Answer:

slope = - 9 , y- intercept = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2 - 9x , or

y = - 9x + 2 ← in slope- intercept form

with slope m = - 9 and y- intercept c = 2

R Answer:
Slope is -9
y-intercept is 2
Step-by-step explanation:
y=mx+c
Rearrage your formula,
y=-9x+2

m=slope=-9
y-intercept=c=2

Answer:

The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!

hope this helped!

A new car sells for $25,000. The value of the car decreases by 15% each year. What is the approximate value of the car 5 years a

9966 [12]

$10,000
is the answer because

25,000 * .15 is equal to 3750. which means we would subtract $3750 every year for five years. leaving us with $10,000.

The graph of F(x) shown below resembles the graph of G(x)= x4, but it has

Gemiola [76]

Answer:

x = 0.

Equation:

$g*(x)-(x^4)=0$

Step-by-step explanation:

Step 1:

Pull out like factors:
$gx - x^4 = x * (g - x^3)$

Trying to factor as a Difference of Cubes:

Factoring: $g - x^3$
Theory : A difference of two perfect cubes, a^3 - b^3 can be factored into
(a-b) • (a^2 +ab +b^2)
Proof : (a-b)•(a^2+ab+b^2) =
a^3+a^2b+ab^2-ba^2-b^2a-b^3 =
a^3+(a^2b-ba^2)+(ab^2-b^2a)-b^3 =
a^3+0+0-b^3 =
a^3-b^3
Check : g^1 is not a cube !!
Ruling : Binomial cannot be factored as the difference of two perfect cubes

Equation at end of step 1:

$x * (g - x^3) = 0$

Step 2:

A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

Solve $g - x^3 = 0$
In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
We shall not handle this type of equations at this time.

Solution:

x=0.
