The sum and product of two linear functions are shown. Which statements can be used to describe the original functions f(x) and g(x)? Select three options.

When added, the sum of the y-intercepts must be 8.
When multiplied, the product of the y-intercepts must be 8.
Either f(x) or g(x) has a positive rate of change and the other has a negative rate of change.
f(x) could have a rate of change equal to 3 and g(x) could have a rate of change of –3.
f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of –1.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

is should be y = 5x

step-by-step explanation:

correct me if im wrong

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.
