David wants to purchase some pens. The pens he likes cost $2 each, not including tax. This is represented by the graph below.
Notice triangle BAC.
Notice triangle BDE.
Explain how the triangles demonstrate that the rate of change is consistent for number of pens purchased and the cost.
Answers
The rate of change is always the same for a straight line no matter the points used.
The equation of a straight line is given by:
y = mx + b;
where y, x are variables, m is the rate of change and b is the y intercept.
In triangle BAC:
Rate of change = change in y(cost) / change in x(pens) = (6 - 0) / (3 - 0) = 2
In triangle BDE:
Rate of change = change in y(cost) / change in x(pens) = (8 - 0) / (4 - 0) = 2
The rate of change is always the same for a straight line no matter the points used.

Please help me ASAP! Show all your work please.
Answers
If we want the area to be more than 225 sqft, and the width is already established as 25, then we can divide 225 by 25 to see what the minimum would be. 225/25 is 9, so this is the minimum. We want a set of possible lengths though, and as long as the pen is over 225 sqft, it's allowed. Therefore, the answer is [tex]x\geq 9[/tex].

help me with which triangle it is and how do I find x?
Answers
Answer:
isosceles
x=14
Step-by-step explanation:
isosceles because of the two I symbols on the triangle
x+5=2x-9
5+9=2x-x
14=x
Step-by-step explanation:
it's an isosceles triangle,
as an Isosceles triangle have two equal sides so
→ 2x - 9 = x + 5
→ 2x - x = 5 + 9
→ x = 14
therefore, value of x is 14.
2(14) - 9 = 28 - 9 = 19
14 + 5 = 19

What is an equation of the line?A line equation is defined as a linear equation with a degree of one. The line equation has two variables, x and y. The third parameter is the line's slope, which represents the line's elevation.
The following is the general form of the line equation:
y = mx + c
m = slope
c = y-intercept
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
Calculate the slope of the line:-
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \dfrac{ -2 + 1 } { -3 - 5 }[/tex]
[tex]m = \dfrac{1}{8}[/tex]
The y-intercept will be:-
y = mx + c
[tex]-2 = \dfrac{-3}{8} + c[/tex]
[tex]c = \dfrac{-13}{8}[/tex]
The equation can be written as:-
y = mx + c
[tex]y = \dfrac{1}{8} x- \dfrac{13}{8}[/tex]

Which linear inequality is represented by the graph?
y < 3x + 2
y > 3x + 2
y < 1/3x + 2
y > 1/3x + 2
Answers
Answer:
y > 3x + 2
Step-by-step explanation:
Find gradient using given points:
m = gradient
Formula:
m = Δy/Δx
m = 9/3 = 3
So, equation of line will be:
y = 3x + a
a is 2 as the point (0, 2) is on the line, 2 units above origin point
The options remaining are:
y > 3x + 2 and y < 3x + 2
Consider any point in the shaded region and compare the y-value of that point with the y-value at the same value of x along the line, e.g. (0, 3) is within the shaded region, the y-value of the line at x = 0 is 2, i.e. the coordinates are (0, 2)
3 > 2 ∴ the correct inequality is y > 3x + 2

Find X
Brainliest
Answers
Answer:
x = 6.428
Step-by-step explanation:
2(7x-34) = 22
Distribution:
2 times 7x = 14x
2 times -34 = -68
Your equation is now:
14x - 68 = 22
Add 68 on both sides to leave 14x alone
68+22 = 90
You are left with this equation:
14x = 90
Divide by 14 to isolate the x
90/14
x = 6.428 (approximately)
Answer:
The value of x is 45/7.Work:
2(7x - 34) = 22=> 14x - 68 = 22=> 14x = 22 + 68=> 14x = 90=> x = 90/14=> x = 45/7Hence, the value of x is 45/7.

Answers
Answer:
[tex]y = \frac{-3}{4}x + \frac{3}{2}[/tex]
Step-by-step explanation:
Because is a line the equation is of the form
[tex]y = mx + b[/tex]
Since both lines are parallel the slope of both equations are the same
[tex]y = \frac{-3}{2}x + b[/tex]
Now for find the unknow [tex]b[/tex] replace the [tex]x[/tex] and [tex]y[/tex] fo the given point.
[tex]3 = (\frac{3}{4}) 2 + b[/tex]
[tex]3 = \frac{3}{2} + b[/tex]
[tex]3 - \frac{3}{2} = b[/tex]
[tex]\frac{3}{2} = b[/tex]
So the final equation is equal to
[tex]y = \frac{-3}{4}x + \frac{3}{2}[/tex]
