Solve the equation:
x^2=-36 (picture)

Answers

Answer 1

Answer:

This equation is not possible. All numbers that are squared end up as positive. -6^2 still equals 36 as well as 6^2. Hope this helped!

Write the equation of the line that it is parallel to y=2x+1 and passes though the solution of the following systems of equations :3x-2y=10

Answers

The required equation of a line is y = 2x - 11

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The given line,
y = 2x + 1
The slope of the equation is m = 2

Now the point is required,
3x-2y=10 - - - - - -(1)

x+y=5
x = 5 - y - - - - -(2)
putting x in equation 1
3(5 - y) - 2y = 10
15 - 3y - 2y = 10
-5y = -5
y = 1
Now
x = 5 - y
x = 5 + 1
x = 6
Points are (6, 1)
Equation of line is given by,
y - 1 = m (x - 6 )
y - 1 = 2 (x - 6 )
y = 2x -12 + 1
y = 2x - 11

Thus, the required equation of line is y = 2x - 11

well, keeping in mind that parallel lines have the same exact slope, hmmmmm

$\bf y = \stackrel{\stackrel{m}{\downarrow }}{2}x+1\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\n \cline{1-1} \n y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \n\n \cline{1-1} \end{array}$

alrite, so we know the slope has to be 2 then hmmm let's check the point it runs through

$\bf \begin{cases} 3x-2y=&10\n\n x+y=&5\n \qquad y=&5-x \end{cases} \n\n\n \stackrel{\textit{substituting \underline{y} on the 1st equation}}{3x-2(5-x)=10}\implies 3x-10+2x=10\implies 5x-10=10 \n\n\n 5x=20\implies x=\cfrac{20}{5}\implies \blacktriangleright x = 4 \blacktriangleleft \n\n\n \stackrel{\textit{since we know that}}{y = 5-x}\implies y=5-4\implies \blacktriangleright y = 1 \blacktriangleleft$

so, we're really looking for the equation of a line whose slope is 2 and runs through (4,1)

$\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{1})~\hspace{10em} \stackrel{slope}{m}\implies 2 \n\n\n \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\n \cline{1-1} \n y-y_1=m(x-x_1) \n\n \cline{1-1} \end{array}\implies y-\stackrel{y_1}{1}=\stackrel{m}{2}(x-\stackrel{x_1}{4}) \n\n\n y-1=2x-8\implies y=2x-7$

Write the equation of the line passing through (7,-4) and (-1,2) in slope intecept form

Answers

Answer: y = $(-3x)/(4)$ + $(5)/(4)$

Step-by-step explanation:

Using the formula for finding equation of a line :

$(y_(2) - y_(1) )/(x_(2)- x_(1))$ = $(y - y_(1) )/(x - x_(1) )$

From the question:

X1 = 7

X2 = -1

Y1 = -4

Y2 = 2

Substituting into the formula , we have

$(2 - (-4))/(-1 - 7)$ = $(y - (-4))/(x - 7)$

⇒ $(6)/(-8)$ = $(y+4)/(x - 7)$

$(-3)/(4)$ = $(y+4)/(x - 7)$

4( y + 4) = -3 ( x - 7)

4y + 16 = -3x + 21

4y = - 3x + 21 - 16

4y = - 3x + 5

y = -3x/4 + 5/4

Answer:

y=-3/4x+5/4

A.2.5x10^6

B. 0.25x10^18

C.2.5x10^17

D.0.25x10^7

Answers

so (2 times 10^21)/(8 times 10^3)
using the associative property
exg
xy/zt=y/z times x/t so

(2 times 10^21)/(8 times 10^3)=2/8 times (10^21)/(10^3)
2/8=1/4=0.25

when dividing exponents, just subtract the bottom number from the top number exg
10^21/10^3=10^(21-3)=10^18

so the answer is 0.25 times 10^18, but

scientific notation is
(a number >1 and <10) times 10^x

so 0.25 times 10=2.5 and 2.5>1 and <10 so this should work

0.25 times 10^18=2.5 times 10^17 ( we just took the ten from the 18)

so the answer is 2.5 times 10^17 or C
