The equation would be y = -5x - 7
Step-by-step explanation:
Shes wrong because she did it in 3 hours which means she would have made 3 cards and not 9.
19 if u add all separately but it is 89 it u don't
Step1: Find the area of the triangular lawn
Given, base of the triangle is y metres and the height is z metres
Area of the triangle =
2
1
× base × height
Therefore, area of the triangular lawn =
2

yz metre
2
.
Step 2:Find the cost of planting the grass
Rate of planting the grass is Rs. x per square metre.
Therefore, the cost of planting the grass on a triangular lawn =cost per square meter × area of the triangular lawn
=x×

Hence, the cost of planting the grass on a triangular lawn whose base is y metres and height is z metres is Rs.

Step-by-step explanation:
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
