What is the constant in the expression 8x-2y+48

Answer: 5

Step-by-step explanation:

From the question, Anna has an amount of $42.50 to pay for pizza and each pizza costs $8.50. She wants to buy an unknown number of pizzas, that we are representing by p.

P= Total amount Anna has/cost of each pizza

P = $42.50/$8.50

P = 5

Anna can buy 5 pizzas

Answer:

5

Step-by-step explanation:

Answer: There is 61.9% decrease in the value from 126 ounces to 48 ounces.

Step-by-step explanation:

Original value=126 ounces

New value = 48 ounces

Difference = 126-48 = 78 ounces

So, Percentage of decrease value is given by

So , there is  61.9% decrease in the value from 126 ounces to 48 ounces.

Answer:

Decrease in percentage = 61.9%

Step-by-step explanation:

Decrease from 126 ounces to 48 ounces percent

First find out the amount of decrease. Subtract the number to find the amount of decrease

now find out which percentage is 78

percentage =

Decrease in percentage = 61.9%

Final answer:

A t-chart representing the y = |5x| shows pairs of x and y values, where y is the absolute value of 5 times x. Whether x is negative or positive, y is always positive, demonstrating the dependence of y on x in the total value context.

Explanation:

The absolute value equation given is y = |5x|. A t-chart representing this equation would list several values of x against their corresponding y values, where y is the absolute value of 5 times x. For instance, for x = -1, y = |-5| = 5; for x = 0, y = |0| = 0; for x = 1, y = |5| = 5. Thus, the t-chart should show that, regardless of whether x is negative or positive, y is always positive, given the nature of absolute value.

Here's an example of what the t-chart could look like:

• (-1, 5)
• (0, 0)
• (1, 5)

The dependence of y on x in this scenario is such that y increases linearly as the absolute value of x increases.

Answer: Choice C

=============================================

Explanation:

Choices A, B and D are not true because of the negative y values. The result of an absolute value is never negative. So we can rule out choices A, B, and D. We have choice C as the only thing left, so this must be the answer.

-------------

Another way to see this is by plugging in each x value to see what y value comes out.

• If x = -2, then y = |5*x| = |5*(-2)| = |-10| = 10
• If x = -1, then y = |5*x| = |5*(-1)| = |-5| = 5
• If x = 0, then y = |5*x| = |5*0| = |0| = 0
• If x = 1, then y = |5*x| = |5*1| = |5| = 5
• If x = 2, then y = |5*x| = |5*2| = |10| = 10

The y outputs from top to bottom are: 10, 5, 0, 5, 10

This matches with what choice C shows.
