THE EQUATION TO THIS PROBLEM IS y=2x+12

Answer:

slope: 2

y intercept: 12

equation: y = 2x + 12

Step-by-step explanation:

Slope is change in y over change of x. You can use any two coordinates from the table, but I will use the first two,

(y1-y2)/(x1-x^2) = (14-12)/(1-0) = 2/1 = 2.

This means that the slope is 2.

Y-intercept is the y value of a coordinate that has the x value of 0. The coordinate (0,12) tells us that 12 is the y-intercept.

Equation: y = mx + b

Plug in the slope and y-intercept into the equation and you will get y = 2x + 12

use reapeted addition and keep adding +$0.50 until you get $4.00 for it to be equal with Jason's total which was $4.00

so it will be at 3 miles.

or just multiply micheals total by 3.:) hope it helped!!

Can someone answer this too?!?!

1/6 plus 2/3 = 5/6 so you do 24 - 5/6 which is 23 1/6

Express your answer as a polynomial in standard form.

Juli2301 [7.4K]

Answer:

(f o g)(x) = -2x² - x + 4

Step-by-step explanation:

f(x) = -x + 6

g(x) = 2x² + x + 2

To find (f o g)(x), you need put g(x) into f(x).

f(x) = -x + 6

(f o g)(x) = -(2x² + x + 2) + 6

(f o g)(x) = -2x² - x - 2 + 6

(f o g)(x) = -2x² - x + 4

For what values of m does the graph of y = 3x2 + 7x + m have two x-intercepts?

frutty [35]

Answer:

m < $\frac{49}{12}$

Step-by-step explanation:

Using the discriminant Δ = b² - 4ac

Given a quadratic equation in standard form, y = ax² + bx + c

Then the value of the discriminant determines the nature of the roots

• For 2 real roots then b² - 4ac > 0

Given

y = 3x² + 7x + m ← in standard form

with a = 3, b = 7 and c = m, then

7² - (4 × 3 × m) > 0

49 - 12m > 0 ( subtract 49 from both sides )

- 12m > - 49

Divide both sides by - 12, reversing the symbol as a result of dividing by a negative quantity.

m < $\frac{49}{12}$
