Answer:

this might help you :

There are several forms that the equation of a line can take. They may look different, but they all describe the same line--a line can be described by many equations. All (linear) equations describing a particular line, however, are equivalent.

The first of the forms for a linear equation is slope-intercept form. Equations in slope-intercept form look like this:

y = mx + b

where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis.

To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). The y- coordinate is the value of b in the equation.

Finally, write the equation, substituting numerical values in for m and b. Check your equation by picking a point on the line (not the y-intercept) and plugging it in to see if it satisfies the equation.

Example 1: Write an equation of the following line in slope-intercept form:

Graph of a Line

First, pick two points on the line--for example, (2, 1) and (4, 0). Use these points to calculate the slope: m = = = - .

Next, find the y-intercept: (0, 2). Thus, b = 2.

Therefore, the equation for this line is y = - x + 2.

Check using the point (4, 0): 0 = - (4) + 2 ? Yes.

Example 2: Write an equation of the line with slope m = which crosses the y-axis at (0, - ).

y = x -

Example 3: Write an equation of the line with y-intercept 3 that is parallel to the line y = 7x - 9.

Since y = 7x - 9 is in slope-intercept form, its slope is 7.

Since parallel lines have the same slope, the slope of the new line will also be 7. m = 7. b = 3.

Thus, the equation of the line is y = 7x + 3.

Example 4: Write an equation of the line with y-intercept 4 that is perpendicular to the line 3y - x = 9.

The slope of 3y - x = 9 is .

Since the slopes of perpendicular lines are opposite reciprocals, m = - 3. b = 4.

Thus, the equation of the line is y = - 3x + 4.

What is the answer?
Bad White [126]

Answer:

k=3

Step-by-step explanation:

+ we note f(p)= p^{4}+p^{2}  +p -k

+ Because of "p-1 is a factor of f(p)", that means f(p)= (p-1)* g(p)

Then we have f(1)= (1-1)*g(1)= 0* g(1)= 0

+ We replace p=1 in f(p) and we have:

f(1)=0

that means: 1^{4}+1^{2} + 1 - k=0

then 1+1+1-k = 0, 3-k=0 or k=3

Hope that useful for you.

Please help I don't know the median give an answer and explanation
morpeh [17]

Answer:

Median is the middle of the data set. For example this data set is 4, 6, 7, 9, 10. First you take out 4 and 10. The you take out 6 and 9 to get a median of 7. But if there is an even amount of numbers like in this data set, 1, 2, 4, 5. Then you take out 1 and 5 and then find the middle point in between 2 and 4 which is 3.

What are the solutions to the equation x² = 256?
Artyom0805 [142]
X = 16
x = - 16

You could do it this way
x^2 - 256 = 0
(x - 16)(x + 16) = 0
x - 16 = 0
x = 16

x + 16 = 0
x  = - 16

What is simple interest rate if p=$4000,t=2years,and I=$320
PolarNik [594]
I=PRT
R=percetnt in decimal form
x%=x/100

I=320
T=2
P=4000
320=(4000)(x/100)(2)
320=8000(x/100)
320=80x
divide both sides by 80
4=x
answer is 4%
