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:

$y=-3x+5$

20 POINTS!! What would be the first step to solve this equation?

Anettt [7]

Answer:

C. Add 13 to both sides of the equation.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Add 13 to both sides of the equation:

m - 13 = 24

m - 13 (+13) = 24 (+13)

m = 24 + 13

m = 37

Factor –8x3 – 2x2 – 12x – 3 by grouping. What is the resulting expression?

xenn [34]

Easier if you first factor out the " - " sign. Then you have:

–8x3 – 2x2 – 12x – 3 = -1(<span>8x3 + 2x2 + 12x +3).
</span>
Start with 12 + 3. This factors to 3(4x+1). Next, focus on 8x^3+2x^2. This factors to 2x^2*(4x+1). So, the binomial factor 4x+1 is common to the first two terms and the second two terms. We get: (4x+1) ( 2x^2 + 3).

Now put the "-" sign back in, and we get - (4x+1) ( 2x^2 + 3) (answer)

Please note: Use "^" to denote exponentiation. 2x2 is meaningless; it should be 2x^2.

If 40%of an amount is $24, calculate 100%

Andreas93 [3]

Hey!!

here is your answer >>>

Let's take the total amount as 'X'

Then,

(40/100)X = 24

2x /5 = 24

x = (24*5)/2

x = 12*5

x = 60!.

100% is 60

Hope my answer helps!
