Question:
What is the value of 
when x=3 and y=0
Answer:
The answer is zero
Step-by-step explanation:
Given:
x = 3
y = 0
Solution:
Let us first substitute the given values inb the expression
then we get
We also know that anything raised to the power of zero also give zero
then
=> 0
8. 4x²+3y = 4(4)²+3(5) = 4(16)+15 = 64+15 = 79
basically you have to substitute the variable for the given value. (ex. x is replaced by 4 and y is replaced by 5 and z is replaced by 3) FOR BOTH PROBLEMS!
9. (y+z)/x = (5+3)/4 = 8/4 = 2
Answer:
<u>3/16 of the whole pie</u>
Step-by-step explanation:
Lexi had 3/4 of an apple pie. She gave 1/4 of it to Julie. That means what Julie receives is the product of the whole and the portion.
==========================================================
Solving :
Therefore, the equation is :
⇒ 3/4 × 1/4
⇒ <u>3/16 of the whole pie</u>
Use the rule that x^(-k) = 1/(x^k) to get
(-3)^(-5) = 1/( (-3)^5 ) = 1/( -243 )
Comparing 1/( -243 ) with the form 1/x, we see that x = -243
<h3>Answer: -243</h3>
Answer:
Step-by-step explanation:
What is the average speed of a biker if she biked 4 1/4 of a mile in 25 minutes?
-----------------
rate = distance/time
-----
rate = (17/4)/(25/60) = (17/4)(60/25) = (17*3/5) = 51/5 = 10.2 mph
----------------
