Answer:
y = 3x + 4
Step-by-step explanation:
slope = (y2 -y1)/(x2 - x1)
y2 = 19
y1 = 7
x2 = 5
x1 = 1
Slope = (19 - 7)/(5 - 1)
slope = 12 / 4
slope = 3
So far what you have is
y = 3x + b To solve for b, use either of the two points.
x = 1
y = 7
7 = 3(1) + b
7 = 3 + b
b = 4
The final equation is
y = 3x + 4
We should check that with the other point
x = 5 Find y
y = 3(5) + 4
y = 15 + 4
y = 19 Ans it checks.
The <em>correct answer</em> is:
B) precise
Explanation:
Precision can be broken down into two pieces:
<em>Repeatability </em>- The variation observed when the same person measures the same thing repeatedly with the same device.
<em>Reproducibility</em>: The variation observed when different people measure the same thing using the same device.
If two measurements are very close to each other, this gives repeatability. If the measurements were made by different people, this gives reproducibility.
<em>Accuracy</em>, however, describes the difference between the measurement and the thing's actual value. This would not involve getting the same result repeatedly; it would be getting the <em>correct</em> value.
Put them into y=mx+b
y=1/3x -1
y=2/3x-4
Graph them. Where they touch is your answer. No touch? No solution. Same line? Infinite solutions.
Second set: Same thing.
Solution to first set is (9,2)
Multiply both variables individually by the multiplied variable (x)... and you find yourself with -fx + hx.... Remember to bring that negative integer along too or the answere that I have without a negative integer won't count... I hope this clarified your understanding and question. As always good spiruts
Answer:
<span> (x + 6) • (x + 5) • (x - 2)
Is this what u were looking for? Sorry if not XDD
