Answer:
4y^4 + 6y = 256y + 6 = 262y
Step-by-step explanation:
Remove the variables for a second and think of the problem as a normal expression; 4^4 + 6
Simplify the first term; 4^4 = 256
Now, add 6; 256 + 6 = 262
Add back in the variable; 262y
Answer:
2y(2y+3)
Step-by-step explanation:
2y(2y) +6y factor 2y out of 4y^2
2y(2y)+2y(3) factor 2y out of 6y
2y(2y + 3) factor 2y out of 2y(2y)+2y(3)
two cubes each measure 7 units on each side. write and espression using exponents to represent the total volume of the cubes.
Answer:
7*6=42 then 42*2=84 hope that helps.
Answer:
7^3 + 7^3 units^3
OR
(7^3)2 units^3
Step-by-step explanation:
Volume = length x width x height
In cubes, length = width = height
So, volume = 7 x 7 x 7 = 7^3
2 cubes:
7^3 + 7^3 units^3
OR
(7^3)2 units^3

There is a bag filled with 5 blue and 6 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting at least 1 red?
Answer:
There are 6+5 marbles.
Of those, 5 are red.
The chances of drawing a red marble are 5/11
Since you replace the marble you drew, the chances each draw remain 5/11
You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11. The odds of that also being red are 5/11… but we only care about that 5/11ths the time
5/11*5/11=25/121
5t + 15 ≥ 50
What's the answer?
Answer:
Subtract 15 from both sides.
5t > 35
Divide both sides by 5.
t > 7

Find the measures of the sides of triangle DEF, then classify it by its sides. YOU MUST SHOW WORK TO GET CREDIT!
D(-2, 3), E(5, 5), F(-4, 10)
Answer:
FE = 10.30
ED = 7.62
FD = 7.28
Step-by-step explanation:
First, use coordinate system to draw a square that each angle of triangle reach the sides of the square, then use Pythagoras theory to find the length of the sides(c^2=a^2+b^2)
FE = root(9^2+5^2) = root(106) = 10.30
ED = root(3^2+7^2) = root(58) = 7.62
FD = root(2^2+7^2) = root(53) = 7.28
The temperature was 8℉. It dropped so that the temperature was 0℉. What integer represents the change in temperature?
Answer:

Step-by-step explanation:
The temperature dropped 8 degree, resulting in a negative change. So the integer to represent it would be negative 8 degrees.
A bag had 7 orange rocks , 6 green rock , 1 white rock ,7 black rocks , and 2 yellow you randomly pull a rock from the bag ,keep it out , and then pull out another one .
What is the probability of getting a yellow rock and then a n orange rock ?
Answer:
[tex]Probability = \frac{7}{253}[/tex]
Step-by-step explanation:
Given
[tex]Orange = 7[/tex]
[tex]Green = 6[/tex]
[tex]White = 1[/tex]
[tex]Black = 7[/tex]
[tex]Yellow = 2[/tex]
Required
Probability of selecting a yellow then orange rock
From the question, we understand that the probability is that of without replacement.
Since the yellow, is first picked.
We need to determine the probability of picking a yellow rock, first.
[tex]P(Yellow) = \frac{n(Yellow)}{Total}[/tex]
[tex]P(Yellow) = \frac{2}{7 + 6 + 1 + 7 + 2}[/tex]
[tex]P(Yellow) = \frac{2}{23}[/tex]
The rock has reduced by 1;
Next is to determine the probability of picking an orange rock
[tex]P(Orange) = \frac{n(Orange)}{Total - 1}[/tex]
[tex]P(Orange) = \frac{7}{7 + 6 + 1 + 7 + 2- 1}[/tex]
[tex]P(Orange) = \frac{7}{22}[/tex]
The required probability is calculated as thus:
[tex]Probability = P(Yellow) * P(Orange)[/tex]
[tex]Probability = \frac{2}{23} * \frac{7}{22}[/tex]
[tex]Probability = \frac{14}{506}[/tex]
[tex]Probability = \frac{7}{253}[/tex]

What is the slope of the two points (-2,7) and (4,-8)
Answer:
-15/6
Step-by-step explanation:
If you look at the first number in each point, the x coordinate, you see the 2nd point is 6 forward from the 1st point. Now the 2nd number is the y coordinate, and you can see it goes down 15 from the 1st coordinate. So y/x is the slope.
Answer: -2 1/2
Step-by-step explanation:
Slope= Yb-Ya/Xb-Xa
In this case= (-8-7)/(4- -2)
This equals -15/6
Simply to -2 1/2
order them from least to the greatest value.

State the domain of f•g. Then find f•g, including any additional restrictions necessary on the domain of the composition
Answer:
Answer is option A
Step-by-step explanation:
The required function [f o g(x)] is -7/√(x + 3).
The domain of the function [f o g(x)] > - 3.
What is a function?A function is the relation between two sets. The first one is called domain and the second one is called range.
Given, f(x) = - 7/x
g(x) = √(x + 3)
Therefore, f o g(x)
= f[g(x)]
= f[√(x + 3)]
= -7/√(x + 3)
Now, the domain of f o g(x) > - 3.

Answer:

Step-by-step explanation:
What value of x makes this equation true? 2(4x-3) - 8= 4+2x
Answer:
What value of x makes this equation true? 2(4x-3) - 8= 4+2x HERE YOU GO!!
Step-by-step explanation:
We need to eliminate one of the variables to solve the other.
4x+5y = 8
2x-3y = 18
I will multiply the second equation by -2.
-2*(2x-3y = 18)
-4x + 6y = -36 and then add the two equations
4x + 5y = 8
-4x + 6y = -36
+ adding here
11y = -24
y = -24/11
substitute x in one of the equations to find y.
2x-3y=18
2x - (3*-24/11) = 18
2x = 126/11
x = 126/22
