Hello from MrBillDoesMath!

Answer: -3 and 2

Discussion:

The equation to solve is:

6/m + 2 = (m+3)/(m-1)

Multiple both sides by m * (m-1).

6/m * (m*(m-1)) + 2 m (m-1) = (m+3)/(m-1) * (m(m-1))

Simplify:

6 (m-1) + 2 m (m-1) = (m+3)*m =>

6m -6 + 2m^2 - 2m = m^2 + 3m =>

2m^2 +4m - 6 = m^2 + 3m. Subtract m^2 and 3m from both sides

m^2 + m - 6 = 0. Factor this equation.

(m +3) ( m-2) = 0 so the solution set is -3 and 2

Thank you,

MrB

The graph of $y = ax^2 + bx + c$ is shown below. Find $a \cdot b \cdot c$. (The distance between the grid lines is one unit.)

Savatey [412]

Answer:

$a\cdot b\cdot c=\frac{15}{4}$

Step-by-step explanation:

Vertex is the minimum or maximum point of parabola

Vertex of parabola is (h,k)

Therefore, from given graph (-3,-2) is the lowest point.

Vertex of parabola is at (-3,-2).

Standard equation of parabola

$y-k=a(x-h)^2$

Substitute the values

$y-(-2)=a(x-(-3))^2=a(x+3)^2$

$y+2=a(x+3)^2$

(-1,0) lies on the parabola.

Therefore, it satisfied the equation of parabola.

$0+2=a(-1+3)^2=4a$

$a=2/4=1/2$

Now, using the value of a

$y+2=1/2(x+3)^2=1/2(x^2+6x+9)$

$y+2=\frac{1}{2}x^2+3x+\frac{9}{2}$

$y=\frac{1}{2}x^2+3x+\frac{9}{2}-2$

$y=\frac{1}{2}x^2+3x+\frac{9-4}{2}$

$y=\frac{1}{2}x^2+3x+\frac{5}{2}$

By comparing with

$y=ax^2+bx+c$

We get

$a=\frac{1}{2}, b=3, c=5/2$

$a\cdot b\cdot c=\frac{1}{2}\times 3\times \frac{5}{2}$

$a\cdot b\cdot c=\frac{15}{4}$

When a number is added to 1/5 of itself, the result is 24. The equation that models this problem is n +1/5 n = 24. What is the v

Lady_Fox [76]

For this case we must find the value of n of the following equation:

$n + \frac {1} {5} n = 24$

Taking common factor "n" from the left side of the equation we have:

$n (1+ \frac {1} {5}) = 24\\n \frac {6} {5} = 24$

Multiplying by 5 on both sides of the equation:

$6n = 120$

Dividing between 6 on both sides of the equation:

$n = 20$

Thus, the value of n is 20.

Answer:

$n = 20$

What is solution to this equation 4x=124

kkurt [141]

4x= 124

divide both sides by 4 to get x by itself

4x/4= 124/4

Cross out 4 and 4, divide by 4 and then becomes 1*1*x= x

124/4

12/4= 3

4/4= 1

Answer: x= 31
