Answer:

c

Step-by-step explanation:

Why is this? This is the only relation that passes the vertical line test.

The other choices have situations where we can draw a single straight vertical line through more than one point on the blue curve. That means the graph fails the vertical line test and we do not have a function.

For a function to be possible, any x input must lead to exactly one y output.

Answer:

x=-12

Step-by-step explanation:

4x−2(x+1)=3x+10

Step 1: Simplify both sides of the equation.

4x−2(x+1)=3x+10

4x+(−2)(x)+(−2)(1)=3x+10(Distribute)

4x+−2x+−2=3x+10

(4x+−2x)+(−2)=3x+10(Combine Like Terms)

2x+−2=3x+10

2x−2=3x+10

Step 2: Subtract 3x from both sides.

2x−2−3x=3x+10−3x

−x−2=10

Step 3: Add 2 to both sides.

−x−2+2=10+2

−x=12

Step 4: Divide both sides by -1.

−x/−1=12/−1

x=−12

Answer:

x=−12

Answer:

x=-12

Step-by-step explanation:

4x-2x-2=3x+10

2x-2=3x+10

2x-2+2=3x+10+2

2x=3x+12

2x-3x=3x+12-3x

-x=12

-x/-1 = 12/-1

x= -12

Answer:

3500 tickets were sold at $59

1000 tickets were sold at $85

(3500, 1000)

Step-by-step explanation:

x + y = 4500

59x + 85y = 291500

x + y = 4500

x = 4500 - y

59(4500 - y) + 85y = 291500

265500 - 59y + 85y = 291500

265500 + 26y = 291500

26y = 26000

y = 1000

x + y = 4500

x + 1000 = 4500

x = 3500

Check:

x + y = 4500

3500 + 1000 = 4500

4500 = 4500

59x + 85y = 291500

59(3500) + 85(1000) = 291500

206500 + 85000 = 291500

291500 = 291500

Answer:

what do you need help with?

Answer:

60 Degrees

Step-by-step explanation:

Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer

[tex]\frac{180}{3} =60[/tex]

Small and large angle are 60° and 120°.

Given that;

Angles are supplementary

Computation:

Assume;

Smaller angle = a

So,

Large angle = 2a

So,

In supplementary

a + b = 180

a + 2a = 180

3a = 180

a = 60

Smaller angle = 60°

Large angle = 2(60)

Large angle = 180°

The answer is

"She can read 216 words per minute because 72 divided by One-third is equal to 216."

Step-by-step explanation:

Given the statement

Susan can read 72 words in One-third of a minute ....pause

Whats is one-third of a minute

it is expressed as 1/3*60=20sec

so Susan can read 72 words in 20 second

this means that in a minute she can read

72+72+72 words= 216 word since 20sec*3 is 1 minute

alternatively

[tex]=\frac{72}{\frac{1}{3} }[/tex]

we then multiply 73 with the inverse of the denominator

=[tex]72*\frac{3}{1}[/tex]

=216 words

Answer:

Step-by-step explanation:

Each input should have one output.

Answer: C. (8, 16, 4)

Step-by-step explanation:

Given the following:

Let:

Trucks = T ; Cars = C ; SUVs = S

T =0.5(C + S) - 2 - - - (1)

C = 2T - - - (2)

T + C + S = 28 - - - (3)

T = 0.5(2T + S) - 2

T = T + 0.5S - 2

0 = 0.5S - 2

0.5S = 2

S = 2/0.5

S = 4

From T + C + S = 28

C = 2 T ; S = 4

T + 2T + 4 = 28

3T = 28 - 4

3T = 24

T = 24/3

T = 8

From T + C + S = 28

8 + C + 4 = 28

12 + C = 28

C = 28 - 12

C = 16

Hence, (T, C, S) = (8, 16, 4)

A number minus 8 is the same as a number divided by 2.

We have to find that number[tex].[/tex]

Let the number be x.

From the given question,

1. Number minus 8

2. Number divided by 2

ATQ : (I) = (II)

⭆ x - 8 = x/2

⭆ 2(x -8) = x

⭆ 2x - 16 = x

⭆ 2x - x = 16

⭆ x = 16

Answer:

(2,0) and (-1/3,0)

x = 2

x = -1/3

Step-by-step explanation:

Hi there!

You'll notice that this equation is a quadratic. When graphed, this equation looks like a parabola that crosses the x-axis at two points, which can be written as ordered pairs with an x value and a y value.

We know that both of these points will have a y value of 0, but we don't know what the x values of the points are—these are what we want to find.

(Check out the graphing program Desmos—type in your equation and it will graph it out for you.)

Notice that your equation follows this structure:

[tex]ax^2+bx+c=0[/tex]

In our case,

[tex]a=3\\b=-5\\c=-2[/tex]

We can plug our values of a, b, and c into the quadratic equation to find the two x values.

I've attached a picture of my work. At the top is the quadratic equation. I substituted our values in and solved.

You'll notice that the answer I ended up with has a ± symbol. We have to simplify this down two different ways to get our two answers: once using the plus sign, once using the minus sign. This will give us two different values for x.

We'll start with the plus sign:

[tex]\frac{5+7}{6} \\=2[/tex]

So: one of our x values is 2.

Now the minus:

[tex]\frac{5-7}{6} \\=-\frac{1}{3}[/tex]

Our other x value is -1/3.

You can check to make sure these answers work by plugging them back into the original equation for x. If they work, the left side of the equation should boil down to 0.

Let me know if you have any other questions! Best of luck with getting caught up in Algebra!

Answer:

Yea its B- Spain

Step-by-step explanation:

Answer:

(2x+7)° + (5x+4)° + 69° = 360°

=> 2x + 7 + 5x + 4 + 69 = 360

=> 7x + 80 = 360

=> 7x = 360 – 80

=> x = 280/7

=> x = 40

Answer:

x=40

Step-by-step explanation:

(2x+7)*+(5x+4)*+69*=360*   (360* because its a circle)

7x+80=360       (combine like terms)

- 80     -80      (minus 80 both sides)

7x=280      (divide 7 both sides)

x=40

Answer:

  7)  (f+g)(x) = 4^x +5x -5

  8)  (f-g)(x) = 4^x +x +5

Step-by-step explanation:

7) add the two expressions.

  (f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)

  (f+g)(x) = 4^x +5x -5

__

8) subtract g(x) from f(x).

  (f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5

  (f-g)(x) = 4^x +x +5
