The angle measurements in the diagram are represented by the following expressions.

Mathematics
1 answer:
Ivan3 years ago
8 0

Step-by-step explanation:

Angles A and B are Alternate Exterior angles, therefore they are congruent.

=> 8x + 6° = 4x + 38°

=> 4x = 32°, x = 8°

Hence Angle B = 4(8°) + 38° = 70°.

Answer:

(-4,-1)

Step-by-step explanation:

-3x+10y=2

-3x+3y=9

-3x=2-10y

-3x=9-3y

2-10y=9-3y

2-9=10y-3y

7y=-7

y=-1

-3x+3(-1)=9

-3x-3=9

-3x=12

x=-4

An ostrich can run at a rate of 50 miles in 60 minutes.
defon
So 50 miles/60 minutes and you basically just convert it
you want to divided by 10 so you will get
5miles/6minutes
and then multiply both by 3 and you will get 18

so it takes 18 minutes

T(x)=1-2x how do you graph this problem
Eva8 [605]

Answer:

Explained

Step-by-step explanation:

The 1 is the y-intercept

The -2 is the slope

First place a point at (0,1)

Then, because it's negative from left to right the graph is decreasing (going lower on the y-axis the farther you go on the x-axis).

Slope is rise over run so the -2 affects how far it goes. So for each value of x that increases by one, a new point will be two units down and one unit right of the previous point. To graph to the left of the y-intercept then you do that backwards where the next point is two units up and one unit left.


Then just draw a straight line connecting all the points.

Answer:

f^{-1}(6) = 50

Step-by-step explanation:

Given

f(x) = \sqrt{2x} - 4

Required

Find f^{-1}(6)

First, we calculate the inverse function

f(x) = \sqrt{2x} - 4

Express f(x) as y

y = \sqrt{2x} - 4

Swap the positions of x and y

x = \sqrt{2y} - 4

Solve for y: Add 4 to both sides

4 + x = \sqrt{2y} - 4+4

4 + x = \sqrt{2y}

Square both sides

(4 + x)^2 = 2y

Divide both sides by 2

y = \frac{(4 + x)^2}{2}

Express y as an inverse function

f^{-1}(x) = \frac{(4 + x)^2}{2}

Next, solve for: f^{-1}(6)

Substitute 6 for x

f^{-1}(6) = \frac{(4 + 6)^2}{2}

f^{-1}(6) = \frac{(10)^2}{2}

f^{-1}(6) = \frac{100}{2}

f^{-1}(6) = 50
