(9,3) I believe. Because to get from -3 to -9 you multiply by three, as well as 5 to 15. So you simply multiply multiply these coordinates by three.
Answer:
A (1\(3^4))
Step-by-step explanation:
3^-8\3^-4 = 3^4\3^8 =1\3^4
Answer:
y < -2/3x +4
Step-by-step explanation:
The line intersects the y-axis at y=4, so that is the y-intercept.
The line drops 2 units for each 3 units to the right, so the slope is ...
(change in y)/(change in x) = -2/3
The slope-intercept form of the equation for a line is a form you have memorized:
y = mx + b . . . . . . for slope m and y-intercept b
Using the values we read from the graph, the equation of the line is ...
y = -2/3x + 4
The line is dashed, so the inequality does not include points on the line. The solution just includes y-values less than (below) those on the line. Hence the inequality is ...
y < (-2/3)x +4
The formula for the volume of a pyramid is (1/3)area of the base x height.
And the questions gives us all the information we need! All we need to do is plug in the values.
V = 1/3 b x h
V = 1/3 x 625 x 30
V = 10 x 625
V = 6250 cubic meters
Hope this helps!
