Franko's Pizza is selling their pizzas 35% cheaper than usual. If a pizza normally cost $12 how much is it now? (Show Work)

I need to know if 4(x + y) and 4y + 4x are equivelent please

PolarNik [594]

Yes they are because you use distributive property and 4(x+y) you have to do 4•x= 4x and 4•y=4y so it would be 4y+4x

The vertex of this parabola is at (3-2). When the value is 4 the

Sphinxa [80]

Answer:

D

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here (h, k ) = (3, - 2 ) , then

y = a(x - 3)² - 2

to find a substitute the point (4, 3 ) into the equation

3 = a(4 - 3)² - 2 ( add 2 to both sides )

5 = a × 1² = a

the coefficient of the squared expression is 5

If it takes 9 yards of material to make curtains for 3 windows, how much material is needed

kap26 [50]

Answer:

33 material

Step-by-step explanation:

A simple proportions problem.

9:3 = 3:1

so it takes 3 yards to make 1 window

We multiply both sides by 11 to get

33:11 which now we get 33 material

A speedometer has a percent error of 10%. The actual speed of the car is 40 mph. Select from the drop-down menus to correctly co

rodikova [14]

Answer

The speedometer is likely to show the speed is either 36.0 mph or 44.0 mph.

To prove

Formula

$Percentage\ error = \frac{error\times 100}{Exact\ value}$

Where error = |Approx value - Exact value |

First case

As given

A speedometer has a percent error of 10%. The actual speed of the car is 40 mph.

Here

Percentage error = 10%

Exact value = 40 mph

error = - (Approx value - Exact value )

= - (Approx value - 40 )

= - Approx value + 40

Put in the formula

$10 = \frac{(-Approx\ value + 40)\times 100}{40}$

$400 = {(-Approx\ value + 40)\times 100}$

$\frac{400}{100} =-Approx\ value + 40$

$\4 =-Approx\ value + 40$

Thus

Approx value = 40 - 4

Approx value = 36 mph

Therefore Option (b) is correct .

Second Case

error = (Approx value - Exact value )

= (Approx value - 40 )

= Approx value - 40

Put in the formula

$10 = \frac{(Approx\ value - 40)\times 100}{40}$

$400 = {(Approx\ value - 40)\times 100}$

$\frac{400}{100} = Approx\ value - 40$

$\4 = Approx\ value - 40$

Thus

Approx value = 40 + 4

Approx value = 44 mph

Therefore Option (c) is correct .

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's write the equation of line in slope point form ~

$\qquad \sf \dashrightarrow \:y - y1 = m(x - x1)$

$\qquad \sf \dashrightarrow \:y -2 = 3(x -1)$

$\qquad \sf \dashrightarrow \:y -2 = 3x - 3$

$\qquad \sf \dashrightarrow \:y = 3x -1$

Now, let's use this equation of line to plot two points ~

when x = 0, y = (3 × 0) - 1 = - 1

when x = -1, y = (3 × -1) -1 = -4

Now, plot these points on graph ~

(0 , -1) and (-1, -4)
