Four less than nine times a number is one hundred twenty-two. Find the original number.
Tasya [4]

Answer:

The number is 14

Step-by-step explanation:

Denote the original number by z. The expression "Four less than nine times a number is one hundred twenty-two" can be rewritten in an equation.

Our number is z, then the left hand side of the equation is 9z-4.

The right side of the equation is 122. Then the complete equation is 9z-4=122. Add 4 in both sides to get 9z=122+4=126. Now, divide by 9 in both sides to get z=\frac{126}{9}=14

Which equation best represents a trend line for the scatter plot?
kvasek [131]
Y = (-3/7)x + 4

Looking at the graph, you can see the trend line plotted. And conveniently, there are a couple of points on the trend line that are indicated. Those points being (0,4) and (7,1). The equation of a line in slope intercept form is:y = ax+b

Looking at the points available, the point (0,4) already gives us the y intercept since x is equal to 0. So our equation becomes:
y = ax + 4

Now we need to determine a which is the slope. The slope is the change in y divided by the change in x. So let's do that
(1-4)/(7-0) = -3/7

And now our equation becomes:
y = (-3/7)x + 4

And given formatting issues, the first option available is the correct one.
