Answer:
y = -x - 4
Step-by-step explanation:
the equation of a linear graph is y = mx + b
you know the m = -1
so now the equation is y = -x + b
from here, what you could do to find b is...
plug (-1, -3) into the equation
1) x = -1, y = -3
2) -3 = -(-1) + b
3) -3 = 1 + b
4) -4 = b
or you can look at the y-intercept which is where the line intersects with the y-axis
it seems to be (0, -4)
so "b" would be equal to -4
this makes the final equation y = -x + (-4) or y = -x - 4
Answer:
y = 9,25
Step-by-step explanation:
(5*0,3) + 2y = 20 (x=0,3)
1,5 + 2y = 20 . (-1,5)
2y = 18,5 ( /2)
y = 9,25
The answer should be the first one, 2. Do you need and explanation?
4x+y/2y-x
Start by replacing all of the variables.
4(2)+4/2(4)-2
Now work multiply.
8+4/8-2
Now add.
12/6
That is your fraction. But you must simplify it.
Its simplifies to 2.
The side lengths of the pool 10 ft and 45 ft.
<u>SOLUTION:
</u>
Given, a rectangle swimming pool is 8 feet deep.
One side of the pool is 4.5 times longer than the other.
Let the length of pool be n feet, the width will be 4.5n feet
The amount of water needed for the swimming pool is 3600 cubic ft
We have to find the dimensions of the pool. Now, we know that,
On taking square root on both sides we get,
So, the width will be 
Answer:
- x³+3x²-6
Step-by-step explanation:
a - b means
b-a
x²-6-( x³ - 2x²)
Distribute the minus sign
x²-6 - x³ + 2x²
Combine like terms
- x³+3x²-6
