Answer:19+3x
Step-by-step explanation:
4+3(5+x)
Open bracket
4+15+3x
19+3x
Answer:
Slope is 5.
Step-by-step explanation:
y + 3x = 8x -7
y = 5x - 7
coefficient in front of x is the slope/rate of change once you get the equation slope intercept for y = mx + b. m is the slope.
Answer: 
Step-by-step explanation:
Find the x-coordinate of the vertex with this formula:

In this case:

Substituting values, we get:
Now we can substitute the coordinates of the vertex into the equation
and then solve for "c".
Then:

Answer:
Question 2.) 16
144÷9=16
Question 3.) 16
16÷12=1.33... and all the others equal 1.33... as well
Question 4.) 20
20÷16=1.25 and all tho others equal 1.25 as well
Question 5.)12
8÷12=0.66... and all the others equal 0.66.... as well
I hope this is good enough for you:
