Write the equation for 5x + 2y = 3 in slope-intercept form. 11

Nastasia [14]

5x+2y=3
-5x on both sides
2y=3-5x
divide by 2 on both sides
y=3/2-5/2x
rewrite in order (optional depending on teacher)
y=-5/2x+3/2

26 - (2c + 4) = 2(C+6) +C what is c

Zigmanuir [339]

Answer:

c = 2

Step-by-step explanation:

26 - (2c + 4) = 2(c+6) + c

26 - 2c + 4 = 2c + 12 + c

26 - 4 - 12 = 2c + 2c + c

10 = 5c

2 = c

An equation in the form ax2+bx+c=0 is solved by the quadratic formula. The solution to the equation is shown below.x=−7±√ "572"

jolli1 [7]

Answer:

B: a = 1, b= 7, c = -2

Step-by-step explanation:

Quadratic Formula

$x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when}\:ax^2+bx+c=0$

Given:

$x=\dfrac{-7\pm\sqrt{57}}{2}$

Comparing the terms of the given x-value with those of the quadratic formula:

$\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}=\dfrac{-7\pm\sqrt{57}}{2}$

Therefore:

$2a=2 \implies a=1$
$b = 7$
$b^2-4ac=57$

Using the found values of a and b to solve for c:

$\implies b^2-4ac=57$

$\implies (7)^2-4(1)c=57$

$\implies 49-4c=57$

$\implies -4c=57-49$

$\implies -4c=8$

$\implies c=-2$

In summary: a = 1, b = 7, c = -2

$\implies x^2+7x-2=0$

Therefore, option B is the correct solution.
