Answer:
q = 4
Step-by-step explanation:
Step 1: Set up the equation
The system of equations can be solved algebraically by substitution or elimination.For substitution, solve one of the equations for m and plug it into the other equation in order to solve for q.For elimination, cancel the m terms in order to solve for q.Step 2: Solve for q
Substitution:2m - 5q = 84m + 2q = 644m = 64 - 2qm = [tex]\frac{64-2q}{2}[/tex]m = 16 - [tex]\frac{1}{2}[/tex]q2(16 - [tex]\frac{1}{2}[/tex]q) - 5q = 832 - q - 5q = 8-6q = -24q = 4Elimination:2m - 5q = 8 (multiply whole equation by -2 in order cancel m terms)4m + 2q = 64-2(2m - 5q = 8)-4m + 10q = -164m + 2q = 6412q = 48q = 4
Let's find the slope of the line containing the points (-4,1) and (2, 3).
Answer:
1/3
Step-by-step explanation:
Compute the slope of the line through the following points:
p_1 = (-4, 1) and p_2 = (2, 3)
The slope of the line through (x_1, y_1) and (x_2, y_2) is:
(y_2 - y_1)/(x_2 - x_1)
Substitute (x_1, y_1) = (-4, 1) and (x_2, y_2) = (2, 3):
= (3 - 1)/(2 - -4)
3 - 1 = 2:
= 2/(2 - -4)
-(-4) = 4:
= 2/(2 + 4)
2 + 4 = 6:
= 2/6
The gcd of 2 and 6 is 2, so 2/6 = (2×1)/(2×3) = 2/2×1/3 = 1/3:

The inequality in the slope-intercept form is y≥(3x/7)+3 when the graph is in of a linear inequality.
What is meant by slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844)[2] and Todhunter's formulations of the equation for a straight line as y = mx + b and y = mx + c, respectively.
Let the linear equation be
y=m x +c
From the graph the lines are passing through the points (-7,0), (0,3)
Slope m =(3-0)/(0+7)
m=3/7
c=y-intercept
Therefore, c=3
Substitute the values in the above equation.
y=(-3/7)x+3
7y=3x+21
But, here we need to use the inequality which satisfies the shaded region.
Let us consider the point (1,2)
7(2)=3(1)+21
14=24 (But 14≠24)
Therefore, 14≥24
So, we have to use ≥ sign
7y≥3x+21
y≥(3x/7)+3
The inequality in the slope-intercept form is,
y≥(3x/7)+3

One of the number i a multiple of 9
The other four number are equal. Work out the reult when the five number are multiplied. Optional working
The multiplication of 5 whole numbers is 16875
Given that
5 positive whole numbers add up to 47
we solve these by using system of equation
let 5 whole numbers be p, q, r, s and t
equation is: p + q + r + s + t = 47
one of the number is a multiple of 9 the other four numbers are equal
let p be the multiple of 9
equation is: p + q + q + q = 47
p + 4q = 47
let's try trial and error method q and p are whole numbers, they cannot be decimal
let p = 9
9 + 4q = 47
4q = 47-9
4q = 38
q = 9.5 it is not whole number, so this is not the number
let p= 18
18 + 4q = 47
4q = 47-18
4q = 29
q = 7.25 it is not whole number, so this is not the number
let p = 27
27 + 4q = 47
4q = 47 -27

If an athlete runs at a rate of 309 yd. /min. If one lap is 315 yard athlete then athlete covers 18.63 laps in 19 minutes
What is a conversion factor?
A fraction that is equal to "1" is a conversion factor. The numerator and denominator are the same amount, but they are expressed in different units. It is used to change a number's unit of measurement. In order to do that, multiply the initial number by the fraction equal to "1"; this maintains the original number's value but modifies the units.
An athlete run at a rate of 309 yds. /min.
If one lap is 315 yard
Then total number of yards covered by the athlete is 5871.
I.e. 309 x 19 = 5871.
So total laps covered by the athlete in 19 minutes is

1. $5
2. $2 for each mile
3.equation, in slope-intercept form, that relates the cost compared to the miles traveled for a Green Caby=x+5
What is an explanation of the slope-intercept form?
Simply put, the slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible. This form is frequently known as the y = mx + b form.
1. The graph shows that the Green Cab will cost you $5 for a distance of 0 miles.
2. According to the graph, $1 is spent for every mile traveled.
3. Because y increases by the same amount for every 1 increase in x, the slope is 1.
The slope intercept form is y=mx+b.
m=slope
intercept b=y
Since we are aware that the slope is 1, we can enter it.
y=1x+b
=y=x+b
By looking at the graph and calculating what y equals when x is 0, we may get the y intercept.
It is the y intercept (0,5)
So that the equation is in slope intercept form, we may enter that.

A = Σ A' + Σ A''
Where:
A - Total area, in square feet.A' - Total area of the two rectangles, in square feet.A'' - Total area of the two right triangles, in square feet.The area formulas for right triangles and rectangles:

A = 0.5 · b · h
Where:
b - Base, in feet.h - Height, in feet.Rectangles
A = b · h
Now we proceed to calculate the area of the composite figure:
A = 0.5 · (13 ft) · (20 ft) + 0.5 · (11 ft) · (4 ft) + (4 ft) · (8 ft) + (7 ft) · (3 ft)
