ANSWER X=4. You basically plug what y equals to into the second equation the solve for x.

Ivanshal [37]3 years ago

Answer:

x = 4

y = -7 or (-7, 4)

Step-by-step explanation:

y = -2x + 1

4x + y = 9 replace y in the second equation with (-2x + 1) since y is equal to it

4x + (-2x + 1) = 9 add like terms

2x + 1 = 9 subtract 1 from both sides

2x = 8 divide both sides by 2

x = 4 since y = -2x + 1 replace x with the value we found

y = (-2) × 4 + 1 = -7

Solve the equation. Check your solutions.<br> |4b+4|=|2b+8|
anzhelika [568]

Answer:

<h2><u>b = 2 or b = -2</u></h2>

Explanation:

|4b + 4| = |2b + 8|

<em>Solve absolute value</em>

|4b + 4| = |2b + 8|

Either 4b + 4 = 2b + 8 or 4b + 4 = −(2b + 8)

4b + 4 = 2b + 8 <em>(Possibility 1)</em>

4b + 4 − 2b = 2b + 8 − 2b <em>(Subtract 2b from both sides)</em>

2b + 4 = 8

2b + 4 − 4 = 8 − 4 <em>(Subtract 4 from both sides)</em>

2b = 4

2b / 2 = 4 / 2 <em>(Divide both sides by 2)</em>

b = 2

4b + 4 = −(2b + 8) <em>(Possibility 2)</em>

4b + 4 = −2b − 8 <em>(Simplify both sides of the equation)</em>

4b + 4 + 2b = −2b − 8 + 2b <em>(Add 2b to both sides)</em>

6b + 4 = −8

6b + 4 − 4 = −8 − 4 <em>(Subtract 4 from both sides)</em>

6b = −12

6b / 6 = -12 / 6 <em>(Divide both sides by 6)</em>

b = -2

<h2><u>b = 2 or b = -2</u></h2>

fgiga [73]

One million: 10^6

Ten million:  10^7

So the exponent will be anywhere between 6 and 7, inclusive
