Answer:
(10,0)(-1,0)
Step-by-step explanation:
x^2 - 9x - 10 = 0
(x - 10)(x + 1) = 0
The two solutions are
x - 10 = 0
x = 10
or
x+1 = 0
x = - 1
Answer:
x=10, x=-1
Step-by-step explanation:
Hi there!
We are given this equation:
x²-10=9x
And we want to solve it by factoring
Factoring is easier to do when all of the terms are on the same side, so let's subtract 9x from both sides
x²-9x-10=0
Now we must think of two numbers that add up to -9, but multiply to get -10
Those numbers are -10 and 1
So factor the polynomial using FOIL:
(x-10)(x+1)=0
Now split and solve via the zero product property:
x-10=0
Add 10 to both sides
x=10
x+1=0
Subtract 1 from both sides
x=-1
Hope this helps!

Answer: just read
Step-by-step explanation:
So first you plot the points, then calculate how many units it takes from the point that is Sean’s house to his School. Show your work on that by drawing out your skip counting. Then you plot the rest of the points and fpro this calculation: the distance from Sean’s house to his school+ from his school to the grocery store. Then you calculate the distance (in units! ! ! Which means one box is one unit) : distance from Sean’s house to the school+ from school to the commmunity center. Then two calculations you made above you compare. So whichever one is greater is your answer for part b.

Answer:
x=5/3, and x=-1
Step-by-step explanation:
The absolute value sign makes anything inside of it positive. So there are two possible x values for this problem. When we open the absolute value brackets we need to create two different equations. 3x-1=4, and 3x-1= -4. Solving these two equations we can find two possible values of x. x equals 5/3, and -1.

solve for W
14/W=26/39
Answer:
I think the answer is 21
Step-by-step explanation:
The answer is 21 because we can simple reduce 26/39 = 2/3. And now that you have done that all we need to do is find what 14/w = 2/3 this is quite simple as we just have to mutiply the 3*7 to get 21 as your answer. I don't know if this is correct or not but this is my best answer.
Answer:
21
Step-by-step explanation:
14 : w = 26 : 39
w = 14 * 39 : 26
w = 21

Determine whether each sequence is an arithmetic sequence. If yes, then state the common difference.
4, 7, 9, 11, 12,...
Answer:
Not arithmetic
Step-by-step explanation:
Arithmetic sequences go up by the same number or down by the same number.
From 4 to 7 thats up by 3
From 7 to 9 that's up by 2
Conclusion: not arithmetic
Answer:
The sequence is not an arithmetic sequence.
Step-by-step explanation:
4 is getting added by 3 to get 7
7 is getting added by 2 to get 9
9 is getting added by 2 to get 11
11 is getting added by 1 to get 12
As you can see, the sequence is not consistent. Therefore, it is not an arithmetic sequence.

Answer:
k > 24
Step-by-step explanation:
To solve an inequality you must isolate the variable. Do this by using the properties of equality, specifically the property of multiplication. To get k by itself multiply both sides by 4. This way k > 24. Then, you can check your answer by plugging in any number less than or equal to 24 and solving to see if it's true.
Answer:
k = 24
Step-by-step explanation:
k is greater than or equal to 24 and 4/4 = 1 so if k is greater than or equal to 24 than that could be 24/4 and that would equal 6. that is the answer to your question.
