Answer:
Step-by-step explanation:
y=x^2+x-30
y=x^2-(6-5)x-30
y=x^2-6x+5x-30
y=x(x-6)-5(x-6)
y=(x-5)(x-6)
Answer:
(x+6)(x-5)
Step-by-step explanation:
The product is -30 and the sum is 1.
Factors of -30 are
-1 and 30
-2 and 15
-3 and 10
-5 and 6
-5 + 6 = 1

Give the vertex for the quadratic function: f (x) = (x – 3) (x + 7)
Answers
Answer:
[tex]Vertex = (-2,-25)[/tex]
Step-by-step explanation:
Given
[tex]f(x) = (x - 3)(x + 7)[/tex]
Required
The vertex
[tex]f(x) = (x - 3)(x + 7)[/tex]
Open bracket
[tex]f(x) = x^2 -3x+7x-21[/tex]
[tex]f(x) = x^2 +4x-21[/tex]
Express -21 as 4 - 25
[tex]f(x) = x^2 +4x+4-25[/tex]
Group as:
[tex]f(x) = (x^2 +4x+4)-25[/tex]
Factorize the expression in bracket
[tex]f(x) = (x+2)^2-25[/tex]
The vertex form is:
[tex]f(x) = a(x - h)^2 + k[/tex]
Where the vertex is:
[tex]Vertex = (h,k)[/tex]
[tex]Vertex = (-2,-25)[/tex]

Given vector u = (3, 1) and v = (2,-4), determine the value of v – 4u in
component form.
Answers
Answer:
(-10, -8)
Step-by-step explanation:
4u
Each component of vector u is multiplied by 4. So
u = (3, 1)
4u = (4*3, 4*1) = (12,4).
v – 4u
Subtraction of the components of vector v by the components of the vector 4u. So
v - 4u = (2, -4) - (12, 4) = (2-12, -4 - 4) = (-10, -8)
The value is (-10, -8)

Answer:
Graph a line segment with endpoints (1,-8) and (-4,3).
Step-by-step explanation:
Just identity the endpoints of the line segment given, then swap the coordinates for each pair to graph it's inverse.
Original point -> Corresponding inverse point
(a,b) ->(b,a)
(-8,1) ->(1,-8)
(3,-4) ->(-4,3)
So graph the other inverse which is also a line segment using endpoints (1,-8) and (-4,3).
(The inverse graph is just a reflection of the original relation over y=x.)

Step-by-step explanation:
In the sinusoidal function [tex]y=a\sin(b(x-c))+d[/tex], [tex]|a|[/tex] represents the amplitude and [tex]y=d[/tex] represents the equation of the midline.
By definition sinusoidal functions ebb and flow with respect to this midline. Therefore, the minimums must occur at [tex]y=d-|a|[/tex] and the maximums must occur at [tex]y=d+|a|[/tex].
Thus, the minimum, or low, occurs at [tex]y=-3-|-19|=-3-19=\boxed{-22}[/tex] and the maximum, or high, occurs at [tex]y=-3+|-19|=-3+19=\boxed{16}[/tex].

Juan plans to use strategies to find 12x380 shows a strategy he could use
Answers
Answer:
3 x 4 x 380
Step-by-step explanation:
The correct strategy that he could use would be
3 x 4 x 380
This is basically splitting up the 12 into two numbers whose product equals 12. This shrinks the numbers and makes it easier to multiply the 380. Since it is easier to multiply 380 by 4 as opposed to 12. This strategy will still give you the same result as 12x380 and both will give you a product of 4,560

The radius is 7, but in the standard form for a circle, the radius is squared which means that the answer is NOT A and B.
So now you have only two choices, C and D both of which have the radius shown as 49 which is 7 squared.
The center is at (5,-1)
that means that x will be written as (x - 5)
And y will be written as (y + 1)
Note: the signs of the center always change to the opposite of what they were.
The answer is (x - 5)^2 + (y + 1)^2 = 49

A chessboard is a square that has 8 rows and 8 columns of square spaces. If the side of a square space is 3.25 inches long, what is the area in square inches of the chessboard?
Answers
Answer:
676 square inches
a = L²
It has been established in the question that the length and the width of the chessboard has 8 rows an 8 columns respectively
length = with
rows = columns
8 × 3.25 = 26inches
AREA = L²
A = 26²
A = 676 square inches
The area in square inches of the chessboard given the side length of a square space is 676 inches².
What is the area of the chessboard?
A square is a quadrilateral with four equal sides.
The first step is to determine the area of a square space.
Area = length²
3.25² = 10.56 in²
The second step is to multiply the area of the square space by the number of squares.
8x 8 x 10.56 = 676 inches².
