Answer:
x=9
Step-by-step explanation:
This is because you need to follow the DCMAM steps. Start with 8.88 divided by 4.44 which is 2. then add 7. then you get x=9
Answer:
x = 9
Step-by-step explanation:
B. Find the solution set of x and describe how you would graph it on a number line.
Answer:
The written form would be "Nine more than three times a number is greater than -18.
Step-by-step explanation:
To graph it, you must first solve for x.
3x + 9 > -18
3x > -27
x > -9
Now we can graph this by putting an open dot at -9 and then drawing an arrow to the right.
y = 0 + 3.2t
Part a:
Identify the y-intercept of the regression line and explain what it represents in the context of the data.
Answer:
The y-intercept is zero and it means that in the year 1993 there was no change in the seawater level.
Step-by-step explanation:
See the scatter plot graph attached.
It represents the change in global sea level from 1993-2017, according to the National Aeronautics and Space Administration (NASA).
The equation of the regression line is written below, where Y represents the predicted change in sea level in mm and t represents the years since 1993.
y = 0 + 3.2t .............. (1)
Therefore, the equation is in the slope-intercept form and the y-intercept is zero for this graph.
That means in the year 1993 there was no change in the seawater level. (Answer)
