Solve the system using elimination

2x+3y=8
5x+6y=17

Answers

Answer 1

Answer:

x=1

Step-by-step explanation:

For this problem, we can choose to eliminate either the x values or the y values.

In this case, it would be easier to do y.

We alter the first equation by multiplying by -2 on both sides.

-4x+-6y=-16

Now, we have the equations

-4x+-6y=-16 and 5x+6y=17.

We can see that there is -6y in one equation and 6y in the other, meaning that if we add both equations together, the ys will cancel each other out because they are opposites.

So let's add the equations.

-4x-6y+5x+6y=-16+17

x=1

The scale factor of triangles ΔRST and ΔUVW is 1.

Option C is the correct answer.

What is a scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object,

We have,

ΔRST and ΔUVW have the same measure of the corresponding sides.

So,

RS/UV = 8/8 = 1

ST/VW = 7/7 = 1

RT/UW = 7/7 = 1

Thus,

The scale factor of ΔRST and ΔUVW is 1.

To determine the break-even point, or the number of units that must be sold so that no profit or loss occurs, an economist uses the formula
Px = Cx + F,
where P is the selling price per unit, x is the number of units that must be sold to break even, C is the cost to make each unit, and F is the fixed cost. Use this equation for the following exercise.

A business analyst has determined that the selling price per unit for a gas barbecue is $300. The cost to make one gas barbecue is $190, and the fixed cost is $27,610. Find the break-even point.

Which unit would you must likely use to measure the capacity of a mug?
A. Teaspoons
B. Quarts
C. Fluid Ounces ?

Answers

Answer:

c

Step-by-step explanation:

Fluid Ounces would be likely to use to measure the capacity of a mug.

The unit to measure the volume of a mug is required.

The best suitable unit is fluid ounces.

Let us convert each unit to liters which will help us compare the units.

[tex]1\ \text{teaspoon}=0.00493\ \text{l}[/tex]

[tex]1\ \text{quart}=0.95\ \text{l}[/tex]

[tex]1\ \text{fluid ounce}=0.0296\ \text{l}[/tex]

A teaspoon is to small to measure a mug's volume, while a quart is too large.

So, the best suitable unit is fluid ounces.

A I used 3.14 for pi which is why I'm a little out.

Step-by-step explanation:

The diagram makes it hard to tell. Where exactly is the arrow pointing?

I think it means the diameter.

r = d/2

r = 4

Volume = 4/3 * pi * r^3

Volume = 4/3 * 3.14 * 4^3

Volume = 4/3 * 3.14 * 64

volume = 4 * 64 * pi / 3

Volume = 256 pi/3 = 267.9

Answer:

solutions: (1, -2), (5, 2)not solutions: (-3, 6), (1, -7)

Step-by-step explanation:

The first inequality describes a line with negative slope and y-intercept -4. The solution space is above that line.

The second inequality describes a line with positive slope and y-intercept +1. The solution space is below that line.

Together, the lines make a sort of X on the graph. The resulting solution space will be in the right-side quadrant of that X. Any sufficiently small y-value for a sufficiently large x-value will be a solution. Any point to the left of x=-4 will not be a solution. Values in each category are listed above and shown on the attached graph.

Because if you do 3.2*10= 32
