√-9 is 3i.
Since there is a negative in the root, you can't have a regular number as the answer.

Find the inequality represented by the graph
Answers
Answer:
y ≥ 1/2xStep-by-step explanation:
Given the following inequality, we know that y must be greater than or equal to x because the line is not dashed, and is shaded above the line.
Now to find the equation just pretend that this is just a normal linear equation, and solve for the equation.
So since the y intercept is 0, and there is a rise of 1 for a run of 2 or 1 unit up every two units to the right, the corresponding linear equation is y = 1/2x.
Now since this is an inequality where y is greater than or equal to x.
y = 1/2x → y ≥ 1/2x

Answers
Answer:
Bagels are 4 and Muffins are 2
Step-by-step explanation:
solve the system of equations
Answer:
Bagels are 4 and the muffins are 2 or the first answer
Step-by-step explanation:
2b+m=10
3b+m=14
we can subtract the equations
-b=-4
multiply both sides by -1 to get
b=4 meaning a bagel is four dollars
we can then subsitute this
2(4)+m=10
8+m=10
subtract 8 from both sides
m=2
subsitute these into the second equation to check
3(4)+(2)=14
12+2=14
14=14
Therefore the answer is Bagels are 4 and the muffins are 2 or the first answer
You have 5814 meters of rope you need to cut into 27 sections how many 27 meters secton of rope will you be able to create and how much rope will be left over as waste
Answers
Answer:
215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left
Step-by-step explanation:
we have 5,814 meters of rope and we are told to calculate the number of 27 meters sections that we can cut:
you have to divide 5,814 meters by 27 meters = 215.333
that means that you have 215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left (0.333 x 27 = 9)

Simplify::
2(x+5)>-4
Divide by 2 on both sides::

x+5<-2
Subtract 5 from both sides::
x+5-5<-2-5

Which simplified equation is equivalent to the equation shown below? 4x + -3 -9 +4x=6
Answers
Answer:
x + x = 4.5 or x = 2.25 is the answer or the value of x.
Step-by-step explanation:
4x + -3 -9 +4x=6
4x + 3 + 9 + 4x=6 + 3 + 9
4x + 4x = 18
4x/4 + 4x/4 = 18/4
x + x = 4.5
x = 2.25

Describe the graph of y = |x - 2| + 4
Answers
Answer:
Step-by-step explanation:
Note that this function resembles the absolute value function y = |x|.
The graph of y = |x| has its vertex at (0, 0) and opens up in a v-shape.
The graph of y = |x - 2| looks the same as that of y = |x|, but the entire graph has been translated 2 units to the right.
The graph of y = |x - 2| + 4 is that of y = |x - 2|, translated 4 units up.
