What are the solutions of x^2 = -7x-8

Vilka [71]

$Solution, solve\:for\:x,\:x^2=-7x-8\quad :\quad x=\frac{-7+\sqrt{17}}{2},\:x=\frac{-7-\sqrt{17}}{2}$

$Steps:$

$x^2=-7x-8$

$\mathrm{Add\:}8\mathrm{\:to\:both\:sides},\\x^2+8=-7x-8+8$

$\mathrm{Simplify},\\x^2+8=-7x$

$\mathrm{Add\:}7x\mathrm{\:to\:both\:sides},\\x^2+8+7x=-7x+7x$

$\mathrm{Simplify},\\x^2+7x+8=0$

$Solve\:with\:the\:quadratic\:formula,\\\mathrm{For\:}\quad a=1,\:b=7,\:c=8:\quad x_{1,\:2}=\frac{-7\pm \sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1},\\x=\frac{-7+\sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1}:\quad \frac{-7+\sqrt{17}}{2},\\x=\frac{-7-\sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1}:\quad \frac{-7-\sqrt{17}}{2}$

$\mathrm{The\:final\:solutions\:to\:the\:quadratic\:equation\:are:},\\x=\frac{-7+\sqrt{17}}{2},\:x=\frac{-7-\sqrt{17}}{2}$

$\mathrm{Hope\:This\:Helps!!!}$

Someone please help quickly.......

timurjin [86]

Answer:

(2,-6)

Step-by-step explanation:

The solution set is any point to the left of the line. To find the solution set, test a point like (0,0).

$3(0) + 4(0) \leq -1\\0\leq -1\\False$

This means (0,0) is not in the solution set. The solution set is the region to the left of the line. Any point in this area will be a solution.

the sunshine rental company rents cars for $17 per day plus 50 cents per mole driven the rent me company rents cars for $20 per

forsale [732]

Answer:

21.43 miles

Step-by-step explanation:

Let

x ---> the number of miles

y ---> the total cost of rent a car per day

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

<em>sunshine rental company</em>

The slope is equal to

$m=\$0.50\ per\ mile$

The y-intercept is equal to

$b=\$17$

substitute

$y=0.50x+17$ ----> equation A

<em> rent me company</em>

The slope is equal to

$m=\$0.36\ per\ mile$

The y-intercept is equal to

$b=\$20$

substitute

$y=0.36x+20$ ----> equation B

equate equation A and equation B

$0.50x+17=0.36x+20$

solve for x

$0.50x-0.36x=20-17\\0.14x=3\\x=21.43\ miles$
