the answer is not x=3, y=3

Given:

The graph of an invertible function [tex]f[/tex] is given.

To find:

The value of [tex]f^{-1}(-3)[/tex].

Solution:

We know that, if the graph of an invertible function [tex]f[/tex] passes through the point (a,b), then the inverse function [tex]f^{-1}[/tex] passes through the point (b,a).

From the given graph it is clear that the graph of the function [tex]f[/tex] passes through the points [tex](-5,-3)[/tex].

So, the inverse function [tex]f^{-1}[/tex] must be passes through the point [tex](-3,-5)[/tex].

Therefore, the value of inverse function is [tex]-5[/tex] at [tex]x=-3[/tex]. So, the value of [tex]f^{-1}(-3)[/tex] is [tex]-5[/tex].

Answer:

70.3km

Step-by-step explanation:

When the bearings are visualized and the points connected as a triangle, The angle x would be the difference of the both bearings from x

i.e 117-41 = 76

Using cosine rule,

YZ²= 43² + 67² - 2 x 43 x 67

cos76

YZ= √4944

= 70.3

Answer:

order of operation

first subtract 4 from both sides

then it is 6d=30

then divide by 6 and your answer if 5

ANSWER=5

please mark brainliest

Step-by-step explanation:

Answer:

4 + 6d = 34

6d = 34 - 4

6d = 30

d = 30 : 6

d = 5

Answer:

MP =8

Step-by-step explanation:

QR = 1/2 MP

76 -8x = 1/2 (89 - 9x)             Multiply both sides by 2

152 - 16x = 89 - 9x                Subtract 89 from both sides

152-89 - 16x = - 9x                Add 16x to both sides.

63 - 16x +16x = 16x  - 9x

63 =7x                                  Divide by 7

x = 63/7

x = 9

MP = 89 - 9*9

MP = 8

Answer:

54 kg

Step-by-step explanation:

Total weight of 7 boys is 392 kg. And other 6 boys total weight is 338 kg.

So the 7th boy's weight is (392-338)=54 kg

Answer:

54

Step-by-step explanation:

338÷6=56.33

so it means that 7th boy is less than 56

338+54=392

392÷7=56

Answer:Do rise over run, maybe watch a tutorial on it, pretty simple method

Answer:

there are only three simple steps (:

Step-by-step explanation:

1. identify the two points on the line

2. select one to be (x1, y,1) (rise over run) and the other to be (x2, y2)

3. use slope equation to calculate your slope (m=rise/run= y2-y2/x2-x1)

in the equation of a straight line (equation written y=mx+b) the slope is m and b is the y intercept. (where the line crosses the y axis) this is the slope intercept form)

Answer:

1 up and 5 to the right (if d is the translated figure)

Answer:

A translation of +9 units on the x axis (to the right) and +3 on the y axis (up), assuming D is the figure that was translated.

Step-by-step explanation:

Angle B = 54°

Step-by-step explanation:

complimentary means they add up to 90

54 + 36 (angle A) = 90

also x= 51

Answer:

m∠B = 54°

Step-by-step explanation:

Note: Complementary angles add up to 90°

Thus, m∠A and m∠B must add up to 90.

We can then write this equation.

x - 15 + x + 3 = 90

Simplify.

2x - 12 = 80

Add 12 to both sides.

2x = 102

x = 51

m∠B is (x + 3) , so m∠B = 51+ 3 = 54°

Just in case, let's double check. Plug 39 for x into m∠A to get

m∠A = 51 - 15 = 36

Then, plug the angle measures in.

36 + 54 = 90

90 = 90

Thus, the answer is correct.

I hope this helps! Feel free to ask any questions! :)

Answer:

2/10 or 20%

Step-by-step explanation:

Because 4 and 8 are the only numbers 1-10 that are divisible by four.

This would give Amy a 2/10 chance of rolling a number divisible by 4.

To turn 2/10 into a percent, the denominator has to be 100 so if you multiply 10 by 10 you will get 100, you will also have to multiply 2 by 10 to get 20 and you will get 20/100

20/100 is equal to 20%

Therefore your answer would be 2/10 or 20%
