Answer:
original slope is 1
parallel slope is 1
Step-by-step explanation:
the slopes of parallel lines are equal
original line rise1/run1, slope is 1
parallel line rise2/run2, slope 2/2=1
Answer:
Step-by-step explanation:
We can use this expression to change the base of a logarithm from b to d.

Hey there!
<u>Solve </u><u>the </u><u>equation</u><u>:</u>
x = -10 ✅
2(x + 3) = x - 4
<em><u>Distributive property:</u></em> A(B + C) = AB + AC
<em>></em><em>></em><em> </em><em>Substitute </em><em>2</em><em> </em><em>for</em><em> </em><em>A</em><em> , </em><em>x</em><em> </em><em>for </em><em>B</em><em> </em><em>and </em><em>3</em><em> </em><em>for</em><em> </em><em>C</em><em> : </em>
2(x) + 2(3) = x - 4
2x + 6 = x - 4
<em>></em><em>></em><em> </em><em>Subtract </em><em>6</em><em> </em><em>from </em><em>each </em><em>side </em><em>:</em>
2x + 6 - 6 = x - 4 - 6
2x = x - 10
<em>></em><em>></em><em> </em><em>Subtract </em><em>x </em><em>from </em><em>both </em><em>sides </em><em>:</em>
2x - x = x - 10 - x
x = -10
▪️Let's check our work :
2(-10 + 3) ⇔ 2(-7) ⇔ -14
-10 - 4 ⇔-14
Therefore, your answer is x = -10
