Find the least common multiple of 9w2 and 12w4 .

1 answer:

5 0

9w² and 12w⁴

9w² = 3*3w²
12w⁴ = 3*4*w⁴

To create Least common multiple we need
1) all numbers, and if they are repeating more than one time, we take largest number of repetitions (we have 2 repetitions of 3 in 9, so we will take 3*3)
So, for number part 3*3*4 = 36

2) For letter part, we will take the letter with the highest exponent. So, we will take w⁴.

3) Final answer is 3*3*3*4w⁴ = 36w⁴

For the table below, determine the function rule, and find each of the missing y-values.

anygoal [31]

The answer is 8 and 13

<span>
y = ax + b
y = 4, x = 1 </span>⇒ 4 = a + b
y = 6, x = 3 ⇒ 6 = 3a + b

Solve the system of equation:
a + b = 4
3a + b = 6
______
b = 4 - a
3a + b = 6
______
3a + 4 - a = 6
2a + 4 = 6
2a = 6 - 4
2a = 2
a = 2/2 = 1
b = 4 - a = 4 - 1 = 3

So, the function rule is: y = x + 3

Thus, if x = 7, then y = 7 + 3 = 10
If x = 10, then y = 10 + 3 = 13

x y
1 4
3 6
4 7
5 8
7 10
10 13

marshall27 [118]

Answer:

$\large\boxed{(t\times s)(x)=4x^3-28x^2+3x-21}$

Step-by-step explanation:

$s(x)=x-7\\t(x)=4x^2+3\\\\(t\times s)(x)=t(x)\times s(x)\\\\\text{Substitute:}\\\\(t\times s)(x)=(4x^2+3)(x-7)\\\\\text{use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(t\times s)(x)=(4x^2)(x)+(4x^2)(-7)+(3)(x)+(3)(-7)\\\\=4x^3-28x^2+3x-21$
