Answer :
A) y = 7x + 4
Step-by-step explanation:
we need to see the equations 1 by 1
instead of y and x we need to put the value given
I am taking the last x and yes values as they are small numbers and will be easy to calculate
x = -1
y = -3
placing the values in equation :
A) y = 7x + 4
-3 = 7 × -1 + 4
-3 = -7 + 4
-3 = -3
So we got the answer same ! so the correct answer will be A) y = 7x + 4
let's check other one too to confirm overselves
b) y = 4x + 7
-3 = 4 × -1 + 7
-3 = -4 + 7
-3 = 3 NOT AN ANSWER
Answer:
Step-by-step explanation:
One pump will fill 200l in 20 minutes
So the rate of filling per pump will be 10l/minute (200/20)
Let the number of minutes it will take to fill the 600l be x minutes
Now, since the rate of filling per pump is 10 l/minute
Then in x minute, they would have filled 10l/minute * x = 10x liters
So it is now this 10x liters that will be equal to 600
To find x, we simply divide
10x = 600
x= 600/10
x = 6 minutes

The first thing we must do for this case is to calculate the area of both yards.
We have then:
front yard:
A1 = (50) * (80)
A1 = 4000 feet ^ 2
Back yard:
A2 = (10) * (30)
A2 = 300 feet ^ 2
"Jayden wants to lay sod on his front yard and on half of his back yard"
Then, the total amount will be:
A = A1 + (1/2) A2
Substituting:
A = 4000 + (1/2) (300)
A = 4000 + 150
A = 4150 feet ^ 2
Answer:
jayden needs to purchase 4150 square feet of sodd
