Hello, just need the answer for this question. Thank you for your help if you do so.
musickatia [10]

Answer:

In the first one you are missing (x - 3) so it will be 4(x - 3) and if you factor it out it will be 4x - 12

In the second one you are missing a (x -5)which means 9x(x -5) or when you factor it out it will be 9x^2 - 45x

Step-by-step explanation:

3x^2 -23x + 40 = (3x - 8) (x - 5)

3x^2 -17x + 24 = (3x -8) ( x - 3)

What equation represents the inverse of y = e^2x - 9?
love history [14]

The inverse of this function is y = \frac{ln(x + 9)}{2}


You can find the inverse of any function by switching the x and y values. Once you've done that, you can solve for the new y. The result will be the inverse of the function. The work for this one is below.


y = e^{2x} - 9 ----> Switch the x and y


x = e^{2y} - 9 -----> Add 9 to both sides


x + 9 = e^{2x} ----> Take the natural log (ln) of both sides. This will case the e to cancel on the right side.


ln(x + 9) = 2y ----> Divide both sides by 2.


y = \frac{ln(x + 9)}{2}


This will be your inverse function.

Substitute and find the value of the variable not given using the following equation: d = rt; t = 8, r = 2
Romashka-Z-Leto [24]
You are looking for the value of d.

Given, t = 8 and r = 2

d=r * t
d= (2)*(8)
d=16

Suppose each square on the grids below is 1 cm by 1 cm. Estimate the area of the figure.
Anvisha [2.4K]

Answer:

About 20cm^2

Step-by-step explanation:

In the given image each of the square has side 1 cm by 1 cm.

If we could count the whole squares in the image we can see that there are about 14 whole squares, then there are 6 squares which are nearly half occupied so that makes about 3 whole squares. And then there are almost 12 squares whose quarter area is enclosed by the lines so that makes about 3 whole squares.

So the total area of the given figure is about 20 cm^2.
