- 9x² + 6x + 4 = (9x² + 6x + 3) + 1 = 3(3x² + 2x + 1) + 1 = 3y + 1
Answer:
what is the follwing adverb???
ummmmmmmm.....
Answer:
y = (3/2)x - 5/2
Step-by-step explanation: 5 + 2x
-2x-3y=5, solved for y, is y = ------------- , with a slope of -2/3. A line
-3
perpendicular to this one has a slope which is the negative reciprocal of -2/3, that is, +3/2. Using the slope-intercept formula, we calculate the y-intercept of the line that is perpendicular to the given one and passes through (1/3, -2): y = mx + b => -2 = (3/2)(1/3) + b, or
-2 = 1/2 + b. Thus, b must be -2 1/2, or -5/2.
The desired equation is y = (3/2)x - 5/2.
Answer:
2/3
Step-by-step explanation:
Let n = the repeating, non-terminating number 0.666...
We now have n = 0.666666...
We want the number n in the form of a fraction.
Since only 1 digit repeats, the 6, use a 1 followed by 1 zero, which means the number 10. Now multiply both sides by 10 and write the original equation below it.
10n = 6.666666...
n = 0.666666...
Subtract the bottom equation from the top equation.
9n = 6
n = 6/9
n = 2/3
