Answer:

1. y=3x+3

2. y=3x+1

Step-by-step explanation:

Use y=mx+b

Sub (0,3) into y=mx+b

3=m(0)+b

b=3

Sub (3,9) into y=mx+3

9=m(3)+3

3m=6

m=2

EQUATION: y=3x+3

Sub (1,4) into y=mx+b

4=m(1)+b

b=4-m

Sub (3,10) into y=mx+(4-m)

10=3m+4-m

2m=6

m=3

b=4-m=4-3=1

EQUATION:y=3x+1

Find the equation of the line that passes through the point (7,5) and is perpendicular to the line 2x - 3y=6

balu736 [363]

$(7,5);\ \ \ \ 2x - 3y=6 \ \ / subtract \ 2x \ from \ each \ side \\ \\-3y = -2x + 6\ \ / divide \ each \term \ by \ (-3) \\ \\ y = \frac{2} {3}x -2\\ \\ The \ slope \ is :m _{1} = \frac{ 2}{3} \\ \\ If \ m_{1} \ and \ m _{2} \ are \ the \ gradients \ of \ two \ perpendicular \\ \\ lines \ we \ have \\\\\ m _{1}*m _{2} = -1$

$\frac{2}{3}\cdot m_{2}=-1\ \ / \cdot (\frac{3}{2})\\\\m_{2}=-\frac{3}{2}\\\\Now \ your \ equation \ of \ line \ passing \ through \ (7,5) would \ be: \\ \\ y=m_{2}x+b \\ \\5=-\frac{3}{2}\cdot 7 + b \\ \\ 5= -\frac{21}{2}+b\\ \\b=5+\frac{21}{2} \\ \\b= \frac{10}{2}+\frac{21}{2}\\ \\b= \frac{31}{2}\\\\b=15.5 \\ \\ y = -\frac{3}{2}x +15.5$

Chloe purchased a sweater that cost $24, and a shirt that cost 5/8 times as much as the sweater.What amount of change did Chloe

KatRina [158]

Answer:

Chloe received $11 as change if she gave the clerk $50

Step-by-step explanation:

We are given that Chloe purchased a sweater that cost $24, and a shirt that cost 5/8 times as much as the sweater.

Cost of sweater = $24

Cost of shirt = $\frac{5}{8} \times 24 = 15$

So, Total cost of shirt and sweater = 24+15=39

Now She gave $50 to clerk

So, Change received by her = 50-39=11

So, Chloe received $11 as change if she gave the clerk $50
