What is the equation of the line, in slope-intercept form, that passes through the point (0,7) and is perpendicular to the line
Alex Ar [27]
A line perpendicular to another occurs at the negative reciprocal of the slope of the original line. Why this is, I can further explain in the comments if you're interested. What is a reciprocal though? a reciprocal, if you're unfamiliar, is just the flipped form of it.

As an example, the negative reciprocal of 1/4 is -4/1. I multiplied 1/4 by a negative, and flipped the fraction.

So, what would the negative reciprocal of 3 be? well, you can imagine 3 to be 3/1 to help. so we multiply it by a negative, which gives us -3/1, and then we flip it, giving us -1/3. This is the slope of our unknown line. Because of this, we can mark out...well all of them haha. You need to double check your question and answers provided. With the info you've given me, none of your answers are correct. Let me know what happened if you can! if not, I would question your teacher, cause they messed up somewhere haha.

A serving of four home baked chocolate chip cookies weigh 50 grams and contains 12 grams of fat. What is the ratio in lowest ter
Vesna [10]

Answer:

Good luck

Step-by-step explanation:

<u>(50)</u>    half it

(<u>25</u>)  (<u>25</u>)    

(12)   (12)

(12.5) (12.5) (12.5) (12.5)

 (12)    (12)     (12)    (12)

0.5 + 0.5 + 0.5 + 0.5 = 2     (0.5= 1/2 or 0.5 or 0.50)

more examples: (2/4) (3/6) (4/8) (5/10)

So you are gonna have four holes and two twelves  

(12/12) (12/12) (12/12) (12/12)  (2/12)

I have no clue how to do this!!!
lara31 [8.8K]
Step One
Find z
All triangles have 180 degrees. No exceptions.
z + 47 + 90 = 180      combine like terms on the left.
z + 137 = 180            subtract 137 from both sides
z =  180 - 137        
z = 43 degrees.

Step Two
Use the sine function to find y
Sin(43) = opposite side / hypotenuse
opposite side = 35 

sin(43) = 35 / hypotenuse
hypotenuse = 35 / sin(43)
y = 35/0.6820
y = 51.32 

Solve using cos(x)
Note this problem could have been done in a shorter way.
Cos(47) = adjacent / hypotenuse.
hypotenuse = adjacent / cos(47)
y = 35 / cos(47)
y = 35 / 0.6820
y = 51.32 Both answers agree. It is a good thing to know how to do this question both ways.
