If (8,0) is on y=bx+x^2, what is the least value of the function?
Answers
Greetings from Brasil...
(8; 0) ⇔ (X; Y) ⇒ so, according to the statement of the question, when X = 8 we have a Y = 0.
Y = bX + X²(8; 0) ⇒ X = 8 and Y = 0
0 = b · 8 + 8²
0 = 8b + 64
8b = - 64
b = - 64/8
b = - 8Then
Y = X² - 8XThe minimum value or least value of the function is -16 at x = 4 after plotting the graph.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
We have:
(8,0) is on y=bx+x²
Plug x = 8 and y = 0
0 = 8b + 64
b = -8
y = -8x + x²
Thus, the minimum value or least value of the function is -16 at x = 4 after plotting the graph.

do you compare a negative decimal to a positive decimal?
Answers
Answer:
Positive: Decimals are a part of a whole just like fractions are a part of a whole. Therefore, a positive decimal is always greater than a negative decimal.
Negative: When you have two negative decimals, the one closer to zero is always greater. The farther a negative decimal is from zero, the smaller its value.
All of it put together (same text as above):
Decimals are a part of a whole just like fractions are a part of a whole. Therefore, a positive decimal is ALWAYS greater than a negative decimal. When you have two negative decimals, the one closer to zero is always greater. The farther a negative decimal is from zero, the smaller its value.

A student wants to buy 4 bottles of lemonade that cost $1.65 each . if they pay with a bill how much will they get back?
Answers
Answer:
$3.40
Step-by-step explanation:
"A bill" = "1 bill"
Possibile bills = $1, $5, $10, $20, $50, $100
4 × 1.65 = 6.6
$6.60 is more than $5, but less than $10
Since the student is only using a single bill, it must be the $10 bill
10 - 6.6 = 3.4
$3.40

the difference between two number is 66 the ratio of number is 2 ratio 5 what are the two number
Answers
Step-by-step explanation:
Difference of some numbers is 66,
Let the number be x,
So, 5x - 2x = 66
=> 3x = 66
=> x = 66/3
=> x = 22
So, for finding the numbers 2x and 5x,
=> 2 * 22 , 5 * 22
=> 44 , 110
So the two numbers are 44 , 110 respectively,

Below you will find the question is broken down into two parts. The first is asking you to solve equations and show your work. The second is asking you to check someone else’s work. Please read instructions and make sure to complete all components. Solve the following equations, show your work for each equation in the three empty boxes below x+2=5 2n+5=n c.5(x+2)-7=3x+5 a) b) c)
Answers
Step-by-step explanation:
Equation (1) is :
x+2=5
Subtract 2 from both sides,
x+2-2=5-2
x=3
Equation (2) is :
2n+5=n
Taking like terms together,
2n-n=-5
n=-5
Equation (3) is :
5(x+2)-7=3x+5
⇒5x+10-7=3x+5
taking like terms together,
5x-3x=5-10+7
⇒2x=2
x=1
Hence, x =3, n = -5 and x = 1 is the required answer.

Given h(x) = -x2+3x, find h(5).
Answers
Answer:
-10, 40, or 5
Step-by-step explanation:
There are three ways of looking at this problem.
1.
h(x) = -x^(2) + 3x
When finding h(5), that is like saying that in the case that x = 5, find the value of the given expression,
using that knowledge, we can say
h(5) = -(5)^(2) + 3(5)
simplify
= - (25) + (15)
= -10
2.
h(x) = (-x)^(2) + 3x
Again,
When finding h(5), that is like saying that in the case that x = 5, find the value of the given expression,
using that knowledge, we can say
h(5) = (-5)^(2) + 3(5)
simplify
=25 + 15
= 40
3.
h(x) = -2x + 3x
Again,
When finding h(5), that is like saying that in the case that x = 5, find the value of the given expression,
using that knowledge, we can say
h(5) = -2(5) + 3(5)
simplify
= -10 + 15
= 5

Laraine worked 40 regular hours last week, plus 3 overtime hours at the 1.5 rate. Her pay was $476.15. What was her hourly rate?
Answers
Answer:
Her hourly rate is $10.7
Step-by-step explanation:
Here, we are interested in calculating Laraine hourly rate.
In the question, we are told that the overtime rate is 1.5 times the regular hours rate.
Now, let the regular hours rate be $x / hour
For a total of 40 hours, the total money made will be 40 * x = $40x
Now let’s look at the overtime;
Since the overtime is 1.5 times the regular and she had 3 overtime hours;
Money obtained from overtime will be 1.5 * x * 3 = $4.5x
Let’s add this to the regular and equate to the total money made;
4.5x + 40x = 476.15
44.5x = 476.15
x = 476.15/44.5
x = 10.7
Two town on a map are 2 1/4 inches apart.the actual distance between the towns is 45 miles. Which of the following could be the scale on the map?
Answers
Answer:
20 miles per inch
Step-by-step explanation:
Divide the miles by inches
45/ 2.25 = 20
20 miles for every inch
1/4 of an inch is equal to 5 miles
so 2 inches = 40 miles
0.25 inches = 5 miles
2.25 inches = 45 miles
