The rule for a 90 degree rotation is
(x,y)——>(-y,x)
So let’s take the coordinate (-5,-1) and let’s replace the x and y places together!!!
So that would give us -1•-1 which is just 1
Then -5•1 which is just -5
So the answer is
(1,-5)
Answer:
65
Step-by-step explanation:
so first you want to find out how fast Henry can solve the problems
26 problems in 2 minutes
that means 13 problems per minute
then 13*5=65
Answer:
m = -1
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
-13 = 5(1 + 4m) - 2m
Step 2: Parenthesis (distribute)
-13 = 5 + 20m - 2m
Step 3: Combine like terms (m)
-13 = 5 + 18m
Step 4: Subtract 5 on both sides
-18 = 18m
Step 5: Divide both sides by 18
-1 = m
Step 6: Rewrite
m = -1
Answer:
D
Step-by-step explanation:
The range of a graph is the span of y-values it covers.
From the graph, we can see that the span of y-values covered goes from y=-3 all the way to y=3.
However, note that at y=-3, while it is a closed circle, it is an open circle at y=3.
This means that we do <em>not</em> include y=3 in our range, but we <em>do</em> include y=-3 in our range.
So, our range is all values between -3 and 3 including -3.
In set notation, this is (and remember since this is the range, to use y):
So, our answer is D.
And we're done!
