<h3>Answer:</h3>

graph of a parabola symmetric about the x axis with x intercept at negative 5

<h3>Explanation:</h3>

A parabola that opens horizontally does not pass the vertical line test. You can draw a verticla line that intersects the curve in 2 places. A function must be single-valued, so can only have one y-value for any x-value.

A printer takes 30 minutes to print a banner and a poster. I will take 50 minutes to print a banner and three posters. How long

qwelly [4]

Answer:

It takes the printer 20 minutes to print a banner

Step-by-step explanation:

Notice that there are two unknowns in this problem: the time to print a poster and the time to print a banner. Let's assign the letter "b" to the time it takes to print a banner, and "p' the time it takes to print a poster.

So we can write the following two equations involving the total amount of time that takes to print in the two cases:

$b+p=30\\b+3p=50$

We can solve for the unknown "p" by subtracting term by term in the equation set above:

$b+3p=50\\b+p=30\\\\b-b+3p-p=50-30\\2p=20\\p=10$

So it takes 10 minutes to print each poster, we can find the time it takes to print the banner by using the value we just found in one of the equations:

$b+p=30\\b+10=30\\b=20$

So, it takes 20 minutes to print a banner.

11 4/5 divided by 3 1/5 estimation

pychu [463]

The required estimation of 11 4/5 divided by 3 1/5 is 4.61.

Given that,
To determine the estimation of 11 4/5 divided by 3 1/5.

<h3>What is arithmetic?</h3>

In mathematics, it deals with numbers of operations according to the statements.

In the given question we have given, 2 mixed fractions we have to determine the simplified fraction by dividing one from the other, as stated in the question.

Simplification,

11 + 4 / 5 = 59 / 4
3 + 1 / 5 = 16 / 5

11 4/5 divided by 3 1/5 estimation,
= ( 59/4 ) / (16 / 5)
= 59 * 5 / 4 * 16
= 4.61

Thus, the required estimation of 11 4/5 divided by 3 1/5 is 4.61.
