1. Identify the midpoints of the points listed below

The answer is 1

Use the discramnt formula

[tex] {b {}^{2} - 4ac } [/tex]

Where a is 81, B is 18, and c is 1

We get

[tex]18 {}^{2} - 4(81)(1)[/tex]

We then get 324-324=0

Which equal 0. Since the discramnt produce 0, the number of solution is one and repeated.

Answer:

g(x) = 2f(x) -------> y-intercept at (0,2)

h(x) = f(x)+2 -------> asymptote of y=2

j(x) = f(x+2) -------> y-intercept at (0,4)

m(x) = function decreases as x increases

From the graph that's given, the correct matching of the functions will be:

Answer:

90 degrees

Step-by-step explanation:

Step 1: State what is known

Notice that the 2 lines cut the square in half and create 4 congruant triangles.  We know a full circle is 360 degrees and the intersection is a perfect circle formed by 4 angles.  We can find the angle AEB by dividing 360 by 4 which gives you 90 degrees

Answer:

Fourth Option

Step-by-step explanation:

The perimeter of a shape is all sides added. So, if you do 2x + 2x + (x+1) + (x+1), you would get 6x+2. To get the answer to the question, you verify to see which one of the options equal to 6x+2.

First option:

2x(x+1) and 2(2x) + 2(x+1). You find what this equals. 2x(x+1) = 2x^2+2x so we can automatically elimate this one.

Second option:

2x(x+1) and 2x+2x+2x+1. Here again you see 2x(x+1) which equals 2x^2+2x and is not correct so we eliminate this.

Third option:

4x(2x+2) and 2x(x+1) + 2x(x+1). Once more you see 2x(x+1) but added to 2x(x+1) which would basically equal 2x^2+2x *2. Therefore, it's not this one.

Fourth option:

6x+2 and 2x+(x+ 1) +2x + (x+ 1). Now this one looks right because we already got 6x+2 and this is the only option that presents that but also because we initially solved 2x + 2x + (x+1) + (x+1) and this equals 2x+(x+ 1) +2x + (x+ 1).

I guess you don't really have to solve each of them you can kinda see and tell that the last one seems right but if you're not sure you should use the process above.

Answer:

Adult tickets cost $80, children ticket cost $40

Step-by-step explanation:

Given data

let the number of adults be x

and the number of children be y

so

x+y= 40-------------1

The adult tickets

cost 14 dollars and the children’s tickets cost 12 dollars.

14x+ 12y=  720-------2

solve 1 and 2

x+y= 40

14x+ 12y=  720

from 1

x= 40-y

put this in 2 in place of x

14(40-y)+12y= 720

560-14y+12y= 720

collect like terms

-2y= 720-560

-2y= 160

y= -160/2

y= -80

put y= 80 in 1

x+80= 40

x= 40-80

x= -40

Hence Adult tickets cost $80, children ticket cost $40

Answer:

At least 7 shirts would need to be sold to cover their costs

Step-by-step explanation:

Cost of producing x t-shirts.

The cost of producing x t-shirts is a flat fee of 35 plus 4.25 per t-shirt. So

[tex]C(x) = 35 + 4.25x[/tex]

Earnings of selling x t-shirts:

Charges $10 per t-shirt, so it earns 10 for each t-shirt it sells.

[tex]E(x) = 10x[/tex]

How many shirts would need to be sold to cover their costs?

To cover the costs, we need that the earnings are equal or higher than the costs. So

[tex]E(x) \geq C(x)[/tex]

[tex]10x \geq 35 + 4.25x[/tex]

[tex]5.75x \geq 35[/tex]

[tex]x \geq \frac{35}{5.75}[/tex]

[tex]x \geq 6.09[/tex]

Since we cannot sell a decimal part of a shirt, at least 7 shirts would need to be sold to cover their costs

Answer:

x = 90

Step-by-step explanation:

A line will ALWAYS equal 180 degrees, so we know that one angle is <90 and we have to find x, which is the other angle of the line.

So, x + 90 = 180

You can either solve the equation for x or you can just subtract 90 from x, which is the easier way.

180 - 90 = 90

So, x = 90

Answer:

10:2, 15:3, 20:4, etc.

Step-by-step explanation:

Well just keep going, they all simplify back to 5:1

The required equivalent ratios are,

[tex]10:2\\15:3\\20:4\\[/tex]

Equivalent ratios are the ratios that are the same when we compare them. Two or more ratios can be compared with each other to check whether they are equivalent or not.

For example, 1:2 and 2:4 are equivalent ratios.

The given ratio is,

[tex]5:1[/tex]

Now, as we know that we can convert the given ratio into fractions.

[tex]\frac{5}{1}[/tex]

Now, for finding the equivalent ratios multiply the same constant in both the numerator and denominator.

So, the required ratios are,

[tex]\frac{5\times2}{1\times 2} =\frac{10}{2}=10:2\\ \frac{5\times3}{1\times 3} =\frac{15}{3}=15:3\\\frac{5\times4}{1\times 4} =\frac{20}{4}=20:4\\[/tex]

And so, on.
