osted a new question: Solve: 3x+1= 7​

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

Given:

Height of statue or liberty from the ground = 305 feet

Model is [tex]\dfrac{1}{100}[/tex] the actual size of the statue of liberty.

To find:

The height of the model of statue.

Solution:

According to the question,

Model =  [tex]\dfrac{1}{100}[/tex] of the actual size

        [tex]=\dfrac{1}{100}\times 305[/tex]

        [tex]=3.05[/tex]

Therefore, the height of the model of statue is 3.05 feet.

Answer:

2/a = x

Step-by-step Explanation:

First you multiply both sides by 4, leaving you with -12 = ax - 14. Then you add 14 to both sides, which gives you 2 = ax. Then divide both sides by a, where you get your answer, 2/a = x

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.

Everything except the finding the midpoint

Step-by-step explanation:

If the question states the points of a shape, you can find the perimeter and the area of the polygon because you would know the dimensions and the lengths of each side, but in the options, it says the area of a rectangle, and it doesn't have to be a rectangle

You can find the equation of the circle, by finding the diameter of the circle and the radius. With the diameter, you would be able to find the centre of the circle and then you need to divide the diameter by two to get the radius.

For the midpoint, you use the midpoint formula. You just need to sub in the points into the formula and you would get the midpoint

When you are given two points on a graph (or worded problem), and it says that for every x number of km it uses y amount of gas and the question asks to find how much gas is needed in between these two points, you can do this.

Step-by-step explanation:

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.

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.
