Answer:

C

Step-by-step explanation:

The correct option is C because lines can extend its length in both side infinitely. It contains arrowheads indicating it can extend.

Pls rate.........

A line is an undefined term because it describes something that does not have width or depth. thus, option C is correct answer.

If the ray lies onto the considered line segment(overlapping), then it can be said belonging to the considered line segment.

(line segment has 2 fixed ends, whereas a ray has one end only, other end is not fixed)

A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).

A lines can extend its length in both side infinitely. It contains arrowheads indicating it can extend.

A line is an undefined term because it describes something that does not have width or depth. thus, option C is correct answer.

Step-by-step explanation:

75,000 x 28% ÷ 12

She will budget $225 for her emergency savings for the month of March

We have:

Gross = $75,000 per year.

Payroll deductions = 28%

So, the net pay is:

Net = (1 - 28%) * $75,000

Evaluate

Net = $54000

The net income per month is:

Monthly = $54000/12

Evaluate

Monthly = $4500

5% of her net income goes to emergency.

So, we have:

Emergency = 5% * $4500

Evaluate

Emergency = $225

Hence, she will budget $225 for her emergency savings for the month of March

The specified function's vertex form is [tex]g(x) = 4(x+5)^2 - 100[/tex]

If a quadratic equation is written in the form

[tex]y=a(x-h)^2 + k[/tex]

then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)

If a polynomial p(x) can be written as:

[tex]p(x) = [f(x)]^2[/tex]

where f(x) is also a polynomial, then p(x) is called as perfect square polynomial

For the considered case, the polynomial specified is;

[tex]g(x) = 40x + 4x^2[/tex]

[tex]g(x) = 40x + 4x^2\\g(x) = 4(x^2 + 10) = 4(x^2 + 10 + 25 -25)\\g(x) = 4(x^2 + 10 + 25) - 100 = 4(x+5)^2 - 100\\[/tex]

Thus, the vertex form of the considered polynomial is [tex]g(x) = 4(x+5)^2 - 100[/tex]

Standard form of a quadratic polynomial is [tex]ax^2 + bx + c[/tex]

Thus, we get: the considered polynomial in standard form as:

[tex]g(x) = 4x^2 +40x[/tex]

[tex]g(x) = 40x + 4x^2 \\g(x) = 4x(10 + x)[/tex]

The considered polynomial has only two terms, therefore, its not a trinomial.

Thus,  the specified function's vertex form is [tex]g(x) = 4(x+5)^2 - 100[/tex]

Step-by-step explanation:

The two joggers who are 21 miles apart travel at a speed 8 mph and 6 mph respectively and would meet after one and half hours.

An equation is an expression used to show the relationship between two or more variables and numbers.

Let a represent the speed of the faster jogger and represent the speed of the other jogger. Hence:

a = b + 2 (1)

Also:

In one and half hour (1.5 h):

a = d₁/1.5

d₁ = 1.5a

b = d₂/1.5

d₂ = 1.5b

d₁+ d₂ = 21

1.5a + 1.5b = 21   (2)

From both equation 1 and 2:

a = 8, b = 6

The speed of the joggers is 8 mph and 6 mph respectively.

Answer:

2/3 or -5 is correct for all future users.

Step-by-step explanation:

The roots of the quadratic equations or the values of x are -5 and 2/3.

A quadratic equation is an algebraic equation of degree two. An algebraic equation of degree n has exactly n number of roots.

Given a quadratic equation 3x² + 13x = 10 which can be written as,

3x² + 13x - 10 = 0.

Now two numbers that add to 13 and multiplied to -30 are 15 and - 2.

3x² + 15x - 2x - 10 = 0.

3x(x + 5) - 2(x + 5) = 0.

(x+5)(3x-2) = 0.

x + 5 = 0 OR 3x -2 = 0.

x = -5 OR x = 2/3.

Answer:

9.75$

Step-by-step explanation:

Answer:

9.75$

Step-by-step explanation:

The original price of the shirt is $15, and it's on sale for 35% off. What is the item's sale price?

First, convert the 35% to a real mathematical number. For percents, this is always done by dividing the 35% by 100%, or 35% / 100% = 0.350.

Second, find out what 35% of $15 is. This is the amount of the sale discount. This is always found by multiplying 0.350 by the item's cost $15, like this:

0.350 x $15 = $ 5.25.

So for this sale, you'll save $ 5.25 on this item.

This means, the cost of the item to you is

$15 - $ 5.25 = $ 9.75.

We can transform the mathematical sentence into the equation:

(2/3)*x - (2*y)^2 = 43

Here we have the sentence:

" Two thirds of a number decreased by the product of a number and two, squared, is 43"

First, we can define x as "the number"

Then:

" Two thirds of a number..." is:

(2/3)*x

Now we add the next part:

"... decreased by the product of a number and two, squared, is 43"

Assuming that this is another number, let's call it y, we have:

(2/3)*x - (2*y)^2 = 43

This is our two-variable equation.

Answer:

185 children and 35 adults

Step-by-step explanation:

first equation: 6x+4y=1250

second equation: x+y=220

work:

6x+4y=1250 (-1)

x+y=220 (6) we eliminate x, that's why I multiply each term by 6 and -1

-6x-4y=-1250

6x+6y=1320

2y=70

2y/2=70/2

y=35 (I used y for adults)

x+35=220
