#15(A)
First Bike
$380 - $190 ($380 * 0.50) = $190

2nd Bike
$380 - $114 ( $380 * 0.30) = $266
$266 - $53.20 ($266 * 0.20) = $212.80

#15 (B)
Eliza should buy the first bike because it is cheaper. $190 < $212.80

#16
$57 + $28.50 ($57 * .50) = $85.50

Solve the system of equations.
kakasveta [241]

Answer:

C   (-6, 2)

Step-by-step explanation:

in order to solve this system of equation, we would say that let

y = 5x + 32................................equation 1

y = -4x - 22.........................................equation2

substitute equation 1 into equation 2

we have,

5x + 32 = -4x - 22

combine the like terms

5x +4x + 32 = -22

9x = -22-32

9x = - 54

divide both sides by the coefficient of x which is 9

9x/9 = -54/9

x = -6

put x =-6 into equation 1

y = 5x + 32................................equation 1

y = 5(-6) + 32

y = -30 + 32

y = 2

therefore the value of x and y is -6 and 2 respectively

Find the slope of the line through each pair of point
Rashid [163]

The slope of the line passes through (-6, 3) and (1, 5) is \frac{2}{7}

<u>Solution:</u>

Given, two points are (- 6, 3) and (1, 5)  

We have to find the slope of a line that passes through the above given two points

Slope of a line that pass through \left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right) is given as:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

\text { Here, in our problem, } x_{1}=-6, y_{1}=3 \text { and } x_{2}=1, y_{2}=5

\text { Slope } m=\frac{5-3}{1-(-6)}=\frac{2}{1+6}=\frac{2}{7}

Hence, the slope the line that passes through the given points is \frac{2}{7}
