A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at
least $20. Solve an inequality that represents how much more you must spend to use the $5
coupon.
(1 Point)
Answer: The answer is m= ≥4.50
The required inequality is m ≥ 4.50
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at least $20.
Cost of the shirt = $15.50
you can use a $5 discount coupon if you spend at least $20
The question requires you to find how much more you need to spend to be able to use the $5 discount coupon
The shirt already cost $15.50
Total amount you need to spend = $20
Let the amount remaining = m
m ≥ $20 - 15.50
m ≥ $4.50
Hence, you need to spend $4.50 in order to be able to use the $5 discount coupon.

B. 12x2 - 3x + 5
C. 6x2 - 3x + 9

The above expression is not in its simplest form, and we need to simplify it, that is what asked in the question.
Given equation,
[tex](9 {x}^{2} - 3x + 7) + ( - 3 {x}^{2} + 2)[/tex]
First of all, let's open the parentheses to combine the like terms for simplifying.
[tex]9 {x}^{2} - 3x + 7 - 3 {x}^{2} + 2[/tex]
Arranging the like terms, x² with x², x with x and constant terms near to each other.

HELP ME PLEASE!! Find R and theta with the coordinates (-3,7).
Answer:
Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.

You ask a friend to think of a number from 7 to 14. What is the probability that his number will be an even number? Answer as a fraction in simplest form.
Answer:
1/2
Step-by-step explanation:
Not sure but
I am assuming we have 8 integers :
All or (A) = {7,8,9,10,11,12,13,14} = n(A) = 8
Hence, the probability of any one outcome is 1/8.
Therefore, as you can detect, there are 4 numbers that are even numbers which means :
Even or (E) = {8, 10, 12, 14} = n(E) = 4
So, let E imply this occurrence
E x A
= 4 x 1/8
= 4/8
= 1/2
Probability of getting an even number from7 to 14 is equals to ( 1/ 2).
What is probability?
" Probability is defined as the mathematical calculation to represents the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
[tex]Probability = \frac{Number of favourable outcome }{Total number of outcomes}[/tex]
According to the question,
Given,
Total number from 7 to 14 = { 7, 8, 9, 10, 11, 12, 13, 14}
⇒Total number of outcomes = 8
Possible outcomes of even number ={ 8, 10, 12, 14}
⇒ Number of favourable outcomes = 4
Substitute the value in the formula we get,
Probability = ( 4 / 8)
= ( 1 / 2) ( fraction in simplest form)
Hence, probability of getting an even number from7 to 14 is equals to ( 1/ 2).

What are the solutions of the equation x4 – 5x2 – 36 = 0? Use factoring to solve. x = ±2 and x = ±3 x = ±2i and x = ±3 x = ±2 and x = ±3i x = ±2i and x = ±3i
Answer:
[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]
Step-by-step explanation:
So we have the equation:
[tex]x^4-5x^2-36=0[/tex]
Let's let u equal x² so:
[tex]u^2-5u-36=0[/tex]
Factor. We can use -9 and 4. So:
[tex]u^2+4u-9u-36=0[/tex]
From the first two terms, factor out a u.
From the last two terms, factor out a -9. So:
[tex]u(u+4)-9(u+4)=0[/tex]
Grouping:
[tex](u-9)(u+4)=0[/tex]
Zero Product Property:
[tex]u-9=0 \text{ or } u+4=0[/tex]
On the left, add 9. On the right, subtract 4:
[tex]u=9\text{ or } u=-4[/tex]
Substitute back u:
[tex]x^2=9\text{ or } x^2=-4[/tex]
Take the square root:
[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]
And we're done!
