Kathy Is 12 years old and Ben is 16 years old. How many years ago was Ben three times Older than Kathy?
Setting up an equation to represent the scenario, we can conclude that Ben was 3 times older than Kathy 10 years ago.
Present age :
Kathy, k = 12 Ben, b = 16Serting up the equation thus :
Let the number of years = x
16 - x = 3(12 - x)
16 - x = 36 - 3x
Collect like terms
-x + 3x = 36 - 16
2x = 20
x = 10
Hence, Ben was 3 tines older than Kathy 10 years ago.

e^iπ = -1
2^57,885,161 - 1 is the largest known Mersenne prime number
2^43,112,609 - 1 is the second largest known Mersenne prime number
the greatest common divisor of any two integers which are coprime is 1 so
gcd(2^57,885,161 - 1, 2^43,112,609 - 1) =1
tan(π/4) = 1

Need help with lcm (Least common multiple)
Answer:
sure can help you shoot the question
Step-by-step explanation:
You can find the least common multiple of 2 numbers by using prime factorisation to find its index notation.
Example:
6=2×3
9=3^2
So to find the LCM of these to find the LCM of these numbers, you need to take the number with the higher index notation and the remaing factor and multiply them.

PLEASE HELP 15 POINTS 1. An architect is drawing a sketch for a new building. He uses graphs of lines on a coordinate plane to sketch out
his ideas. The architect has plotted the graph of the line 4x + 16y = 8.
What is the equation of the line he has graphed in slope-intercept form? (Reduce all fractions)
2
Write the equation in slope-intercept form perpendicular to the original line that goes through the point
(-6, -19)
3
Write the equation in slope-intercept form parallel to the original line that goes through the point (-8,6).
Answer:
1) [tex]y=-\frac{1}{4}x+\frac{1}{2}[/tex]
2) [tex]y=4x+5[/tex]
3) [tex]y=-\frac{1}{4}x+4[/tex]
Step-by-step explanation:
Question 1:
All you have to do is solve for y to get the slope intercept form.
[tex]4x+16y=8\\16y=-4x+8\\y=-\frac{1}{4}x+\frac{1}{2}[/tex]
So the equation is [tex]y=-\frac{1}{4}x+\frac{1}{2}[/tex]
Question 2:
Now for this one you have to find the line perpendicular to the previous equation.
Finding the slope:
So first we need to find the slope and usually the slope of a perpendicular line is the opposite and the reciprocal to the original equation. So instead of [tex]-\frac{1}{4}[/tex] it will be [tex]\frac{4}{1}[/tex] or even easier to manage [tex]4[/tex].
Finding the y-intercept:
For the y-intercept we need to plug in what we know into this formula....[tex]y=mx+b[/tex]
We know the slope is [tex]4[/tex] and we could use the ordered pair that they provided us with [tex](-6,-19)[/tex]. The -6 is the x and the -19 will be the y. Now let's plug in and solve.
[tex]y=mx+b\\-19=4(-6)+b\\-19=-24+b\\b=5[/tex]
Writing the equation:
Now we know all the information needed to write the equation.
[tex]y=mx+b\\m=4\\b=5[/tex]
Now we just fill it in the formula...
[tex]y=4x+5[/tex]
Question 3:
For a parallel equation the slope will be the same in order for them to be parallel to each other.
Finding the y-intercept:
For the y-intercept we need to plug in what we know into this formula....[tex]y=mx+b[/tex]
We know the slope is [tex]-\frac{1}{4}[/tex] and we could use the ordered pair that they provided us with [tex](-8,6)[/tex]. The -8 is the x and the 6 will be the y. Now let's plug in and solve.
[tex]y=mx+b\\6=-\frac{1}{4}(-8)+b\\6=2+b\\b=4[/tex]
Writing the equation:
Now we know all the information needed to write the equation.
[tex]m=-\frac{1}{4}\\b=4[/tex]
Now we just fill it in the formula...
[tex]y=-\frac{1}{4}x+4[/tex]

Hint: | Starting with zero, raise 7 to increasingly larger integer powers until the result exceeds 206.
Determine the powers of 7 that will be used as the places of the digits in the base-7 representation of 206:
Power | \!\(\*SuperscriptBox[\(Base\), \(Power\)]\) | Place value
3 | 7^3 | 343
2 | 7^2 | 49
1 | 7^1 | 7
0 | 7^0 | 1
Hint: | The powers of 7 (in ascending order) are associated with the places from right to left.
Label each place of the base-7 representation of 206 with the appropriate power of 7:
Place | | | 7^2 | 7^1 | 7^0 |
| | | ↓ | ↓ | ↓ |
206_10 | = | ( | __ | __ | __ | )_(_7)
Hint: | Divide 206 by 7 and find the remainder. The remainder is the first digit from the right.
Determine the value of the first digit from the right of 206 in base 7:
206/7=29 with remainder 3
Place | | | 7^2 | 7^1 | 7^0 |
| | | ↓ | ↓ | ↓ |
206_10 | = | ( | __ | __ | 3 | )_(_7)
Hint: | Divide the whole number part of the previous quotient, 29, by 7 and find the remainder. The remainder is the next digit.
Determine the value of the next digit from the right of 206 in base 7:
29/7=4 with remainder 1
Place | | | 7^2 | 7^1 | 7^0 |
| | | ↓ | ↓ | ↓ |
206_10 | = | ( | __ | 1 | 3 | )_(_7)
Hint: | Divide the whole number part of the previous quotient, 4, by 7 and find the remainder. The remainder is the last digit.
Determine the value of the last remaining digit of 206 in base 7:
4/7=0 with remainder 4
Place | | | 7^2 | 7^1 | 7^0 |
| | | ↓ | ↓ | ↓ |
206_10 | = | ( | 4 | 1 | 3 | )_(_7)
Hint: | Express 206_10 in base 7.
The number 206_10 is equivalent to 413_7 in base 7.
Answer: 206_10 =413_7

She did not make any errors.
Step 1: She wrote −3.4 incorrectly as + (−3.4).
Step 2: She identified changing the order of the numbers as the commutative property, which is incorrect.
Step 3: She identified changing the grouping of the numbers as the associative property, which is incorrect.

Step-by-step explanation:
bc it is
let the function be f defined by f (x) = 12 - 5x
(a) is it true that f (0) = 0 ? explain why or why not.
(b) evaluate f (-1)
(c) what value of a will make the equation f (a) = 6 true?
Answer
a)no
Step-by-step explanation:
a)12-5(0)
=12 not 0
b)12-5(-1)
=17
c)12-5x=6
-5x=6-12
x=1.2
hope it helps:)
Evaluating the function, it is found that:
a) No, since [tex]f(0) = 12[/tex], as when we replace x by 0, the value of y is 12.
b) [tex]f(-1) = 17[/tex]
c) [tex]a = \frac{6}{5}[/tex]
The function given is:
[tex]f(x) = 12 - 5x[/tex]
Item a:
f(0) is given by:
[tex]f(0) = 12 - 5(0) = 12[/tex]
So it is not true, since [tex]f(0) = 12[/tex].
Item b:
[tex]f(-1) = 12 - 5(-1) = 12 + 5 = 17[/tex]
Item c:
This is the value of x when f(x) = 6, thus:
[tex]12 - 5x = 6[/tex]
[tex]5x = 6[/tex]
[tex]x = \frac{6}{5}[/tex]
Thus:
[tex]a = \frac{6}{5}[/tex]

Mrs. Williamson had 18 students in her homeroom at the beginning of the school year and 24 students at the end of the year. What was the approximate percent increase in the number of students in Mrs. Williamson’s homeroom?
Answer:
The approximate % increase was around 33%
Step-by-step explanation:
Divide 24 by 18 and you convert the decimal into a percent which is just multiplying it by 100
There was an increase of 33.33 percent in Miss Williamson‘s homeroom
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then multiply it with b so that we collect b items per 100 items.
Since Percentage increase in the number of students can be calculated as;
=((Final number-Initial number)/Initial Number)×100
where the Initial number of students=18 students
Final number of students=24 students
Now substituting;
((24-18)/18)×100
=(6/18)×100
=33.33% increase
Hence, there was an increase of 33.33%.
