What is an equation of the line that passes through the points (-6, -7) and (6, 3)?
Mademuasel [1]

Answer:

y+7=5/6(x+6)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(3-(-7))/(6-(-6))

m=(3+7)/(6+6)

m=10/12

m=5/6

y-(-7)=5/6(x-(-6))

y+7=5/6(x+6)

Andrew receives $480 per day for working on a project. David receives $22 per hour for working on the same project. Who gets a b
DochEvi [55]
How many hours are they working?

I would say andrew receives the better salary bc if we multiply David's hourly rate by 8 (the typical work day), you will see. Slow that $176 is way below $480 which is what Andrew received per day. Based on a 8 hr day.
$22x8 = $176

Which choice is equivalent to the expression below? 5√10+√40+√90 <br><br> the answer was 10√10
DaniilM [7]

Answer:

5\sqrt{10}+\sqrt{40} +\sqrt{90}=10\sqrt{10}

Step-by-step explanation:

We have the following expression:

5\sqrt{10}+\sqrt{40} +\sqrt{90}

Remember the property of root multiplication:

\sqrt[n]{x*y}=\sqrt[n]{x}\sqrt[n]{y}

Therefore:

\sqrt{40}=\sqrt{4*10}=\sqrt{4}*\sqrt{10}=2\sqrt{10}

Also:

\sqrt{90}=\sqrt{9*10}=\sqrt{9}*\sqrt{10}=3\sqrt{10}

Then we have that:

5\sqrt{10}+\sqrt{40} +\sqrt{90}=5\sqrt{10}+2\sqrt{10}+3\sqrt{10}

Remember the property of sum of roots:

a\sqrt{b}+2a\sqrt{b}=3a\sqrt{b}

Finally:

5\sqrt{10}+\sqrt{40} +\sqrt{90}=(5+2+3)\sqrt{10}

5\sqrt{10}+\sqrt{40} +\sqrt{90}=10\sqrt{10}
