Subsitute 9 for y
9=y=9x-9
add 9 to both sides
9+9=9x+9-9
18=9x+0
18=9x
divide by 9
2=x
y=9
x=2
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
Vertical Angles are the congruent angles opposite each other when two lines cross
see the attached figure to better understand the problem
m<ACD=m<BCE ------> by vertical angles
m<ACB=m<DCE ----> by vertical angles
Answer:
10.
Step-by-step explanation:
x^2 + 5x = 150
x^2 + 5x - 150 = 0
This equation will factor:
(x - 10)(x + 15) = 0
x - 10 = 0 or x + 15 = 0, so:
x = 10 or -15.
Answer:
y = -3x + 6
Step-by-step explanation:
All you can do is change the y intercept, changing the slope will make the line not parallel to the original
Answer:
Catalina skates a total of 120 feet
Step-by-step explanation:
In order to determine how far she skates, create a right triangle. We know each legs' value with one being 30 and the other 40. Now we can find the hypotenuse by using the Pythagorean Theorem.
a^2 + b^2 = c^2
30^2 + 40^2= c^2
900 + 1600 = c^2
2500 = c^2
50 = c
Now that we have all 3 sides of the right triangle, add them together for the total distance.
30 + 40 + 50 = 120 feet
