Answer: y=-4x+1

Step-by-step explanation:

The slope-intercept form of a line is y=mx+b. Therefore, y needs to be on one side of the equation, and the x term and constant need to be on the other. Rearrange the equation to make this true:

4x+y=1

(4x+y)-4x=1-4x

y=1-4x

y=-4x+1

A student solves the following equation and

Phoenix [80]

Answer:

Since the equation is undefined for -2

Therefore, NO SOLUTION for the given equation.

Step-by-step explanation:

Considering the expression

$\frac{3}{a+2}-6\cdot \frac{a}{-4+a^2}=\frac{1}{a-2}$

$\frac{3}{a+2}-\frac{6a}{-4+a^2}=\frac{1}{a-2}$

$\mathrm{Find\:Least\:Common\:Multiplier\:of\:}a+2,\:-4+a^2,\:a-2:\quad \left(a+2\right)\left(a-2\right)$

$\mathrm{Multiply\:by\:LCM=}\left(a+2\right)\left(a-2\right)$

$\frac{3}{a+2}\left(a+2\right)\left(a-2\right)-\frac{6a}{-4+a^2}\left(a+2\right)\left(a-2\right)=\frac{1}{a-2}\left(a+2\right)\left(a-2\right)$

$\frac{3}{a+2}\left(a+2\right)\left(a-2\right):\quad 3\left(a-2\right)$

$-\frac{6a}{-4+a^2}\left(a+2\right)\left(a-2\right):\quad -6a$

$\frac{1}{a-2}\left(a+2\right)\left(a-2\right):\quad a+2$

so equation becomes

$3\left(a-2\right)-6a=a+2$

$-3a-6=a+2$

$-3a-6+6=a+2+6$

$-4a=8$

$\mathrm{Divide\:both\:sides\:by\:}-4$

$\frac{-4a}{-4}=\frac{8}{-4}$

$a=-2$

$\mathrm{Verify\:Solutions}$

$\mathrm{Take\:the\:denominator\left(s\right)\:of\:}\frac{3}{a+2}-6\frac{a}{-4+a^2}-\frac{1}{a-2}\mathrm{\:and\:compare\:to\:zero}$

$\mathrm{Solve\:}\:a+2=0:\quad a=-2$

$\mathrm{Solve\:}\:-4+a^2=0:\quad a=2,\:a=-2$

$\mathrm{Solve\:}\:a-2=0:\quad a=2$

So the following points are undefined

$a=-2,\:a=2$

Since the equation is undefined for -2

Therefore, NO SOLUTION for the given equation.

Find y for x= 1,2,3,and 4<br>y=2x y=3x+1 y=x-5 y=-5x+6

Alenkasestr [34]

Like I said, just use the formulas
y=2x is 2,4,6,8
y=3x+1 is 4,7,10,13
y=x-5 is -4,-3,-2,-1
y=5x+6 is 11,16,21,26
Wow I just noticed these are all patterns...

3x + 5 = 45° + x

stira [4]

Answer:

3x + 5 = 45° + x

In here we can fine like terms by putting the unknown terms together and the whole numbers together example:

3x - x = 45 - 5

After that you can get the value of x

So,

2x = 40

x = 20

For an independent-measures ANOVA comparing two treatments with a sample of n = 10 in each treatment, what is the critical value

trapecia [35]

Answer:

critical value is 4.41

Step-by-step explanation:

Given data

n = 10

α = .05

to find out

the critical value

solution

first we calculate degree of freedom i.e

degree of freedom = n -1

degree of freedom = 10 - 1

degree of freedom = 9

and

degree of freedom 2 =( n -1 ) 2

degree of freedom 2 =( 10 -1 ) 2

degree of freedom 2 = 18

so for degree of freedom 9 and degree of freedom 2 is 18 and α = .05

critical value is 4.41
