Answer:

<h3> the third one</h3>

Step-by-step explanation:

$\dfrac{5x+2}x=\dfrac{-12}{x-1}\\\\{}\quad\ \cdot x\qquad\ \cdot x\\\\5x+2\ =\ \dfrac{-12x}{x-1}\\\\\cdot (x-1)\quad \cdot (x-1)\\\\(5x+2)(x-1)=-12x$

Answer: C

Step-by-step explanation:

This is the answer because you have to multiply (x-1) on both sides and that will cancel out the denominator on the right. Then, multiply by x on both sides and that will cancel the denominator on the left side. When you do this, C should be your answer. Hope this helps :)

Which systems of equations intersect at point A in this graph?

abruzzese [7]

Answer:

The point of intersection of the system of equations is:

(x, y) = (-2, 1)

The correct system of equations intersect at point A in this graph will be:

$\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}$

Thus, the second option is correct.

Step-by-step explanation:

Given the point

A (-2, 1)

Let us check the system of equations to determine whether it intersect at point A in this graph.

Given the system of equations

$\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}$

Arrange equation variable for elimination

$\begin{bmatrix}y-4x=9\\ y+3x=-5\end{bmatrix}$

$y+3x=-5$

$-$

$\underline{y-4x=9}$

$7x=-14$

so the system of equations becomes

$\begin{bmatrix}y-4x=9\\ 7x=-14\end{bmatrix}$

Solve 7x = -14 for x

$7x=-14$

Divide both sides by 7

$\frac{7x}{7}=\frac{-14}{7}$

Simplify

$x = -2$

For y - 4x = 9 plug in x = 2

$y-4\left(-2\right)=9$

$y+4\cdot \:2=9$

$y+8=9$

Subtract 8 from both sides

$y+8-8=9-8$

Simplify

y = 1

Thus, the solution to the system of equations is:

(x, y) = (-2, 1)

From the attached graph, it is also clear that the system of equations intersects at point x = -2, and y = 1.

In other words, the point of intersection of the system of equations is:

(x, y) = (-2, 1)

Therefore, the correct system of equations intersect at point A in this graph will be:

$\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}$

Thus, the second option is correct.

There is one third of a pie shared equally between 5 children. How much of the pie does each child receive? one ninth pie one fi

adoni [48]

Answer:

Each of the 5 children receive one fifteenth pie

Step-by-step explanation:

Given:

One third of a pie shared equally between 5 children.

To find:

Amount of the pie with each of the 5 children.

Solution:

Number of children = 5

Also, one third of a pie shared equally between 5 children.

So,

Amount of the pie with each of the 5 children $=\frac{\frac{1}{3} }{5}=$ $\frac{1}{15}$

Hence, each of the 5 children receive one fifteenth pie.

During a stretch of 5 games, Stephen Curry averaged 42 points per game. In his first 4 games he scored 45, 48, 32, and 40 points

makkiz [27]

First, I will add up the know amount of points Chef Curry scored
45 + 48 + 32 + 40 = 165
To find the mean, add up all the numbers and divide that by how many values you had
I know 210 / 5 = 42, so I will subtract:
210 - 165 = 45
Cheer Curry scored 45 points
