The second is correct, but the first one isn’t so let’s go over it. We can see that Sunday’s high was -10 degrees and that Monday’s high was -6 degrees. Just by looking at the graph we can tell that the answer is C. This is because Monday’s high was ABOVE Sunday’s high telling us that there was an increase in the temperature and by looking we can see that it was a 4 degree increase.
The final answer for the first one is C and the final answer for the second one is correct.
Let's solve for x.
y=x−3
Step 1: Flip the equation.
x−3=y
Step 2: Add 3 to both sides.
x−3+3=y+3
x=y+3
Answer:
x=y+3
Let's simplify step-by-step.
−5x+9
There are no like terms.
Answer:
=−5x+9
Answer:
Step-by-step explanation:
In order to solve this exercise it is important to remember:
1. The Negative exponent rule, which states that:
2. The Product of powers property, which states that:
Therefore, knowing the explained above and having the following expression provided in the exercise:
You can identify that the numerator and the denominator have the same base 2. Then, you can simplify the expresssion as following:
Answer: Third option.
Step-by-step explanation:
To solve this exercise it is important to remember the following:
1) By definition, equivalent expression have the same value, but they look different.
2) The multiplication of signs:
Then, given the following expression provided in the exercise:
You need to distribute the postive sign:
And finally, you must add the like terms:
As you can notice, the expression obtained matches with the expression shown in the third option.
X^2-2(x-y)-z^3
First we substitute the variables for their known values and get
2^2-2(2-(-2))-(-3)^3
Simplify
4 + (-4+4) -(-27)
4+-27= -23
That’s your answer
