Step-by-step explanation:

I did it the wrong way. Sorry

Answer:

Step-by-step explanation:

First you take the 142+B=180

because those 2 are supplementary

B=38

and you see the 2 lines on the 2 sides that means those two sides are equal to each other and the angles corresponding with them are also equal to each other.  

and a triangle=  180 degrees

A and E are the same so A=E

180-B(38)= 142

and because A=E you do 142/2= 71

and now that you have A and E you don't need A or B for the last part so

E+(x)=180 because those two angles are supplementary.

and E is 71 so...

71+(x)=180  ---------180-71=x

X=109

Answer:

The answer is below

Step-by-step explanation:

A composite function is a function which is placed inside another function, this type of function can be calculated by substituting one function into another function.

If two functions g(x) and f(x) are inverses, then each will reverse the effect of the other. That is, (f○g)(x)=f(g(x))=x and (g○f)(x)=g(f(x))=x.

Given that F(x) =(x+4)/3 and g(x) = 3x – 4

a) (f o g)(x) = f[g(x)]

   = f(3x - 4)

   = [(3x - 4) + 4]/3

   = [3x - 4 + 4]/3

   = 3x / 3

   = 3

b) (g o f)(x) = g[f(x)]

   = g[(x + 4)/3]

   = 3(x + 4)/3 - 4

   = x + 4 - 4

   = x

We can see that (f o g)(x) = (g o f)(x) = x. Hence the functions are inverse functions.

Step-by-step explanation:

A triangular prism is a polyhedron (three dimensional shape) made up of two equal triangles, two equal rectangle and a base rectangle.

The total surface are of a triangular prism is given as:

A = bh + 2ls + lb

where b is the base of the triangle, h is the height of the triangle, l is the length of the base rectangle and s is the length of the slant side of the triangle.

Given that:

b = 6 ft, s = 5.5 ft, h = 5 ft, l = 9 ft.

Therefore:

A = (6 * 5) + 2(9 * 5.5) + (9 * 6) = 183 ft²

Therefore 183 ft² of fabric is needed to make the tent

Answer:

1,350 = 40 r + 50 r

Step-by-step explanation:

40 x 15 = 600

50 x 15 = 750

600 + 750 = 1,350

Answer:

135

Step-by-step explanation:

Ratio = 3 : 9

Angles are : 3x , 9x

3x + 9x = 180         {supplementary angles}

   12x   = 180  {divide both side by 12}

       x = 180/12

x = 15

Larger angle = 9x = 9*15 = 135

Answer:

y = -8/3x - 11

Step-by-step explanation:

(-6, 5) and (-3, -3)

Slope:

m=(y2-y1)/(x2-x1)

m=(-3-5)/(-3+6)

m=(-8)/3

m= -8/3

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = -8/3(x + 6)

y - 5 = -8/3x - 16

y = -8/3x - 11

The number of trips that Molly and Tess did was 7.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

As per the given,

Molly has $280 in her bank account and spends $40 on every trip.

Number of trips = Account balance / spent in every trip

⇒ $280/$40 = 7

Hence "The number of trips that Molly and Tess did was 7".

Answer:

you wold have to graph it just put it in the caculater like that

Step-by-step explanation:

Answer: y- 2 = -1/2(x - 2)

Step-by-step explanation:

We need to rewrite it as y=mx+b.

x - 2y = 4

    2y = - x + 4

       y = -1/2x + 4/2

        y = -1/2x + 2

The slope for x - 2y = 4 is -1/2.

In addition, the slope of two parallel line would be the same, the slope of the line that pass through the point (2,2) would be -1/2.

y- y1 = m(x- x1)

y- 2 = -1/2(x - 2)

Answer:

.80

Step-by-step explanation:

Hey There,

Cosine = adjacent / hypotenuse

the adjacent of c is 16

the hypotenuse is 20

so cos C = 16/20 or .80

Answer:

Step-by-step explanation:

cos=(adjacent side)/(hypotenuse)

cosC=16/20

cosC=4/5

cosC=0.80 (to nearest hundredth)

Answer:

x = 17/18

Step-by-step explanation:

-5(7-8x) -7x = -(3x+1)

-35 + 40x - 7x = -3x - 1

-35 + 33x = -3x - 1

33x + 3x = -1 + 35

36x = 34

x = 34/36

Answer:

8

Step-by-step explanation:  

x=average

(x+x+x+x)/4=average

to increase x by 2 you add 2

x+2=average

(x+2+x+2+x+2+x+2)=4=(4x+8)/4=x+2

you'd have to increase the sum by 8 to make the numbers' averages' go up by 2

Answer:

y<14/3

Step-by-step explanation:

−3y < −14

dividing both side by -3

-3y/-3 <-14/-3

y<14/3

The solution of the inequality will be equal to y<14/3.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given inequality will be solved as,

−3y < −14

Dividing both sides by -3 and solving further.

-3y/-3 <-14/-3

y < 14
