Hey there! I'm happy to help!
First, let's find the slope. To find it, you divide the difference in two y values by the difference in the corresponding x values.
The x values are what you can choose. You can choose the number of minutes you choose, but you cannot directly choose the cost. You control the minutes, which dictates what the cost is. So, the minutes are our x values and the costs are our y values.
Let's use the points (500,62) and (750,77).
We subtract the y values.
77-62=15
We subtract the x values.
750-500=250
We divide these.
15/250=0.06
This means that our slope is 0.06, which means that for every minute the cost goes up by six cents.
The slope intercept equation is y=mx+b. The m is slope and b is y-intercept. We already have the slope, but we need the y-intercept. We can plug in the slope and one point on the line to solve for b.
62=0.06(500)+b
Flip the equation so b is on the left.
0.06(500)+b=62
30+b=62
Subtract 30 from both sides.
b=32
Therefore, our equation is y=0.06x+32.
Have a wonderful day! :D

He should expand the 1/4 on the barker (x+12) then he will have 1/4x+3 = 2 then he should subtract the 3 from the 2 meaning he will be left with 1/4x = -1 and then he should multiply the left hand side and the right hand side with 4 in order to get rid from the 1/4 so the answer is x = -4
x > 1 is the required solution of the given inequality - 3x + 7 < 4. This can be obtained by solving the inequality the same way as we solve an algebraic equation.
<h3>Solve the inequality:</h3>
The inequality can be solved as the same way as we solve an algebraic equation.
- Combine the terms with variables to one side and constants to other side.
- To multiply the whole inequality with negative terms we reverse the sign of the inequality.
Here in the question the inequality to be solved is given:
- 3x + 7 < 4
By subtracting 7 from both sides of the inequality we get,
⇒ - 3x + 7 - 7 < 4 - 7
⇒ - 3x < - 3
To make the side of the inequality with variable x positive we multiply the whole equation with - 1, then we have to reverse the sign of inequality since we have to multiply the whole inequality with a negative term,
we get,
⇒ 3 x > 3
Now finally by dividing the whole inequality by 3 we get,
⇒ x > 1
The number line representation can be done by marking values from 1 to numbers greater than 1.
Hence x > 1 is the required solution of the given inequality - 3x + 7 < 4.
