To solve for x in the given equation;
We start by collecting like terms, as follows;
When a number crosses the sign of equality, the sign in front of it switches. Positive numbers becomes negative, and vice versa.
We would now have;
ANSWER:
The answer is x = -8
Answer:
2
Step-by-step explanation:
So!
If the d (discriminant)
d > 0 Then 2 solutions
d = 0 Then 1 solution
d < 0 Then none
36 > 0 so 2 solutions
assuming that all the coins are homogeneous, the probability of each coin be on heads is 1/2. so:
Answer:
f(x) = 0.625x + 3.5
Step-by-step explanation:
Linear function equation : f(x) = mx + b
plug in numbers
equation 1: 1 = -4m + b
equation 2: 6 = 4m + b
e(1) + e (2): 7 = 2b, b = 3.5
plug b = 3.5 into e(1): 1 = 3.5 - 4m, 4m = 2.5, m = 0.625
f(x) = 0.625x + 3.5
Answer:
27.69
Do not worry about the decimal point until you get your answer.
Just multiply like there is no decimal at all.
When you do get your answer, count how many decimal places are after the decimal point. In this case, we have two decimal places.
3.9
7.1
