Answer:

It's a) y = 1/3x

Step-by-step explanation:

If you plug in the y and x into the problem, for example, 27y

27 = 1/3 times 9

if you multiply 9 and 1/3, you get 27

so it's a)

Answer:

x=10ft

Step-by-step explanation:

Hey,

Since, the total height is 26, you add up the individual heights listed on the sides because they have to add up to 26.

So,

x+x+6=26 (From here it is basic algebra where you solve for x)

2x+6=26 (add the two x variables together)

2x=26-6 (subtract the 6)

2x=20 (divide by 2)

x=10 ft

The answer makes sense too because the line segments are larger than the segment 6 which was given.

Through (2,-2) parallel to y= -1/2x+5

Rzqust [24]

The equation of line passing through (2, -2) and parallel to $y = \frac{-1}{2}x+5$ is $y = \frac{-x}{2}-1$

Solution:

We have to find the equation of line passing through (2, -2) and parallel to $y = \frac{-1}{2}x+5$

The equation of line in slope intercept form is given as:

y = mx + c ------- eqn 1

Where "m" is the slope of line and "c" is the y-intercept

On comparing the given equation of line $y = \frac{-1}{2}x+5$ with eqn 1,

$m = \frac{-1}{2}$

We know that slope of a line and slope of line parallel to it is always equal

Therefore, slope of line parallel to given line is also $m = \frac{-1}{2}$

Substitute (x, y) = (2, -2) and $m = \frac{-1}{2}$ in eqn 1

$-2=\frac{-1}{2}(2)+c\\\\-2 = -1+c\\\\c = -2+1\\\\c = -1$

Substitute c = -1 and $m = \frac{-1}{2}$ in eqn 1

$y = \frac{-1}{2}x -1\\\\y = \frac{-x}{2}-1$

Thus equation of line parallel to given line is found
