Write an equation in slope-intercept form that is perpendicular to y = -7x + 3 and passing through (14.1).
igomit [66]

Answer:

y = 1/7x -1

Step-by-step explanation:

1) Find the slope.

- In this case, the equation given is in simplest form so you can easily come to the conclusion that '-7' is the slope. But, since the math question wants a slope-intercept form in perpendicular form, the slope would actually be 1/7.

2) Use the point-slope form and substitute the values available. Then solve.

m (slope) = 1/7

(a, b) = (14, 1)

y - b = m(x - a)

y - 1 = 1/7(x - 14)

y - 1 = 1/7x - 2

y = 1/7x - 1

The result is your answer.

Hope this helped (please tell me if I made a mistake or if you have any confusion and I will resolve it under the comments) ^^

Plot the following fractions and decimals on the number line.
OLga [1]

Answer:

hmmmmmmmm, cool

well, here ya go

Step-by-step explanation:

0.7 is AKA 7/10, which is a little less than 3/4, AKA 0.75, so in between 3/4 and 1

1/3 is larger than 1/4 but smaller than 1/2, so prob somewhere in the middle of those two.

8/7, since the numerator is larger than the denominator, is larger than 1 by 1/7, so goes right in front of 1.

0.4, AKA 4/10,  is a little less than 1/2, AKA 0.5, but larger than 1/3, AKA 0.333333333(goes on forever) so it goes in the middle of those

0.125, AKA 1/8, is the smallest of the bunch, and it's half of 1/4, AKA 0.25. That means its dead last, half between 1/4 and 0.

5/6 is the largest, around 8.333333(more foreverness)/10, which is larger than 3/4, AKA 0.75, so it goes between that and 1.

So, for your final answer:

0---0.125---1/4---1/3---0.4---1/2---0.7---3/4---5/6---1---8/7

I am not sure if thats what your structure for the question is, so I hope that that order helps. i could also put it in all decimals if it helps,  or all fractions, so let me know in the comments.

Which equation represents a line which is perpendicular to the line 5x + 2y = 12?
o-na [289]

Answer:

<h2>          y = ²/₅ x - 3</h2>

Step-by-step explanation:

Changing to slope-intercept form:

5x + 2y = 12         {subtract 5x from both sides}

2y = -5x + 12         {divide both sides by 2}

y = -⁵/₂ x + 6

y=m₁x+b₁   ⊥   y=m₂x+b₂   ⇔    m₁×m₂ = -1

{Two lines are perpendicular if the product of theirs slopes is equal -1}

y =-⁵/₂ x + 1    ⇒     m₁ =  -⁵/₂

-⁵/₂× m₂ = -1      ⇒   m₂ = ²/₅

So, any line perpendicular to 5x + 2y = 12 must have slope m =²/₅
