-2x-11 because you distribute the negative to everything in the parentheses and then combine like terms
Step-by-step explanation:
7*3y - 7*5 + 2*4y + 12
= 21y - 35 + 8y + 6
= 29y - 29
= 29(y-1)
Answer:
(-2, 0)

<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x - 2y = 2
4x - 2y = -8
<u>Step 2: Rewrite Systems</u>
-x - 2y = 2
- Multiply both sides by -1: x + 2y = -2
<u>Step 3: Redefine Systems</u>
x + 2y = -2
4x - 2y = -8
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 5x = -10
- Divide 5 on both sides: x = -2
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation: 4x - 2y = -8
- Substitute in <em>x</em>: 4(-2) - 2y = -8
- Multiply: -8 - 2y = -8
- Isolate <em>y</em> term: -2y = 0
- Isolate <em>y</em>: y = 0
Hi, what’s your question?
4 out of 32 or 4/32 are infested with beetles, you know because it shows what beetles look like and it shows 4 trees infected with beetles out of the possible 32 trees
