Whats the parallel equation of y=1/3x-2 goes through point (0,6)

loris [4]

You know that two lines are parallel if they have the same slope, so the new line will also have slope

$m=\frac{1}{3}$

Because the equation of the given line is written in the form

$\begin{gathered} y=mx+b \\ \text{Where} \\ m\colon\text{slope of the line} \\ b\colon\text{ y-intercept} \end{gathered}$

Then, you can use point slope equation, which is

$\begin{gathered} y-y_1=m(x_{}-x_1) \\ \text{Where} \\ (x_1,y_1)\colon\text{ point through which the line passes.} \\ m\colon\text{slope of the line} \end{gathered}$

So,

$\begin{gathered} (x_1,y_1)=(0,6) \\ \text{ And you have} \\ y-y_1=m(x_{}-x_1) \\ y-6=\frac{1}{3}(x-0) \\ y-6=\frac{1}{3}x-0 \\ y-6=\frac{1}{3}x \\ \text{ Add 6 to both sides of the equation} \\ y-6+6=\frac{1}{3}x+6 \\ y=\frac{1}{3}x+6 \end{gathered}$

Therefore, the equation of the line that is parallel to y=1/3x-2 and goes through point (0,6) is

$y=\frac{1}{3}x+6$

After a 30% price reduction you purchase a new computer for $840. What was the computers price before the reduction?

solong [7]

840 = 70% (100% - 30%)

840 : 70 * 100 =

1200$ is your answer

-----------------------------------

1200 - 30% = 840%

Mrs. B. invested ¢30,000; part at 5%, and part at 8%. The total interest on the

Sonbull [250]

Answer:

Let p be the amount invested at 8%. Then the amount invested at 5% would be 30,000-p. So:

.08p+.05(30,000-p)=2100

.03p+1500=2100

.03p=600

p=20,000

$20,000 was invested at 8%; $10,000 was invested at 5%

What’s is the answer

kvasek [131]

When you are multiplying an exponent directly into a number/variable with an exponent, you multiply the exponents together.

For example:

$(x^{2} )^{3} = x^6$

$(x^{3} )^5=x^{15}$

When you are multiplying a variable with an exponent by another variable with an exponent, you add the exponents together.

For example:

$(x^{2} )(x^{3})=x^{5}$

$(x^{1} )(x^{2})=x^{3}$

$(\frac{(x^{-3})(y^{2})}{(x^{4})(y^{6})} )^{3}=\frac{(x^{-9})(y^{6})}{(x^{12})(y^{18})}$

You multiply 3 into each exponent in the numerator and the denominator

$\frac{(x^{-9})(y^{6})}{(x^{12})(y^{18})}= \frac{y^{6}}{(x^{9})(x^{12})(y^{18})}$

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.

$\frac{y^{6}}{(x^{21})(y^{18})} = \frac{1}{(x^{21})(y^{12})}$

When you have something like this:

$\frac{x^{2}}{x^5}$

You subtract the exponents together, so:

$\frac{x^2}{x^5} = x^{2-5} = x^{-3} = \frac{1}{x^3}$

Your answer is the second option

I need help on my algebra 1 homework ! If anyone could help it would be greatly appreciated.

dmitriy555 [2]

For numbers 9 and 10, you just need to find the slope and y-intercept. To find the slope, do change in y over change in x which would be -5 minus -3 over -2 minus -1. and that would equal -2 over -1 which simplifies to 2. So 2 is the slope! and that's a little confusing so I'll attach a picture showing those steps.

to find the y-intercept, plug in an ordered pair in the slope-intercept equation: y=mx + b. Let's just use (-1, -3). So for y, you'd plug in y from the ordered pair, -3, and for the slope (m) you'd plug in 2, since you found that earlier. for x, use the ordered pair again, -1. And you're trying to find the y-intercept (b) so leave that blank to find. So plug all the numbers in and you get -3 = 2(-1) + b. Which you then solve as a one step equation. Again, I've attached a picture if the words are confusing.

for number 10, do the same thing to find the slope! And they've given you the y-intercept in the problem (0,-5). Now I feel like I've written too much so I'll cover the other problems in another answer lol.
