Answer:
x = 2
Step-by-step explanation:
Using the rule of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
[tex](2)^{3x}[/tex] = [tex]2^{3x}[/tex] and 8 = (2³ )² = [tex]2^{6}[/tex] , so
[tex]2^{3x}[/tex] = [tex]2^{6}[/tex]
Since the bases on both sides are equal, both 2, equate the exponents
3x = 6 ( divide both sides by 3 )
x = 2
10x - 12y = 22
5x - 6y = 11 elimanation
Answer:
This is an identity or infinite solutions
Step-by-step explanation:
10x - 12y = 22
5x - 6y = 11
-2(5x - 6y = 11 )
-10x + 12y = -22
10x - 12y = 22
0=0
Identity solution
Answer:
2(5x - 6y = 11)= 10x - 12y = 22 so they are the same equation

Xander is starting his own small business. He borrows $10,000 from the bank at a 4% rate for 5 years. Find the interest he will pay on this loan.
Answer:
$6000
Step-by-step explanation:
Given data
Principal=$10000
Rate=4%
time=15years
The simple interest id found by
SI=PRT/100
substitute
SI=10000*4*15/100
SI= 600000/100
SI=$6000
Hence the interest is $6000
Which expression is the factorization of x^2+10x+21?
Answer:
To factor a trinomial in the form Ax^2 + Bx + C when the A = 1. You need to find the factors of C that when added or subtracted will give you B.
Factors of 21 are either 1,21 or 3,7. Since +3 and +7 will give you 10 then those will be the two factors you will use.
Factoring x^2+10x+21 will give you (x+3)(x+7)
Step-by-step explanation:
Answer:
(x+3)(x+7)

-4x+y=23 and 4x-9y=-15
Answer: x= -6; y= -1
Step-by-step explanation:
-4x + y = 23
4x - 9y = - 15
-4x + y = 23
y = 23 + 4x [Add 4x to both side]
4x - 9(23 + 4x) = - 15
4x - 207 - 36x = - 15
-32x - 207 = -15
-32x = 192 [Add 207 to both side]
x = -6 [Divide -32 from both side]
-4x + y = 23
-4(-6) + y = 23 [Plug in -6 for x]
24 + y = 23 [Subtract 24 from both side]
y = -1
Which of the following are written in point-slope
form?
a) y = 4x + 6
b) y + 3 = -2(x – 6)
c) x + y = 10
d)y- 1 = 5(x + 7)
Melissa has an outstanding credit card balance of $2200. Interest is charged at a rate of %15 p.A. The amount that Melissa must pay off the card is how much?
Answer:

It takes a new mail carrier 4 hours to deliver the mail on route a. It takes an experienced mail carrier 3 hours to do the same job. How long would it take if they worked together?
Answer: [tex]\frac{12}{7}\ \text{hours}[/tex]
Step-by-step explanation:
Given
New mail carrier takes 4 hours for delivery i.e.
New mail carrier completes [tex]\frac{1}{4}[/tex] part of work in 1 hour
Old mail carrier takes 3 hours for delivery i.e.
mail carrier completes [tex]\frac{1}{3}[/tex] part of work in 1 hour
If they work together, they complete the work in x hours i.e.
[tex]\Rightarrow \dfrac{1}{x}=\dfrac{1}{4}+\dfrac{1}{3}\\\Rightarrow \dfrac{1}{x}=\dfrac{3+4}{12}\\\Rightarrow x=\dfrac{12}{7}\ \text{hours}[/tex]

Which set of values makes the inequality n > -5 true?
A
{-5, -5.5, -6}
B
{-5, -4.5, -3}
С
{-6,0,5}
D
{-6, -7,-8}
Answer:
B
Step-by-step explanation:
≥ means that it is greater than or equal to.
Any set that has all numbers over or equal to -5 would be correct, meaning that -5, -4.5, and -3 would be correct.
Hope this helps. Have a nice day.
Inequalities help us to compare two unequal expressions. The set of values makes the inequality n > -5 true is {-5, -4.5, -3}.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
As we need to find the values that will satisfy the inequality n≥-5, therefore, we need values that are greater than or equal to -5.
Hence, the set of values makes the inequality n > -5 true is {-5, -4.5, -3}.

Pythagorean theorem: [tex]a^{2}+b^{2}=c^{2}[/tex]
Answer:
B
Step-by-step explanation:
Pythagorean theorem states that a²+b²=c²
Through observation, I assumed that 8 was the hypotenuse
I sqaured both the known lengths of the leg and hypotenuse and plugged them into the equation: a²+36=64
I subtracted 36 from 64 leaving me with 28=a²
Then in order to isolate the variable I had to apply square root to both values, cancelling the "²" and leaving me with √28=a
