Determine the equation of a line that passrs through the point (4,-1) and also parallel to y=3x+4

nexus9112 [7]

First, plug in the given point into y=mx +b to find b (the y-intercept of the line). Use the same slope (m) in the equation since parallel lines have the same slope (3 in this case).

-1 = 3(4) +b
-1 = 12 + b Subtract 12 to both sides.
-13 = b

Now, put your m and b into y=mx+b.

The final answer/equation of your line is:

y=3x -13

A book with a base price of $15.75 is marked up by 65%. What is the new price, to the nearest cent?

Vaselesa [24]

15,75 - 100 %

100 % = 100/100 = 1

Then every number multiplied by 1 is 100 % of itself.

If the book was marked up 65% of what is was before, it makes a price of 165% when compared to the original.

165% = 165/ 100 = 1,65

15,75 . 1,65 = 25,9875

25,99 is the nearest option.

Ramona is a saleswoman whose base plus commissions amounted to $52,561 last year. If her base pay was $23,960 and she made $77,3

Ksju [112]

Answer:

37%

Step-by-step explanation:

If Ramona received an overall pay of $52,561 last year, $23,960 of which was base pay, we can first subtract these two numbers to find the amount she made from her sales commission:

$52,561 - $23,960 = $28,601

In order to find her percent commission, we can set up a proportion:

$\frac{p}{100}=\frac{28,601}{77,300}$ , where 'p' is her rate of commission
