So, you know that x=-7 and y=3, and you have the expression x - y^3, and when the question says "evaluate"(in this context) it means simplify into the smallest amount of terms possible. So you substitute what x is equal to into the expression and the same for y. so you get (-7) - (3)^3. Then you use pemdas to simplify.
Answer:
2,-12
Step-by-step explanation:
The given equation is ,
We know that modulus only gives positive value , Therefore on squaring both sides we have ,
Answer:
The top right graph.
Step-by-step explanation:
If you find the mean for all the graphs you get:
Graph 1: 7 Graph 2: 2
Graph 2: 7 Graph 4: 7
To find the mean you all all the numbers up and divide it by the number of data points for example heres the first graph:
8 + 8 +8 +8 +8 +8 +1 = 49 Add the data points
49 / 7 = 7 Divide by the total amount of points which is seven
