If f(x) = 5-2x find f(9)+ 3

Answers

Answer 1
Answer:

f (9) = 5 - 2 (9)

f (9) = 5 - 18

f (9) = - 13

f (9) + 3 = - 13 + 3

f (9) + 3 = - 10
Answer 2

A watch was purchased for $25. The wholesale cost was $16. What percentage was the markup?64%
1.56%
56.25%
0.56%

Answers

If you would like to know what percentage was the markup, you can calculate this using the following steps:

x% of $16 is $25
x% * 16 = 25
x/100 * 16 = 25
x = 25 * 100 / 16
x = 156.25%

156.25% - 100% = 56.25%

The correct result would be 56.25%.

What is the slope of the line?

The slope of the Line is 3

What is the slope of a line?

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) may be easily determined by finding the difference among the coordinates of the points. The slope is normally represented by the letter 'm'.

Conclusion: The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

The general equation of a line having a slope is y = mx + c

we have to arrange the equation 6x - 2y = 10 in y = mx + c form

6x -2y = 10

2y = 6x - 10

y = 3x - 5

The slope of the line is represented by m, the value of m in equation y = 3x - 5 is 3

We need to rearrange the equation so that it is in slope-intercept form:

y = mx + b

Where m is the slope and b is the y-intercept.

To do this we just solve for y.

Subtract 6x from both sides.

-2y = 10 - 6x

Divide both sides by -2.

y = -5 + 3x

m=3

The line has a slope of 3.

Identify n in the equation below. Then name the property that is used.6 = 6 + n

A). 1, Identity property of addition

B). 0, Identity property of addition

C). 0, Commutative property of addition

D). 0, Multiplicative property of Zero

Answers

I believe it is B. A and D  you can cross them out. So you are left with B or C. The Identity Property is when you add any number to 0 then you will get the same number. So the answer is B. Hope all that made sense.
