Answer:
Choice A
Step-by-step explanation:
In each case, each equation has an equation of a line in y = mx + b form equaling another equation of a line in y = mx + b form. If the two sides are equal, it is the same equation, there are infinitely many solutions. If the sides are different, then if the slopes are different, the lines intersect at one point, and there is exactly 1 solution. If the slopes are equal, the lines are parallel, and there is no solution.
(Choice A) -10x-10=-10x-10
In Choice A, both sides of the equation are equal, so there are infinitely many solutions.
(Choice B) 10x-10=-10x+10
(Choice C) 10x-10=-10x-10
(Choice D) -10x-10=-10x+10
In choices B through D, the two sides are not equal, so there is either 1 solution (B and C since they have different slopes) or no solution (D since the slopes are equal).
C I'm pretty sure even though the real answer is 1979 so its d or c
Answer:
Y = Mx + b
Y = .20x + 80
80 —> consistent because it is the base payment regardless of commission.
Nothing because you can’t gain anything from 0
Answer:
x = 70
y = 40
Step-by-step explanation:
First, we need to find the measure of x.
As x and the angle 110 share a line, they must add up to 180 degrees. This means that the measure of x is 70.
The two ticks on the sides of the triangle indicate that these sides are equal in length. This also means that the corresponding angles will also be equal. This means that both x and the other angle are 70.
This means that we have two of the three angles in the triangle, so we can easily find the third, which is y.
