Answer:
8.9
Step-by-step explanation:
The rules for rounding are if the number is 5 or higher, round up. If it is 4 or lower, round down.
Answer:
y=20x
Step-by-step explanation:
do do I intercept a zero, so you don't have a "b"
The slope is 20. that's pretty self-explanatory
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)
To find "m", you can use the slope formula and plug in the two points:
(2,3) = (x₁ , y₁)
(0,9) = (x₂ , y₂)



m = -3
y = -3x + b
To find "b", you can plug in one of the points into the equation (however they already gave you the y-intercept (0,9) or 9)
(2,3)
y = -3x + b
3 = -3(2) + b
3 = -6 + b
9 = b
y = -3x + 9
Answer:
Technically he isn't, but he is off by only 0.5 cm.
Step-by-step explanation:
To check, we can use pythagorean theorem:
22.8^2 + 13.82^2 = about 22.6
However, Mr. Lim got it as around 26.1
