9(42) - 9(4) = 9(30) - 9(___)
Answer: 8 (I might have gotten it wrong tho) could be -8 too btw.
Step-by-step explanation:
42x9=378 and 9x4=36. 9x30=270 so that would make the equation 378-36=270-9(_). Simplified a bit more would be 342=270-9(_). Now subtract 270 from both sides you get 72=9(_) so it would be 8. Sorry if I’m wrong tho.
Answer:
9(42) - 9(4) = 9(30) - 9(-8)
Step-by-step explanation:
9(42 - 4) = 9(38)
9[30 - (-8)] = 9(38) because of rules of subtracting integers is:
Two like signs become a positive sign
Example:
3+(+2) = 3 + 2 = 5
6−(−3) = 6 + 3 = 9
Two unlike signs become a negative sign
Example:
7+(−2) = 7 − 2 = 5
8−(+2) = 8 − 2 = 6

The total fare (F) for x kilometers given that Php 50.00 is paid for the first 10 kilometers and the addition of Php 5.00 for every succeeding kilometer.
Given:
Php 50.00 is paid for the first 10 kilometers and the addition of Php 5.00 for every succeeding kilometer.
To find:
The total fare (F) for x kilometers.
Solution:
Let x be the number of kilometers and F(x) is total fare.
Number of kilometers cannot be negative. So, x is always greater than 0.
Php 50.00 is paid for the first 10 kilometers.
[tex]f(x)=50.00[/tex] for [tex]0\leq x\leq 10[/tex]
The addition of Php 5.00 for every succeeding kilometer.
[tex]f(x)=50.00+5.00(x-10)[/tex] for [tex]x\geq 10[/tex]
Therefore, the required function is
[tex]\begin{cases}50.00, & \text{ if } 0\leq x\leq 10\\ 50.00+5.00(x-10), & \text{ if } x\geq 10 \end{cases}[/tex].

What’s the distance of the points (2,-9) and (-1,4)
Answer:
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
Distance = √ ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2
Substitute the actual values of the points into the distance formula.
√ ( ( − 1 ) − 2 ) 2 + ( 4 − ( − 9 ) ) 2
Simplify.

3.) $400 at 3% for 1 year
4.) $100 at 1% for 8 years
5.) $50 at 48% for 6 months
9514 1404 393
Answer:
1, 3, 5
Step-by-step explanation:
The interest earned is given by the formula ...
I = Prt
For the reference amount, that is ...
I = ($150)(0.04)(2) = $12
For the choices, the earned interest amounts are ...
1) ($300)(.02)(2) = $12
2) ($150)(.06)(1.5) = $13.50
3) ($400)(.03)(1) = $12
4) ($100)(.01)(8) = $8
5) ($50)(0.48)(0.5) = $12
Accounts 1, 3, 5 would earn the same interest.

10. 28.17
Step-by-step explanation:
The square root of the numbers to the nearest hundredth is:
√138= 11.75
2. √405=20.12
3. √800= 28.28
4. √1150= 33.91
5. √6500= 80.62
6. √580= 24.08
7. √300= 17.32
8. √250= 15.81
9. √284= 16.85
10. √794= 28.18
The square root of a number is a value that when multiplied by itself it gives the number, For example, the square root of 16 is 4. This is because 4 x 4 = 16
Square root is denoted with this symbol √
In order to round off to the nearest hundredth, look at the number in the thousandth place, if the number is equal or greater than 5, add 1 to the hundredth value. If this is not the case, add zero to the hundredth value.
√138= 11.75
2. √405=20.12
3. √800= 28.28
4. √1150= 33.91
5. √6500= 80.62
6. √580= 24.08
7. √300= 17.32
8. √250= 15.81

the square root of 66 is between 8.12 and _,and it is closer to_
Answers:
Square root of 66 is between 8 and 9
It is closer to 8
===================================================
Explanation:
Note that 66 is between the perfect squares 64 and 81
So we can say the following:
[tex]64 < 66 < 81\\\\\sqrt{64} < \sqrt{66} < \sqrt{81}\\\\8 < \sqrt{66} < 9[/tex]
Meaning the square root of 66 is between the integers 8 and 9.
The decimal approximation of 8.12 helps confirm this (because 8.12 is between 8 and 9).
------------------
[tex]\sqrt{66}[/tex] is closer to 8 than it is to 9 since 66 is closer to 64, than 66 is to 81.
Also, we're told that [tex]\sqrt{66} \approx 8.12[/tex] giving us more proof that [tex]\sqrt{66}[/tex] is closer to 8.

Three times the square of a number is greater than a second number. The square of the second number increased by 6 is greater than the first number. Which system of inequalities represents these criteria?
Given:
Three times the square of a number is greater than a second number.
The square of the second number increased by 6 is greater than the first number.
To find:
The system of inequalities represents these criteria.
Solution:
Let the first number be x and the second number be y.
Three times the square of a number is greater than a second number.
[tex]3\times x^2>y[/tex]
[tex]3x^2>y[/tex] ...(i)
The square of the second number increased by 6 is greater than the first number.
[tex]y^2+6>x[/tex] ...(ii)
Therefore, the system of inequalities represents these criteria has inequalities [tex]3x^2>y[/tex] and [tex]y^2+6>x[/tex], where x is first number and y is second number.
The system of inequalities represents given criteria are [tex]3x^{2} > y[/tex] and [tex]y^{2} +6 > x[/tex].
Let us take the numbers as x and y respectively.
First number = x
Second number = y
What is inequality?
Inequality is the relationship between two expressions that are not equal to one another.
Three times the square of the first number is greater than a second number:
This means, [tex]3x^{2} > y[/tex]
The square of the second number increased by 6 is greater than the first number:
This means, [tex]y^{2} +6 > x[/tex]
Therefore, the system of inequalities represents given criteria are [tex]3x^{2} > y[/tex] and [tex]y^{2} +6 > x[/tex].

A 1×6 square unit rectangular grid has to be covered with six 1×1 square unit tiles. Three of the tiles are yellow, two are white, and one is blue. In how many ways can this task be done if

no two neighboring tiles are the same color?
The number of ways the task of Rearranging the rectangular grid can be done if no two neighboring tiles are the same color is;
P(no two neighboring tiles are same) = 60 ways
We are given;
Number of yellow tiles; n_y = 3
Number of white tiles; n_w = 2
Number of blue tiles; n_b = 1
Now, if no two neighboring tiles can be the same tile Color, it means that;
P(no two neighboring tiles are same) = number of ways when no restriction/((n_y)! × (n_w)! × (n_b)!)
>> P(no two neighboring tiles are same) = 6!/(3! × 2! × 1!)
