What is the solution of the system of equations?
y = 1/8x - 1
-5x + 4y = -13

Step-by-step explanation:

y = 1/8x - 1sub this back in for y in the other equation

-5x + 4y = -13

-5x + 4(1/8x - 1) = -13

-5x + 1/2x - 4 = -13multiple everything by 2 to get rid of the fraction

-5x(2) + 1/2x(2) - 4(2) = -13(2)

-10x + 1x - 8 = - 26

- 9x = -26 + 8

-9x = - 18

x = 18/9

x = 2now sub 2 in for x in either of the original equations to find y

y = 1/8x - 1

y = 1/8(2) - 1

y = 1/4 - 4/4

y = -3/4

so ur solution is : (2,-3/4) <===

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
