Please do and explain numbers 2, 4, 6, and 8, thank you.
Answer:
2. w = -3
4. c = -2
6. r = 7
8. n = 4
Step-by-step explanation:
It's hard to read the photo, but I'll try.
2.
[tex] 2^{w + 4} \times 2^{4w + 6} = 2^{2w + 1} [/tex]
On the left side, you have a product of 2 powers with the same base.
Give the same base and add the exponents, as in the rule
[tex] a^m \times a^n = a^{m + n} [/tex]
You get on the left side 2 to the sum of the exponents.
[tex] 2^{w + 4 + 4w + 6} = 2^{2w + 1} [/tex]
Simplify the long exponent on the left side.
[tex] 2^{5w + 10} = 2^{2w + 1} [/tex]
Now we have another rule we can use. If two powers are equal, and their bases are equal, then the exponents must be equal.
Here, 2 to the power 5w + 10 equals 2 to the power 2w + 1. Since both bases are 2 and are equal, then the exponents must be equal.
5w + 10 = 2w + 1
Subtract 2w from both sides. Subtract 10 from both sides.
3w = -9
Divide both sides by 3.
w = -3
4.
[tex] \dfrac{1}{5} = 5^{2c + 3} [/tex]
We need to write the left side as a power of 5. Then we equate the exponents like we did in problem 2.
Recall the rule:
[tex] a^{-n} = \dfrac{1}{n} [/tex]
Apply this rule to the left side in reverse.
[tex] 5^{-1} = 5^{2c + 3} [/tex]
Now we have two powers that are equal, both having the same base, 5, so the exponents must be equal.
2c + 3 = -1
2c = -4
c = -2
6.
[tex] 216 = 6^{2r - 11} [/tex]
This is the same idea as problem 4. Write the left side as a power of 6.
[tex] 6^3 = 6^{2r - 11} [/tex]
[tex] 2r - 11 = 3 [/tex]
[tex] 2r = 14 [/tex]
[tex] r = 7 [/tex]
r = 7
8.
[tex] 4^{n} \times 4^{2n - 9} = 64 [/tex]
This problem is similar to problem 2.
[tex] 4^{n + 2n - 9} = 4^3 [/tex]
[tex] 4^{3n - 9} = 4^3 [/tex]
3n - 9 = 3
3n = 12
n = 4

Step-by-step explanation:
Both angles are equal, so we just formulate the equation and solve for x.
x + 15 = 6x - 65
80 = 5x
16 = x
X = 16

if you are picking a number between 1-20 what is the probability that you will pick an even numder or a multiple of three
Answer:
The probability of an event happening is desired outcome/sample space.
For our sample space, it’s just the number of numbers: 20.
The outcome you want has some overlap: 6. 12. 18. So, we’ll subtract these as they fit both criteria.
Even numbers: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 (10 numbers)
Multiples of 3: 3, 6, 9, 12, 15, 18 (6 numbers)
Pr(A or B) = Pr(A) + Pr(B) - Pr(overlap, also known as A intersect B)
Pr(even or mult. of 3) = 10/20 + 6/20 - 3/20 (the overlap)
= 13/20.
So, there is a 65% of you picking an even number or a multiple of three.

Slove each inequality and graph it’s solution. (the sign has a line under it but I can’t do it on my keyboard)

Please Help me do this
1. Old value = 5
New value = 10
Percent Change = 10 - 5 / 5 × 100%
= 5/5 × 100%
= 100% (increase)
2. Old value = 40
New value = 20
Percent Change = 20 - 40 / 40 × 100%
= -20/40 × 100%
= -1/2 × 100%
= -50% (decrease)
3. Old value = $50
New value = $40
Percent Change = $40 - $50 / $50 × 100%
= -$10/$50 × 100%
= -1/5 × 100%
= -20% (decrease)
Which steps should be used to graph the equation below? y-4=1/3(x+2)
-> First, we want to put it into more of a slope-intercept form so we can graph.
y - 4 = 1/3 (x + 2)
y = 1/3 (x + 2) + 4
y = 1/3x + 2/3 + 4
y = 1/3x + 14/3
-> Next, we will plot the point (0, 14/3) because it is the y-intercept of our equation
-> Last, we will move up one and to the right three, following the pattern of "rise over run" with our slope of 1/3
[] The finished graph is attached
[] I have also graphed the original equation to show that they overlap, showing that our simplification works
Have a nice day!

The store paid $2.70 for a book and sold it for $6.20. What is the profit as a percent?
Answer:
129.6% profit
Step-by-step explanation:
1)Firstly in order to find the overall profit you take away $2.70 from $6.20 = $3.50
2)The next step is to put the profit over the amount paid = 3.50/2.70 = 35/27.
3)In order to find the percentaage you multiply 35/27 by 100 = 129.629 recurring. This rounded to 1 decimal place is 129.6%

===================================================
Explanation:
The ratio 1:5:6 scales up to x:5x:6x for some positive real number x.
The three interior angles are x, 5x and 6x. For any triangle, the interior angles always add to 180.
x+5x+6x = 180
12x = 180
x = 180/12
x = 15
So,
5x = 5*15 = 756x = 6*15 = 90The triangle has angles of 15, 75 and 90 degrees.
Because we have a 90 degree angle, this is a right triangle.
Note how 15+75+90 = 180 to help confirm the answer.

Three years ago, Jolene bought $750 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of 12
1
2
% per year. How much is the stock worth now? (Round each money calculation you make to the nearest cent.)
Answer:
1053.7$
Step-by-step explanation:
750$ x 12%= 90
first year: 750 + 90 = 840
840$ x 12%= 100.8$
second year: 840+ 100.8= 940.8
940.8$ x 12%= 112.896
third year (now)= 940.8+ 112.896 = 1053.696$

.
Answer:
y+what ever the angle inside=180 since its on a line
180-128=52
52+z+x=180since thats always the angles of a triangle added up
52+91+x=180
add
143+x=180
-143
x=37

There are 102 coins with the value of 17.10$ and they are quarters and dimes, how many of the coins are dimes
Answer:
Let x = number of dimes
y = number of quarters
Equation 1 is then x + y = 100, that one is easy.
Now you have to worry about values of each, and since a dime is $0.10 and a quarter is $0.25, that means that the number of each times their respective dollar amounts has to add up to the total dollar amount.
Equation 2 is then 0.1x + 0.25y = 14.05
To rewrite for clarity you have:
x + y = 100 (1)
0.1x + 0.25y = 14.05 (2)
Now you can solve this any number of ways, I'm going to use addition by multiplying both sides of equation 1 by -1/10 and then adding it to equation 2.
-0.1x - 0.1y = -10
0.1x + 0.25y = 14.05
0.15y = 4.05
don't let the decimals trip you up, that's the same as
15y = 405
y = 27 quarters
Now use that value in the original equation 1 to get
x = 100 - 27 = 73 dimes
To check use the values in the equation 2
$0.1*(73) + $0.25*(27) = $14.05
$7.30 + $6.75 = $14.05
