identify whether each if the following represents a quadratic function or not put yes or no
1. y = x² + 2
2. y = 2x - 10
3. y= 9 - 2x²
4. y = 2x + 2
5. y = 3x² + x² + 2
9514 1404 393
Answer:
yesnoyesnoyesStep-by-step explanation:
The function is quadratic if the highest degree of any term is 2. Equations 2 and 4 have degree 1, so are linear (not quadratic) functions. Equations 1, 3, and 5 have terms of degree 2 (at most), so are quadratic functions.
_____
We assume that two terms of degree 2 in equation 5 is intentional. If one of those is supposed to be of degree 3 (or more), then that function is not quadratic.

He is making $2.50x (x = amount of drinks sold)
Than we subtract the amount of money he lost - $15
$2.50x - $15

Find the mean rounded to the nearest tenth median mode and range 59,50,54,50,50
Answer:
Mean = 52.6
Median = 50
Mode = 50
Range = 9
Step-by-step explanation:
How to find the mean
The mean of a set of numbers is the sum divided by the number of terms.You add 59,50,54,50,50 then divide it by 5 because there are 5 numbersHow to find the median
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.How to find the mode
The mode is the element that occurs most in the data set. In this case, 50 occurs 3 times.How to find the range
Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 59 − 50 = 9Hope this helps
how to solve 1.2x+1.4y=2.7 and 0.4x-0.3y=0.9 in substitution
Answer:
x=0.8712, y=1.1818
Step-by-step explanation:
1.2x+1.4y=2.7 --(1)
0.4x-0.3y=0.9--(2)
1.2x=2.7-1.4y
x=(2.7-1.4y) / 1.2 --(3)
substitute (3) in (2)
[tex]0.4(2.7-1.4y) / 1.2 -0.3y=0.9[/tex]
[tex](1.8 - 0.56y) \frac{1}{3} - 0.3y = 0.9[/tex]
times both sides with 1/3
[tex] \frac{1}{3} (1.08 - 0.56y( \frac{1}{3} ) - 0.3y = 0.9)[/tex]
1.08-0.3=0.56y+0.1y
0.78=0.66y
y=1.1818
substitute y in (3)
x=2.7-1.4(1.1818) /1.2
x=0.8712

what is the slope intercept form of (4,-3) and (2,1)
Step 1: Find the Slope
Slope Formula: (y2 - y1) / (x2 - x1)
Point 1 = (4, -3)
Point 2 = (2, 1)
Slope = (1 - - 3) / (2 - 4) = (4) / (-2) = -2
Step 2: Find the Y-Intercept
Plug in the slope and one of the points into slope-intercept form and solve for b.
Slope-Intercept Form: y = mx + b
1 = -2(2) + b
1 = -4 + b
b = 5
Step 3: Put it all together
Plug in the slope and y-intercept into slope-intercept form.
Slope-Intercept Form: y = mx + b
y = -2x + 5
