Answer:
Center (-5,4) radius 3
Step-by-step explanation:
The standard equation of a circle is
(x-h)^2+(y-k)^2=r^2
where the center is (h,k) and r is the radius
so h=-5 in this case and k is 4
r^2=9 so r=3
Quadratic equations CAN be used to solve word problems so the answer to your question is false
Answer:
d. $43.00
Step-by-step explanation:
Karli's total cost is ...
total cost = material cost + labor cost
= ($8.00/10 gal)·(5 gal) + ($13.00/h)·(3 h)
= $4.00 + $39.00
= $43.00
If you would like to solve the system of linear equations, you can do this using the following steps:
2x - y = -1 ... y = 2x + 1
2x + y = -7 ... y = -7 - 2x
The correct result would be: y = 2x + 1, <span>2x + y = -7.</span>
