Match each system with the number of solutions. 1. y = -5-x, y = x + 5 2 2. y = 4(1.2)x, y = x + 7 1 3. y = (0.5)x, y = 6 0

The reason why most of the answers regarding this problem say "all of them have only one solution" is because the x's in the equations are meant to be raised to a power.

Step-by-step explanation:

So, y=-5^-x and y=x+5 when graphed would have 0 solutions.

y=4(1.2)^x and y=x+7 would have two solutions.

And y=(0.5)^x and y=6 would have one solution.

a negative exponent is translated as follows:

so, we have

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
