1. Y = 10x
2. Y = 100 + 30x
3. Y = 50 + 1x
5. Y = 15 + .12x
Okay so in order to find your slope you're going to need to label your first set of coordinates! Since you know that -6 is X, you're going to label it X(subscript 1) and since you know that 7 is Y, you're going to label it Y(subscript 1).
You're going to want to do the same thing with the other set of coordinates as well. -6 will be X(subscript 2) and -2 will be Y(subscript 2).
Then you need to set the labeled coordinates up in the following formula:
m=y(subscript 2) - y(subscript 1) / x(subscript 2) - x(subscript 1)
and then solve for your slope!
Answer:
y= 5x
Step-by-step explanation:
since each x number is 1/5 of the y, it's 5 times x = y
Answer:
1/5
Step-by-step explanation:
Equation:
Points: (-3, -9) and (22, -4)
is the second y point that shows up on the question, basically go by order. So it's -4
is -9, because again, in order of which coordinates pop-up first in the question
is 22, is -3
Now input into the equation, to make it easier we'll split the fraction into 2 equations:
= and , we'll put them back in a fraction later
= -4 - (-9) = -4 + 9 = 5
= 22 - (-3) = 22 + 3 = 25
now put it in the fraction, remember y on top x on the bottom:
5/25, simplify, 1/5
To solve this we are going to use the formula for the lateral surface area of a regular pyramid:
where
is the lateral surface area.
is the perimeter of the base.
is the slant height.
We know for our problem that
and
, so lets replace those values in our formula and solve for
:
Now we know that the perimeter of the base of our regular triangular pyramid is 33 cm. Remember that the perimeter of a triangle is the sum of its 3 sides. Since our pyramid is regular, its base will be an equilateral triangle, so to f<span>ind the length of the base edge, we just need to divide the perimeter by 3:
</span>
<span>
We can conclude that the length of the base edge of our regular triangular pyramid is
11 cm.</span>
