Answer:
4 - 3r
Step-by-step explanation:
D is just a statement of words, completely unrelated to math. C is an equation since because of the product and equal sign. hope that makes sense.
To solve this, you need to subtract 28 from both sides, then solve.
y=x^2+3x-28
The x-intercepts are (-7,0) and (4,0)
2y = -6x + 42.....in y = mx + b form, the m stands for the slope
y = -6/2x + 42/2....reduce
y = -3x + 21.....so the slope is -3
Answer:
a^2+b^2=c^2
Step-by-step explanation:
a, b, c each represent a side. Lets say a triangle has a=2 and b=4.
- a^2= 2^2= 2*2= 4 do the same with B.
b^2= 4^2= 4*4= 16
2. a^2+ b^2= 4+16= 20= c^2

Answer:
99.73%
Step-by-step explanation:
If you have a calculator with distribution functions, this problem boils down to using a single command:
norm(70.8, 85.2, 78, 2.4) = 0.9973
This tells us that 99.73% of the scores are in the 70.8-85.2 range.
