Step-by-step explanation:
Y= x - 2. Y = 3x + 5
Putting value of y
x - 2 = 3x + 5
-2 - 5 = 3x - x
-7 = 2x
-7/2 = x
Putting value of x
Y = 3(-7/2) + 5
Y = - 10.5 + 5
Y = - 5.5
Answer:
0.68, 68/100 or 17/25, and 17:25
Step-by-step explanation:
Answer:
<em>4 + 7x – 2</em>
Step-by-step explanation:
<u>Equivalent Expressions</u>
Let's find out which expressions are equivalent by simplifying them. One of the expressions should be not equivalent to the other three.
Simplifying
Now for the second expression
The third expression simplifies to
Finally, this is the simplification for the expression
As seen, the only expression not equivalent to the other three is 4 + 7x – 2
Answer: −3(5c+4)(5c−1)
Step-by-step explanation:
1. Find the Greatest Common Factor (GCF).
GCF=3
2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3(75c^2/3+45c/3−12/3)
3. Simplify each term in parentheses.
−3(25c^2+15c−4)
4. Split the second term in 25c2+15c−4 into two terms.
−3(25c^2+20c−5c−4)
5. Factor out common terms in the first two terms, then in the last two terms.
−3(5c(5c+4)−(5c+4))
6. Factor out the common term 5c+4
−3(5c+4)(5c−1)
The answer is X = 4, 2
You can even plug those in for X to check your answer.
