Answer:
In order to go from the first point to the second, we need to rise from 4 to 7, i.e. by 3. We also need to run from -4 to -2, i.e. by 2. Therefore the slope is 32 .

Answer:
(1/2) * A + (1/2) * B <= 100; for A => 50; for B => 20
(5000) * A + (30000) * B <= 1500000; for A => 50; for B => 20
Step-by-step explanation:
There are two inequalities in mind, the first of the surface and the second of the price. Always bearing in mind that the minimum are 50 of A and 20 of B.
The first
A occupies 1/2 m and B occupies 1/2 m of surface, and the limit is 100 m of surface. Thus:
(1/2) * A + (1/2) * B <= 100; for A => 50; for B => 20
The second:
A costs 5,000 and B costs 30,000, and the limit is 1,500,000. Therefore:
(5000) * A + (30000) * B <= 1500000; for A => 50; for B => 20
Is there any multiple choice answers?
Answer:
<em>f of x equals negative one third x plus 5</em>
Step-by-step explanation:
<u>Question 1
</u>
We know the line contains the point (a,b)=(0,1) and has a slope m=0
We can find the equation of a line knowing both parameters by using
y-b=m(x-a)
y-1=0(x-0)
This is the required equation of the line
y=1
<u>Question 2
</u>
The student is running a 5-Km race. Les's set x as the time in minutes. 3 minutes are needed to complete one Kilometer, so every single minute will be enough to run 1/3 Km. Every x minutes, the distance will be
Since the runner needs to complete 5 Km in total, the distance still to complete will be
This is the required function. It can be written as
"f of x equals negative one third x plus 5"
