1. 29. Solve for the variable and graph the solution on a number line: –2x < –10 30. Solve for the variable and graph the solution on a number line: 9 + c > –2 31. Solve for the variable and graph the solution

2. v – 4 ≥ 3 (6 + 2v

3. The last term, "the constant", is -5 Step-1 : Multiply the coefficient of the first term by the constant 4 • -5 = -20 Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is -8

4.The first term is, 4p 2 its coefficient is 4 . The middle term is, -8p its coefficient is -8 . The last term, "the constant", is -5 Step-1 : Multiply the coefficient of the first term by the constant 4 • -5 = -20

Step-by-step explanation:

the rest is up to you, and u better say thanks and give me brainliest this took ages to explain

Prove if a and b are integers, prove that if a is even and b is even then a+b is even

jeka57 [31]

Answer:

Let a and b integers and suppose that are even numbers. Then, exist integers k and m such that $a=2k$ and $b=2m$ .

Then,

$a+b=2k+2m=2(k+m)=2n$

Since, k and m are integers then n=k+m is an integer. Then, since a + b is of the form 2 by an integer n, then a + b is an even number.

2nd Option: x + y = -1

General Formulas and Concepts:

Left to Right

Algebra I/Geometry

Plug 'n' Chug
Graphing and Eyeballing

Step-by-step explanation:

Since Point A is included in the altitude, we must have an equation that has to make Point A a solution set in the equation.

Pluging in and chugging Point A into each equation should tell us what the equation should be.

Option 1

x - y = 1

-3 - 2 = 1

-5 ≠ 1

We see here that -5 does not equal to 1. Therefore option 1 is incorrect.

Option 2

x + y = -1

-3 + 2 = -1

-1 = -1

We see here that -1 does equal to -1. Therefore option 2 is correct.

Option 3

x + y = 1

-3 + 2 = 1

-1 ≠ 1

We see here that -1 does not equal to 1. Therefore option 3 is incorrect.

Option 4

x - y = -1

-3 - 2 = -1

-5 ≠ -1

We see here that -5 does not equal to 1. Therefore option 4 is incorrect.

We can also graph the points and eyeball it. Doing so, we should see that our y-intercept is around -1 and our slope is also negative. Option 2 would be the best fit.
