Which of the following graphs below is the graph of a function?
(1)
(3)
(2)
(4)

Answer:

Step-by-step explanation: The slope is 10 because when x moved positive 2, y moved positive 20 so y = 10x + b and you can just pick one point that the line crosses so I will use (2, 40) so when you put that in the equation it is 40 = 20 + b so b is 20. The answer is y = 10x + 20

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the total monthly charges for x amount of class.

From the graph, the line passes through point (0,20) and (2, 40). Hence, the equation of the line is:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-20=\frac{40-20}{2-0} (x-0)\\\\y-20=2x\\\\y=2x+20[/tex]

Hence the equation for the line in slope-intercept form is y = 2x + 20

Step-by-step explanation:

y = 5x + 3

y = 5.5x + 2

0.5x = 1

x = 2

y = 13

Answer:

The answer is y = 13

y = 5.5x + 2

x = 2

(5.5 * 2) + 2

(11) + 2 = Y or 13

Answer:

The number of whole loaves at each location = 5 loaves

Step-by-step explanation:

This problem is essentially testing your ability to use simple division within remainders, and the number of whole loaves is calculated as follows:

Numer of loaves of bread = 16

number of locations = 3

next, we will divide the number of loaves by the number of locations since Olivia placed an equal number of loaves in 3 different locations:

[tex]= \frac{16}{3} = 5\frac{1}{3}[/tex]

This means that there will be 5 whole loaves and 1 loaf that will be divided equally into the three places.

Therefore, the number of whole loaves at each location = 5 loaves

but remember that there will be a remainder of 1 loaf.

Choice A) Real Numbers

Choice F) Rational Numbers

===============================================

Explanation:

Any number you encounter so far in your math class is a real number, assuming your teacher hasn't covered complex numbers yet. So -7/16 is a real number.

It is also a rational number. Rational numbers are of the form p/q where p and q are integers. The value of q cannot be zero. Since it is rational, that means it's not irrational.

Since -7/16 = -0.4375 has a fractional or decimal part, it is not a whole number, integer, or natural number. Those numbers only deal with values that don't have any fractional parts.

well, you can't solve an equation with just one number, at least not this equation. maybe if you show more of the graph, i could help.

Answer: The rental cost for each movie is $3.5  and each video game is $5.

Step-by-step explanation:

Let x= rental cost for each movie

y = rental cost for each movie video game.

As per given,

2x+5y = 32      (i)

8x+3y=43        (ii)

Multiply 4 on both sides of equation (i)

8x+20y = 128     (iii)

Eliminate (ii) from (iii)

17y=85

⇒ y = 5   [divide both sides by 17]

Put this in (i)

2x+5(5)=32

⇒ 2x+25= 32

⇒ 2x= 7

⇒ x  = 3.5    [divide both sides by 2]

Hence, the rental cost for each movie is $3.5  and each video game is $5.

Answer:

[tex]a=-4.47\ m/s^2[/tex]

Step-by-step explanation:

Given that,

Initial speed of a car, u = 60 mph = 26.82 m/s

Final speed of a car, v = 10 mph = 4.47 m/s

Time, t = 5 s

We need to find the acceleration of the car. The rate of change of velocity is called the acceleration of an object. It can be given by :

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{4.47 -26.82 }{5}\\\\a=-4.47\ m/s^2[/tex]

So, the acceleration of the car is [tex]4.47\ m/s^2[/tex] and it is deaccelerating.

Step-by-step explanation:

Answer: her speed was “44 miles per hour”

Assuming Ms. Larson was travelling at a constant speed in that half hour, her speed would have been 44 miles per hour.

In order to find the speed of something, use the formula:

= Distance / Time

The distance was:

= First distance from home - Second distance from home

= 120 - 98

= 22 miles

The time was half an hour so will be presented as:

= 0.5 hours

The speed is therefore:

= 22 / 0.5

= 44 miles per hour

In conclusion, Ms. Larson is going at 44 miles per hour.

the value of x is 5

Answer:

"The relationship is proportional."

"The relationship is proportional."

"The equation of the line is y = -3x"

Step-by-step explanation:

First, a proportional relationship can be written as:

y = k*x

where k is called the constant of proportionality. (or the slope)

You can see that if we take x = 0, we have

y = k*0 = 0

Then this type of line always passes through the point (0, 0).

And in the graph you can see that this line does that, then:

"The relationship is proportional." is true.

We also can see that as x increases, the value of y decreases, this must imply that k is a negative number, then:

"The slope is negative." is true.

To find the value of the slope, we can take two points that belong to the line.

I will choose:

(0, 0) and (2, -6)

For the slope, we just take the quotient between:

Δy = -6 - 0 = -6  (the difference in the y-components)

Δx = 2 - 0 =  2   (the difference in the x-components)

the slope is:

k = Δy/Δx = -6/2 = -3

Then the slope is -3, and we can write the equation as:

y = -3*x

Then:

"The equation of the line is y = -3x" is true.
