<span>Simplifying 4x + -1y = 10 Solving 4x + -1y = 10 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. 4x + -1y + y = 10 + y Combine like terms: -1y + y = 0 4x + 0 = 10 + y 4x = 10 + y Divide each side by '4'. x = 2.5 + 0.25y Simplifying x = 2.5 + 0.25y</span>

How many miles did Byron drive? Please do not guess!

Triss [41]

<h3>Answer: 10 miles</h3>

=======================================================

Explanation:

The distance from his house to the gas station is 5 miles. We can find this by counting out the number of spaces between the two points (since the chart indicates that 1 unit = 1 mile). Or we can subtract the x coordinates to get 8-3 = 5. This only works because the y coordinates of each point are the same value.

To find the distance from the gas station to the market, we subtract the y coordinates this time. This only works due to the x coordinates being the same. We get a distance of 8-3 = 5 miles.

Overall, the total distance Byron drives is 5+5 = 10 miles.

4x-2y<-2<br><br>a) (2,8) b) (0,1) c) (3,7) d) (5,8)

Answer:

a) (2, 8)

Step-by-step explanation:

The easiest way is to insert the coordinates into the inequality.

a) (2, 8)

$\begin{array}{rcl}4(2) - 2(8) & < & -2\\8 - 16 & < & -2\\-8 &< & -2\\\end{array}\\\textbf{TRUE}$

b) (0, 1)

$\begin{array}{rcl}4(0) - 2(1) & < & -2\\0 - 2 & < & -2\\-2 &< & -2\\\end{array}\\\text{False}$

c) (3, 7)

$\begin{array}{rcl}4(3) - 2(7) & < & -2\\12 - 14 & < & -2\\-2 &< & -2\\\end{array}\\\text{False}$

d) (5, 8)

$\begin{array}{rcl}4(5) - 2(8) & < & -2\\20 - 16 & < & -2\\4 &< & -2\\\end{array}\\\text{False}$

You could also plot the inequality and test the points. You would get a graph like the one below. Point (2, 8) is the only one that satisfies the inequality. Points (0, 1) and (3, 7) do not satisfy the inequality because they are on a dashed line.
