M is the midpoint of PQ. MQ=5x+8 and PQ = 6x+56, find PM

Answers

Answer:

PM = 58

Step-by-step explanation:

The question tells us that the full line has a value of 6x+56. The midpoint divides this line into equal pieces. We are also given the value of half (MQ) of the line (5x+8). By subtracting 5x+8 from 6x+56, we can figure out the value of the other half of the line (PM).

This gives us the expression for PM: x+48

Now, since these are both the two parts of the midpoint, by definition, we know they're equal.

You equal both equations and get x=10

You plug in 10 as x in the expression we got for PM (10+48), which gives us the value 58.

Which fraction is close to zero?
a. 5/12 b. 8/12 c. 2/12 d. 4/6

Answers

Answer:

2/12

Step-by-step explanation:

Answer:

C) 2/12

Step-by-step explanation:

You need to convert the fractions to decimals (by dividing the top number by the bottom number).

5/12 = 0.416...

8/12 = 0.666...

2/12 = 0.166...

4/6 = 0.666...

As you can see, 2/12 in decimal form is closer to 0 than the other fractions.

Write the equation of a line that passes the point (-6,9)and is perpendicular to a line that passes through the points (-2,1) and (6,7).

Answers

Answer:  y = -(4/3)x + 1

Step-by-step explanation:

Let's start with finding an equation of a straight line (y=mx+b) that goes through points (-2,1) and (6,7).

The slope of a line, m, is the change in y for the change in x, or Rise/Run.

This is derived from the two points.

Rise (7-1) = 6

Run (6 - (-2)) = 8

Rise/Run = 6/8 or 3/4

The line is therefore y = (3/4)x + b

Find b by using one of the two points.  I'll use (-2,1), but the other would also work.

y = (3/4)x + b

1 = (3/4)(-2) + b

1 = -(6/4) + b

b = 10/4

The line becomes y = (3/4)x + 10/4

--------

A line perpendicular to this will have a slope that is the negative inverse of the original line.  The negative inverse of (3/4) is -(4/3).

The perpendicular line will be:

y = -(4/3)x + b

Use point (-6,9) to find b:

y = -(4/3)x + b

9 = -(4/3)*(-6) + b

9 = (24/3) + b

b = (27/3 - 24/3) = 3/3 = 1

The line is y = -(4/3)x + 1

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Let x represent the number of​ 30-day periods until the value of the gift cards will be equal.

Tavon has a gift card for $90 that loses $4 for each​ 30-day period it is not used. This means that x 30-day periods, the amount left would be

90 - 4x

He has another gift card for $ 80 that loses $3.50 for each​ 30-day period it is not used. This means that x 30-day periods, the amount left would be

80 - 3.5x

For the amounts left on each card to be the same, the number of periods would be

90 - 4x = 80 - 3.5x

90 - 80 = - 3.5x + 4x

10 = 0.5x

x = 10/0.5

x = 20

The value of each card when they have equal​ value is

90 - 4 × 20 = 90 - 80

= $10

Therefore, It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal​ value is $10
