O 16x^5 + 121
O 16x^10 + 121
O 16x^10 +88x^5 + 121
O 16x^25 +88x^5 + 121
Which expression is equivalent to (4x⁵ + 11)² ?
O 16x^5 + 121
O 16x^10 + 121
⊙ 16x^10 +88x^5 + 121
O 16x^25 +88x^5 + 121
Step-by-step explanation:
Using formula :
(a + b)² = a² + 2ab + b²
so that…
(4x⁵ + 11)²
= (4x⁵)² + 2(4x⁵)(11) + 11²
= 16x¹⁰ + 88x⁵ + 121
[tex]16x^{10} +88x^{5} +121[/tex] expression is equivalent to [tex](4x^{5} +11)^{2}[/tex].

49. The line containing (1, -3) and (3, y) is parallel to the line containing (5, -6) and (9, y).
How do I find y?
Answer:
y = 0
Step-by-step explanation:
Parallel lines have equal slopes
Calculate the slopes of both lines and equate them
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 3 ) and (x₂, y₂ ) = (3, y )
m = [tex]\frac{y-(-3)}{3-1}[/tex] = [tex]\frac{y+3}{2}[/tex]
Repeat with (x₁, y₁ ) = (5, - 6 ) and (x₂, y₂ ) = (9, y )
m = [tex]\frac{y-(-6)}{9-5}[/tex] = [tex]\frac{y+6}{4}[/tex]
Equating the 2 expressions
[tex]\frac{y+3}{2}[/tex] = [tex]\frac{y+6}{4}[/tex] ( cross- multiply )
4(y + 3) = 2(y + 6) ← distribute parenthesis on both sides
4y + 12 = 2y + 12 ( subtract 2y from both sides )
2y + 12 = 12 ( subtract 12 from both sides )
2y = 0 , then
y = 0

Answer:
y = 8x - 3
Step-by-step explanation:
1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.
2. Since we're already given the slope, 8, our equation looks like this so far: y = 8x + b.
3. We can use the formula [tex]b = y_1 - m * x_1[/tex] to find the y-intercept.
[tex]b = (5) - (8) * (1)[/tex] [tex]b = 5 - 8[/tex] [tex]b = -3[/tex]4. Since b = -3, our equation now looks like this: y = 8x - 3.
Therefore, the correct answer is y = 8x - 3.

determine whether each equation defines y as a function of x.
2x + y2 = 6
Answer:
NOT a function
Step-by-step explanation:
y^2 (not y2) is "the square of y"
The given 2x + y^2 = 6 can be solved for y as follows:
Subtracting 2x from both sides, we get y^2 = 6 - 2x, whose y-values are y = ±√(6 - 2x). Because there are two y-values associated with each x value, this is NOT a function. In a function there is only one y value for each x value.

Step-by-step explanation:
After divide, the solution of the expression is,
⇒ 54 ÷ 9 = 6
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The expression is,
⇒ 54 ÷ 9
Now, We can divide as;
⇒ 54 ÷ 9

the area of a parallelogram is 12x² + 38x + 20 square inches. it's base is 3x + 2 inches. find its height.
Answer:
4x+10
Step-by-step explanation:
3x *4x=12x²,so you can know the next
Answer:
h = 4x+10
Step-by-step explanation:
a = b(h)
h = a/b
Sub:
a = 12x^2 + 38x + 20
b = 3x + 2
12x^2 + 38x + 20 = 3x + 2 * h
Rewrite:
h = 12x^2 + 38x + 20 / 3x + 2
