F(x) = -52x + 4
g(x) = -12x - 4
To find the solution of the system of equation, we have to just equate the equation to each other.
f(x) = g(x)
-52x + 4 = -12x - 4
-52x + 12x = - 4 - 4
-40x = -8
x =
x = 0.2
400. Just add a zero when you're dealing with tens
Answer:
See below
Step-by-step explanation:
B) The correlation coefficient is 
, which can be determined by plugging the data into a TI-84 calculator.
C) A correlation coefficient of indicates that the correlation between the independent and dependent variable (x and y in this case) is moderately strong with a positive correlation. The closer 
is to 1, the stronger the positive correlation. The closer is to -1, the stronger the negative correlation. If is closer to 0, then there's no correlation.
Answer:
D
Step-by-step explanation:
The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).
<2 + 40 + 40 = 180 Combine the left
<2 + 80 = 180 Subtract 80 from both sides
<2 = 180 - 80
<2 = 100 degrees.
That's not the answer. We have to solve for x
<2 = x + 106
100 = x + 106 Subtract 106 from both sides
100 - 106 = x
x = - 6
