PLEASE HELP<br>L has y-intercept (0,5) and is perpendicular to the line with equation y=1/3x+1

marin [14]

Answer:

y=-3x+5

Explanation:

Given a line L such that:

• L has y-intercept (0,5); and

• L is perpendicular to the line with equation y=(1/3)x+1.

We want to find the equation of the line in the slope-intercept form.

The slope-intercept form of the equation of a straight line is given as:

$\begin{equation} y=mx+b\text{ where }\begin{cases}m={slope} \\ b={y-intercept}\end{cases} \end{equation}$

Comparing the given line with the form above:

$y=\frac{1}{3}x+1\implies Slope,m=\frac{1}{3}$

Next, we find the slope of the perpendicular line L.

• Two lines are perpendicular if the product of their slopes is -1.

Let the slope of L = m1.

Since L and y=(1/3)x+1 are perpendicular, therefore:

$\begin{gathered} m_1\times\frac{1}{3}=-1 \\ \implies Slope\text{ of line L}=-3 \end{gathered}$

The y-intercept of L is at (0,5), therefore:

$y-intercept,b=5$

Substitute the slope, m=-3, and y-intercept, b=5 into the slope-intercept form.

$\begin{gathered} y=mx+b \\ y=-3x+5 \end{gathered}$

The equation of line L is:

$y=-3x+5$

Which graph shows the function f(x)=x with an input of (f(x-3)<br>please help me asap!!

stiks02 [169]

Answer:

The second one would be the correct option.

Step-by-step explanation:

The guy above is wrong, the second one is right, I took the assignment.

The guy above is right for the answer on number eight though because there are two of these types of questions asked on this same assignment. I think he got the two questions mixed up, but for question eight he is right, but for question five the second graph is the correct answer.

Don’t mind the red mark but what’s the difference????

taurus [48]

Answer:

If you solve for a2+b2=c2 you will see

Step-by-step explanation:

1 will be 11.61

2. Will be 7.6

so there will be a 4.01 difference

1. a2+3(2)=12(2)

a2+9=144

then subtract 9 from 144

you get 135

then $\sqrt{x}$ 135

6x+5y=120, 7x+11y=202 solve for x and y

Talja [164]

6x=120-5y -> x=20-5/6*y -> 7(20-5/6*y) + 11y =202 -> 140-35/6*y + 11y = 202 -> 140+31/6*y=202 -> 31/6*y = 62 -> y = 12.
