Answer:
The first graph.
Step-by-step explanation:
The graph of the function y = 2x + 7, is a straight line because it is a linear function, and has y-intercept of 7 and a slope of 3; so we are looking for a graph that has these characteristics.
From the 4 graphs, we see that the 1st graph has a slope of 3 and a y intercept of 7, and thus it is the correct answer.
Step-by-step explanation:
equation y =
When x = -1
y = = (Answer)
When x = 0,
y = = 1 (Answer)
When x = 3,
y = = 216 (Answer)
Consider the word phrase "2 apples". This is the same as "2 of apples". Mathematically you could write: 2×apples or even 2a.This is exactly the type of thing you have when you write:6(−5n+7)This is the same as: 6of (−5n+7)Lets write this out in full:(−5n+7)+(−5n+7)+(−5n+7)+(−5n+7)+(−5n+7) (−5n+7)Write this as: (−5n−5n−5n−5n−5n−5n)(7+7+7+7+7+7) As you can see, we have 6 of each Giving[−(6×5)×n]+[6×7]=−30n+42
Answer:
Step-by-step explanation:
there are a total of 20 marbles and the chance that it is blue is 8/20 so multy that by itself and the answer is 4/25
The problem is 3+6x = 15 with x being the number of white numbers.
Isolate variable by subtracting 3 on both sides: 6x = 12.
Isolate variable by dividing 6 on both sides: x = 2
The number of white marbles is 2.
