bearing in mind that the LCD in this case for those two denominators is 40, so let's use that for the sum

Answer:
x = 0, 1
Step-by-step explanation:
f(x) = g(x)
0.25^x = -0.75x + 1
Move all terms to the left side and set equal to zero
0.25^x +0.75x -1 = 0
slove for x and you'll get x = 0, 1
Answer: See picture
Step-by-step explanation:
For this problem, we need to know how to graph the inequality. First, let's establish that we will have a solid line because the inequality is greater than or equal to. If the inequality was only greater than, then it would be a dotted line. For -4/3x-7, you would start at (0,-7) as the y-intercept. Then you would go down by 4 and go to the right by 3 units. Now, we have to do shading. Since we know that y is greater than or equal to, the shading will be on top of the line, where y is greater.
Answer:
-4
Step-by-step explanation:
The formula of an arithmetic sequence is nth term=a+(n-1)d. First term is a and common difference is d.
Let's plug our info in.
-20=12+(9-1)d
-20=12+8d
Subtract 12 from both sides.
-32=8d
Divide both sides by 8.
d=-4
Have a wonderful day! :D
