Keith received a gift card of $90 for a pizza restaurant. The restaurant charges $15 per pizza. Mary received a gift card of $11

stepan [7]

Answer:

a)Amount of money left on Keith's card in dollars = $90 - $15x

= $(90 - 15)

b) Amount of money left on Mary's card in dollars= $110 - $20x

= $(110 - 20x)

c) Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.

$90 - 15x = $110 - 20x

Step-by-step explanation:

Let x be the number of pizzas purchased. For each card, write an expression for the amount of money left on the card after purchasing x pizzas.

For Keith

Keith received a gift card of $90 for a pizza restaurant. The restaurant charges $15 per pizza.

x numbers of pizza costs = $15x

Hence, the amount of money left on Keith's card after purchasing x pizzas =

$90 - $15x

For Mary,

Mary received a gift card of $110 for a different pizza restaurant. The restaurant charges $20 per pizza.

Hence, x number of pizzas cost =$20 × x

= $20x

Therefore, the amount of money left on Mary's card after she buys x pizzas =

$110 - $20x

Amount of money left on Keith's card in dollars = __________

Amount of money left on Mary's card in dollars=____________

Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.

To find the equation that shows that the two cards have the same amount of money =

Equation 1 = Equation 2

$90 - 15x = $110 - 20x

Collect like terms

-15x + 20x = $110 - $90

5x = 20

x = 20/5

x = 4

Hence, anytime Keith and Mary buys 4 pizzas their gift card will have the same amount of money left on them.

What is an equation in slope-intercept form for the line that passes through the points (1, -3) and (3, 1)?

tensa zangetsu [6.8K]

First we need to find the slope:

Slope formula= $\frac{y2-y1}{x2-x1}$

Plug in your given values from the coordinate
Slope = $\frac{1-(-3)}{3-1}$

When we have 2 "-"'s together they turn into a + sign so we add.
Slope = $\frac{1+3=4}{3-1=2}$
Slope = $\frac{4}{2}$

Simplify (in this case divide) the slope:
Slope = $2$

slope-intercept form is:
y=mx+b
Where m=slope
b=y-intercept

So far we have:
y=2x+b

To find b all we have to do is pick any given coordinate and plug it in:
I chose (3,1)

so we plug that in the equation
1=6+b

Now solve for b:
1=6+b
subtract 6 from both sides
b=-5

Final answer:
y=2x-5 (D)
