Answer:
Green line: y = 5x + 2
Red line: y = 3x + 3
Purple line: y = 2x + 3
Step-by-step explanation:
1) All the given equations are in slope-intercept form, or [tex]y = mx + b[/tex] format. When an equation is written in this form, the constant on the right side of the equation, or the [tex]b[/tex], represents the y-intercept. The y-intercept is the point at which the line crosses the y-axis.
Knowing this, the y-intercept of [tex]y = 5x + 2[/tex] must be (0,2). The only graph in which the line crosses the y-axis at the point (0,2) is the one with the green line, thus the graph of [tex]y = 5x + 2[/tex] is the green one.
2) Now, since the other two equations share the same y-intercept, we have two graphs left. We can find out which graph belongs to which equation by taking a look at the slope of the line. The number in place of [tex]m[/tex], or the coefficient of the x-term in an equation in slope-intercept format represents the slope. Thus, the slope of [tex]y = 3x +3[/tex] is 3 and the slope of [tex]y = 2x + 3[/tex] is 2.
Now, find the slope of one of the lines in the graphs. To do so, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of two points on the chosen line into the formula in order to figure out the line's slope. I chose to find the slope of the red line, using the points (0,3) and (-1,0):
[tex]m = \frac{(0)-(3)}{(-1)-(0)} \\m = \frac{0-3}{-1-0}\\m = \frac{-3}{-1} \\m = 3[/tex]
So, the slope of the red line is 3. Its equation must be [tex]y = 3x + 3[/tex] since it has the matching slope. By process of elimination, the purple line must have the equation of [tex]y = 2x + 3[/tex].
The Matching is:
Green line: y = 5x + 2Red line: y = 3x + 3Purple line: y = 2x + 3What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We know the slope- intercept form
y= mx+ b
where m is the slope.
For y= 5x+ 2 the slope is 5.
and, for y= 3x+ 3 the slope is 3.
and, for y= 2x+ 3 the slope is 2.
For Graph 1, the slope is 5/1= 5
and, For Graph 2, the slope is 6/2= 3
and, For Graph 3, the slope is 6/3 = 2

To investigate housing needs in the future, a town planning committee
created a model to help predict the growth of the population of the town. The
data are shown in the table.
Answer:
P(t) = 5.24(1.030)^t
Step-by-step explanation:
The model for P(t) , the population of the town, t years after 1985, best fits the data is option C. P(t) = 5.35 (1.029)^t.
What is Population Growth?Population growth is defined as the increase in the number of people which is calculated using population growth rate.
Population growth is an exponential function.
So, the function will be of the form,
P(t) = a (b)^t
Initial population is the population in 1985.
P(0) = a (b)⁰ = 5.35
⇒ a × 1 = 5.35 (Since any number raised to 0 is 1)
⇒ a = 5.35
Population in 1990, that is after 5 years is,
P(5) = a (b)⁵ = 6.01
⇒ 5.35 (b)⁵ = 6.01
⇒ (b)⁵ = 1.123
⇒ b = 1.024
So the function which best models is P(t) = 5.35 (1.029)^t.
Hence the function is C. P(t) = 5.35 (1.029)^t.

3x(x + 4) – 12(x + 4)
Answer:
3x^{2}+12x-12x-48
3x^{2}-48
Step-by-step explanation:
I hope this answer has helped you
The given factor (3x – 12)(x + 4) is not equivalent to the 3(x2 – 8x + 16) hence, correct option is (A).
What is an algebraic factor?An algebraic factor is the multiplication of two algebraic terms.
That term could be in form of summation multiplication or in subtraction.
The root of the quadratic equation formed by the algebraic factor is always real.
If we divide algebraic factor by a factor which is available inside then the remainder after the division will be zero.
Given that equation
(3x – 12)(x + 4)
⇒ 3x² + 12x - 12x - 48
⇒ 3x² - 48.
Now by option cross-checking
In option (A)
3(x² – 8x + 16)
⇒ 3x² - 24x + 48 which is not equal to the (3x – 12)(x + 4).
Hence correct option will be 3x² - 24x + 48.

Would you rather, $20 off your entire purchase or 20% off your entire purchase?
(I need at least 2 good reasons why, please help!) < 3
Answer:
i personally would much rather have $20 off, because as the price goes up the less money you get off of the total price. but with $20 off, youre automatically getting $20 off. if you were to get %20 off of something that is $50, youd only get about $10 off, but if you used the $20 off coupon, you would get $20. which would be much better. so instead of partially getting some of it off, you can get a much larger amount off
