(x+4)²= (x+4)×(x+4)

Use the FOIL method to simplify

F=First (multiply the first number of each expression)
O=Outside (multiply the outside edges of each expression)
I= Inside (multiply the inside edges of each expression)
L= Last (multiply the last number of each expression)

x times x= x²
x times 4= 4x
4 times x= 4x
4 times 4= 16

Add them together, we have: x²+4x+4x+16
We can simplify this by adding like terms
4x+4x=8x

Final expression= x² + 8x + 16

C. Find a parametrization for the line segment with endpoints (-1, 3) and (3, -2).
wel

Answer:

x(t) = -1 + 4t

y (t) = 3 - 5t

Step-by-step explanation:

The end points of the line segment are (-1, 3) and (3, -2).

Let a = (-1,3) and b = (3,-2)

Now, find the value of (b-a)

(b-a) = ((3+1), (-2-3))

b-a = (4, -5)

Therefore, the parametrization of the given line segment is

r(t) = a + (b-a)t

r(t) = (-1,3) +(4,-5)t

r(t) = (-1+4t, 3-5t)

We can rewrite this as

x(t) = -1 + 4t

y (t) = 3 - 5t

Write a linear function f with the values f (0) =-1 and f (3)= -10
dmitriy555 [2]

Answer:

The linear function is y = -3x -1.

Step-by-step explanation:

A linear function is given by the formula,

y = (m)x + c, where m is the slope and c is the y intercept of function.

The following two points lie on the graph; (0,-1) and (3,-10)

Inserting this two points we get,

-1 = c

-10 = (m)(3) + c,

solving this two equations we get,

m = -3 and c= -1

Thus, the linear function is given by,

y = -3x -1
