c
Step-by-step explanation:
Answer:
In standard form it is x^4 - 12x^3y + 54x^2y^2 - 108x y^3 + 81y^4.
Step-by-step explanation:
(3y)^4 + 4C1(3y)^3(-x) + 4C2(3y)^2(-x)^2 + 4C3(3y)(-x)^3 + (-x)^4
= 81y^4 - 108y^3x + 54y^2x^2 - 12yx^3 + x^4
4 I THINK is the answer not 100% sure though
Answer:
y=-2x+5. (4,-3)
Step-by-step explanation:
1) What's being asked in other words is to write a function. So the initial point is (1,3). In x-axis, a translation movement can only be to the right or to the left. Similarly for y-axis the possible movements are shifting up or down. The question says, 3 units right for x-cordinate and 6 units down for y cordinate. So the final point of this translation would be (1+3,3-6) =(4,-3)
2) To write a linear function we need to find out the slope:


y=-2x+5
<u>Proof:</u>
x=1
y=-2(1)+5
y=3 Then (1,3)
x=4
y=-2(4)+5
y=-8+5
y=-3 Then (4,-3)
Answer:
Nico, Raj and Sandra are correct
Step-by-step explanation:
we have

<em>Method 1</em>
Solve for x
That means ----> isolate the variable x
we have

Multiply by 5/2 both sides


subtract 6 both sides


<em>Method 2</em>
Solve for x
That means ----> isolate the variable x
we have

Multiply by 1/2 both sides


Multiply by 5 both sides


subtract 6 both sides


<em>Method 3</em>
Solve for x
That means ----> isolate the variable x
we have

Apply distributive property left side


subtract 2 both sides


Multiply by 5/2 both sides


therefore
Nico, Raj and Sandra are correct
