Answer:
y=2/3x-5
Step-by-step explanation:
First, let's put this equation into slope-intercept form.
2x-3y=24
-3y=-2x+24
y=2/3x-8
For two lines to be parallel, they must have the same slope. Therefore our slope is 2/3.
Now, we must find b. To do that we can plug the y and the x in.
-7=2/3(-3)+b
-7=-2+b
-5=b
y=2/3x-5
X³ - 9x² + 5x - 45
x²(x - 9) - 5(x - 9) ⇒ x³ - 9x² - 5x + 45 INCORRECT
x²(x + 9) - 5(x + 9) ⇒ x³ + 9x² - 5x - 45 INCORRECT
x(x² + 5) - 9(x² + 5) ⇒ x³ + 5x - 9x² - 45 CORRECT
It just needs to be rearranged.
x(x² - 5) - 9(x² - 5) ⇒ x³ - 5x - 9x² + 45 INCORRECT

Step-by-step explanation:
divide by 3 you get 3 pounds
Answer:
Option D = 144
Step-by-step explanation:
First, you are not putting the expression correctly. I'm assuming you are mean to say (ab)². This is because if you want to multiply by 2, the 2 usually goes first like this 2ab. But it's not case, so, it should be as I said.
Now, let's replace the values for a and b into the expression:
(ab)² = (4 * 3)² = (12)² = (12*12) = 144
That's is why is option D.
Answer:
<em>A ≈ 3215.36</em>
Step-by-step explanation:
A = πr²
Radius - D/2
Radius - 64/2 → 32
A = 3.14(32)²
A = <em>3215.36</em>
Hope this helps! :)
