A or b because the equality is the radius squared. when you are looking at the equations you need to know the center of the circle so count 7 blocks in to the middle and make sure it's even on all sides. the equation is opposite positive and negative *if the center were 2,-5 then the equation would be (x-2)*(y+5)*
Answer:
P(t)= 100t + 150
Step-by-step explanation:
If the price for 6 hours of studio time is 600 dollars, that means every hour the studio is used it costs 100 dollars. Since the fixed fee is 150 dollars, that is added to the cost of how many hours the studio is used.

Answer:
Step-by-step explanation:
Hello,
from the expression of f(x) we can say that there are two zeroes, -8 with a multiplicity of 1 and 4 with a multiplicity of 1.
So the image of the parabolic lens crosses the x-axis at two points:
(-8,0)
and
(4,0)
For information, I attached the graph of the function.
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
1. x = 5 2. y = 4 3. x = -2
Step-by-step explanation:
2x - y = 9 -5x + 2y = 13 3x + 4y = -6
<u>4x + y = 21</u> <u>5x + y = -1 </u> <u> 7x(-1) + 4y(-1) = -14(-1)</u> <(multiply all by -1)
<u>6x = 30 </u> <u>3y = 12</u> <u> -4x = 8</u>
6 6 3 3 4 4
x = 5 y = 4 x = -2
