Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality". Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Answer:

Now, we’re going to consider an example of proportional relationship in our everyday life: When we put gas in our car, there is a relationship between the number of gallons of fuel that we put in the tank and the amount of money we will have to pay. In other words, the more gas we put in, the more money we’ll pay.

$(2p+4)+5(p-1)-(p+7)\\ \\ 2p+4+5p-5-(p+7)\\ \\ 2p+4+5p-5-p-7\\ \\ (2p+5p-p)+4-5-7\\ \\ (7p-p)-1-7\\ \\ 6p-8=2(3p-4)$

That should be the final answer. If you need help with the distribution process I can explain that separately if needed. If not, hope this helps!

What is x to the power of 2 minus x?

pickupchik [31]

If you are asking what x to the power of 2 minus x is as a mathematical expression, then your answer is:

= x^2 - x

If you are asking what another equivalent expression for x^2 - x is or if you want it in factorised form, then your answer is:

= x ( x - 1 )

Can someone help with this question?

Mars2501 [29]

Answer:

y ≤ ¼x + 1

Step-by-step explanation:

Starting from the y-intercept of course, use rise\run until you hit another endpoint [finding the rate of change (slope)]. That means me we go up north one block, then go over four blocks east, and since the slope is already simplified, we do not need to go any further. Now all we have left is to determine the correct inequality symbol, and since we know that the bottom portion of the graph is shared, we automatically know it is less than, but to check this, we need to do what is called a zero-interval test [do not recall the actual term], meaning that we plug in 0 for both y and x, getting 0 < 1, which is a GENUINE statement, so the bottom portion stays shaded, otherwise we would have had to shade the top portion if it were a false statement. Finally, we have to determine if we have to add an equivalence line under the inequality symbol, and we DO because as you can see, the line is SOLID BLACK. If it were DASHED BLACK, then it would stay "<" instead of "≤".

I am joyous to assist you anytime.
