The equation of line CD is Y=3X -3. Write an equation of a line perpendicular to line CD in slope intercept form that contains p
OLga [1]
(I'm learning this right now!)

y = 3x - 3
If a line is perpendicular to another line, they have negative reciprocal slopes.
So you would use the slope -1/3.

Use y - y₁ = m(x - x₁) to get an equation in slope intercept form.
Plug the numbers in.

y - 1 = -1/3(x - 3)
y - 1 = -1/3x + 1
y = -1/3x + 2

An equation of a line perpendicular to line CD is y = -1/3x + 2.

What is the solution to the equation 6Y -2(Y + 1) = 3(Y - 2) +6?
Andrej [43]

Answer:

Y =2

Step-by-step explanation:

6Y -2(Y + 1) = 3(Y - 2) +6

Distribute

6Y -2Y -2 = 3Y -6 +6

4Y -2 = 3Y

Subtract 4Y from each side

4Y - 4Y -2 = 3Y-4Y

-2 = -Y

Multiply each side by -1

2 = Y

What is this plzz need help for math homework it is very hard
evablogger [386]
I believe the correct answer is “a5+2” or, like the question says to write it, “7 L(centimeters.)” this is because using the normal steps for equations, you add up how many “a”s you have total. Then you combine “-1 and +3”, which gives you positive 2. Then you add 5+2 which gives you 7. Hope this helped! :) please mark as Brainliest if the answer is correct!

There is 3/4 pound of cream in a containwr. Julian will use 3/8 pound of cream to make crème brûlée. What fraction of a pound of
Ksivusya [100]

Answer:

\frac{3}{8}\ pound of cream will remain in the container.

Step-by-step explanation:

Given:

Amount of cream in the container = \frac{3}{4}\ pound

Amount of cream used to make crème brûlée = \frac{3}{8}\ pound

We need to find the amount of cream remain in the container.

Solution:

Now we can say that;

the amount of cream remain in the container is equal to Amount of cream in the container minus Amount of cream used to make crème brûlée.

framing in equation form we get;

amount of cream remain in the container = \frac{3}{4}-\frac{3}{8}

Now we will make the denominator common using LCM we get;

amount of cream remain in the container = \frac{3\times2}{4\times2}-\frac{3\times1}{8\times1}= \frac{6}{8}-\frac{3}{8}

Now denominators are common so we will solve the numerators.

amount of cream remain in the container = \frac{6-3}{8}=\frac{3}{8}\ pound

Hence \frac{3}{8}\ pound of cream will remain in the container.
