Answer:
y = -5x - 1
Step-by-step explanation:
Note that as x increases from -2 to -1, y decreases from 9 to 4, a drop of 5.
Similarly, if x increases from 0 to 1, y decreases from -1 to -6, a drop of 5.
Thus, this table represents a decreasing linear function.
The slope of this line is m = rise / run = -5 / 1, or just -5.
Using the point-slope formula for the equation of a straight line:
y -k = m(x - h). Here, the slope, m, is -5, and one point on the line is (0, -1).
Thus, we have y + 1 = -5(x - 0), or y = -5x - 1.
The "function rule" here is y = -5x - 1, a linear function.
Answer:
4 bags
Step-by-step explanation:
Step 1
1 bag = 24 oz
Hence:
1 ounce(oz) = 0.0625 pound
24 oz = x pound
Cross Multiply
x pound = 24 × 0.0625 pound
x pound = 1.5 pounds
Hence, 1 bag = 1.5 pounds
Step 2
If
1.5 pounds = 1 bag
5 pounds = x bags
Cross Multiply
1.5 x = 5 × 1
x = 5/1.5
x = 3.33 bags
At least 5 bags means exactly 5 bags or more
= 3 bags = 1.5 × 3 = 4.5 pounds
4 bags = 1.5 × 4 = 6 pounds
Therefore, he will need to buy 4 bags
at least 5 pounds
Answer:
Please post a picture of the given triangle.
Step-by-step explanation:
Answer:
C 170
Step-by-step explanation:
A = 1/2 bh
multiply each side by 2
2A = bh
divide each side by b
2A/b =h
The height of a triangle is equal to twice the area A divided by the base ,b.
