D. 24 1/2​

Answer:

A linear equation is a fancy term for a straight line, which can be created by joining 2 points.

A point can be defined by (x, y), where x and y are the horizontal distance and the vertical distance respectively from point (0,0) (called the origin).

There are 3 ways to define a line:

(1) The slope-intercept form

y = mx + b, in which m is the slope, b is the y-intercept, where the line crosses the vertical axis at (0, b). If values of m and b are given, you can substitute and write the equation right away.

The slope, m, is calculated by rise (vertical difference between 2 points on the line) divided by run (horizontal difference between the 2 points on the line)

Step-by-step explanation:

or example, if 2 points on the line are

(x1, y1) and (x2, y2)

Then slope = (y1– y2)/(x1 — x2)

If m > 0, then the line rises to the right.

If m = 0, then the line is horizontal.

If m < 0, then the line rises to the left.

If the line is in the form x = c, where c is a constant, then the line is vertical.

(2) Point slope form

m = (y — y1)/(x — x1), when (x1, y1) and m are given.

In other words,

m(x — x1) = y — y1

mx — m(x1) = y — y1

y = mx — m(x1) + (y1)

Note that b = -m(x1) + (y1)

(3) linear form

ax + by + c = 0, where a, b, and c are constants.

Answer:

y = 30200

x = -29950

Step-by-step explanation:

1.)

Let x represent children and y for adults.

200x + 450y = 7,600,000

x + y = 250

2.)

200x + 450y = 7,600,000

x + y = 250

-200(x + y = 250)

-200x + -200 = -50000

200x + 450y = 7,600,000

+ -200x + -200 = -50000

——————————————-

250y = 7550000

y = 30200

x + 30200 = 250

x = -29950

Uhm so I don’t know why for children I got a negative number? The wording for this question is very weird.

And the graphing you just do those as m/s -->(M,S)

You can put the value of m or s in the given equation of m and s to obtained the missing value.

The completed table would look like:

[tex]\begin{array}{ccccc}m & 0 & 2 & -2 & 8\\s & 4 & 3 & 5 & 0\end{array}[/tex]

[tex]2m + 4s = 16\\\\ \text{Dividing by 2 on both sides}\\\\ \dfrac{2m + 4s}{2} = \dfrac{16}{2}\\\\ m + 2s = 8[/tex]

Use one of the given value and the equation to find the missing value:

[tex]m + 2s = 8\\ 0 + 2s = 8\\ 2s = 8\\\\ s = \dfrac{8}{2}\\\\ s = 4[/tex]

[tex]m + 2s = 8\\ m + 2 \times 3 = 8\\ m = 8 - 6\\ m = 2[/tex]

[tex]m + 2s = 8\\ -2 + 2s = 8\\ 2s = 10\\ \\ s = \dfrac{10}{2} \\\\ s= 5[/tex]

[tex]m + 2s = 8\\ m + 2 \times 0 = 8\\ m = 8[/tex]

Thus, the completed table would be:

[tex]\begin{array}{ccccc}m & 0 & 2 & -2 & 8\\s & 4 & 3 & 5 & 0\end{array}[/tex]

Tell the relationship between both lines

We start by calculating the slopes (m) of both lines.

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For Line 1:

[tex]m_1 = \frac{-6 - (-3)}{-4 - 2}[/tex]

[tex]m_1 = \frac{-6 +3}{-4 - 2}[/tex]

[tex]m_1 = \frac{-3}{-6}[/tex]

[tex]m_1 = \frac{1}{2}[/tex]

For Line 2:

[tex]m_2 = \frac{-8 - 2}{2 - (-3)}[/tex]

[tex]m_2 = \frac{-8 - 2}{2 +3}[/tex]

[tex]m_2 = \frac{-10}{5}[/tex]

[tex]m_2 = -2[/tex]

The lines are not parallel because [tex]m_1 \ne m_2[/tex]

However, they are perpendicular, because:

[tex]m_1 = -\frac{1}{m_2}[/tex]

To prove this, substitute values for m1 and m2

[tex]\frac{1}{2} = -\frac{1}{-2}[/tex]

[tex]\frac{1}{2} = \frac{1}{2}[/tex] --- Proved

t = [tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex]

now multiply each side by 2 to eliminate denominator

2t = 2 ([tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex])

2t = d + h

Step-by-step explanation:

t1 = d1/v1 , t2 = d2/v2.

d1 = d2 , and v1 = 0.8 v2

t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )

t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25
