Write the equation of the line passing through the points (-7,9) and (7,5).
inn [45]

Answer:

y=-\frac{2}{7} x+7

Step-by-step explanation:

First Solve For The Slope Using The Two Given Points!

M = Slope

M = \frac{y2-y1}{x2-x1}

M = \frac{5-9}{7--7}           Two negative signs together makes addition!

M = \frac{-4}{14}               Move the negative sign (only if the fraction has a negative)

M = -\frac{4}{14}            Simplify

M = -\frac{2}{7}              Final Answer

Then see how many units the graph goes up = y-intercept

If $5000 is invested at a rate of 3% interest
harkovskaia [24]

The value of the investment in 5 years is $5805.9

<h3>What is Interest ?</h3>

Interest is the amount earned over years for the amount invested.

It is given that

Principal = $5000

Rate = 3%

Compounded Quarterly

Time = 5 years

Amount = ?

The Amount is given by the formula

Amount = P( 1 + (r/n))ⁿˣ

Here n = t = time period for which the investment has been done.

Amount = 5000( 1+(3/4 * 100)⁴ˣ⁵

Amount = 5000 (1.16)

Amount = $ 5805.9

Therefore , The value of the investment in 5 years is $5805.9

Answer:

0.5x+20=0.25x+30, m=40

Step-by-step explanation:

Blue: y=0.5x+20

Red: y=0.25+30

We’re looking for where the y (cost) is equal, so we can set the two equations to each other:

Isolate x:

0.5x+20=0.25x+30

0.5x+20-20=0.25x+30-20

0.5x=0.25x+10

0.5x-0.25x=0.25x+10-0.25x

0.25x=10

x=40

m= 40
