You need to categorize the similar terms with the same exponential.
Here, 3 terms can be categorized: x^3, x^2 and constant
Then you simply manipulate the coefficient:
(5-9)x^3 + (-7+4)x^2 + (6+1) = -4x^3 - 3x^2 + 7
P of a rectangle= 2l + 2w
P = 2(48) + 2(20)
P= 96 + 40
P= 136m
The length of the rectangle is 136 meters.
I hope that helped.
The x-intercept is (11.43,0) I don’t know how to explain it to you
Answer:
y = 2*x + 4
Step-by-step explanation:
We know that a linear function can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
We know that if this line passes through the points (x₁, y₁) and (x₂, y₂) the slope can be written as:
a = (y₂ - y₁)/(x₂ - x₁)
So, here we know that our line must pass through the points (-2,0) and (0, 4)
Then the slope of this line is:
a = (4 - 0)/(0 - (-2))
a = 4/2 = 2
Then our line is something like:
y = 2*x + b
Now, to find the value of b we can use one of these two points, for example if we use the point (-2, 0), we know that, when x = -2, we must have y = 0.
0 = 2*(-2) + b
0 = -4 + b
4 = b
Then the equation for our line is:
y = 2*x + 4
