Answer: f(0)= -4, f(5)= 15, f(-3)= -7
Step-by-step explanation:
0 < 1, so plug into x-4. 0-4=-4
5> 1, so plug into 3(x). 3*5=15
-3<1, so plug into x-4. -3-4=-3+(-4)= -7
Answer:
an inequality symbol means either>or<so in this question 4 u use x<12
Answer:
C. 3(2x + 5y) is the algebraic expression equivalent to the expression
Step-by-step explanation:
From the question, the given expression is 6x + 15y.
Factorizing this expression gives 3(2x + 5y). Hence, the algebraic expression equivalent to the expression 6x + 15y is 3(2x + 5y). (Option C).
Checking the remaining options
A. 3(2x - 5y)
Expanding this gives 6x - 15y. It is not equivalent to the given expression
B. 3(5x - 2y)
Expanding this gives 15x - 6y. It is not equivalent to the given expression
D. 3(5x + 2y)
Expanding this gives 15x + 3y. It is not equivalent to the given expression.
Hence, C. 3(2x + 5y) is the algebraic expression equivalent to the expression.
The answer would be 31 in.
First do the Pythagorean theorem.
225+ 729= 954
Then find the square root of 954 which is 30.88 repeating, so round up to 31 in.
