Answer: x=−5

Step-by-step explanation:

8x+32=5x−3−4x

8x+32=x−3

8x+32−x=−3

7x+32=−3

7x=−3−32

7x=−35

The product of (4z^2 + 7z - 8) and (-z + 3) is -4z^3 + xz^2 + yz - 24. What is the value of x? What is the value of y?

ycow [4]

Answer:

$x=5+\frac{29}{z}-\frac{y}{z}$

$y=5z+29-xz$

Step-by-step explanation:

Given: $(4z^2+7z-8)(-z+3)=-4z^3+xz^2+yz-24$ ; find x and y.

Let's start with finding x first. Let's distribute the left side of the equation.

$-4z^3+5z^2+29z-24=-4z^3+xz^2+yz-24$

Let's move everything we can to the left side of the equation. Some things will cancel out.

$5z^2+29z=xz^2+yz$

Now, let's move the term that includes $x$ to the left side of the equation. Everything else should be moved to the right.

$-xz^2=-5z^2-29z+yz$

Let's get rid of the negative sign in front of $x$ by dividing both sides by -1.

$xz^2=5z^2+29z-yz$

To get $x$ completely isolated, divide both sides by $z^2$ .

$\frac{xz^2}{z^2}=\frac{5z^2}{z^2}+\frac{29z}{z^2}-\frac{yz}{z^2}$

Simplify.

$x=5+\frac{29}{z}-\frac{y}{z}$

Let's solve for y. We will start with the distributed and simplified equation to make it easier.

$5z^2+29z=xz^2+yz$

Now, let's move the term that includes $y$ to the left side of the equation. Everything else should be moved to the right.

$-yz=-5z^2-29z+xz^2$

Again, let's get rid of the negative sign in front of the $y$ by dividing both sides by -1.

$yz=5z^2+29z-xz^2$

To isolate y, divide both sides by z.

$\frac{yz}{z}=\frac{5z^2}{z}+\frac{29z}{z}-\frac{xz^2}{z}$

Simplify.

$y=5z+29-xz$

Refer to the equation 4x + 3y = 24

GuDViN [60]

Answer:

See explanation

Step-by-step explanation:

You are given the equation $4x+3y=24$

1. When x = 0, then

$4\cdot 0+3y=24\\ \\3y=24\\ \\y=8$

When y = 0, then

$4x+3\cdot 0=24\\ \\4x=24\\ \\x=6$

When x = 3, then

$4\cdot 3+3y=24\\ \\12+3y=24\\ \\3y=12\\ \\y=4$

Complete the table:

$\begin{array}{cc}x&y\\0&8\\3&4\\6&0\end{array}$

2. Use the table of values to graph the line. Plot two points (0,8) and (6,0) and connect them with a straight line. See attached diagram for details.
