines cross or touch the X-Axis 4 times which means that there are 4 solutions.
Answer:
It’s y2-y1 over x2-x1
Y2 is 5 and y1 is 5
5-5
X2 is 7 and x1 is -2
7- negative 2
5-5 is 0
7- negative 2 is 9
Slope is 0

Answer:
CD = 45
Step-by-step explanation:
CE = 180
( x + 6 ) + ( 4x - 21 ) = 180
5x - 15 = 180
5x = 195
x = 39
substitute x in CD
CD = x + 6
CD = 39 + 6
CD = 45
Mean = (18 + 21 + 17 + 24 + 15) divided by 5
Mean = 95 divided by 5
Mean = 19
To find the equation we will put the values of x and y in the equations and then check if LHS=RHS.
Hence, Option B. y=5x+4 satisfies the system (1,9)
