Take the y and x and 4 as a common factor and you will get 4xy(2yz+3x) the second one is the answer
Answer:
y= 2x+4
Step-by-step explanation:
To find slope its y2-y1/x2-x1
Plug it into any coordinate to get 2x
To find b in y=mx+b, you look at the y at the 0, in this case, "(0,4) Thefore the b is 5
Hello!
We use different formulas to calculate the areas of different shape.
RECTANGLE:
To find the area of a rectangle, we must simply multiply its length by its width. The formula for its area is:
A = l × w
SEMICIRCLE:
Since the formula for a circle is pi × r × r, we must use the same formula but divide it in half, because a semicircle is a half circle, which is why its area would also be half of a circle's. The formula for a semicircle's area is:
A = 1/2 pi × r × r
Tip:
Write these formulas down and memorize them so that you don't forget them. You'll have to use these formulas quite often when finding the area of these shapes.
Hmm, y=1 is directix
means it opens up or down
we will be using
(x-h)²=4p(y-k) where (h,k) is vertex and p is the distnace from focus to vertex and from vertex to direcitx
focus is (-1,-3)
find distance between y values because directix is a y value
midpoint is the vertex
from -3 to 1 is 2 units
since focus is below directix, it opens down, and p is negative
it is 2 units above focus
so at (-1,-1)
and p=-2
(x-(-1))²=4(-2)(y-(-1))
(x+1)²=-8(y+1) is da equation
Hello!
Let's change it to an equation.
Switch the equation around
First add 10 from 900
Divide both sides by 5
