In each part that​ follows, you are given an equation of a line and a point. Find the equation of the line through the given poi
Semmy [17]

Answer:

a) y=-\frac{1}{9}x

b)y-2=-\frac{1}{3} (x-1)

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.

Point slope:y-y_1=m(x-x_1)

a) m\neq 9 in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is m=-\frac{1}{9}.

We will substitute m=-\frac{1}{9} and x_1=0\\y_1=0.

y-0=-\frac{1}{9} (x-0)

This simplifies to:

y=-\frac{1}{9}x

b) The equation y=3x+4 follows y=mx+b. For the perpendicular line, m\neq 3. We will need to change it into its negative reciprocal which is m=-\frac{1}{3}.

We will substitute m=-\frac{1}{3} and x_1=1\\y_1=2.

y-2=-\frac{1}{3} (x-1)

Liono4ka [1.6K]

Answer:

4829

Step-by-step explanation:

If the first digit is half of the second, that means the second is 2 times the first

So let's solve this algebraically...

The first digit could be called <em>a</em>

The second digit would have to be 2 times a (2a)

We can call the 3rd digit b

Since the sum of the second and third digit is 10, the equation would be this..

2x + b = 10, which is the same as b = 10 - 2x

The fourth digit is this equation

2x + 1

So the four digits are...

x, 2x, 10-2x, 2x+1

They are all equal to 23, which means...

x + 2x + 10-2x + 2x +1 = 23

After simplifying...

3x + 11 = 23

3x = 23 - 11

Which means...

3x = 12, x = 4

After you plug all that back into the prior equation you should get

first digit = 4 second digit = 8 third digit = 2 fourth digit = 9

Thank me later :)
