Answer:
For the first one, it is 12. For the second one im not too sure but I would guess that it is 9.20.

Using a system of equations, it is found that a small box of tangerines costs $10 and a large box costs $14.
<h3>What is a system of equations?</h3>
- A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the <em>variables </em>are:
- Variable x: Cost of a small box.
- Variable y: Cost of a large box.
Krystal sold 7 small boxes of tangerines and 14 large boxes of tangerines for a total of $266, hence:

Simplifying by 7:


Mary sold 14 small boxes of tangerines and 3 large boxes of tangerines for a total of $182, hence:

Since
:




Then

A small box of tangerines costs $10 and a large box costs $14.

Answer:
A. y = -8x -5
Step-by-step explanation:
You will notice that when x increases from 2 to 5, y decreases from -21 to a number that is more negative. Thus only the first two answer choices are possibilities, since the others have a positive coefficient for x.
Trying the first given point in the first answer choice, we see that it works:
-21 = -8·2 -5
so, that is the equation we're looking for.
y = -8x -5
Answer:
Understand the question and solve it
Step-by-step explanation:
Using the slope and 1 point format: (y- y₁) = m(x - x₁)
where m = slope = 5, and point is (x₁, y₁). In this case point (x₁, y₁) = <span>(-2, -1)
</span><span>x₁ = -2, y₁ = -1
</span>
Using: (y- y₁)<span> = m(x </span><span>- x₁)
</span>
y - -1 = 5(x - -2)
y + 1 = 5(x + 2).
We can go further but since our options are in that format above, we stop there.
So answer is option B.
