Answer:
Step-by-step explanation:
B
Answer: Check the attached
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
The linear functions have the form y=mx+b
where m is the slope and b is the y- intercept
Therefore, you have:
1) The slope -6/5 and b=(0,8) is:
y=(6/5)x+8
2) You have 3x-2y=1. Then, you only have to clear y:
y=(3/2)x-1/2
Answer:
tons.
300 times.
Step-by-step explanation:
Last year, the world produced 3.5 billion tons of cement and that amount could increase by a billion tons by the year 2050.
So, the net production of cement by the year 2050 will be (3.5 + 1) = 4.5 billion tons i.e.
tons. (Answer)
Now, this amount is larger than
by
times. (Answer)
