X+y=155. Y= -x+155

1.50x +4(-x+155)= 520
1.50x-4x+620=520
-2.5x =-100
X= 40. Y=110

I need help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Zina [86]

Answer:

Yes, x and y have a proportional relationship.  

Step-by-step explanation:

A proportional relationship means that, when comparing two quanities, that they are both changing at a constant (same) amount.  When looking at a table to compare quantities, you can see that the pounds of tomatoes 'x' is increasing by one (1) each time.  If you look at the amount spent in dollars 'y', you can see that for each pound (x), the cost is increasing by $4.  So, since for every pound of tomatoes that is purchased increases by $4, then their relationship is proportional.

Given f(x)=9-2x, find f(10).<br><br> A.-11<br> B.11<br> C.29<br> D.-29
zaharov [31]

The given function is a linear function that decreases as the value of the

input <em>x</em> increases.

  • The value of f(10), given f(x) = 9 - 2·x is option <u>A. -11</u>

Reasons:

The given function is f(x) = 9 - 2·x

The output of the function is the value of f(x) for a given input <em>x</em> of the function.

The input value, <em>x</em> is substituted into the function to obtain the output value, f(x).

Given that the input, x = 10

We have;

f(10) = 9 - 2×10 = -11

Therefore, the correct option for f(10) is <u>A. -11</u>

Maddie has a gross monthly income of $2200. She has 35% of her paycheck withheld as deductions.
Softa [21]

Answer:

The percent of net income Maddie gives as rent = 29.97%

Step-by-step explanation:

Given:

Gross monthly income for Maddie = $2200

Percentage of her paycheck withheld = 35%

Amount paid for rent = $400

To find the percent of her net monthly pay that goes to rent.

Solution:

Amount of paycheck withheld as deductions :

⇒ 35% of the gross income

⇒ 35% of $2200

⇒ 0.35\times $2200

⇒ $ 770

Net income = <em>Gross income - deductions</em><em> = </em>\$2200-\$770 = $1430

Percentage of net income given as rent is given as :

⇒ \frac{Amount\ given\ as\ rent}{Net\ income}\times 100

⇒ \frac{400}{1430}\times 100

⇒ 27.97%   (Answer)
