Answer:
∠ B = 79°
Step-by-step explanation:
Since the angles are vertical then they are congruent, thus
6x - 11 = 5x + 4 ( subtract 5x from both sides )
x - 11 = 4 ( add 11 to both sides )
x = 15
Thus
∠ B = 5x + 4 = 5(15) + 4 = 75 + 4 = 79°
Answer:
(4,7), (-1,12)
Step-by-step explanation:
I will solve using elimination by subtracting one equation from the other.
y = x² - 4x + 7
- y = -x + 11
__________
0 = x² - 3x -4
0 = (x - 4)(x + 1)
x = 4, x = -1
We can plug in these values to get the corresponding y -values.
The solutions should be : (4,7), (-1,12)
Let it be for x miles.
40+15+0.25x=45+0.35x
10 =0.1x
x=100
The mile is 45+0.35*100= 80 or 40+15+0.25*100 =80
Answer:
(-3,1) and (-8,6)
Step-by-step explanation:
Hey gabymcarrillo!
The solution is always the place where the two lines intersect.
Our first answer: go 3 left on the x- axis, and then go 1 up on the y- axis. This results in (-3,1)
Our second answer: go 8 left on the x- axis, then go 6 up on the y- axis. This results in (-8,6)
