7x + 16 = 3x + 4 4x = -12 x = -3
The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth
X=4.2666666666667
7x is still the slope, no matter what x equals.
7x+x = 8x
7x+7=28x 28x-7x=7 21x=7 x=3
7x/3 = 105 7x = 315 x = 45
