You have an initial amount of $55 in a savings account and you deposit an equal amount into your account each week. After 6 week
bonufazy [111]
Given:
initial deposit = 45
total deposit = 105
w = weekly deposit
x = no. of weeks = 5 weeks
y = amount in dollars
45 + 5w = 105
45 + 5w = 105
5w  = 105 - 45
5w =  60
w = 60/5
w = $12 weekly deposit.

y = $45 + $12x  
<span>x = (y - 45)/12

</span>To check:
y = 45 + 12(5)
y = 45 + 60
y = 105 total deposit in 5 weeks

x = (105-45)/12
x = 60/12
x = 5 weeks

I hope this help

4. I NEED HELP ASAP!! PLEASE PUT AND ANSWER AND STEP BY STEP EQUATION!! IF YOU DON'T KNOW THE ANSWER DON'T PUT ANYTHING!!
tino4ka555 [31]

Answer:

The answer is A (y = 2x - 2)

Step-by-step explanation:

B and D aren't correct because the y-intercept is a positive 2 instead of negative 2 like the graph shown. We're now left with A and C. Go on one point of the graph and count up or down to go on the same y value as the other point. Go left or right and count until you go to the same point. Remember that the slope equation is rise/run. Rise meaning up or down. Run meaning left or right.

HELP PLZ <br> i need help with this math side i just need b,c,d a =4x+2y=16
tino4ka555 [31]

Answer:

Please check the explanatio.

Step-by-step explanation:

Solving Part b)

We know that the slope-intercept form of the equation line is

y=mx+b

where m is the slope and b is the y-intercept

Given the equation

4x+2y=16

Re-writing the equation in the slope-intercept form

4x+2y=16

y=-2x+8

Here, m=-2 and b=8

Thus, the equation in the slope-intercept form will be:

y=-2x+8

Solving Part c)

As you sold two pounds of cheddar cheese.

i.e. y=2

substituting y=2 in the slope-intercept form of the line equation

y=-2x+8

2=-2x+8

Subtract 8 from both sides

-2x+8-8=2-8

-2x=-6

Divide both sides by -2

\frac{-2x}{-2}=\frac{-6}{-2}

x=3

You sold 3 pounds of swiss cheese.

Solving Part d)

y=-2x+8

putting x=2.5 in the equation

y=-2x+8

2=-2\left(2.5\right)+8

2=3

The sides are not equal

<em>FALSE</em>

Thus, x=2.5 does not make any sense in the context of the problem.
