Answer:
Hello. It does have a maximum and minimum. You would have to use the formula x=-b/2a to find both of them. So first you have the equation which is x=2(x-2)^2+3, which you would have to make it an equation which is equals to F(x)=2x^2-8x+11. So b would be 8 and a would be 2. Enter them into the formula. So the answers would be (2,3)

what is 31=xy+15? for segment addition
Answer:
x = 16/y
or
y =16/x
Step-by-step explanation:
31=xy+15
subtract 15 from both sides of the equation:
xy = 16
x = 16/y
or
y =16/x
André e Bruno foram a uma lanchonete e compraram lanches e sorvetes iguais. Bruno comprou 2 lanches e 1 sorvete e pagou R$21,00. Já André comprou 3 lanches e 2 sorvetes, pagando R$33,00. Qual era o preço, em reais, de cada lanche que André e Bruno compraram nessa lanchonete? R$5,00. R$9,00. R$10,50. R$10,70.
Answer:
the price of each snack be R $9.00
Step-by-step explanation:
Let us assume the snack be x
And, the ice cream be y
Now according to the question
2x + y = $21
And,
3x + 2y = $33
Now multiply by 2 in equation 1
So,
4x + 2y = $42
3x + 2y = $33
x = 9
Hence, the price of each snack be R $9.00

Answer:
72 meters
Step-by-step explanation:
12 times 9 is 72
Answer:
243 m²
Step-by-step explanation:
Given the scale is 4 : 6 = 2 : 3 , then
scale of areas = 2² : 3² = 4 : 9
area of scale drawing = 12 × 9 = 108 cm²
let x be the actual area then using proportion
[tex]\frac{4}{108}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )
4x = 972 ( divide both sides by 4 )
x = 243
Actual area = 243 m²

Josie wants to build a slide that is 15 feet long. If the angle of elevation for the side will be 30 degree, how high in feet will the top of the slide be ?
Answer: 7.5
Step-by-step explanation: draw a right triangle to represent the slide. the slide is 15 feet long, so the hypotenuse of the right triangle would be 15 feet. The angle from the bottom is 30 degrees according to the question. You want to find the angle opposite from the 30 degree angle so use sin(30). Sin=opposite/hypotenuse so sin(30)=x/15 sin(30) is 1/2 so 1/2=x/15. You multiply by 15 on both sides to get x by itself. 1/2*15=7.5

The scatter plot shows the amount of sleep Aria got the night before a test and her test scores. Use the y-intercept, (0, 62), and the point (6, 80) from the line on the scatter plot. What is the equation of the trend line? (*Note: Enter your response as an equation in y=mx+b form. Enter no spaces & use only lower-case letters. Ex: y=10x+5 ) *
Answer:
y = 3x + 62
Step-by-step explanation:
Trend line equation in the form :
y = mx + b
m = slope
b = intercept
Using the points :
(0, 62) ; (6, 80)
Slope, m = Rise / Run = (y2-y1) / (x2 - x1)
y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0
m = (80 - 62) / (6 - 0)
m = 18 / 6
m = 3
Intercept, b = value of y when x = 0
(0, 62) ; hence, b = 62
y = 3x + b
y = 3x + 62
Find the area for this problem
Answer:
494 cm^2
Step-by-step explanation:
Find area od the rectangle:
14 x 26 = 364
Find area of the triangle:
10 x 26 = 260
260/2 = 130
Add the areas together:
364 + 130 = 494

Solve the equation. x6−9=7 x = ___ (type only an integer - no words, variables, or equal signs)
Answer:
We want to solve the equation:
x*6 - 9 = 7
To solve this we need to isolate x in one side of the equation.
First, we need to add 9 in both sides of the equation to get:
(x*6 - 9) + 9 = 7 + 9
x*6 - 9 + 9 = 16
x*6 = 16
Now we can divide both sides by 6, to get:
x*6/6 = 16/6
x = 16/6 = 2.66
This is not an integer as the question wants, so i only can suppose that the question is incorrectly written.
If the equation was something like:
x/6 - 9 = 7
Using the same approach than before (the only difference is that we multiply both sides by 6 in the second step), we would get:
x/6 = 7 + 9 = 16
x/6 = 16
x = 16*6 = 96
x = 96
Which is an integer, so i suppose that the actual equation is "x/6 - 9 = 7" instead of "x*6 - 9 = 7"

The box and whisker plots represent the number of minutes spent by users on two different social media groups. Which THREE statements are correct when comparing the plots?
A) The median time for users of Group B is 40 minutes.
B) Group B has greater median value than Group A.
C) The data for Group B varies slightly more than Group A.
D) The spread of the data for Group A is 25 minutes.
E) The spread of the data for Group A is 40 minutes.
Answer: I feel the answer is C
Step-by-step explanation:
The three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.
What is a box and Whisker plot?A box and whisker plot displays the minimum value, lower quartile (Q1), median, upper quartile (Q3), and maximum values of a data set.
Let's analyze each of the given statements given the box and whisker plots for both groups:
Statement A is TRUE:
Median time for Group B = 40.
Statement B is FALSE:
Median value for Group A is between 45 and 50
Median value for Group A is 40.
Therefore, Group B does NOT have median value greater than Group A.
Statement C is TRUE:
The interquartile range (IQR) for Group A and Group are similar, therefore, data for Group B varies slightly more than Group A.
Statement D is TRUE while E is FALSE:
Spread for Group A (IQR) = 55 - 30 = 25 minutes
Therefore, the three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.

Jillian and Josie are trying to find the value of the function, 8x^4-12x^3+3x^2-7x+4 at x=-1. Jillian says the only way to find the answer is to plug in -1. Josie says, no, there is another way. Who is right? Justify your answer.
Answer:
Josie is correct.
Step-by-step explanation:
There are other ways of finding the value of the function at x = 1.
For example, one way would be graphing or using a graphing device to graph the function. Once graphed, looking for the y-value where x = 1 would also provide the answer.
