Answer:

f(x) = x^2 is a classic example

f( 3 ) = 9 and

f( -3 ) = 9, but

f^(-1)[9] is undefined because the result can be 3 and -3

Step-by-step explanation:

For no. 8

2x + 1°+ 33° = 90° { Being complementary angles }

2x + 34° = 90°

2x = 90° - 34°

2x = 56 °

x = 56° / 2

x = 28°

For no. 10

5x + 12 = 6x - 10 ( being vertically opposite angles)

6x - 5x = 12 + 10

x = 22

Hope it will help :)❤

Please help! 25 points!<br> Write the equation of a line with slope 3/2 and Y-Intercept -2.
Juli2301 [7.4K]
Hello there!

For this question, we can use slope-intercept form of a line. The following equation is the format for slope-intercept form:
y=mx+b

In this equation, m is the slope and b is the y-intercept. The slope and y-intercept is given. Thus, we just "plug in" the given values into the equation to get our answer. Replace "m" with "3/2" and replace "b" with "-2". After doing so, you get the following equation for the line.

y= \frac{3}{2} x-2

That should be your answer. Hope this helps! :)

So, lets make ratio with is 1/1 because for every 1 boat from other states, there is 1 boat for South Carolina.

There are 12 boats, divide them evenly to get the answer of 6 boats from South Carolina. The reason for dividing by two was due to the fact that half for South Carolina and half from other states. Now there is your answer.

6 x 89 is 534
6 x (90 - 1) is 534. BUT you have to subtract 90 from 1 and that's 89. So then you multiply 6 by 89.
6 x 90 is 540 and 6 x 1 is 6. you take 540 subtract 6 and that's 534.
540 - 6 is 534.

PLEASE HELP!

Answer:

Perimeter = 21.58 units

Step-by-step explanation:

Perimeter of a polygon = Sum of measures of all sides of the polygon

Perimeter of the quadrilateral LEAP = PL + AE + EL + LP

                                                            = 4.47 + 4.47 + 6.32 + 6.32

                                                            = 21.58 units

[If the distances between two point are not given, use the formula to calculate the distance between two points (x_1, y_1) and (x_2,y_2)

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}]
