Which equation does not represent a direct variation? Explain.

Answers

Answer 1

Answer:

y = 3x + 2

Step-by-step explanation:

"When x is zero in a direct variation equation y will also be zero. ... Equations of the form y = kx + b where b is a number other than zero are not direct variation equations because when x is zero in any of these y is not zero. Normally direct variation equations are written as y = k•x or just y = kx."

in short, y = 3x + 2 can't be turned into y = kx

you could also immediately tell it's y = 3x + 2 because it includes + 2

What polygon has interior angle measures of 162°?

Answers

Answer:

If you are given the measure of each interior angle (162 degrees) of a regular polygon. how many sides does the polygon have? If you look at a pentagon first where the interior angle is 108 deg then you see. The angle at the center is 180-162=18 deg and 360/18=20 so the polygon has 20 sides.

Carissa earns $450 per week for a 40 hour work week plus $16.83 per hour for each hour of overtime after 40 hours. Write an equation that would be used to determine her weekly wages where, W, is her wages and, V, is the number of overtime hours worked.

Answers

Answer:

The equation that determines Carissa's weekly wages is W = 450 + 16.83 × V

Step-by-step explanation:

The given parameters are

The amount Carissa earns per week = $450

The amount Carissa earns for each overtime hour = $16.83

Where the given variables are;

W = Her weekly wages

V = The number of overtime hours worked

Therefore, the equation that would be used to determine her weekly wages is given as follows;

W = 450 + 16.83 × V.

dollars. Which situation can be represented by this
5x < 3x + 2
A The cost of 5 notebooks is greater than the cost of 3 notebooks plus a $2 pen.
B The cost of 5 notebooks is less than the cost of 3 notebooks with a $2-off coupon,
C The cost of 5 notebooks is less than the cost of 3 notebooks plus a $2 pen.
D The cost of 5 notebooks is $2 greater than the price of 3 notebooks.

Answers

Answer:

The answer is C.

Step-by-step explanation:

The < sign means that it will be less than so you can remove A and D. But it's not B either because of the $2 off coupon. Off means you would be subtracting meaning it'll look like this 5x < 3x - $2. So the correct answer is C.

Hope this helps!

x = 2/3

Step-by-step explanation:

cross multiply

-9(x-4) = 10(3x+1)

and then solve the equation

-9x + 36 = 30x + 10

36 = 39x + 10

26 = 39x

x = 2/3

Cross multiply
-9(x-4) = 10(3x + 1)
-9x + 36 = 30x + 10
-9x = 30x - 26
-39x = -26
X = -26/-39 = 2/3
The solution is x = 2/3
