Answer:
a. 3x + 22
b. slope is 3, y intercept is (0,22) this means points on graph rise 3 and run 1, this also means that in zero more weeks Daniel will have 22 hours of volunteering
c. 70 hours
Step-by-step explanation:
a. the slope is 3 so the coefficient and variable will be 3x, y intercept is (0,22) so the term would be + 22 together this is y=3x+22
b. just count points going up and horizontally for slope and y intercept is when x equals zero
c. look on the graph, the point is (16,70) in 16 weeks he will have 70 hours done
Answer:
30
Step-by-step explanation:
10x = 10*3 = 30
Answer:
b, x = 17
Step-by-step explanation:
A right angle (as shown by the box in the corner of the angle) is 90°.
So, the two angles have to add up to 90°.
22 + 4x = 90
Subtract 22 from both sides.
4x = 68
Divide both sides by 4.
x = 17
The answer is b, 17

Answer:
B: This relationship is not a function because more than one amount of plant food remains each day
Step-by-step explanation:
It is given that Ryan did an experiment by observing the effects of plant food and the growth of the sprouting bean plant. He made a note of the height of the bean plant and the amount of food remaining in the container for the plant after feeding each day.
Thus he observed that the plant food in the container decreases by an equal amount everyday as the bean plant grew. Thus this states that it is not a function between the two as there are more than one plant food remaining each day for the plant.
A relationship is a function when one element belongs to one thing.

Answer:
A. r = (-6/7)t +2
B. f(-7) = 8
C. t = -35
Step-by-step explanation:
A. To solve for r, undo what is done to r.
7r +6t = 14 . . . . . . given
7r = -6t +14 . . . . . subtract 6t
r = -6/7t +2 . . . . . divide by 7
f(t) = -6/7t +2
__
B. f(-7) = (-6/7)(-7) +2 = 6 +2
f(-7) = 8
__
C. (-6/7)t +2 = 32
-6/7t = 30 . . . . . . subtract 2
-6t = 210 . . . . . . . multiply by 7
t = -210/6 . . . . . . divide by -6
t = -35
