Hey there! :)
<em>First, let's substitute y with 0.8, and multiply by 8</em>
0.8 × 8 = 6.4
Here is the new equation:
4x + 6.4 = 40
<em>Now, subtract 6.4 from 40</em>
40 - 6.4 = 33.6
That means 4x = 33.6
<em>Divide both by 4</em>
4x ÷ 4 = x
33.6 ÷ 4 = 8.4
x = 8.4
Hope this helps :)
Answer:
1. can
2. less
3. 5
Step-by-step explanation:
To find out if Waclaw could make it to the gas station using 10 miles, we need to add the number of miles he has to go in order to reach his destination.

9 5/8 is less than 10, so he can make it to the gas station.
We can also find out the answer without even adding the numbers together, because both values are less than five, and when that happens, the sum cannot be 10 or more, so Waclaw can make it to the gas station.

Answer:
x = -4
Step-by-step explanation:
An undefined slope would look like a vertical line, up and down. This is shown using an x equals equation instead of a y equals equation.
Since the line goes vertically, you only need to look at the x-value to make the equation, since after doing x = -4 the line would keep going down until it touched (-4, -8).
The line would touch everything in the y-value but stay at x = -4.
Therefore the answer to this problem is x = -4. I've attached a picture (from desmos) showing what the graph of x = -4 would look like and how it touches the point (-4, -8).
