The domain is the input of the function or n in this case. So, in the boxes, you would put [1, 2, 3, 4, 5, 6, ...]

The range is the output of the function or f(n) in this case. So, in the boxes, you would put [4, 6, 8, 10, 12, 14, ...]

I have to find slope-intercept equation

adoni [48]

Answer:

y = 4x - 9

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

the y-intercept is when the line crosses the y axis, and in this case we can see it at "-9"

The slope we can do rise over run "r/r" ot "y/x"

r/r = 4/1 = 4

The line is positive since its going up

y = 4x - 9

Hope this helped!

Plot the point (−12, −52) on the coordinate plane.

irinina [24]

Answer:

Step-by-step explanation:

-12 goes on the x axis (the line that goes ⇄), and because it's negative, it will go to the right.

start from that point (-12 on the x axis) and start going down till you reach -52 on the y axis (the line that goes ⇅)

so it should end up in the bottom left part of the graph

Answer:

Proved

Step-by-step explanation:

$cos^4\alpha +sin^4\alpha =\frac{1}{4}(3+cos4\alpha )\\\\$

Take the Left Hand Side:

$cos^4\alpha +sin^4\alpha\\\\(cos^2\alpha )^2+(sin^2\alpha )^2\\\\(\frac{1+cos2\alpha }{2})^2+(\frac{1-cos2\alpha }{2})^2 \\\\\frac{1+2cos2\alpha +cos^22\alpha }{4}+\frac{1-2cos2\alpha +cos^22\alpha }{4} \\\\$

$\frac{1+2cos2\alpha +cos^22\alpha +1-2cos2\alpha +cos^22\alpha }{4} \\\\\frac{2+2cos^22\alpha }{4} \\\\\frac{1+cos^22\alpha }{2} \\\\\frac{1}{2}(1+cos^22\alpha )\\\\$

$\frac{1}{2}(1+\frac{1+cos4\alpha }{2})$

$\frac{1}{2}(\frac{2+1+cos4\alpha }{2})\\\\\frac{1}{4}(3+cos4\alpha )\\\\$

Hence Proved!

Plz answer this question and I will mark you as brainliest

tangare [24]

Answer: 3/8

Step-by-step explanation:

When you subtract fractions, you want them to have a common denominator.

$\frac{36}{24}-\frac{27}{24} =\frac{9}{24}$

This answer is correct, but it is not in the simplest term. To get the simplest term, you want to divide the numerator and denominator by the same number.

$\frac{9}{24} =\frac{3}{8}$
