Answer:
In slope intercept form, this equation is y = 6x + 8
Step-by-step explanation:
All you need to do to get this to slope intercept form is to distribute the term and then combine like terms.
y = 3(2x + 1) + 5 ----> Distribute
y = 6x + 3 + 5 ----> Combine like terms
y = 6x + 8

Answer:
2
Step-by-step explanation:
3(x+2)=12
Distribute:
3x+6=12
Subtract:
3x+6-6=12-6
3x=6
Divide:
x=2
Answer:
Step-by-step explanation:
f(x) = 2x² + 14x - 4
= 2(x² + 7x) - 4
= 2(x² +7x + 3.5²) - 2(3.5²) - 4
= 2(x+3.5)² - 28.5
vertex (3.5, -28.5) = (7/2, -57/2)
The vertical intercept is the y-intercept, i.e., f(0) = -4.
The x-intercepts are the values of x for which y=0.
2x² + 14x - 4 = 0
x = [-14±√(14²-4(2)(-4))]/[2(2)] = [-7±√57]/2 ≅ -7.27, 0.27
