HELP ME PLEASE The roots of a quadratic equation can be found using the graph what are the roots of these equations?
Answers
(-1,4)
Explanation:
On the left if you estimate it brings to a -1 and on the right if you count boxes bring to a 4
Hope its correct
Answer:
the roots of this quadratic expression are: x = -1 and x = 4
Step-by-step explanation:
You need to find at which x-values the graph crosses the x-axis (this is when y = 0, and therefore the roots of the quadratic equation represented via the graph).
In our case notice that the graph crosses the x-axis at the points:
x = -1 (on the left), and x = 4 (on the right)
Therefore the roots of this quadratic expression are: x = -1 and x = 4.

On Saturday, Mark sold 2 7/8 gallons of lemonade.
On the same day, Regan sold 2/3 as much lemonade as Mark.
How much lemonade, in gallons, did Regan sell?
Answers
Answer:
Regan sold [tex]\mathbf{\frac{23}{12}}[/tex] gallons of lemonade
Step-by-step explanation:
Operations with Fractions
Mark sold [tex]2\frac{7}{8}[/tex] gallons of lemonade.
Regan sold [tex]\frac{2}{3}[/tex] as much lemonade as Mark
We can find the portion of lemonade Regan sold by multiplying both fractions. But first, we must convert to improper fraction:
[tex]2\frac{7}{8}=2+\frac{7}{8}=\frac{23}{8}[/tex]
Now we multiply:
[tex]\frac{23}{8}\cdot \frac{2}{3}=\frac{46}{24}=\frac{23}{12}[/tex]
Regan sold [tex]\mathbf{\frac{23}{12}}[/tex] gallons of lemonade

What is the area of the trapezoid?
Answers
Answer:
A=78ft
Step-by-step explanation:
The area of a trapezoid is A=(a+b)/2 *h
a=long base
b=short base
h=height
For your trapezoid, it will look like this:
a=15ft
b=11ft
h=6ft
Let's add those into the equation:
A=(15+11)/2 *6
Okay, let's solve it! Using PEMDAS, we know parenthesis are first.
A=26/2 *6
Now we divide!
A=13*6
Multiply! And don't forget to add your unit.
A=78ft

What are the coordinates of the image of
A after the given composition of tranformations?
Dilation: center (0, 0); scale factor 5,
Translation: (x, y) (x-9,y +11).
Answers
Answer:
[tex]A'' = (6, -34)[/tex]
Step-by-step explanation:
Given (Points)
[tex]C = (-3,8)[/tex]
[tex]A = (3,-9)[/tex]
[tex]P = (-1,-10)[/tex]
Transformations:
Dilation: Center (0,0); Scale factor = 5
Translation: (x, y) --> (x-9,y +11).
Required
Determine the image of A
[tex]A = (3,-9)[/tex]
Apply the first transformation:
i.e. dilation by a scale factor of 5
[tex]A'=A * 5[/tex]
[tex]A'=(3,-9) * 5[/tex]
[tex]A'=(3* 5,-9* 5)[/tex]
[tex]A'=(15,-45)[/tex]
Apply the second transformation:
i.e. translation: (x, y) --> (x-9,y +11).
[tex]A'=(15,-45)[/tex]
[tex]A'' = (15 - 9, -45 + 11)[/tex]
[tex]A'' = (6, -34)[/tex]
Hence, the image of A is (6,-34)

For each graph below, state whether it represents a function.
Answers
Step-by-step explanation:
1. Not a function There is no correlation plus there is two y values for the same x.
2.Not a function, There is two y values for the same x
3.Yes, you can draw a linear line through the points to represent the equation, also there is one x for one y.
4.Yes, this is a step function. It seems there are two y values for same x. but the shaded circle means to include it and the open circle means dont include it so it is a function.
5.No, this is a parabola but this function has two y values for the same x
6. Yes, this is a absolute value function and there is multiple x values for the same y so it IS a function
Graph 3,6,4 represents a function because the x’s do not repeat and it passes the vertical line test. Which means 1,2,5 is not a function because the x's do repeat and it does not pass the vertical line test

change 4 and 4 on 9 to an improper fraction
Answers
Answer: 40/9
Step-by-step explanation:
First multiply the number 4 and the denominator 9 together which is 36 in this case. Then add the remaining 4 which takes you to 40 then the denominator will stay the same so the answer will be 40/9
Because each one of the whole number = 9/9ths
So when we multiply as above, you are adding 9/9 + 9/9 + 9/9 + 9/9 + 4/9. Add the numerators, but the denominator stays the same.

Substitute x in the right column with the values in the left column to find d, e, and f.
Answer:
d = 1
e = 4/9
f = 16/81
Step-by-step explanation:
d is 1 because any term raised to the power of zero equals one
e: (2/3)² = 2²/3² = 4/9
f: (2/3)^4 = 2^4/3^4 = 16/81

50/10 = 5 and 60/10 = 6, which is why E) is the third answer
Answer:
B D and E
Step-by-step explanation:
Remark
It's hard to know how to tackle this. I suppose the easiest way is to divide the numerator and denominator by a common factor.
2/4
The common factor is 2
Divide the 2 by 2 and the 4 by 2
2/2 = 1
4/2 = 2
The fraction reduces down the 1/2 which is not 5/6
10 / 12
The common factor is 2.
10/2 = 5
12/2 = 6
Looks like this is your answer. But is it the only one.
11/6
These two have no common factor. The answer is 11/6 which is not 5/6
20 / 24
The common factor of these two is 4
20/4 = 5
24/ 4 = 6
This is also = to 5/6
50 / 60
The common factor is 10
50/10 = 5
60/10 = 6
That's equal to 5/6 as well.
