2. y=2x+3
When x =0 and y= something, the 'something' is your y-intercept which is b in the y=mx+b formula. Then we look at what is changed in the x and y value to determine the m part. the x increase by 1 and y increase by 2 so the m part is 2.
3. y=-7x
Same as the last one, there is no y-inter this time because the y=0 when x=0/ So the y deceased by 7 each time and x incease by 1 so it is -7 for the m part.
Not exactly sure if I’m right but
1. $56 < $60
2. $60 - $36 = $24/4 hours = 6.
36+24 = 60, we want to use LESS than 60 so we use see how much it’ll take to spend 5 hours for parking.
5 x $4 = $20.
$36 + $20 = $56
I’m not exactly sure though...
2.8 I got that same on on khan academy it’s 2.8 trust me
Hi!
<h3>Use the distribution property</h3>
1.4t — 0.4 * t - 0.4 * —3.1 = 5.8
1.4t — 0.4t - 1.24 = 5.8
<h3>Simplify</h3>
1t - 1.24 = 5.8
<h3>Add 1.24 to both sides</h3>
1t - 1.24 + 1.24 = 5.8 + 1.24
1t = 7.04
<u>t = 7.04</u>
<h2>The answer is t = 7.04</h2>
Hope this helps! :)

2x-4y=8
Add 4y to each side to separate the variables, since you want to solve for x let be on the left
2x=4y+8
Divide the entire equation by 2 to allow x to stand alone
x=2y+4
And I have to type some more so it will let me answer the question so here ya go
