Answer:
y=-1/3x+5
Step-by-step explanation:
<u>Slope-intercept form</u>
y=mx+b
m => slope
b => y-intercept
<u>Slope</u>
m=(y2-y1)/(x2-x1)=(5-4)/(0-3)=1/(-3)=-1/3
<u>Y-intercept</u>
y=-1/3x+b
5=-1/3(0)+b
5=b
<u>Final equation</u>
y=-1/3x+5
Answer:
Option B, 187.5 cm³
Step-by-step explanation:
Volume of the triangular prism,
base area × height
= (10×7.5/2)×5
= 187.5 cm³
I think that you multiply 2 with 4 to get 8 and then multiply 8 with 7 to get that number then add 2.75... to get the total.
Hope it helped..
Answer:
Step-by-step explanation:
Math on it's own is not hard. It's the way teachers teach it. It also could be your brain, some peoples brain (like my own) aren't made for math where there is only one answer but for creative interprutive answers like philosophy and art. Some minds are good for sports. Find what your mind is good for and you never go wrong.
Answer: 729
Step-by-step explanation:
3^-2 = 1/9

(-1)^2 = 1
1/(1/9 * 1/81 * 1)
1/ 1/729 = 729
