Answer:

4, -26/3

Step-by-step explanation:

The length of the diagonal of the container is the square root of length squared plus width squared plus height squared. This is then\sqrt{x^{2}+(x+8)^{2} +(x-1)^{2}} = 13, solving, we get x = 4, or x = -26/3

Write an equation of the line that is perpendicular to 2x + 4y = 6 and passes through the point (6, 4) ). es A ) y = 2x + 4 B) y
netineya [11]

Answer:

B - y = 2x - 8

Step-by-step explanation:

Step 1: find slope

2x + 4y = 6

4y = -2x + 6

Make y the subject of the formula

y =( -2x + 6)/4

We can separate to get the slope

y = -2x/4 + 6/4

y = -x/2 + 3/2

Slope m = -1/2

Step 2: using a point slope form equation

y - y1 = m ( x - x1)

Note: if two lines are perpendicular to the other, it is always a negative reciprocal of each other

ie m = 2

Substitute m into the equation

y - y1 = 2(x - x1)

Step 3: sub the point

( 6 , 4)

x1 = 6

y1 = 4

y - 4 = 2( x - 6)

Step 4 : using a slope intercept form equation

Open the bracket

y - 4 = 2x - 12

y = 2x - 12 + 4

y = 2x - 8

The equation of a line is

y = 2x - 8

SAT practice: Find the solution (x,y) to the system of equations below, what is the value of x-y (show work)
Zanzabum

7x + 3y = 8 \\ y = 2x -  \frac{5}{3}

Substitute the given value of x into the first equation

7x + 3( 2x-  \frac{5}{3} ) = 8

To solve for x distribute 3 though the parentheses

7x + 6x - 5 = 8

Collect like terms

13x - 5 = 8

Move the constant to the right-hand side and change its sign

13x = 8 + 5

Add the numbers

13x = 13

Divide both sides of the equation by 13

x = 1

Now, Substitute the given value of x into the second equation

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

Plug in the value of x in the equation i.e. 1

y = 2 \times 1 -  \frac{5}{3}

Any number multiplied by 1 results in number itself

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

Calculate the difference

y =  \frac{1}{3}

The possible solution of the system is the ordered pair (x,y)

(x,y)=(1, \frac{1}{3} )
