How do I divide 12 by 3 and get a mixed number .please help!!!!!!

1 answer:

4 0

Division doesn't always result in a mixed number. And you don't have
a choice . . . either it does or it doesn't.

If you divide 12 by 3, it doesn't. You get just plain 4 with no fraction.

Find the x- and y- intercepts of the line. 2X+3y=-18

Anna71 [15]

To find the x-intercept, plug zero into y and solve for x.

2x+3(0)=-18

2x=-18
/2 /2

x=-9
To solve for the y-intercept, do the same thing, but instead plug zero into the x-intercept to solve for y.

2(0)+3y=-18
3y=-18
/3 /3

y=-6

So, your answer to your question is the y-intercept=-6, and the x-intercept=-9
Hope this helps!:)

$5 PAYPAL + BRAINLIEST TO ANSWER THS

Answer:

Quadratic Equation:

$3x^2=2x +5$

$\text{Standard Form: } 3x^2-2x-5=0$

From the standard form of a Quadratic Function, we get:

$a=3,\:b=-2,\:c=-5$

Discriminant:

$\Delta=\left(-2\right)^2-4\cdot \:3\left(-5\right)$

$\Delta=\left(-2\right)^2+4\cdot \:3\cdot \:5$

$\Delta=64$

From the discriminant, we conclude that the equation will have two real solutions.

State that:

$b^2-4ac$

$b^2-4ac =0:\text{The equation has 1 real solution}$

$b^2-4ac >0:\text{The equation has 2 real solutions}$

By the way, solving the equation given:

$x=\frac{2\pm\sqrt{64}}{2\cdot \:3}$

$x=\frac{2\pm\sqrt{64}}{6}$

$x=\frac{2\pm8}{6}$

$x_{1} =\frac{10}{6}=\frac{5}{3}$

$x_{2}=\frac{-6}{6} =-1$

What values of x make the equation x(squared)+9x-22=0

kkurt [141]

Answer:

$x = 2 \: \: \: \: \: or \: \: \: \: \: x = - 11$

Step-by-step explanation:

${x}^{2} + 9x - 22 = 0 \\ {x}^{2} + 11x - 2x - 22 = 0 \\ x(x + 11) - 2(x + 11) = 0 \\ (x - 2)(x + 11) = 0 \\ x - 2 = 0 \: \: \: \: \: or \: \: \: \: \: x + 11 = 0 \\ x = 2 \: \: \: \: \: or \: \: \: \: \: x = - 11$
