Answer:
The correct answer is b) x - y + 1 = 0
Step-by-step explanation:
In order to find this, start by finding the slope using the two points given.
m(slope) = (y2 - y1)/(x2 - x1)
m = (5 - 2)/(4 - 1)
m = 3/3
m = 1
Now that we have the slope, we can plug into point slope form along with either point. Then we can solve for 0 to see which equation is correct.
y - y1 = m(x - x1)
y - 2 = 1(x - 1)
y - 2 = x - 1
-x + y - 2 = -1
-x + y - 1 = 0
x - y + 1 = 0
Answer:
B. False
Step-by-step explanation:
A moderate positive correlation, e.g. r = 0.5 or 0.6, shows that there is some relationship between driving faster and accidents that result in more severe injuries. But that relationship is not very strong or solid and can result from other variables being involved or simply randomness. You cannot affirm that X causes Y if the correlation is not strong.
Solution-
The answer is 3 because an equilateral triangle has 3 equal sides and therefore there are 3 equal angles.
Each equal angle contains an arc of equal length.
so the answer is 3 that is option A is correct.
Answer:
3.643 X 10 -1
Step-by-step explanation:
Hello :
f(-4) = 4(-4)+9 = -7
f(-2) = 4(-2)+9 = 1
f(0) = 4(0)+9 = 9
f(2) = 4(2)+9 = 17
the range of the function f(x) = 4x + 9 is : <span>D' = {-7, 1, 9, 17}</span>
