The slope of the line is - 2<br> O True<br> O False
aniked [119]

Answer:

<h2><u>FALSE</u></h2>

Step-by-step explanation:

To find the slope you need to pick two points. Points (2,4) and (4,3) are the points I used. (It does not really matter what points you chose). Now we have to follow the formula to find the slope. The formula can be seen below

Slope (m) = ΔY/ΔX

Now solve

ΔX = 4 – 2 = 2

ΔY = 3 – 4 = -1

Once you have solved it, you take it and make it a fraction

-1/2 = -0.5

NeX [460]

Answer:

Step-by-step explanation:

There's 24 students so I would do 5 × 24 which equals 120 so 420 - 120 is 300. Then 2 × 24 is 48. Now 300-48 is 252. They would have $252 left.

SOMEONE PLEASE HELP I will mark you BRAINLIST
Lana71 [14]

Answer:

27 degrees

Step-by-step explanation:

We are given that Angle AEF is 63. We can also see that EAF is a right angle. Since angles in a triangle add up to 180, we can use this to solve for AFE:

Angle AEF + EAF + AFE = 180

63 + 90 + AFE = 180

153 + AFE = 180

AFE = 27

<em>Or we can solve it another way</em>

Since EAF is a right angle, the other angles are complementary (they add up to 90) so...

Angle AEF + AFE = 90

63 + AFE = 90

AFE = 27

DochEvi [55]

Answer:

Step-by-step explanation:

a_{n}=a_{1}r^{n-1}\\0=848(0.75)^{n-1}\\or~(0.75)^{n-1}=0\\0.75

or~n \rightarrow 1+\infty\\or~n \rightarrow \infty

Hence lake will never be free of pesticide.
