So first you have to get 3.4% more vehicles from 975 you do this by multiplying 975 by .034 , which equals 33.15 but we will round to 33 . After that you add 33 to 975 and you get 1,013. Now you have to add 3.4% again because the problem says it happens every year so 1,008 multiplied by .034 equals 34.272 but we will round to 34. So now adding the 34 to 1,008 you get 1,042. The answer is C , 1,042 vehicles.

A 100% increase would be 18 so you just have to divide until you get the number added so from 9 to 13 is a increase of 4 so that would be around 44.44% repeating.

Write an equation of the line that passes through each pair of point y=mx+b
jarptica [38.1K]
y=-\frac{2}{3}x+4

Explanation

Step 1

find the slope

when yo know 2 points of a lines, P1 and P2, you can find the slope by using:

\begin{gathered} \text{slope}=\frac{change\text{ in y}}{\text{change in x}}=\frac{y_2-y_1}{x_2-x_1} \\ \text{where} \\ P1(x_1,y_1) \\ P2(x_2,y_2) \end{gathered}

then, let

P1(6,0)

P2(0,4)

replace

\begin{gathered} \text{slope}=\frac{y_2-y_1}{x_2-x_1} \\ slope=\frac{4-0}{0-6}=\frac{4}{-6}=-\frac{2}{3} \end{gathered}

Step 2

find the equation of the line,

\begin{gathered} y-y_1=slope(x-x_1) \\ \text{replace} \\ y-0=-\frac{2}{3}(x-6) \\ y=-\frac{2}{3}x+\frac{12}{3} \\ y=-\frac{2}{3}x+4 \end{gathered}

so , the equation of the lines is

y=-\frac{2}{3}x+4

where -2/3 is the slope, and 4 is the y-intercept

I hope this helps you

X²-x-12=0<br> Describe the number and types of roots using the discriminant<br> Show steps please
pickupchik [31]

Answer:

2 real roots

Step-by-step explanation:

The discriminant is b^2 -4ac  where ax^2 +bx -c

If b^2 -4ac > 0 we have 2 real roots

b^2 -4ac = 0 we have 1 real root

b^2 -4ac < 0 we have 2 complex roots

x²-x-12=0

a =1 b=-1  c = -12

(-1)^2 - 4(1)*(-12)

1 +48

49 > 0

2 real roots
