Answer:
Step-by-step explanation:
If the slopes are the same but the y-intercepts are different, the system has no solution.
If the slopes are different, the system has one solution.
If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
Answer:
Step-by-step explanation:
If you mean linear systems. If lines have a different slope there will be one solution. If they have the same slope (parallel) and a different y intercept there are zero solutions. If they have same slope and y intercept than they are the same line and have an infinite number of solutions.

What is the probability of getting 2 of the same colour?
PLZ answer fast urgant help needed!
Answer:
0.5041 = 50.41% probability of getting 2 of the same colour
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is the probability of getting 2 of the same colour?
Both blue or both red
Since they are replaced, we have, in each trial:
6 blue from a set of 6 + 5 = 11
5 red from a set of 6 + 5 = 11
Probability of both blue:
Each with 6/11 probability. So
[tex]P = (\frac{6}{11})^2 = \frac{36}{121}[/tex]
Probability of both red:
Each with 5/11 probability. So
[tex]P = (\frac{5}{11})^2 = \frac{25}{121}[/tex]
Total:
[tex]p = \frac{36}{121} + \frac{25}{121} = \frac{61}{121} = 0.5041[/tex]
0.5041 = 50.41% probability of getting 2 of the same colour
A student tries to solve the equation 2(x-7)=x-9. the student's work is shown to the right.
Describe any errors. Then solve the equation correctly
Answer:
I can't see what the student did to solve the equation so I'll just solve the equation step by step here.
Step-by-step explanation:
2(x-7)=x-9
2x-14=x-9 Use distributive property to solve the parenthesis
x-14=-9 Subtract the x on both sides
x=5
Answer:
See step by step
Step-by-step explanation:
He didnt use the distributive property.
How to solve it is
[tex]2(x - 7) = x - 9[/tex]
[tex]2x - 14 = x - 9[/tex]
[tex]x - 14 = - 9[/tex]
[tex]x = 5[/tex]

Compare the numbers using >,<, or =
874,023______874,233
5,493,820______5,492,483
Answer:
<
>
Step-by-step explanation:
We have two sets of numbers and are asked to compare using the <, >, = symbols.
Remember :
< means less than
> means greater than
= means equal to
One thing I was told in 2nd grade when this subject came over for the first time, was to think of the symbol as a crocodile and that it wants to eat the bigger number, with the opening of it being the mouth of the crocodile. Therefore, out of 874,023 and 874,233. Which is the bigger number?
874,223.

HELP! 50 POINTS! 75 if I chose your answer as the best! easy!
Step-by-step explanation:
Question 1:
In the expression 4y - 6x² + 5 + 9x, there are
4 terms. (4y/6x²/5/9x) A term consists of a coefficient and a variable, or otherwise a constant term like 5.
Question 2:
4(6x - 5) - 7x
= (24x - 20) - 7x
= 17x - 20.
Therefore the correct answers are
the 1st and 2nd options.
Question 3:
3x - 8y + 11x - 4 + 5y
= (3x + 11x) + (5y - 8y) - 4
= 14x - 3y - 4.
The 4th option is correct.
Question 1
There are 4 terms.
They are 4y, 6x^2, 5, and 9x.
Terms are separated by operation signs (+, -, ×, ÷).
Even if a constant is multiplied by a variable, if there isn't a multiplication sign, it's one single term.
Question 2
Use the distributive property. Multiply the term outside the variable by the terms inside.
4×6x = 24x
4×(-5)=-20 (there's a negative sign incase you don't see it)
24x-20-7x
Since 24x and 7x are like terms, you can subtract them.
24x-7x=17x
17x-20
You can see the first and second choices are correct.
Question 3
Combine the like terms.
The like terms are
3x and 11x
-8y and 5y
-4
Add them all.
3x+11x=14x
-8y+5y=-3y
-4
So the expression simplified is...
14x-3y-4
It's the third choice.

After spending many hours studying for your math class, you decide to reward yourself with a case of cream soda. Unfortunately, Corner Market only had a warm case left. You buy several bags of ice and decide to chill it at home. When you get home, the temperature of the soda is 76° F, and you proceed to pack it in ice. After 10 minutes, the temperature cooled to 70° F. If cream soda is best served at 60° F or cooler, how much longer must you wait to enjoy your chilled cream soda?
Answer:About sixteen minutes.
Step-by-step explanation: After you find out that Ten minutes is six degrees you divide ten by six and get 1.666. Then you multiply that by the time remaining and get 16 minutes rounded. or seventeen if you are specific.

Find the output, g, when the input, r, is 4.
g=25−3r
plzzzzzz help me i need to finish
Answer: g = 13 / Thats the output
Step-by-step explanation:
g = 25 - 3r
Its telling you the r is 4 since its the input.
g = 25 - 3 ( 4 ) see!! just plug in the number
Now Solve
g = 25 - 12
g = 13
Answer:
g = 13
Step-by-step explanation:
since r = 4, you make the equation :
g=25-3(4)
first you multiply 3 and 4 and you get 12
g=25-12
and 25 - 12 is 13 which equals :
g = 13
