PLEASE HELP 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:

$y=-3x+5$

Brad has already cycled 28 kilometers this year, plus he plans to cycle 1 kilometer during each trip to work. After 21 trips to

zepelin [54]

Answer:

49 kilometers

Step-by-step explanation:

Since he cycles 1 km for each trip, he will have cycled 21 km after 21 trips.

Add this to his existing amount of km:

28 + 21

= 49

So, he will have cycled a total of 49 kilometers

What is the product of 3y product of (3y^)(274)

Dima020 [189]

3y^-4 × (2y^-4) = 6y^-8

= 6/1/y^8

= 6/y^8

.................................................

1) When x^1 multiply with x^2, 1 will add to 2 and become 3

= x^3

2) y^-1 = 1/y

3^-2 = 1/3^2 = 1/9

5^-2 = 1/5^2 = 1/25

Answer:

Step-by-step explanation

Car A started 10 miles east of Johnstown based on the fact he traveled 90 miles in 2 hours but was 100 away from Johnstown

Car B started 20 miles away, so that mean Car B was 10 more miles east than Car A when they started.
