If the value of "y" varies directly with "x"
and y = -8 when x = 4.
Find "y" when x = -4.
Answer:
-16
Step-by-step explanation:
because y varies directly with 4 when you remove 8 from 4 you get -4 and when you remove it from -8 you get -16
The value of y is 8 for the given condition.
What is linear equation?Linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. Generally, the equation is of the form Ax+B=0.
For the given situation,
The value of "y" varies directly with "x" and y = -8 when x = 4.
First we need to form the equation for this condition as [tex]y=kx[/tex].
Here, x=4 and y=-8
⇒ [tex]-8=k(4)[/tex]
⇒ [tex]k=-2[/tex]
Now substitute the value of k and x=-4 in the above equation to get the value of y,
⇒ [tex]y=kx[/tex]
⇒ [tex]y=(-2)(-4)[/tex]
⇒ [tex]y=8[/tex]
Hence we can conclude that the value of y is 8 for the given condition.

Step-by-step explanation:
She sells her bike for 104 dollars
She sells toys for 68 dollars
Total 172
The question is a bit ambiguous. There are 4 divisions. So I would assume that you need to divide 172 by 4. If you do that you get 43
I think that what they are getting at is the answer is C. There are 4 months shown. And 1 month would be 43 dollars. She has enough for 3 more months.

A study of 800 homeowners in a certain area showed that the average value of the homes was $82,000, and the standard deviation was $5000. How many of these homes have a value greater than $83,500.
Round to a whole number.
I got 62 it says that is wrong answer.
Answer:
400
Step-by-step explanation:
it says average which probably means 400
33.36% of these homes have a value greater than $83,500.
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x \ is\ raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]
Given that μ = $82000, σ = $5000.
For x > 83500:
[tex]z=\frac{83500-82000}{5000} =0.43[/tex]
From the normal distribution table, P(x > 83500) = P(z > 0.43) = 1 - P(z < 0.43) = 1 - 0.6664 = 33.36%
33.36% of these homes have a value greater than $83,500.

A bookshelf sits on top of a large desk. Together, their height is 6.75 feet. The difference between their heights is 1.85 feet. How tall is the bookshelf?? Let the height of the bookshelf = x and the height of the desk = y.
Answer: 4.9
Step-by-step explanation:
The height of the bookshelf is 4.3 feet and the height of the desk is 2.45 feet.
What is the system of equations?Simultaneous equations are any one or more equations that can have the same number of unknowns and be solved concurrently. The system of equations is a simultaneous equation.
Given:
A bookshelf sits on top of a large desk.
Together, their height is 6.75 feet.
The difference between their heights is 1.85 feet.
Let the height of the bookshelf = x and the height of the desk = y.
x + y = 6.75 {equation 1}
x - y = 1.85 {equation 2}
Add both equations,
we get,
2x = 6.75 + 1.85
2x = 8.6
x = 4.3
And from equation 2,
y = 2.45
Therefore, the solution is x =4.3 and y = 2.45.
