Evaluate the expression for the given value of x. 8x + 7 for x = 4

Answer:

look at the picture i have sent

Answer:

BHM = 64°

x = 16°

Step-by-step explanation:

BHL is 90° and MLH is 26°. This means to find BHM, we have to subtract 26 from 90.

90 - 26 = 64°

BHM = 64°

BHM is also equal to 4x.

So, to find x, divide 64 by 4.  (64 = 4x  -->  64 ÷ 4 = x)

64 ÷ 4 = 16

x = 16°

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.

Answer:

40 points

Step-by-step explanation:

40 + 20 = 60

100 - 60 = 40

so round three equals 40 points

Answer:

60 points in round 3

Step-by-step explanation:

Since the total is 100, and they already got 40 points (from round 1 and 2) then just subtract them from the total to find what you got in round 3.

Answer:

You should buy 3 packages of beads that come in packages of 4 and 1 package of beads that come in packages of 12 to have an equal number of each of the different kinds of beads.

Step-by-step explanation:

Since the different kinds of beads Jen is using to make purses come in packages of 4 and 12, to determine what is the least number of each kind of bead Jen can buy to have an equal number of each of the different kinds of beads the following calculation must be performed:

12/4 = 3

4 x 3 = 12

Thus, you should buy 3 packages of beads that come in packages of 4 and 1 package of beads that come in packages of 12 to have an equal number of each of the different kinds of beads.

Step-by-step explanation:

Answer:

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.

Answer:

Step-by-step explanation:

area of sector=πr²/4=π ×6²/4=9 π ft²

area of one triangle= 1/2×6×6=18 ft²

area of three triangles=3×18=54 ft²

area of sector +area of three triangles=54+9 π ft²

area of circle=π×6²=36 π ft²

area of shaded region=36 π-9π-54=27 π-54=27(π-2) ft²

Answer:

From SOHCAHTOA

Cos17=73/y

y=73/cos17

y=76.34cm

Option B

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!!!!

8x + 6 = 4x + 38

4x + 6 = 38

4x = 32

x = 8

4(8) + 38

32 + 38

= 70

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

Answer:

you are absolutely correct .........

[tex]cosec( \theta) = \frac{1}{sin( \theta)} [/tex]

[tex]sin( \theta) = \frac{opposite}{hypotenuse} [/tex]

[tex]cosec( \theta) = \frac{hypotenuse}{opposite} [/tex]
