Step-by-step explanation:

used a calculator (ti-84 plus tx instruments)

Answer:

1a) $11,610

1b) $967.5

2) 15.826

3) 20%

Step-by-step explanation:

1a)

27/100 = .27

.27(43,000) = $11,610 a year

1b) $11,610 / 12 months = $967.5 a month

2)

19.3/100 = .193

.193(82) = 15.826 hits

3) 16/80 = .2

.2(100) = 20%

I don't know what you are asking for 4 and 5.

It would happen because 5 is 5 4 is 4 3 is 3 2 is 2 1 is 1 and 0 is only one number 0.

If we fold a number line so that a vertical crease goes through 0, the points will match up for the same because of the same distance on both sides from zero.

A number line is a straight line representing numbers on it either vertically or horizontally.

If we fold a number line so that a vertical crease goes through 0, the points will match up for the same. this is due to the reason the points on a number line from zero are at the same distance on both sides so, the numbers will superimpose on each other when folded vertical through 0.

Since the distance of 1 and -1 is the same as zero so 1 would match -1.

Similarly for -2 and 2, -3 and 3, etc.

Answer: =−4m−8 1/2 (Decimal: -4m+\,{-17}/{2}\,)

Answer:

1. 2

2. 30

Step-by-step explanation:

1. The weird circle looking thing essentially means you're putting p(x) inside of q(x). This means you take the x in q(x) and replacing with the entire p(x)

so q(x) = -3x - 4

(q °p)(x) = -3 (-2x+4) -4  sorry I can't find the actual circle thing symbol

now distribute to get the simplified equation:

= 6x -12 -4

= 6x - 16

because you're doing (q - p )(3), you would plug 3 for x into the new equation

6(3) - 16 = 2

and thats you're answer for the first one

for the second one its the other way around, so you're putting all of q(x) into p(x)

take p(x) : -2x+4

and now replace the x with the entire q(x)

so (p - q)(x) = -2 (-3x-4) +4

simplify: = 6x+8+4 = 6x+12

so now since we're doing (p-q)(3), we need to plug in 3 for x in the new equation

= 6(3)+12 = 30

lmk if those were wrong or if my explanation was unclear, there's another way I can explain it even though its the same process :)

Answer:

y = -1/2x -7

Step-by-step explanation:

. The slope of the line (rise over run) goes down so it's negative and it you go down (bc it's negative slope) 1 and go over 2 so it would be -1/2

. B stands for the y intercept so it would be -7 because the line goes through -7 on the vertical line.
