Consider the function f(x)=mb+b, where m > 0. If the value of b decreases, but the value of m remains the same, what will happen to the x-intercept? A. The x-intercept decreases.
B. The x-intercept increases.
C. The x-intercept approaches zero.
D. The x-intercept remains the same.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

2x^2+5x+17

your welcome. : )
