What is the maximum value of 5 - 4x - x2 and the value of x for which the maximum occurs? Explain your answer.
Answer:
Max value: 9
Max x value: -2
Step-by-step explanation:
We're trying to find the vertex of y = 5 - 4x - x²
We can try to convert this equation to vertex form
First, subtract 5 from both sides
y = 5 - 4x - x²
- 5 -5
y - 5 = -4x - x²
Then add -4 to both sides (this is because this the sqaure of half b -4)
y - 5 - 4 = -4x - x²+ 4
y - 9 = -4 - 4x - x²
Factor the right side of the equation
y - 9 = -(x + 2)(x + 2)
y - 9 = -(x + 2)²
Add 9 to both sides
y - 9 = -(x + 2)²
+ 9 + 9
y = -(x + 2)² + 9
To find the max values we have to make it to where x + 2 = 0
x + 2 = 0
- 2 - 2
x = - 2
When we make equation inside the parenthesis 0, we get y = 9
y = -(-2 + 2)² + 9
y = -(0)2 + 9
y = 9

Select each equation which is equivalent to 60% of 25.
0.6 • 25 = x
x • 1.6 = 25
610=x25
60100=25x
x25=60100
6.0 • 25 = x
Answer:
answer is 0.6 x 25 = x
Step-by-step explanation:
to find % of number, you simply just need to convert the percent to a decimal, which is done by division of 100.
60 / 100 = 0.6
Midpoints
H is the midpoint of iJ, and IH, = 0.75. What is the value of HJ?
IH + HJ = 2 (IH)
0.75 + HJ = 2(0.75)
0.75 + HJ = 1.5
HJ = 1.5 - 0.75
HJ = 0.75
What is the numerical coefficient in the polynomial 4y+ 6?
Answer:
4y
Step-by-step explanation:
A coefficient is a number with a variable and no sign in between them.
The numerical coefficient in the polynomial 4y+ 6 is 4.
What is expression?A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of phrases. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the equation x/2 + 6.
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.Given expression:
4y + 6
As, A coefficient is a number that is multiplied by a variable in an expression.
here the term that contain variable is 4y.
So, the coefficient is 4.
Hence, the numerical coefficient in the polynomial 4y+ 6 is 4.

-2x+7=3-(-2x)
Answer:
X = 1
Step-by-step explanation:
-2x + 7 = 3 - ( -2x)
-2x + 7 = 3 +2x (- - = +) (+ + = +) and (different signs always negative: - + = -)
(any term or numbers moved from one side of the = sign goes from negative to positive or from positive to negative, from multiplying to dividing and from dividing to multiplying. First isolate the additions or subtractions.)
-2x + 7 = 3 + 2x
-2x + 7 - 3 = 2x
-2x + 4 = 2x
4 = 2x + 2x
4 = 4x (a number next to a letter is multiplying. It goes to the other side of the equation dividing)
4 /4 = x
X = 1
-2x + 7 = 3 - (-2x)
-2x + 7 = 3 + 2x
-2x - 2x = 3 - 7
-4x = -4
x = 1

In 2013 the population of Indonesia was 200 million. The population was increasing by 2.3% per year. What will the population of Indonesia be in 2022.
Answer:
241,400,000
Step-by-step explanation:
200,000,000×100÷2.3= 4,600,000
2022-2013= 9
4,600,000×9= 41,400,000
200,000,000 + 41,400,000 = 241,400,000
Answer:
241,400,000
Step-by-step explanation:
200,000,000×100÷2.3= 4,600,000
2022-2013= 9
4,600,000×9= 41,400,000
200,000,000 + 41,400,000 = 241,400,000
Seiji and Gavin both worked hard over the summer. Together they earned a total of $450. Gavin earned $50
more than Seiji.
(a) Write a system of equations for the situation. Use s for the amount Seiji earned and g for the amount
Gavin earned.
(b) Graph the equations in the system. Let the x-axis = Seiji and the y-axis = Gavin. (Complete the
numbering on the axis)
(c) Use your graph to estimate how much each person earned.
[a] If the total is 450 and Gavin (g or y) earned 50 more than Seiji (s or x) then we can create the following system:
{ s + 50 = g
{ g + s = 450
[b] See attached
[c] Gavin earned $250 and Seiji earned $200
Using the graph, we will look at where the points intercept. The x will be Seiji, and the y will be Gavin. Using this, we can see the answer is (200, 250) leaving Seiji with 200 dollars and Gavin with 250 dollars

Ellen makes and sells bookmarks. She graphs the number of bookmarks sold compared to the total money earned. What is the rate of change for the function graphed to the left?
Answer:
Given coordinates on the graph is (4,0), (8,10), (12,20).
We need to find the rate of change for the function graphed.
Actually rate of change is the second name of slope.
So, we need to find the slope between given coordinates.
We know slope formula
Let us choose first two coordinates (4,0), (8,10).
(x1,y1) = (4,0) and (x2,y2) = (8,10).
Plugging values of x1,x2,y1 and y2 in slope formula, we get
Slope=
Therefore, rate of change is 5/2 or $2.5 earned per bookmark sold.

Step-by-step solution :
STEP

Equation at the end of step 1
(23x2 - 6x) - 3
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 8x2-6x-3
The first term is, 8x2 its coefficient is 8 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 8 • -3 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -6 .
-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5
-6 + 4 = -2
-4 + 6 = 2
-3 + 8 = 5
-2 + 12 = 10
-1 + 24 = 23
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Find the value of X, show work
Answer: 0
Step-by-step explanation: you just have to divide a little bit then you just multiply.
Answer: x=7.2
Step-by-step explanation:
Use the Pythagorean theorem:a^2+b^2=c^2 c being the hypothenuse and b and a being the other 2 sides
so 7.8*7.8=60.84 3*3+9 60.84-9=51.84 then the square of that would be 7.2 so x=7.2
