Answer:
C. (-7, -15)
Step-by-step explanation:
Both the x- and the y-coordinates of a point in the third quadrant are negative. The given point C. (-7, -15) is the only one of the four choices that satisfies this criterion.
Let the number be x, then
x/12 <= 6
x <= 6 x 12
x <= 72
Answer:
He spent around $ 52.17 in each month.
Step-by-step explanation:
Last year the power bill price = $ 626.14 ≈ $ 626
We know that in a year 12 months. so power bill of each month in last year is calculated as follows
$ 52.17
Therefore he spent around $ 52.17 in each month.
Answer: 25
Step-by-step explanation:
Step-by-step explanation:
A quadratic graph will surely help you find the solutions
X2-x-2=0
x1=2 x2= -1
Substitute each of the x value in the original equation to get the y value
(2)^2-(2)-2= 0 (2,0)
(-1)^2-(-1)-2=-2 (-1,-2)
plot the coordinates on the graph,the graph should be a curve
