Answer:
vertex and x= -b/2a = 0
second point, when x=1, y=3
third point the mirror of the second point over the vertex

Find the volume. I need answer answer ASAP
Answer:
[tex]A=448[/tex]
Step-by-step explanation:
To find the volume of the given figure, one must multiply the lengths of all sides together. Therefore, set up an equation and solve,
[tex]V = (l)(w)(h)[/tex]
(V) indicates volume, (l) indicates the length of the base, and (h) indicates the height of the figure.
Substitute,
[tex]V=(8)(14)(4)[/tex]
Solve,
[tex]A=448[/tex]
A line passes through the point (12,0) and is parallel to the line with the equation y = 1∕6x + 1. What's the equation of the line?
Answer:
y=1/6x-6
Step-by-step explanation:
The first step is to set up the equation. Since the lines are parallel the slopes will be the same.
Note: y=mx+b; m is the slope and b is the y-intercept
Since we know that the slopes are the same all we have to do is plug in (12,0) in the equation to find b (y-intercept),
0=1/6(12)+b
0=6+b
-6=b
Now that we know b all we have to do is put it in the formula y=mx+b
y=1/6x-6.
Answer:
y = (1/6)x - 2
Step-by-step explanation:
"Parallel" means "has the same slope as..." so the slope of the line you want is 1/6.
y = (1/6)x + b where b is the y-intercept (now, find it using the point (12, 0) ).
0 = (1/6)(12) + b
0 = 2 + b
b = -2
The equation is y = (1/6)x - 2
Barbara says that the expression
6 - 3y + 4 + 2y is equivalent to the expression
5y + 10. Is Barbara correct?
Answer:
No she is wrong.
Step-by-step explanation:
Let's simplify step-by-step.
6−3y+4+2y
=6+−3y+4+2y
Combine Like Terms:
=6+−3y+4+2y
=(−3y+2y)+(6+4)
=−y+10
Answer:
=−y+10

Mrs. Ameldo's class has 5 students with blue eyes, 7 with brown eyes, 4 with hazel eyes, and 4 with green eyes.
Two students are selected at random. Find each probability.
HINT: These events are DEPENDENT
a) Probability of selecting a green-eyed student, and then a brown-eyed student = ___
1. 11/20
2. 7/100
3. 7/95
4. 7/10
b) P(two blue) = ___
1. 1/20
2. 5/20
3. 1/19
4. 2/5
Be sure to reduce your fractions!
(Remember, once a blue-eyed student is picked, there will be ONE LESS blue-eyed student and ONE LESS student in total.)
PART 2
a) P(hazel then blue) = ___
1. 1/19
2/ 7/380
3. 1/20
4. 1/2
b) P(brown then blue) = ___
1. 7/80
2. 7/76
3. 3/5
4. 1/4
Answer:
please mark my answer as brainliest:
7/100, 1/19
1/20, 7/80
Step-by-step explanation:
firstly, figure out the total amount of students:
5+7+4+4=20
remember that dependant variables means you have to multiply the values
a)
figure out probability of choosing a green eyed student:
4/20
figure out probability of choosing a brown eyed student:
7/20
multiply values:
4/20 x 7/20 = 7/100
b)
probability of choosing a blue eyed student:
5/20 = 1/4
probability of choosing another blue eyed student:
4/19 (bc theres 1 less)
multiply:
1/4 x 4/19= 1/19
PART 2
a)
probability of choosing a hazel eyed student:
4/20
probability of choosing a blue eyed student:
5/20 = 1/4
multiply:
4/20 x 1/4 = 4/80= 1/20
b)
probability of choosing a brown eyed student:
7/20
probability of choosing a blue eyed student:
5/20 = 1/4
multiply:
7/20 x 1/4 = 7/80

At the electronics emporium, 10 CDs are on sale. Marie can only afford to buy 3 CDs. How many combinations of CDs are possible?
Answer:
120 combinations of CDs are possible
Step-by-step explanation:
The total combinations could be
[tex]10C_3[/tex]
[tex]\frac{10*9*8*7!}{7!*3!}[/tex]
On further expanding, we get -
[tex]\frac{10*9*8}{3!} \\\frac{10*9*8}{3*2*1} \\= 10*3*4\\= 120[/tex]
Hence, 120 combinations of CDs are possible

Use the graph that shows the solution to f(x)=g(x). f(x)=1+2x/x g(x)=2+x What is the solution to f(x)=g(x)?
The solution if h(x) = g(x) is ±1
Solution to set of functionsGiven the following functions
h(x)=1+2x/x
g(x)=2+x
The solution of the function occur at h(x) = g(x)
If h(x) = g(x), then;
1+2x/x = 2 + x
Cross multiply
1+2x = x(2+x)
1 + 2x = 2x + x^2
Equate the resulting expression to zero to have;
x^2 = 1
x = ±1
Hence the solution if h(x) = g(x) is ±1

3. A class rolled number cubes. Their results are shown in the table. What is the experimental probability of rolling the number 1? Round your answer to the nearest tenth.
17.2%
16.4%
15.7%
17.5%
Answer:
15.7%
Step-by-step explanation:
Experimental probability is the probability of something that is determined by doing an experiment.
To find the probability, divide the number of rolling a one and add all the occurrences of every other result.
So,
42 / (42 + 44 + 45 + 44 + 47 + 46) =
42 / 268 =
0.156716 =
15.6716
Rounded to the nearest tenth, the probability of rolling a one would be 15.7%.
