Simplify 5(R + 2) - 6. 5R + 4 5R - 4 5R - 6

Mathematics
1 answer:
Scorpion4ik [409]3 years ago
3 0

Step-by-step explanation:

Hey, there!!

5(R+2)-6.

Fistly multiply (R+2) by 5.

=5R + 10 - 6

Subtract 6 from 10.

= 5R +4.

Therefore, 5R + 4 is correct answer.

{ While simplifying the expression if there is multiplication or divide do it first and then add or or subtract like terms to get the simplified form of the expressions. }

<em><u>Hope</u></em><em><u> </u></em><em><u>it helps</u></em><em><u>.</u></em><em><u>.</u></em>

Fine the exact distance between the line 6x-y=-3 and the point (6,2). Show your work. Explain your answer.
AVprozaik [17]

Answer:

\sqrt{37} units

Step-by-step explanation:

If we draw a perpendicular from point (6,2) on the line 6x - y = - 3, then we have to find the length of the perpendicular.  

We know the formula of length of perpendicular from a point (x_{1}, y_{1} ) to the straight line ax + by + c = 0 is given by  

\frac{|ax_{1} + by_{1} +c |}{\sqrt{a^{2}+b^{2}}}

Therefore, in our case the perpendicular distance is  

\frac{|6(6)-2+3|}{\sqrt{6^{2} +(-1)^{2} } } = \frac{37}{\sqrt{37} } = \sqrt{37}  units. (Answer)

Amanda exercised for 10 minutes every day in the first week, 20 minutes in the second week, 30 minutes in the third week, and 40
Misha Larkins [42]
                  Amanda           Billy
1st week       10                   5
2nd week      20                  10 
3rd week       30                  20
4th week       40                  40
<span>
A) Amanda's method is linear because the number of minutes increased by an equal number every week.</span>
common difference is 10.
1st week      0 + 10 = 10
2nd week   10 + 10 = 20
3rd week    20 + 10 = 30
4th week    30 + 10 = 40

Billy's method is exponential:
5(2)^x

1st week   5(2⁰) = 5(1) = 5
2nd week  5(2¹) = 5(2) = 10
3rd week   5(2²) = 5(4) = 20
4th week   5(2³) = 5(8) = 40

When P it was $55 how many units well the profit maximizing firm supply to the market a 30 be 40 C 50 D 16
topjm [15]

Answer:

C. 50

Step-by-step explanation:

Here we have to look at the given graph and find the answer.

The vertical axis represents the price and cost per unit. That is represented by P.

The horizontal axis represents the units of output, that is represented by q.

We need to find the number of units when p = $55.

By look at the graph of the curve MC, when P = $55, the number of units is 50.

Therefore, the answer is C. 50.

Hope this will helpful to understand the concept.

Thank you.
