Answer:
It does
Step-by-step explanation:
It does have a proportional relationship because if you try to find the relationship between the first two inputs and outputs, you can find that it is 21 (1 to 21, 21 divided by 1 would be 21) then if you use that relationship with the other numbers (times 21) you would get the same answer. For example in the second one, the two numbers are 2 and 42, 2 times 21 would equal 42. The next one would be 3 times 21 to equal 63 and etc.
Hope this Helps!!
Answer: 15 students
Step-by-step explanation:
From the question, we are informed that there are 150 students in 6th grade, and that 10% earned straight As last quarter.
The number of students that earned straight As will be:
= 10% × 150
= 10/100 × 150
= 0.1 × 150
= 15 students
Answer:
Again, the answer is (1,-2)
Step-by-step explanation:
Substitute the values
Answer:
1924.3
Step-by-step explanation:
Ok
You need to write an expression for the change in value
the change is linear, so you will get a line equation y = mx + b
y-axys : value
x-axys : years
New Hampshire:
Slope =
the y-intercept will be 37600 because you can assume that 1950 = 0, and 2000 = 50
y = 1914*x + 37600
Massachussets:
Slope =
Same as above, the y-intercept is 55400
y = 2606*x + 55400
Now you need to equal the value for both and find the year "x"
1914x + 37600 = 2606x + 55400
- 692x = 17800
x = -25.7
Since i considered x = 0 to be 1950; the actual year is 1950 - 25.7 = 1924.3
