Answer:
4x² + 12xy + 9y²
Step-by-step explanation:
Assuming you require the expansion
(2x + 3y)²
= (2x + 3y)(2x + 3y)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x + 3y) + 3y(2x + 3y) ← distribute both parenthesis
= 4x² + 6xy + 6xy + 9y² ← collect like terms
= 4x² + 12xy + 9y²
Answer:
[tex] {4x}^{2} + 12y + {9y}^{2} [/tex]
Step-by-step explanation:
[tex](2x + 3y) {}^{2} \\ {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} \\ = {(2x)}^{2} + 2 \times 2x \times 3y + {(3y)}^{2} \\ = 4 {x}^{2} + 12y + 9 {y}^{2} \\ hope \: it \: helps[/tex]
Write the equation in standard form. Identify the vertex, axis of symmetry, and direction of opening of the parabola. show work
y = x ^ 2 + 2x + 2
what conclusions can you draw about the roots of the equation x^3+x^2-2x+12=0
Answer:
x=-3
Step-by-step explanation:
If x=-3, then
x³+x²-2x+12=-27+9+6+12=-27+27=0
If this is true, then x+3 is a factor. So:
x³+x²-2x+12/x+3=x²-2x+4
So the factors of x³+x²-2x+12 are:
(x+3)(x²-2x+4)
((x²-2x+4) has no real roots)........
The ratio of scrambled eggs to hard-boiled eggs served at a restaurant is 6: 2. Find the number of hard-boiled eggs when the restaurant serves 15 scrambled eggs.
Answer:
Its 15/2 but something is probably wrong with the question.
Step-by-step explanation:
h is hard boiled eggs. s is scrambled eggs. s/h=6
15/h=6
15=6h
h=15/6=5/2 Something is probably wrong with the question because who would serve 1/2 of a egg.
Find the mode for the scores 3,850 5,300 8,550, 4.300: 5,350
Answer:
No Mode
Step-by-step explanation:
The mode is the answer that occurs most in a set of numbers, but there are no repetitive numbers in your set, so the answer is no mode.
shift the graph of y=x down 2 units
Answer:
shown in drawing attached
y=x-2
Step-by-step explanation:
Shift each point down by two. First plot y=x, then shift down by 2 for each point.
please give thanks :)
You have to subtract 2 from the y-coordinate to shift the graph of y = x down to 2 units.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
To shift the graph of y = x down 2 units, you can subtract 2 from the y-coordinate of each point on the graph.
This will be done by replacing y with y-2 in the equation, so the new equation would be y = x + (-2) which is y = x - 2
So the new equation for the graph will be y = x - 2
This will cause the graph to move down 2 units along the y-axis.

What are the coordinates of the image of vertex G after a reflection across the line y = x?
Answer:
The coordinates of the image of vertex G are (-5, 4)
Step-by-step explanation:
Let us revise some cases of reflection
If the point (x, y) reflected across the x-axis , then its image is (x, -y) If the point (x, y) reflected across the y-axis , then its image is (-x, y) If the point (x, y) reflected across the line y = x , then its image is (y, x) If the point (x, y) reflected across the line y = -x , then its image is (-y, -x)From the given figure
∵ The line of the reflection is y = x
→ That means we will switch the coordinates of the point to find its image
∵ The coordinates of vertex G are (4, -5)
∴ The x-coordinate = 4 and the y-coordinate = -5
→ Switch the two coordinates
∴ The coordinates of its image G' are (-5, 4)
∴ The coordinates of the image of vertex G are (-5, 4)
The graph of y = f(x) is graphed below. What is the end behavior of f(x)?
9514 1404 393
Answer:
(b) signs of the infinities are opposite
Step-by-step explanation:
The graph shows a trend toward +∞ as x gets more negative, and toward -∞ as x gets more positive. That is, the sign of the end behavior of y is opposite that of x. This is expressed by the second choice.

D.251.5
here is a semicircle of radius x.
Answer:
a) C
b)
3.142x + 2x = 25.71
5.142x = 25.71
x = 5
Step-by-step explanation:
Expression for Semicircle perimeter: xπ + 2x. (C)
Therefore x(π + 2) = 25.71 and x = 25.71 / (π + 2) = 5.
y – 11 = 3(x – 2)
in standard form
Answer:
3x + y = -5
General Formulas and Concepts:
Pre-Algebra
Distributive PropertyEquality PropertiesAlgebra I
Standard Form: Ax + By = C
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate y₁ - y coordinate m - slopeStep-by-step explanation:
Step 1: Define
[PS] y - 11 = 3(x - 2)
Step 2: Rewrite
Find Standard Form
Distribute 3: y - 11 = 3x - 6Subtract 3x on both sides: -3x - y - 11 = -6Add 11 to both sides: -3x - y = 5Factor -1: -1(3x + y) = 5Divide -1 on both sides: 3x + y = -5The Ratio of the length of Sam's rope is to that of his friend Ryan's rope is 2 : 7.
