a^15 ÷ a^5 = a^10

a÷a = a

15- 5 =10

give brainliest please I need it to level up

Answer:

True

Step-by-step explanation:

Using the rule of exponents

[tex]\frac{a^{m} }{a^{n} }[/tex] = [tex]a^{(m-n)}[/tex] , then

[tex]\frac{a^{15} }{a^{5} }[/tex]

= [tex]a^{(15-5)}[/tex]

= [tex]a^{10}[/tex]

y + y + (3y - 8) =

= y + y + 3y - 8 = 5y - 8 ← the end

Step-by-step explanation: y+y+3y-8= 5y-8

Answer:

3(x+6)

Step-by-step explanation:

Parenthesis after a number typically means multiply, so 3 times the sum of an unspecified number (x), plus 6 would be 3 (x+6)

Answer:

[tex]x=7[/tex]

Step-by-step explanation:

Hi there!

[tex]-2^2(-5x+10)=100[/tex]

Solve -2^2:

[tex]-4(-5x+10)=100[/tex]

Divide both sides by -4:

[tex]\displaystyle \frac{ -4(-5x+10)}{-4}=\frac{100}{-4} \\\\-5x+10=-25[/tex]

Subtract 10 from both sides:

[tex]-5x+10-10=-25-10\\-5x=-35[/tex]

Divide both sides by -5:

[tex]\displaystyle \frac{-5x}{-5} = \frac{-35}{-5} \\\\x=7[/tex]

Therefore, x = 7.

I hope this helps!

Answer:

Unicorn A is 300 years old

Unicorn B is 20 years old

Explanation:

15x + x = 320

16x = 320

x = 20

15 * 20 + 20 = 320

We have that Each unicorn is 20 ans 300 years receptively

[tex]A=300\\\\B=20[/tex]

From the Question we are told that

UNICORN A IS 15 TIMES OLDER THAN  UNICORN B.

THE SUM OF THEIR AGES  IS 320 YEARS.

Let

x=age of unicorn A

y=age of unicorn B

Therefore

[tex]x=15y....1\\\\\x+y=320.....2[/tex]

Sub (1) into 2

[tex](15y)+y=320\\\\y=20[/tex]

therefore

[tex]x=15(20)\\\\x=300[/tex]

In conclusion

Each unicorn is 20 ans 300 years receptively

[tex]A=300\\\\B=20[/tex]

Answer:

-2 to 2

Step-by-step explanation:

see there's the sign of absolute value around x

so even if we put a negative number in place of x we'll get a positive outcome.

for example,

|x| = 4

|x| = 3

and so on

so the actual domain of |x| reduces to => 0 to 4.

as you'll get the values of |x| in between 0 and 4 throughout -4 to 4.

where the smallest value is 0 and largest is 4.

for range,

I'll just put these smallest and largest values in place of x and solve for domain

y= |0| - 2

y = -2

y = |4| - 2

y= 4 - 2

y = 2

so, the range of the function becomes -2 to 2.

We must create a number line and draw an arrow for each term of the sum.

The procedure is now described:

1) Create a number line with big marks for each unit and small marks for each tenth.

2) Draw an arrow from 0 to 4.2. (Blue arrow in the figure)

3) Create an arrow from 4.2 to 3.8. (Green arrow in the figure)

[tex]x = 4.2 + (-0.4)[/tex]

Answer:

w = 8000

Step-by-step explanation:

5(w+4*10^3) = 6(10^4)

5(w+4*1000) = 6(10000)

5(w+4000) = 60000

5w + 20000 = 60000

5w = 40000

Answer:

Range = 5

Mode = 7

Step-by-step explanation:

To find range we first need to find the highest number and the lowest number

3 , 4 , 4 , 7 , 7 ,7 ,7 7, 8

least number = 3

highest number = 8

now substract the lowest number from the highest to get the range

= 8-3

= 5

range = 5

Mode : the most common number in the list will be our mode

7 is our mode as it came 5 time in the list
