All you gotta do is set each of the parentheses equal to zero and solve for x
Ex x+7=0 => x= -7
x+4=0 => x= -4

What value of x makes the equation true? 4x - 3= -9 + 7x
uysha [10]

Answer:

x = 2

Step-by-step explanation:

To find the x-value that makes the equation true, we would have to solve for x in the equation. To do that, we would have to get the equation in the form x = _. That would be our answer.

4x - 3 = -9 + 7x

Add 9 to both sides to get rid of the -9 on the right side.

4x - 3 + 9 = 7x

Simplify.

4x + 6 = 7x

Subtract 4x from both sides to get rid of the 4x on the left side.

6 = 7x - 4x

Simplify.

6 = 3x

3x = 6

Divide both sides by 3 to get rid of the coefficient of 3 on the left side.

x = 6/3

Simplify.

x = 2

So, the x-value that makes the equation true would be 2.

I hope this helps. :)

Adding a few more points to this one plz answer the question in the picture
Ne4ueva [31]

Answer:

The greatest number of arrangements possible would be 5

Step-by-step explanation:

If we look at the x values (in this case # of tulips remaining) we can find the number 20. And we see that there is a line going through it. We then stop at the point and go down to see what number it would fall on on the y axis.

Which expression finds the measure of an angle that is coterminal with a 45° angle? 45° 90° 45° 180° 45° 270° 45° 360°.
svetoff [14.1K]

Coterminal angles are measured from the positive x-axis. The coterminal angle for angle 45° is (270°+45°).

<h3>What are coterminal angles?</h3>

Coterminal angles are angles that are made by the positive x-axis of the coordinate plane.

Given to us

θ = 45°

We know that coterminal angles are those angles that are measured from the positive x-axis of the coordinate plane.

In order to find the angle coterminal with a 45° angle, we will deduct θ from 360°, therefore we will measure the from positive x-axis but in the clockwise direction.

\theta _1 = 360^o - \theta\\\\\theta _1 = 360^o - 45^o\\\\\theta _1 = 315^o\\\\\theta _1= 270^o + 45^o

Hence, the coterminal angle for angle 45° is (270°+45°).

(You will need a calculator.) Suppose you deposit $4800 into an account paying 3.2% simple annual interest and leave it there fo
STatiana [176]
The answer is 38,016. You have to multiply 4800 by 6 which equals 28,800. then multiple 0.32 times 4800 which equals 1538. multiply 1538 by 6 which equals 9,216 and then add 28,800 which equals it to 38,016.
