Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
−4y+4y+2=2
Step 1: Simplify both sides of the equation.
−4y+4y+2=2
(−4y+4y)+(2)=2(Combine Like Terms)
2=2
2=2
Step 2: Subtract 2 from both sides.
2−2=2−2
0=0
Answer:
All real numbers are solutions.
I think it is the second one, zero slope :)
90-20 leaves 70 for surfing. since surfing is 5 per hour, 70/5=14 hours she can surf.

Step-by-step explanation:
The coin is to be flipped 2000 times.
The probability of getting a head is 0.3.
It is given that, we need to get a head in between 575 and 618 times.
If we will get 575 heads then we will get (2000 - 575) tails.
Hence, if we take that we want to get n times head, then we will get (2000 - n) times tail.
The probability of not getting a head is (1 - 0.3) = 0.7.
The probability of getting n times head is 
.
The required probability is ∑ , where 
.
Answer:
y = 3/2 x + 9
Step-by-step explanation:
take the two points and find slope :
12 - 3 / 2 - (-4) = 3/2
then use the slope and one of the points to find the y-intercept :
y = 3/2 x + b
3 = 3/2 * (-4) + b (Substitute)
3 = -6 + b (Multiplication)
3 + 6 = -6 + b + 6 (Addition)
b = 9
so, your final slope-intercept equation is :
y = 3/2 x + 9
