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

Answer:
-21
Step-by-step explanation:
x3-3y
putting values in the equation
(-3)(3)-3(4)
-9-12
since the sign is minus - and - both are added but the answer will remain in minus
-21
Do 12.64 divided by 4. That is each person’s cost of pizza. Then add 0.95 to the cost of pizza. That is your total.
