Answer:
y = 2x - 3
Step-by-step explanation:
x + 2y = 4
2y = -x + 4
y = -1/2x + 2

1 = 4 + b
-3 = b
y = 2x - 3

Answer:
<h3>D. {-3, and -2.5}</h3>
Step-by-step explanation:
Using the quadratic equation, you can find the solution to 2x2+15=-11x.
<u>First, you have to add by 11x from both sides.</u>
<u>Solve.</u>
2x²+11x+15=0
Use the quadratic formula.
<u>Quadratic formula:</u>
<u>Solve.</u>
Use the order of operations.
<u>PEMDAS</u>
- <u>Parentheses</u>
- <u>Exponents</u>
- <u>Multiply</u>
- <u>Divide</u>
- <u>Add</u>
- <u>Subtract</u>
<u>Multiply the numbers from left to right.</u>
4*2*15=120
<u>Do exponents.</u>
11²=11*11=121
<u>Subtract the numbers from left to right.</u>
121-120=1
<u>Solve.</u>
<u>Divide is another options.</u>
-5/2=-2.5
<u>Solve.</u>
<u>Solutions:</u>
- <u>Therefore, the correct answer is "D. {-3, -2.5}".</u>
