Convert y = 5x2 + 20x + 11 to VERTEX form.
Answer:
y =5(x+2)2−6 is the correct ans
The vertex form of quadratic equation is expressed as:
y = a (x - h) + k
We manipulate the given equation to be the same as the vertex form. First we transpose the constants to the left-hand side.
y - 14 = 5x+ 20x
Then, we factor out in right hand side the coefficient of the x² term.
y- 14 = 5 (x + 4x)
We divide the coefficient of the x term with 2 and take its square. We add this value to both sides of the equation but we should remember that in the left-hand side we should multiply this value with five to keep it balanced.
y - 14 + 20 = 5 (x + 4x +4)
We simplify the right-hand side as:
y =5(x+2)2−6

Step-by-step explanation:
The vertex form is one of the most commonly used forms for quadratic functions, as it emphasizes the dimensions of the substring graph's vertex.
Vertex form:A vertex form of a solution is a unique way of spelling out such a parabola's equation. Usually, a quadratic equation is expressed as an x² + bx + c, which is a parabola if plotted on a graph.[tex]\to y= 5x^2+20x+11\\\\[/tex]
Solving the equation:
[tex]\to y= 5(x+2)^2-9\\\\\to y= 5 (x^2+2^2+ 2\times 2 x)-9\\\\\to y= 5 (x^2+4+ 4x)-9\\\\\to y= 5x^2+ 20+ 20x-9\\\\\to y= 5x^2+ 20x +11\\\\[/tex]
So, the value is "5(x+2)²-9".

Step-by-step explanation:

let x represent blueberry pie and y blackberry pie, then
x + 2y = 53 → (1)
10x + 3y = 224 → (2)
Multiplying (1) by - 10 and adding to (2) will eliminate x
- 10x - 20y = - 530 → (3)
Add (2) and (3) term by term to eliminate x
0 - 17y = - 306
- 17y = - 306 ( divide both sides by - 17 )
y = 18
Substitute y = 18 into either of the 2 equations and solve for x
Substituting into (1)
x + 2(18) = 53
x + 36 = 53 ( subtract 36 from both sides )
x = 17
Then
the cost of 1 blueberry pie is $17 and 1 blackberry pie is $18

The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
(11)
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 2) and (x₂, y₂ ) = (0, 3)
m = [tex]\frac{3-2}{0-4}[/tex] = - [tex]\frac{1}{4}[/tex]
The line crosses the y- axis at (0, 3 ) ⇒ b = 3
y = - [tex]\frac{1}{4}[/tex] x + 3 ← equation of line
(12)
(x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (4, 2)
m = [tex]\frac{2-1}{4+3}[/tex] = [tex]\frac{1}{7}[/tex] , then
y = [tex]\frac{1}{7}[/tex] x + b ← is the partial equation
To find b substitute either of the 2 points into the partial equation
Using (3, 1 ), then
1 = [tex]\frac{3}{7}[/tex] + b ⇒ b = 1 - [tex]\frac{3}{7}[/tex] = [tex]\frac{4}{7}[/tex]
y = [tex]\frac{1}{7}[/tex] x + [tex]\frac{4}{7}[/tex] ← equation of line
6/7 times 3/4 = x
IN SIMPLEST FORM
Answer:
I believe 6/7 times 3/4 in the simplest form is 9/14 because you aren't able to put anything in both of those numbers
Step-by-step explanation:
The value of x in the equation (6/7) × (3/4) = x is 9/14.
To find the value of x in the equation (6/7) × (3/4) = x.
We can simply multiply the two fractions together.
Multiplying the numerators and denominators gives us:
(6 × 3) / (7 × 4)
= 18/28
The fraction 18/28 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.
(18/2) / (28/2)
= 9/14

If a =
-5i and b = -4x, then find the value of a+b in fully simplified form.
If a =-5i and b = -4x the value of a+b in the fully simplified form will be 5i-4x.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
It is given that,a =-5i and b = -4x
We have to find the value of a+b in a fully simplified form.
We have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
=a+b
= -5i-4x
Thus, if a =-5i and b = -4x the value of a+b in the fully simplified form will be 5i-4x.

How will the solution of the system y>2x+2/3 and y<2x1/3 change if the inequality sign on both inequalities is reversed
Answer:
We have the inequalities:
y > 2*x + 2/3
y < 2*x + 1/3
First, we need to understand how to see the solutions of each one of these.
y > 2*x + 2/3
The solution set of this inequality will be ALL the points above the line:
y = 2*x + 2/3
And the solution of the inequality:
y < 2*x + 1/3
Will be the set of all the points below the line:
y = 2*x + 1/3
Notice that line "y = 2*x + 2/3" is above than the line "y = 2*x + 1/3"
Then the system:
y > 2*x + 2/3
y < 2*x + 1/3
Has no solutions.
If we reverse both inequalities, we will get:
y < 2*x + 2/3
y > 2*x + 1/3
Now the solution of the first inequality will be all of the region below the line, and the solution for the second will be all the region above the line.
In this case, the solution of the system will be all the region between both lines, as we can see on the graph below. Where the solution of the system is the doubled shaded area.
