Answer: I believe his earnings would be 187$ once he teaches 7 classes.

Step-by-step explanation:

$187-$68=$111

17 x ? = 119

(take the 17$ which is the amount of money he'll earn each class and divide by 111. as seen below:

$111/17$=$6.5 (round to $7)

(you then plug in the 17 for 7 x ? = 119)

7x17=119

now you have to add the 68$ that he will get per month.

119+68=187

then you get 187$ which he had spent on the certificate

If F (7) 22, Then F(f-1(22))

jeka57 [31]

Answer:

$\boxed{\boxed{f(f^{-1}(22))=22}}$

Step-by-step explanation:

$\text{If we have}\ f(x)\ \text{and}\ f^{-1}(x),\ \text{then}\\\\\text{if}\ f(a)=b,\ \text{then}\ f^{-1}(b)=a.\\\\\text{Therefore, if}\ f(7)=22,\ \text{then}\ f^{-1}(22)=7.\\\\f(\underbrace{f^{-1}(22)}_{=7})=f(7)=22$

3. Find the equations of the lines that form the sides to the polygon shown below. What type of polygon is it? Explain your reas

borishaifa [10]

Answer: The question is not complete. the figure is attached below.

The polygon is a rectangle.

Step-by-step explanation:

Line 1 goes through (-2, 3)

hence the slope of line 1 = -3/2

Line 2 goes through (0, 3) (2, 0)

hence the slope of line 2 = -3/2

Line 3 goes through (0, 1) (-3, 1)

hence the slope of line 3 = 2/3

Line 4 goes through (3, 0) (0, -2)

Hence the slope of line 4 = 2/3

therefore -3/2 * 2/3 = -1

Line1 + Line3 Line1 + Line4 Line2 + Line3 Line2+Line4

because, the distance between Line1 and Line2 is not equal to that Line3 and Line4.

The polygon is a rectangle polygon.
