Answer:

Part a) The graph in the attached figure (see the explanation)

Part b) The friend is not correct

Step-by-step explanation:

<u><em>The questions are</em></u>

a. Write and graph a system of linear equations that represent the amounts in each of your savings accounts

b. Your friend says that in 10 weeks you will both have the same amount of money in your savings accounts. Is your friend correct? Use the graph from part (a) to explain your answer.

Part a)

Let

x ----> the number of weeks

y ---> the amount in the saving account

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

In this problem we have

<em>Your saving accounts</em>

The slope is equal to $m=\$10\ each\ week$

The y-intercept is equal to $b=\$90$

substitute

$y=10x+90$ ----> equation A

<em>Your friend saving accounts</em>

The slope is equal to $m=\$15\ each\ week$

The y-intercept is equal to $b=\$35$

substitute

$y=15x+35$ ----> equation B

using a graphing tool

the graph in the attached figure

Part b) Your friend says that in 10 weeks you will both have the same amount of money in your savings accounts. Is your friend correct? Use the graph from part (a) to explain your answer

we know that

When solving a system of equations by graphing, the solution of the system is the intersection point both graphs

In this problem, the intersection point is (11,200)

That means ----> In 11 weeks, both you and your friend have the same amount of money saved up, $200

Therefore

The friend is not correct

Write the standard form equation of the line through the given points. through (0.-4) and (-3,-2)

Alexxx [7]

Answer:

The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is $\frac{2}{3}x+y=-4$

Step-by-step explanation:

The standard form of equation is $Ax+By=C$

Finding slope

Using the given points (0,-4) and (-3,-2) we can find slope using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

$Slope=\frac{-2-(-4)}{-3-(0)}\\Slope=\frac{-2+4}{-3} \\Slope=-\frac{2}{3}$

Finding y-intercept

Using point (0,4) and Slope=-2/3 we can find y-intercept

$y=mx+b\\-4=-\frac{2}{3}(0)+b\\-4=0+b\\b=-4$

The slope intercept form of the line through the given points. through (0.-4) and (-3,-2) having slope =-2/3 and b=-4 will be:

$y=mx+b\\y=-\frac{2}{3}x-4$

Now, standard form of equation will be: $\frac{2}{3}x+y=-4$

So, The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is $\frac{2}{3}x+y=-4$
