I think it would be b because if you use the midpt formula it’d turn out to be that ?

$y=ax^2+bx+c\\\\\text{Axis of symmetry:}\ x=\dfrac{-b}{2a}$

$\text{We have:}\\\\y=4x^2+16x-18\\\\a=4;\ b=16;\ c=-18\\\\x=\dfrac{-16}{2\cdot4}=\dfrac{-16}{8}=-2$

Answer: A.

4x-5=2x+7 midpoint segmen

Bogdan [553]

Answer:

x = 6

Step-by-step explanation:

The way to solve this is by subtracting 2x from both sides. Now we have

2x-5=7

Then we add 5 from both sides. Now we have

2x=12

We do this because we want X by itself

Then we divide by 2 on both sides and now we have

x = 6

Which of the following is a solution to the second order differential equation LaTeX: y''=-4y y ″ = − 4 y ? To answer this quest

Paraphin [41]

Answer:

y = sin(2t)
y = cos(2t)

Step-by-step explanation:

In the case of each of the answers listed above, the second derivative is equal to -4 times the function, as required by the differential equation.

For y = 2/3t^3, the second derivative is 4t, not -4y.

For y = e^(2t), the second derivative is 4y, not -4y.

The graph shows the sum of the second derivative and 4y is zero for the answers indicated above, and not zero for the other two proposed answers.

$180^{\circ} = (2x + 45)^{\circ} + x^{\circ}\\180^{\circ} = 2x^{\circ} + 45^{\circ} + x^{\circ}\\180^{\circ} - 45^{\circ} = 2x^{\circ} + x^{\circ}\\135^{\circ} = 3x^{\circ}\\x^{\circ} = 45^{\circ}$

Sam is trying to determine which cell phone and service plan to buy for his mother. The first phone costs $100 and $55 per month

vodomira [7]

Answer:

13 months

Step-by-step explanation:

x is the number of months

first phone:

f(x) = 55x + 100

second phone:

g(x) = 51x + 150

now set up the inequality

g(x)<f(x)

51x + 150 < 55x + 100

Solve the inequality:

51x + 150 < 55x + 100

(get everything on the correct sides... combine the like terms)

51x - 55x < 100 - 150

-4x < -50

divide both sides by -4 (don't forget to flip the inequality sign when dividing by a negative number.)

x > 50/4

x > 12.5

round up to 13
