Answer:
-5
Step-by-step explanation:
-4x +10 =5(x +11)
-4x +10 =5x +55
-4x - 5x =55 - 10
-9x =45
x=-45 :9
x=-5
Answer:
D) 
Step-by-step explanation:
Basically, if you plug in the x and y-coordinates into an equation, both sides should work out to be equal to each other:
Since
, we can eliminate choice A
Since
, we can eliminate choice B
Since
, we can eliminate choice C
Therefore, since
, then D is correct. Also, 
Answer:
(42, 0)
Step-by-step explanation:
Since we know the slope and y-intercept we can write the equation of the line in slope-intercept form which is y = mx + b; therefore, the equation is y = -3/7x + 18. To find the x-intercept, we just plug in y = 0 which becomes:
0 = -3/7x + 18
-18 = -3/7x
x = 42
Answer:
129 and 51 degrees.
Step-by-step explanation:
Drawing a diagonal gives us a triangle with the opposite side = 12.4 and the adjacent side = 26.
tan x = 12.4 / 26
x = 25.497 degrees.
The other angle will be 90 - 25.497
= 64.503 degrees.
One of the diagonal angles is 180 - (2*25.497)
= 129 degrees
and the other is 180 - 129 = 51 degrees.
