Answer:
h(0) = -4
Step-by-step explanation:
Step 1: Define
h(x) = -3x - 4
h(0) is x = 0
Step 2: Substitute and Evaluate
h(0) = -3(0) - 4
h(0) = 0 - 4
h(0) = -4
I think it’s the first one
Sorry if I’m wrong
Answer:
7.21 units
Step-by-step explanation:
The shortest length needed to connect the house to the existing pipeline is the perpendicular distance between the location of the house (2,9) and the line y = 2/3x - 1.
The perpendicular distance (d) between a point (
) and the line Ax + By + C = 0 is given as:
The line is given by y = 2/3 x - 1; 2/3x - y - 1 = 0. The point = (2, 9)
hence A = 2/3, B = -1, C = -1, 
. Therefore:
The unit rate is obtained by dividing the amount of work done by the unit time. In the problem, we are already given the total number of parts manufactured (amount of work done) and the total amount of time to manufacture (7 hours).
Obtaining the unit rate is as simple as dividing 1116 parts by 7 hours, as shown below:
Unit rate = 1116 parts / 7 hours
Unit rate = 159.42857
Therefore the unit rate is approximately 159 parts/h.
Answer:
B. 30
Step-by-step explanation:
the equation looks like 22 - x = -8 and 22 - 30 is negative 8
