Answer:

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Rewrite the expression with rational exponents.

Marina CMI [18]

Answer:

( $\sqrt[5]{x}$ )^7

Step-by-step explanation:

to cancel out the radical you do the exponent inside and divide it by the out side one so it will be 7/5 so make it x to the expontent of 7/5 and to do rational exponets it will be (^5radicalx)^7

M(6, 6) is the midpoint of . The coordinates of S are (8, 9). What are the coordinates of R?

Sidana [21]

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
R&({{ x}}\quad ,&{{ y}})\quad 
% (c,d)
S&({{ 8}}\quad ,&{{ 9}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)$

$\bf \left( \cfrac{8+x}{2}~~,~~\cfrac{9+y}{2} \right)=\stackrel{midpoint}{M(6,6)}\implies 
\begin{cases}
\cfrac{8+x}{2}=6\\\\
8+x=12\\
\boxed{x=4}\\
----------\\
\cfrac{9+y}{2}=6\\\\
9+y=12\\
\boxed{y=3}
\end{cases}$

Lamar has 1,354.5 kilograms of potatoes to deliver equally to 18 stores. 12 of the stores are in the Bronx. How many kilograms o

Helen [10]

Answer:

deliver in 12 stores in the Bronx = 903 kg

Step-by-step explanation:

given data

potatoes weight = 1354.5 kg

no of store = 18

store in Bronx = 12

to find out

How many kilograms of potatoes will be delivered to stores in the Bronx

solution

first we find the 1 store potatoes deliver weight that is

1 store deliver = $\frac{total weight}{total store}$ ............1

put here value in equation 1

1 store deliver = $\frac{1354.5}{18}$

1 store deliver = 75.25 kg

deliver in 12 stores in the Bronx are

deliver in 12 stores in the Bronx = weight of 1 store deliver × 12

deliver in 12 stores in the Bronx = 75.25 × 12

deliver in 12 stores in the Bronx = 903 kg

You need to spend at least $50 in one day to receive a store discount. You have already spent $30. Let s be the amount of money

Allushta [10]

Answer: s + 30 ≥ 50; s ≥ 20

Step-by-step explanation:

let s be the amount you have yet to spend in order to reach $50 or more

you already have $30.

This means you need to spend at least $20 more ($50 - $30 = $20)

S can be greater than or equal to $20 because your total will be 50 or more, therefore qualifying for the discount.
