you sold 4/5 of the nature photographs at the silent auction. What portion. of the photographs were unsold?

1 answer:

3 0

First, we'll want to know what the total amount of pictures is.

The fraction '4/5' implies that the whole fraction would be '5/5'.

Using that, we get 5/5 - 4/5

5/5 - 4/5 = 1/5

Therefore, 1/5 of the photographs were not sold.

Which equation represents a linear function? A) y = |x| B) y = x2 C) y = -3x3 D) y = 1 4 x

Step2247 [10]

Linear means the highest exponent on the placholder is 1
it is also just a straight line

y=|x| is like y=(√x)², it is 2 straight lines

B. y=x², exponent is 2 so no

C. y=-3x³, exponent is 3, so no

D. y=1/4x, yep

D is the answer

Answer:

Is y = 4x - 7 a linear function?
Is y = 6x² - 1 a linear function?
Is y = $\frac{1}{2x}$ + 10 a linear function?

Step-by-step explanation:

Yes it is - when you graph this equation, it results in a [straight] line, signalling that it is a linear function.
No it's not - when you graph this equation, it results in a v- kinda shape on the graph. Linear functions are [straight] lines on a graph, and this line wasn't straight. In fact, this wasn't even a line.
No it's not - when you graph this equation, it results in a bend at the origin. The line on the graph is not straight, so this is not a linear equation.

For the graphs -

The first one represents the linear function [y = 4x - 7]

The second one (that looks like an L) represents the last not linear function [y = $\frac{1}{2x}$ + 10]

The third one (that looks like a V) represents the first not linear function [y = 6x² - 1]
