Answer: B
Step-by-step explanation:
The green ball
Speed=Distance/Time
White ball 143/4=35.75
While green ball 112/3=37.33
37.33>35.75
Answer:
68
Step-by-step explanation:
I'm going to assume you meant "what is the value of f(g(-2))?"
g(-2) = 5(-2) + 4 = -6
f(-6) = 8 - 10(-6) = 68
No. 61 is an odd number not divisible
Answer:
x=-3, x=1, x=8
Step-by-step explanation:
When you have to find the zero of an equation like (x+3) all you have to do is solve for x.
x+3=0 equal the equation to zero
x+3-3=0-3 cancel out 3
x=-3 answer
If you have to find the zero of an equation like f(x)=-2x^2 - 5x + 7 then you would have to factor the equation.
7*-2=-14 multiply
-7 & 2 find the two numbers that when multiplied =14 and when added = -5
(2x^2 + 2) (-7x + 7) replace -5 with -7 & 2
-2x (x - 1) -7 (x - 1) factor
(x - 1) (-2x - 7) rewrite
1st: x - 1 = 0
x = 1 : Answer
2nd: -2x - 7= 0
-2x - 7 + 7 = 0 + 7
-2x = 7
-2x / -2 = 7 / -2
x = 7 / -2 : Answer
<u>Answer:</u>
The point-slope equation of the line is or
<u>Solution:
</u>
Let us assume that the slope is m and the y intercept of the line is b
Hence, --------- (i)
y intercept means we need to find the value of y when x is 0
Here the line passes through point (4,-6) and slope m = (-2)
Now putting the point (4,-6) in equation (i) we get,
So, the equation of the line will be will be or
