Answer:

Step-by-step explanation:
So we have the expression:

Distribute. Multiply (4x+5) to each term:

Distribute:

Combine like terms:

Add and simplify:

And this is in descending order, so it's in standard form.
2(100)2
200x2
400
Is the answer
Answer:
3xyzsquare root of xy^2
the third option
Step-by-step explanation:
look for what you cn take from all of it equally
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange - 4x + 4y = 4 into this form by adding 4x to both sides
4y = 4x + 4 ( divide all terms by 4 )
y = x + 1 ← in slope- intercept form
with slope m = 1
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 1, thus
y = - x + c ← is the partial equation
To find c substitute (- 4, 5) into the partial equation
5 = 4 + c ⇒ c = 5 - 4 = 1
y = - x + 1 ← equation of perpendicular line
Answer:
(1,0)
Step-by-step explanation:
we can't factor this so we'll use the quadratic formula

(use both of them because usually there are two zeroes)
We have

Therefore the x intercept is just (1,0)
