Answer:
Her recent math test
Step-by-step explanation:
on the math test she scored 51 out of 60 points which is 51/60. this equals 0.85 which when converted to a percentage is 85%. on the science test she scored 72 out of 90 points which is 72/90. this equals 0.8 as a percentage is 80%
For these problems you'll need to know that the volume on a triangle can be figured out by plugging in given information into the equation: v=1/2 bxh
I believe that the answer is 8
So this is using slope-intercept form (y=mx+b)
m is slope and b is the y-intercept
Looking at the graph, the line goes through the y-axis at (0,-5) so -5 is your y-intercept.
The slope of the line can be determine by using "rise over run". Find two points on the graph (I used 0,-5 and 1, -2). Count up from -5 to -2 (you get 3), count over from 0 to 1 (you get 1). Rise over run means that the slope equals 3.
Now, you just have to plug the numbers in.
Slope = 3; y-intercept = -5
y = 3x -5
The answer is A.) Y= 3x - 5
Hope this helps. Lmk if you need any more help :)
