The equation y = 8.1x models the relationship between the number of hours Alexander works, x, and the dollar amount he earns, y. Which is the graph of the equation y = 8.1x?

Answer:

x > 2

Step-by-step explanation:

x is the hours of accumulation.

3/2 *2 = 3

Equations:

A + T = 735 naira

A = T + 95

A + T = 735

A - T = 95

Add and solve for A:

2A = 830

A = 415 naira

T = 735-415 = 320

Abiodun and Taiwo got 415 & 320 naira , respectively.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

Abiodun and Taiwo share 735 naira between them so that Abiodun gets 75naira than taiwo.

now, we get

A + T = 735 naira

A = T + 95

A + T = 735

A - T = 95

Add and solve for A:

2A = 830

A = 415 naira

T = 735-415 = 320naira

Hence, Abiodun and Taiwo got 415 & 320 naira , respectively.

Answer:

38 units (rounded off to the nearest unit)

Step-by-step explanation:

The perimeter of the given figure will be 38 units.

Its the sum of length of the sides used to made the given figure.

We are given that Measures of three linear sides as 5, 10, 10, 5 units.

Radius of the circular part = 5 units

Since Perimeter of a polygon = Measure of the circumference of the polygon

The Perimeter of the figure = measure of the three straight lines + measure of the circumference of the quarter circle

Thus Measure of linear sides = 5 + 10 + 10 + 5 = 30 units

Circumference of the quarter circle =  2πr

=  2π(5)

= 7.85 units

Perimeter of the figure = 30 + 7.85

                                     = 37.85

                                     ≈ 38 units

Therefore, the perimeter will be 38 units.

Answer:

[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)[/tex]

Step-by-step explanation:

To see which equations have the slope of 3/4, we just need to focus on the right half of the equations to see what the multiplier of x is.

Equations 1 and 3 can be eliminated because they have a slope of [tex]\frac{1}{3}[/tex] and 4 respectively.

Now we can decide between 2 and 4 by plugging in the point [tex](4,\frac{1}{3})[/tex] to see which works properly.

Simplify equation 2

[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)\\\\y-\frac{1}{3} =\frac{3}{4}x-3\\\\y=\frac{3}{4}x-\frac{8}{3}[/tex]

Plug in the point

[tex]\frac{1}{3} =\frac{3}{4}(4)-\frac{8}{3} \\ \\\frac{1}{3} =3-\frac{8}{3} \\\\\frac{1}{3} =\frac{9}{3} -\frac{8}{3} \\\\\frac{1}{3} = \frac{1}{3}[/tex]

This checks out, so equation 2 is your answer.

Complete question :

On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?

Answer:

1.6 hours

Step-by-step explanation:

Given the function :

Time t taken for flying distance d is given by:

t = 1/500 * d

Tine taken to fly 800 miles;

d = 800 miles

t = 1/500 * (800)

t = 800 / 500

t = 1.6

Hence, time t = 1.6 hours

Step-by-step explanation:

Happy to help! The best way to find if it is a solution is to look for those points on the graph. When we graph the point, it needs to fall in an area where both lines or shaded or on a solid line.  

Look carefully and see if you can find points like these!

(0, -2) falls on a solid line.  

(1, 1) falls in the double shaded area.

Therefore, (0, -2) and (1, 1) both work in this system of equations.

Step-by-step explanation:

A = Surface area of the Earth = [tex]1.5\times 10^8\ \text{km}^2[/tex]

Total number of people on Earth = 7.594 billion as of 2018 = [tex]7.594\times 10^9[/tex]

We need to find the number of people living in each square km of land area.

So, we need to divide the number of people by the land area of the Earth.

[tex]1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}[/tex]

[tex]\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}[/tex]

[tex]\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}[/tex]

So, 51 people will inhabit each square km of land area.

The equaiton of the line is y = (5/6)x + 7/2. Then the slope of the line is 5/6.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The two points are (9, 11) and (3, 6).

The equation of the line that passes through (9, 11) and (3, 6) will be given as,

(y - 6) = [(11 - 6) / (9 - 3)](x - 3)

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

y - 6 = (5/6)x - 5/2

y = (5/6)x + 7/2

The equaiton of the line is y = (5/6)x + 7/2. Then the slope of the line is 5/6.

Answer: x = 108

Step-by-step explanation: In this problem, we're given a diagram and

we're asked to find the value of x that would make m ll n.

We can see that the angles that are marked in the diagram

are same-side interior angles since they lie on the same side

of the transversal and they lie on the interior of lines m and n.

Therefore, in order for line m to be parallel to line n,

these angles must be supplementary.

In other words, they must add to 180 degrees.

So we can setup the equation x + 72 = 180.

Subtracting 72 from both sides gives us x = 108.

So the value of x that would make line m ll n is 108.
