Step-by-step explanation:
the second option 1/(125n¹²)
why ?
when we have the exponent of an exponent, we can multiply the exponents.
so, 4×-3 = -12
a negative exponent means 1/... (with the corresponding positive exponent in the denominator).
and an exponent of the multiplication of factors means that the exponent is to be used for every factor in the multiplication.
so, the exponent -3 has to be applied to 5 and to n⁴.
this gives us 5^‐3 and n^-12 as factors.
the result is 1/(5³) × 1/(n¹²).
and that is the mentioned result above.

Answers
Answer:
1. k=-9
2. a=-12
Step-by-step explanation:
1. -12(k+4)=60
use distributive property
-12k-48=60
add 48 to both sides
-12k=108
divide both sides by -12
k=-9
2. 8(3a)=9(2a-4)
use distributive property
24a=18a-36
subtract 18a on both sides
6a=-36
divide both sides by 6
a=-12

Answer:
[tex]x=22[/tex]
Step-by-step explanation:
Because [tex]\angle ABC=\angle ABD+\angle DBC=80^{\circ}[/tex], we have that [tex](2x+4)+(2x-12)=80[/tex].
Combining like terms on the left side gives [tex]4x-8=80[/tex].
Adding [tex]8[/tex] to both sides gives [tex]4x=88[/tex].
Dividing both sides of the equation by [tex]4[/tex] gives [tex]\boxed{x=22}[/tex].
2x - 12 + 2x + 4 = 80
4x - 8 = 80
+ 8 = + 8
4x = 88
Divide by 4
x = 22

Vladimir is looking to retire in 10 years. He has a plan to put $25,000 into an investment today that earns interest at a fixed amount per year. What would be a reasonable domain and range for a function modeling the total amount of the investment, including interest?
25 Points for the correct answer
Answers
The domain and range for a function modeling the total amount of the investment, including interest are as follows;
Domain, X = {0<= years <= 10}Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + 10R)}The starting principal amount, P is $25,000.
Let the interest rate per year, be represented as, R (%)Time of investment, T = 10 yearsIn essence, after 10 years, the total amount Vladimir has is;
Total amount = 25,000( 1 + xR).In essence, the domain (No. of years ) is;

Answers
Answer:
y = -4
Step-by-step explanation:
-8y+6(y+5) = 38
-8y + 6y + 30 = 38
-2y + 30 = 38
-2y = 8
8 / -2 = -4
y = -4
Answer:
V= -4
Step-by-step explanation:
-8v+6(v+5) = 38
-8v+6v+30 = 38
-2v = 38-30
-2v = 8
v = 8/-2
v = -4

The difference of the given expression is 3/20 x - 3.
Given that, (2/5x−1)−(1/4x+2).
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Now, (2/5x−1)−(1/4x+2)
= (2/5 x - 1/4 x) -1 - 2
= (8/20 x - 5/20 x) - 3
= 3/20 x - 3
Therefore, the difference of the given expression is 3/20 x - 3.

Answers
Answer:
Equation: y = -1x + 4
Step-by-step explanation:
In order to create an equation, you need to put it in slope-intercept form ( y = mx + b ). The best way to figure out to create your equation is to graph the points. 'Y' means the y-axis. 'mx' refers to the slope of a particular line and b is concluding where the line crosses the y-axis.

Write the slope intercept form of the equation for f the line through the given points
Answers
Answer:
y = -2x - 4
Step-by-step explanation:
First, I'll find the slope by subtracting the y-values and x-values of each point from each other, as shown below:
(-2 - (-4))/(-1 - 0) = 2/-1 = -2
We already have the y=intercept: (0, -4). From this, we can write a y = mx + b (slope intercept form) equation, with m being our slope and b being our y-intercept. It looks like y = -2x - 4.
