Hey there!!

Given :

g(x) = ax² + 24

and

g(4) = 8

g(4) = a(4)² +24

g(4) = 16a + 24

8 = 16a + 24

-16 = 16a

a = -1

The constant is -1.

g(-4) =?

g(-4) = -1(-4)² + 24

g(-4) = -16 + 24

g(-4) = 8

The answer is (A)

Hope it helps!

Find the distance between the points (-8,-6) and (4, 10)

never [62]

Answer:

d=20

Step-by-step explanation:

To find the distance between 2 points we use the distance formula

d = √(x2 - x1)²+(y2 - y1)²

The given points are (x1= -8, y1 = -6) and (x2 = 4, y2 = 10).

Substitute the given points into the distance formula.

d = √(4 + 8)²+(10 +6)²

d = √144+252

d= √400

d = 20

Which of the following is the solution set to the inequality −25x+14>20?

Bezzdna [24]

Answer:

Option C. $x < -15$

Step-by-step explanation:

The correct inequality is

$-\frac{2}{5}x+14 >20$

Solve for x

subtract 14 both sides

$-\frac{2}{5}x+14-14 >20-14$

$-\frac{2}{5}x >6$

Multiply by -1 both sides

$\frac{2}{5}x < -6$

Multiply by 5/2 both sides

$x < -6(\frac{5}{2})$

$x < -15$

Answer: a child ticket costs $14.50

Step-by-step explanation:

x=children ticket

x+4.50=adult ticket

3 children and 2 adult

3x+2(x+4.50)=81.50

3x+2x+9.00=81.50

5x+9.00=81.50

5x+9.00-9.00=81.50-9.00

5x=72.50

5x/5=72.50/5

x=14.50
