Answer:
8x+3y=-6
Step-by-step explanation:
Convert to slope-intercept form
8x+3y=-6
3y=-8x-6
y=-8/3x-2, The slope is the same, therefore the lines are parallel.
Answer:
75 FT
Step-by-step explanation:
Multiple 5 by 4 for each of the three squares, then multiply 5 by 3 for each triangle and divide it by 2. Add them all together and you get 75.
I think the lowest common multiple of 12, 40, and 45, 40, and 12 would be 360
Answer:
b. 85
Step-by-step explanation:
Average grade (μ) = 75
Standard deviation (σ) = 8
Assuming a normal distribution, the z-score corresponding to the upper 10% of the test grades is z = 1.28.
The minimum grade 'X' within the top 10% is given by:

Rounding to the nearest percent, the dividing point between an A and a B grade is 85.
