Hey there! I'm happy to help!
The slope of a perpendicular line is always the negative reciprocal of the original.
QUESTION 1
For the first one, we have a slope of -2/7. To find the reciprocal you flip the numerator and denominator, giving us -7/2. Then, we want the negative reciprocal, so since two negatives make a positive our perpendicular slope is 7/2.
QUESTION 2
Let's first rearrange our equation to be in slope intercept form.
3x+5y=-15
Subtract 3x from both sides.
5y=-3x-15
Divide both sides by 5.
y=-3/5x-3
First we find the reciprocal of -3/5, which is -5/3. This is the normal reciprocal, but we want the negative one, and since two negatives makes a positive, our slope is 5/3.
Have a wonderful day! :D
Answer:
(x + c) (x - c)
Step-by-step explanation:
For any number the polynomial can be factored as (x + c) (x - c)
Answer:
in
Step-by-step explanation:
I don't know if you got this pic but this is the answer for this pic
To get the answer, first, you need to turn them into decimals
16 1/5 =16.2 and 5 2/5 =5.4
then all you need to do is to divide the numbers
16.2 divided by 5.4 equals to 3
so the answer is 3
