Step-by-step explanation:
So visually youre given the function
for h(-4) it can also be written as h(-4) = y
what do you get for y when you substitute - 4 for x?
All you have to do is trace the line until you get to x=-4 and then find the y that corresponds to it (looks like around y= - 1)
for the other one h(x) = - 5
what do you get for x when you substitute - 5 for y?
what you do is similar, trace the line along the y-axis and see what x-value you get for y =-5
Answer:
3 and x = 0
Step-by-step explanation:
To find the value of h(- 4)
Locate x = - 4 on the x- axis, go vertically up to meet the graph at (- 4, 3 )
Then the value of h(- 4) = 3
For h(x) = - 5
Locate y = - 5 on the y- axis. This is the point (0, - 5)
then the value of x for which h(x) = - 5 is x = 0

Answers
answer:
∠B = 70°
step-by-step explanation:
as you can see, the angle are alternate exterior anglestherefore, they are EQUALwe can set them equal to each and solve for x first∠A = ∠B
8x + 6 = 4x + 38
4x + 6 = 38
4x = 32
x = 8
now, we will plug in x in the expression for B to find B4(8) + 38
32 + 38
= 70
therefore, ∠B = 70° and x = 8Find each probability below -- as a fraction, decimal and percent

Answer:
1. tan(x) = 9/20
arctan(9/20) ≈ 24.23°
2. cos(x) = 17/32
arccos(17/32) ≈ 57.91°
3. tan(x) = 13/18
arctan ≈ 35.84°
4. sin(x) = 21/28
arcsin(21/28) ≈ 48.59°
Answer:
1 x = 24.2°
2 x = 57.9°
Step-by-step explanation:
You must memorize the definitions of the trig functions and then these problems are easy
1: tan = opposite side/adjacent side
opp side to x is 9 and adjacent side is 20
So, tan x = 9/20
x = arctan (9/20) = 24.2°
2: cos = adjacent side/hypotenuse
adjacent side = 17 and hypotenuse = 32
cos x = 17/32
x = arccos (17/32)
x = 57.9°
You do 3 and 4. Hint: Use the tan function in 3 and the sine function in 4
OK? You can do it!!!!
sum of two numbers be 95. if one exceeds the other by 15, find the number
Answers
Sum of two number = 95
Let the first number be x, then another number be x + 15.
According to the question, x + x + 15 = 95
=>2x+15=95
=>2x+15-15=95-15
=>2x=80
=>x=40
Hence, the first number = 40
And another number = 40 + 15 = 55.

The measure of an angle is 2.8.what is the measure of its complementary angle
Answers
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
87.2°Step-by-step explanation:
When angles are complementary, it means that they both add up to 90°.
In this case, one of the angles measures 2.8°.
So, to find the other one, we subtract 2.8 from 90.
90 - 2.8 = 87.2
The measure of the complementary angle is 87.2°

option A : 7x - 1
Step-by-step explanation:
Area of the shaded region = [ Area of bigger rectangle] - [Area of smaller rectangle ]
Therefore, Area of bigger rectangle = length * breadth = (x - 1)(x + 5)
Therefore, Area of smaller rectangle = length * breadth = (x + 1)(x - 4)
Area of shaded region = [(x - 1)(x + 5)] - [(x + 1) ( x - 4)
= [x(x + 5) - 1(x + 5)] - [x(x - 4) + 1( x - 4)]
= [ x^2 + 5x - 1x -5] - [ x^2 - 4x + 1x - 4]
= x^2 + 5x - 1x - 5 - x^2 + 4x - 1x + 4 ....(after removing the brackets)
= x^2 - x^2 + 5x + 4x - 1x - 1x - 5 + 4.....( as (+ x^2 )and (- x^2 )get eliminated due to opposite signs)
= 9x - 2x - 1
= 7x - 1
So, option A: 7x - 1 is the correct answer.

Area of figure 2 = 150 square cmWX = 25/6 cm (exact)WX = 4.167 (approximate)It's not clear which version of WX your teacher wants, so I provided both of them.
============================================================
Explanation:
Focus on the perimeters. The jump from 36 to 30 means the linear scale factor is 30/36 = 5/6
This means,
WX/YZ = 5/6
WX/5 = 5/6
6WX = 5*5
6WX = 25
WX = 25/6 which is exact
WX = 4.167 approximately
---------------
The linear scale factor is 5/6, so the area scale factor is (5/6)^2 = 25/36.
The area of figure 1 is 216 cm^2, making the area of figure 2 to be 216*(25/36) = 150 cm^2
