Answer: y=x+2
Step-by-step explanation:
You can put 10 in the equation:
-10^2 -3*10 = -100 -30 = -130
Answer:
1. 27
2.6
Step-by-step explanation:
1.
remember the priorities of operations :
1. brackets
2. exponents
3. multiplications and divisions
4. (and truly last) additions and subtractions
so,
16 + 14÷2 + 3×5 - 11 =
16 + 7 + 15 - 11 = 23 + 4 = 27
2.
5 coins are tossed at the same time.
each coin has a result (head or tail).
but the observed event is the sum of all tails that show when tossing the 5 coins.
so, the possible outcomes are
0 tails
1 ...
2 ...
3 ...
4 ...
5 tails
so, in total, 6 different possible outcomes.
Answer:
B
Step-by-step explanation:
The question says reflection across y = 1 so first find this line on the graph. It will be a horizontal line.
The Y axis is the vertical axis and so the 1 is the line right above the X axis.
So to reflect, it will be the same number away from the line when reflected as when it began on the opposite side of the line. So, S is one under the reflection line so it will be one above making its new point ( 2 , 2 )
Q is right on the line so it will not move.
R is two above the line so it will now be two below the line to have ( 3 , - 1 )
