Plug in the first x value into equation to solve for y. So (-8+2) is 6 and 6 squared is 36 so first coordinate point is (-8,36) just do that for each x value.

Ma poate ajuta cineva la acesta problema: pe o drepta g considerati punctele D, R,P si T coliniare in aceasta ordine astfel inca

valina [46]

Answer:

Givens

$DR=PT=3cm$ and $RP=4cm$

Points D, R, P and T are collinear.

The image attached shows a representation of this problem.

By sum of segments, we have

$DT=DR+RP+PT$

Replacing all given values, we have

$DT=3+4+3=10 \ cm$

Therefore, the segment DT is 10 centimeters long.

Now, we know that point E is the center of segment RP, which means is a middle point, divides the segment equally. So, to prove that segment DT is symmetrical regarding point E, we need to prove that both sides are equal.

$RE=EP=2cm$ , by definition of middle point.

By sum of segments, we have

$DR+RE=3+2=5cm\\EP+PT=5cm$

Which means $DR+RE=\frac{DT}{2}\\ EP+PT=\frac{DT}{2}$ .

Therefore, segment DT is symmetrical regarding point E.

The manager of a furniture factory finds that it costs $2200 to manufacture 100 chairs in one day and $4800 to produce 300 chair

EastWind [94]

Answer:

Step-by-step explanation:

If the relationship between cost and the number of chairs produced is linear, we would write an equation that expresses this relationship in the slope intercept form. It is expressed as

y = mx + c

Where

m represents the slope

c = intercept.

Slope = (y2 - y1)/(x2 - 1)

y2 = final value of y = 4800

y1 = initial value of y = 2200

x2 = final value of x = 300

x1 = initial value of x = 100

Slope, m = (4800 - 2200)/(300 - 100) = 2600/200 = $13 per chair.

To determine the intercept, we will substitute y = 4800, x = 300 and m = 13 into y = mx + c. It becomes

4800 = 13×300 + c = 3900

c = 4800 - 3900 = 900

The equation becomes

y = 13x + 900

The average test score of RSM students in September increased by 10%. In October it increased by another 15%. By what percent di

Aneli [31]

The Average test score start = 100%

It increases by 10%:

100% = 1
10% = 0.10

1 x 0.10 = 0.1
1 + 0.1 = 1.1

It increases by another 15%

1.1 x 0.15 = 0.165
1.1 + 0.165 = 1.265
Remember to move the place value digit to the right two spaces to make it a percentage

126.5% increase is your answer
