Answer:

31/45.

Step-by-step explanation:

Give them common denominators, and then if you have to add them, add them if subtract, then subtract, if multiply, then multiply. And if you have to divide it to make the fraction smaller, then do so.

4(x − 3) − 5(x + 1) = 3 Which of the following algebraic properties is not needed to solve this equation?

skelet666 [1.2K]

Hi there!

To solve this problem, you need to use the distributive property. You distribute the 4 inside the parenthesis as well as the 5.

Hope this helps!

12. The white triangle drawn on the road sign in the picture has a height of 8" and a base of 5". Which formula would be correct

nevsk [136]

Step-by-step explanation:

I think you did not copy the correct information of your answer options here.

because, as you wrote the 4 options, none of them are correct.

remember, the area of a triangle is base times height divided by 2

A = (b × h) / 2

given the numbers in the problem statement

b = 5, h = 8

A = (5 × 8) / 2 = 40 / 2 = 20

you need to pick the answer option in your original document that would lead to 20.

none of the 4 options you gave me here would result in 20. so, there must be something wrong with them.

Answer:

G (-2, -3) is in the solution set

Step-by-step explanation:

Finding the solution set

You are given the boundary lines for the inequalities, but the graph does not show the solution set.

The line for inequality y < -2x -4 is the one with negative slope that extends from upper left to lower right. The relation of y to the comparison symbol is ...

y <

indicating that y-values in the solution set will be less than those on the line. The line itself is NOT included in the solution set. That is, "shading" will be below and left of the line.

The line for inequality 2x - 4y ≤ 8 is the one with positive slope. Considering the variable with the positive coefficient, its relation to the comparison symbol is ...

x ≤

indicating that x-values in the solution set will be less than (or equal to) those on the line. The line IS included in the solution set. Shading will be above and left of the line with positive slope.

Then the doubly-shaded area is the quadrant at the left side of the X where the lines cross. The lower boundary of that is included in the set, while the upper boundary is not.

Considering the points

Now that you know the location of the solution set, you can decide whether any given point is in it, or not.

Plotting the points, you find that F and G are on the boundary lines, and H and J are outside the solution set. Point F(-2, 0) is on the upper boundary line, so is not in the solution set, either.

The point listed in choice G, (-2, -3) is in the solution sets of both inequalities.
