Answer:

$y=-\frac{4}{9}x +\frac{2}{3}$

Step-by-step explanation:

I'm going to presume you want this linear equation in slope-intercept form, so start with:

$6=4x+9y$

Subtract $9y$ from both sides of the equation:

$-9y+6=4x$

Subtract $6$ from both sides of the equation:

$-9y=4x-6$

Divide both sides of the equation by the coefficient of $y$ , which is $-9$ :

$y=\frac{4}{-9}x +\frac{-6}{-9}$

Simplify:

$y=-\frac{4}{9}x +\frac{2}{3}$

To get on a certain toll road a driver has to take a card that lists the mile entrance point. The card also has a timestamp. Whe

kolezko [41]

Answer:

Step-by-step explanation:

This can happen because of the timestamp on the toll card. When you pass through the initial entrance point the timestamp marks the exact moment you passed. When you pass through the exit toll point the individual subtracts the current time from the time you entered the initial toll entrance. From this, he can easily determine the average speed that you were driving at. If the average speed is higher than the speed limit, it means that at some point between the two toll booths you were speeding and therefore they can give you a speeding ticket.

The ratio of credit card sales to cash sales at a store was 8:3. If the store had 144 cash sales, how many more credit card sale

Neko [114]

Answer:

There were 240 more credit card sales than cash sales.

Step-by-step explanation:

By using the ratio 8:3 I was able to determine that if there were 144 cash sales that would mean that there would be 384 credit card sales. However, the question asks "How many <u>more</u> credit card sales were there than cash sales?" Meaning that we need to find the difference. 384-144= 240.

This means that there were 240 <u>more</u> credit card sales than cash sales.

Hope this helped! If you have any questions about what I did please comment!

Help me with geometry pleasee ( Radom answers will be reported )

IrinaVladis [17]

A. jgb=jb+Eh/2
35+45=80/2=40 JGB =40°
B. since it is a line HGJ =180-40
HGJ= 140°
C. tangents to circles have equal lengths if they intercept the way gd and gf do eachother
set the lengths equal to themselves
4x+5=6x-8
-4x both sides
5=2x-8
+8 both sides
13=2x
÷2 both sides
x=13/2 or 6.5
Plug in
4 (6.5)+5=
26+5=31ft

What slope is perpendicular to x + 4y = 12

myrzilka [38]

Solve for the equation. The. Divide by 4 on both sides. And whatever you get for the slope. Write the opposite which will give you the perpendicular slope. For example: 1/4x is perpendicular to -4x
