A cashier has only one-dollar bills, quarters, and dimes. List 9 ways you could receive $2.50 in change.

write the equation of the line that passes through the given points (0,-1) and (-5,-7) Simplify your answer

USPshnik [31]

Answer:

y = 6/5 x-1 slope intercept form

6x-5y = 5 standard form

Step-by-step explanation:

We have the points (0,-1) and (-5,-7)

We can find the slope using

m = (y2-y1)/(x2-x1)

= (-7--1)/(-5-0)

= (-7+1)/(-5-0)

= -6/-5

= 6/5

We also have the y intercept ( when x=0) It is -1

We can use the slope intercept form of the equation y = mx+b

y = 6/5 x-1

Depending on what you mean when you say simplify your answer

We can put it in standard form ax+by = C

Multiply both sides by 5

5y =5* 6/5 x-1*5

5y = 6x-5

Subtract 6x from each side

-6x+5y = 6x-6x-5

-6x+5y = -5

Multiply by -1

6x-5y = 5

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (11, 4) → x₁ = 11, y₁ = 4

Point (5, 8) → x₂ = 5, y₂ = 8

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(5-11)^2+(8-4)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-6)^2+(4)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{36+16}$
[√Radical] Add: $\displaystyle d = \sqrt{52}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{13}$

At the toy store a $120 doll house is on sale for 40%? what is the amount

Sergeeva-Olga [200]

Answer:

$72

Step-by-step explanation:

Multiply $120*0.40 to see how much money is being taken off, this equals $48. Remember that this $48 is how much you want to remove from $120, so 120-48=72.
