Answer:

The final cost of her pizza is $11.90

Step-by-step explanation:

First we need to convert 15% into a decimal, which is 0.15.

Now we multiply $14 and 0.15.

$14 × 0.15 = $2.10.

Now we subtract $2.10 from $14.00.

$14.00 - $2.10 = $11.90

nikklg [1K]

Answer:

D. 15

Step-by-step explanation:

3x-10=2x+5

to solve subtract 2x from both sides

(3x - 2x) - 10 = 2x + 5 - 2x

add 10 to both sides

x -10 + 10 = 5 + 10

x = 15

The graph of a linear relationship has a slope of -5 and passes through the point (2,-12). Write the equation of the line in slo
kakasveta [241]

Answer:

To graph the line mark off the 2 points and draw a line through them.

Step-by-step explanation:

The slope = (-2-7) / (-3-0)

= -9/-3

= 3.

The value of b is found using the point-slope form of a line:

y - y1 = m(x - x1)

using m = 3, (x1, y1) = (0, 7):

y - 7 = 3(x - 0)

y = 3x + 7.

What is the equation of the axis of symmetry of a parabola if its x-intercepts are -3 and 7?
Ostrovityanka [42]
This is a parabola, meaning the equation is a quadratic, so it has 2 roots or x-intercepts, keeping in mind that vertex will lie half-way between those intercepts.

so what's the x-value halfway between -3 and 7?  yeap, you guessed it, 2.

so the axis of symmetry for this vertical parabola will be at x = 2.
