Yes they do have the same number of zeros
Answer:
y = 15x + 65
Step-by-step explanation:
To find the equation, we can use two points in the graph to find the parameters 'a' and 'b' in the equation:
y = ax + b
For the value x = 1, we have y = 80
For the value x = 9, we have y = 200
So we have that:
80 = a*1 + b
200 = a*9 + b
Making the second equation minus the first one, we have:
8a = 120
a = 15
Now we can find 'b':
80 = 15 + b
b = 65
So the equation is y = 15x + 65
That would be the slope of this straight line; it's 30 units / lesson, e. g., $30/lesson. The $25 is the registration and/or up-front cost.
Answer:
20%
Step-by-step explanation:
50+30=80
100-80=20
so you would pay 20%
Ask: Which two numbers add up to -12 and multiply to 32?
-8 and -4
Rewrite the expression using the above
<u>= (y - 4)(y - 8)</u>
