Which graph represents a proportional relationship

Answer:

C

Step-by-step explanation:

it is the only one with the variable in the spot of the per an hour which is what the equation is supposed to represent

Answer: the answer

we use the formula 1/2 .b .h

Step-by-step explanation:

the answer is 1,134, we substitute the t to 9 for each number, for example 4(9) 7(9)

4(9)= 36

7(9)=63

now we find the half of our bottom number which is 4=36

1/2 36= 18

so now we have 18x63=1,134

so our answer is 1,134

The area of the triangle is 1134 m²

What is the area of Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

Given data ,

The value of t = 9 m

Let the base of the triangle be b = 4t

                                                       = 4 x 9

                                                       = 36 m

Let the height of the triangle be h = 7t

                                                         = 7 x 9

                                                         = 63 m

Now , the area of the triangle = ( 1/2 ) x Length x Base

So , substituting the values , we get

Area of the Triangle = ( 1/2 ) x 36 x 63

                                 = 18 x 63 m²

                                 = 1134 m²

Therefore , the area is 1134 m²

Hence , the area of the triangle is 1134 m²

Answer:

1. x = 3

2. x = 8

3. x = 5

4. x = 8

Step-by-step explanation:

1. 18 = 6x

divide both sides by 6

x = 3

2. x + 7= 15

subtract 7 from both sides

x = 8

3. 2x - 2 = 8

add 2 to both sides

2x = 10

divide 10 by 2

x = 5

4. -1 + x = 7

add 1 to both sides

x = 8

Answer:

[tex]\sqrt{28[/tex]

Step-by-step explanation:

a^2 + b^2 = c^2.

if you draw out the triangle, you can substitute numbers into an equation.

6^2 + b^2 = 8^2

36 + b^2 = 64

b^2 = 64 - 36

b^2 = 28

b = [tex]\sqrt{28}[/tex]

Answer:

C

Step-by-step explanation:

It is C because I can plot all those points and they are still on the blue line. If you don't believe me, plug them in to y=-3/2x+2, (-4,8 plugged in would look like this 8=-3/2(-4)+2 just plug the x and y coordinates in) and they will be correct.

Hope this helps plz hit the crown:D

Answer:

B

X can be any real number, there are a lot of solutions for y = -3/2x+2 so the answer is not C or D

for a given x,y can only be y=-3/2*x+2 not any value y so the answer is not A

Since for a given x,y can only be y=-3/2*x+2 the solutions will be ~x,y = -3/2*x+2) or ~x, -3/2*x+2~ for all real numbers

Answer:

A senior citizen costs $8

Step-by-step explanation:

Represent senior citizens with S and children with C.

The first day is represented as:

[tex]3S + C = 38[/tex]

The second day is represented as:

[tex]3S + 2C = 52[/tex]

Required

Solve for C and S

Make C the subject in the first equation

[tex]C = 38 - 3S[/tex]

Substitute 38 - 3S for C in the second equation

[tex]3S + 2(38 - 3S) = 52[/tex]

[tex]3S + 76 - 6S = 52[/tex]

Collect Like Terms

[tex]3S - 6S = 52 - 76[/tex]

[tex]- 3S = -24[/tex]

Divide through by -3

[tex]S = 8[/tex]

Recall that: [tex]C = 38 - 3S[/tex]

[tex]C = 38 - 3 * 8[/tex]

[tex]C = 38 - 24[/tex]

[tex]C = 14[/tex]

Hence, a senior citizen costs $8

Answer:

We kindly invite you to see the explanation and images attached below.

Step-by-step explanation:

From Geometry we know that every line can be formed by knowing two two distinct points in a plane. Our stategy consist in using two distinct points for each linear equation in order to create our plot.

1) [tex]y = 2\cdot x + 2[/tex], [tex]A(x,y) = (0, 2)[/tex] and [tex]B(x,y) = (1,4)[/tex].

The line [tex]2\cdot y = 4\cdot x + 4[/tex] is a multiple of [tex]y = 2\cdot x + 2[/tex]. We present the graph below.

2) [tex]y = x-5[/tex], [tex]A(x,y) = (0,-5)[/tex] and [tex]B(x,y) =(1,-4)[/tex].

[tex]y = -x+3[/tex], [tex]C(x,y) = (0, 3)[/tex] and [tex]D(x,y) = (1,2)[/tex].

Finally, we proceed to plot each line and present the results below.

3) [tex]y = 2\cdot x-3[/tex], [tex]A(x,y) = (0,-3)[/tex] and [tex]B(x,y) = (1, -1)[/tex].

[tex]y = 2\cdot x + 4[/tex], [tex]C(x,y) = (0,4)[/tex] and [tex]D(x,y) = (1,6)[/tex].

Finally, we proceed to plot each line and present the results below.

Answer:

the amount of her annual benefit is $24,000

Step-by-step explanation:

The computation of the amount of her annual benefit is as follows:

= Given percentage × average salary × number of years of service

= 2% × $80,000 × 15 years

= $24,000

Hence, the amount of her annual benefit is $24,000

We simply applied the above formula so that the correct value could come

And, the same is to be considered

Based on the information given the amount of her annual benefit is $24,000.

Using this formula

Annual benefit= Annual retirement benefit percentage × Average salary × Years of service

Where:

Annual retirement benefit percentage=2% or 0.02

Average salary=$80,000

Years of service=15 years

Let plug in the formula

Annual benefit= 0.02 × $80,000 × 15 years

Annual benefit=$24,000

Inconclusion  the amount of her annual benefit is $24,000.

Algebra I

Step-by-step explanation:

From the graph we see that our y-values span from -4 to 4. When y = -4, it is a open dot, meaning it is exclusive. When y = 4, it is a closed dot, meaning it is inclusive. Therefore, our range is:
