Answer:
1) r >-5 2) x >9
Step-by-step explanation:
So the way to answer this question is to convert minute to seconds
We know that a minute has 60 seconds
The problem states that the hummingbird flaps its wings 80 times per second
So 80 times per second x 60 seconds = 4800 times would be the final answer.
Answer:
B
Step-by-step explanation:
Absolute value works like this.
For any number you put inside the absolute value bars, it will always come out positive, so -5 and 5 can work.
The solution to the system of equation is (-4 , 2) , Option A is the right answer.
<h3>What are System Of equation ?</h3>
A set of equation whose factors are common are called system of equations.
It is given in the question
3x +5y = -2
3x +7y = 2
On solving this we get
-2y = -4
y = 2
On substitution in any equation
x = -4
Therefore solution to the system of equation is (-4 , 2) , Option A is the right answer.

X2/y+x2/
x=6
y=-4
z=-2
6✖️2/-4➕6✖️2
6✖️2=12
This goes for both due to PEMDAS
Now it looks like this:
12/-4➕12
-4➕12= 8
Now it looks like this:
12/8
Since there was no z then -2 wouldn’t be needed
So your answer would be 12/8
Hope this helps! :3
