Mathematics
1 answer:
lisov135 [29]3 years ago
5 0
The prime factorization of 18 is: 2 x 3 x 3.
The prime factorization of 45 is: 3 x 3 x 5.
The prime factors and multiplicities 18 and 45 have in common are: 3 x 3.
3 x 3 is the gcf of 18 and 45.
gcf(18,45) = 9.

Can someone show the steps to factor 15x^x y^2 – 3x^3 y+75x^4
umka21 [38]
Step 1- Find the Greatest common factor (GCF)
GCF = 3
Step 2-  Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3(15x^xy^2/3 + -3x^3y/3 + 75x^4/3)
Step 3- Simplify each term in the parentheses 
3(5x^xy^2 - x^3y + 25x^4)

Find the solution set for the given inequality. -7x + 3 > 45 A) Show your work to solve this inequality (B) Graph the solutio
scoundrel [369]

Answer:

See explanation

Step-by-step explanation:

Given the inequality -7x+3>45

A) Add -3 to both sides of inequality:

-7x+3-3>45-3\\ \\-7x>42

Divide by -7 (remember, dividing the inequality by negative number changes the sign of inequality):

x

B) Plot open circle at -6 on the number line and shade all values of x which go to the left from -6 (see attached diagram).

What is t+1/5=t+7/8? What is the value of t? There should be 2 values and the slashes are fractions
muminat
There is NO solution.

Cancel t on both sides (1/5 = 7/8).

Since 1/5 = 7/8, that doesn't make any sense so that is inapplicable ( So NO answer).
