To find the volume for a cube you need to do length x width x height. make sure you put it as cm3 because it’s volume. hope it helps?

If f(x) = g(x), then what does 7x - 12 = -3x + 10?

Bumek [7]

Answer:

x = 2.2

Step-by-step explanation:

Comment

f(x) = g(x) I don't think has any meaning for this question. I will just solve the equation.

Solution

7x - 12 = - 3x + 10 Add 3x to both sides

7x + 3x -12 = - 3x + 3x +10 Combine

10x - 12 = 10 Add 12 to both sides

10x -12 + 12 = 10 + 12 Combine

10x = 22 Divide by 10

10x/10 = 22/10

x = 2.2

What is an equation of a line which passes through (6,9) and is perpendicular to the line whose equation is 4x − 6y = 15?

Svetllana [295]

Given:

The equation of the line passes through the point (6,9) and is perpendicular to the line whose equation is $4 x-6 y=15$

We need to determine the equation of the line.

Slope:

Let us convert the equation to slope - intercept form.

$-6 y=15-4x$

$y=\frac{2}{3}x-\frac{5}{2}$

From the above equation, the slope is $m_1=\frac{2}{3}$

Since, the lines are perpendicular, the slope of the line can be determined using the formula,

$m_1 \cdot m_2=-1$

$\frac{2}{3} \cdot m_2=-1$

$m_2=-\frac{3}{2}$

Therefore, the slope of the equation is $m=-\frac{3}{2}$

Equation of the line:

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Substituting the point (6,9) and the slope $m=-\frac{3}{2}$ in the above formula, we get;

$y-9=-\frac{3}{2}(x-6)$

Simplifying the terms, we get;

$2(y-9)=-3(x-6)$

$2y-18=-3x+18$

$3x+2y=36$

Thus, the equation of the line is $3x+2y=36$

Scott is four more than double the age of Todd. Scott is 56. What is Todd's age?

SSSSS [86.1K]

Answer: 26 years old

Step-by-step explanation:

Since Scott is four more than double the age of Todd, start by taking away four from Scott's age.

56-4=52

Then take half of that because that would be double of Todd's age

52/2=26

Todd is 26 years old.

You are considering a 5/1 ARM. What does the 5 represent?

umka21 [38]

The 5 is the number of years that the interest rate is fixed (at the initial amount set when you sign the mortgage contract)

The 1 represents the idea that the interest rate will change every year after the initial 5 years are up.
