Answers
Answer:
y = 6
Step-by-step explanation:
[] We can plug in our x value of -3, from the coordinate point, and solve for y.
y = 3 - x
y = 3 - (-3)
y = 3 + 3
y = 6
[] We can also graph the equation, and find the point where x = -3

Answer:
Hello, the correct answer is, 27
Step-by-step explanation:
Substitute -3 into -x
We know that since they are both negatives, they cancel out. Therefore, you substitute 3 into y = 3^-x.
y = 3^3
y = 27

Which values from the set {-6, -4, -3, -1, 0, 2} satisfy this inequality? 1/2x+3>5
Answers
Answer:
-12x+3 greater than or equal to 5
-12x greater than or equal to to 2
To turn the negative sign of -12x into positive, we multiply both sides by minus, which shifts the inequality sign.
So, 12x less than or equal to 2
x is less than or equal to 1/6
Therefore, 0, -1, -3, -4 and -6 satisfy this inequality

Ms. reed makes salad dressing by combining oil and vinegar. she combines 8 fluid ounces of oil and 3 fluid ounces of vinegar to make one batch. Ms. Reed makes 3 batch of salad dressing. How many total cups of salad dressing does she makes ?
Answers
By performing a change of units, we will see that she did make 1.375 cups of salad dressing.
How many total cups does she make?First, we know that she combines 8 oz of oil and 3 oz of vinegar, then the total volume in ounces is:
V = 8oz + 3 oz = 11 oz
Now we want to know how many cups there are in 11 ounces, so we need to perform a change of units.
We know that:
1 oz = 0.125 cups
Then we can write:
11 oz = 11*(1 oz) = 11*(0.125 cups) = 1.375 cups

Maurice has completed 72 pages of the research paper he is writing. That is 90% of the required length of the paper. What is the required length of the paper?
Answers
Answer:
its 100 pages ................
Answer:
80
Step-by-step explanation:
When we first look at this, it generally says "90% of what number is 72?" so that's what we can do.
We can change 90% into a decimal, and put in x, which is what our answer will be!
[tex]0.9*x=72[/tex]
We can multiply both sides of this equation by 100, and then divide by 90. After all of this, we have
[tex]x=72*10/9[/tex], which is 80.

There are several ways to prove a mathematical statement. These ways include: by contradiction, by induction, contraposition, etc
How to prove the statement by contradictionTo prove the statement, we make use of proof by contradiction
From the question:
x is a composite number such that: x > 1
This means that 1 < a < x is a factor of x
This can be represented as:
[tex]x = a * b[/tex]
Where:
a and b are positive integers1 < a, b < xAssume that b is less than or equal to a.
Also, let
[tex]b > \sqrt x[/tex]
This means that:
[tex]\sqrt x < b \ge a[/tex]
The above becomes
[tex]\sqrt x < a[/tex]
Rewrite as:
[tex]a > \sqrt x[/tex]
So, we have:
[tex]x = a * b > \sqrt x * \sqrt x = x[/tex]
The above means that:
[tex]x > x[/tex]
The above inequality is a contradiction because, a number x cannot be greater than itself
This means that, the supposition is wrong.
Hence, the given statement has been proved by contradiction

Use Euclid's division algorithm to find the HCF of 135 and 225
Answers
Answer:
The answer is 45
Step-by-step explanation:
135 and 225
Here, 225 > 135
225 = 135 × 1 + 90
Since remainder ≠ 0, we apply division Lemma to 135 and 90
135 = 90 × 1 + 45
Since remainder ≠ 0, we apply division Lemma to 90 and 45
90 = 45 × 2 + 0
Since remainder = 0, divisor 45 is the HCF
Thus, HCF (135, 225) = 45
-TheUnknownScientist 72
Answer:
HCF = 45
Step-by-step explanation:
225 = (135 × p) + q
⇒ 225 = (135×1) + 90
⇒ 135 = (90 × 1) + 45
⇒ 90 = (45 × 2) + 0
HCF (135, 225) = 45
