Two points determine a line. In slope intercept form we have:
y = -2x + b
So:
-12 = -2(3) + b and [first equation]
k = -2(6) + b [second equation]
We have a system of simultaneous equations with two unknowns. The first is trivially easy to solve:
-12 = -6 + b [Evaluate -2(3)]
-6 = b [Add +6 to each side]
So we substitute this into the second equation:
k = -2(6) + -6 = -18
We could double check our work knowing that m=Δy/Δx
We expect m to be -2. Does:
-2 = (-18 - -12)/(6 - 3) = -6/3 = -2?

<span>24=6−2(2n+3)
24 = 6 - 4n - 6
4n = -24
n = -6
answer
n = -6 </span><span>makes the equation true</span>
Answer:
$26.88
Step-by-step explanation:
33.60x.20=6.72
33.60-6.72= 26.88
½ × 2 = 1
½ × 3 = 3/2
½ × 4 = 2
½ × 5 = 5/2
The number of times which the number 2 x 10-5 is greater than 4 x 10-12 is; 5 × 10⁶ times
To estimate how many times larger 2 x 10-5 is than 4 x 10-12 in the form of a single digit times an integer power of 10;
We must evaluate as follows;
- 2 x 10-5 divided by 4 x 10-12
Therefore; we have;
Since we are required to express the answer in the form of a single digit times an integer power of 10; we have;
