Consider two lines having the following equation:
12y-6x=12 line 1
8y+4x=16 line 2
Answer:
x = 1 and y = 1.5
Step-by-step explanation:
Given that,
12y-6x=12 ..... 1
8y+4x=16 ...... 2
Equation (1) can be written as :
2y-x = 2 ... (3)
Equation (2) can be written as :
2y + x = 4 .... (4)
Adding equation (3) and (4)
2y-x + 2y + x = 2 + 4
4y = 6
y = 1.5
Put y = 1.5 in equation (3).
2(1.5)-x = 2
3-x=2
x =1
Hence, the solution of the above equations are (1,1.5).

1/2 servings are in a box of oatmeal that contains6 3/4 cups of oatmeal.
Answer: B) 13 & 1/2
========================================================
Explanation:
There are a few ways to approach this problem. It might be easiest to convert all the fractions to decimal form
1/2 = 0.5
3/4 = 0.75
6 & 3/4 = 6 + 3/4 = 6 + 0.75 = 6.75
The problem is rephrased as: "How many 0.5 cup servings in a box of oatmeal that contains 6.75 cups of oatmeal?"
To find out, we divide the two values (large over small) to get 6.75/0.5 = 13.5
Then convert back to a mixed number:
13.5 = 13 + 0.5 = 13 + 1/2 = 13 & 1/2
--------------------
Side note: The reason why we divide is due to this
x = number of servings
0.5x = total number of cups = 6.75
So we're effectively solving the equation 0.5x = 6.75, in which we divide both sides by 0.5

Which Sentence about measuring angles is true?
A. An angle that turns through 10/360 of a circle has a measure of 36°
B. An angle that through 1/12 of a circle has a measure of 1°.
C. An Angle that turns through 10/360 Of a circle has a measure 10°
D. An angle that turns through 1/12 Of a circle has a measure of 12°
Pls help I have to stay up all night answering 200 Questions
The statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.
Angle
When two straight lines or rays intersect at a shared terminal, an angle is generated. The angle can be measured in degrees or radians.
How to find a true statement about measuring the angle from the given statements?Let us discuss all four options.
The measure of a whole circle is [tex]360^{o}[/tex]
(A) Here, [tex]\frac{10}{360}\times360=10^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]36^{o}[/tex]" is false.
(B) Here, [tex]\frac{1}{12}\times360=30^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{1}{12}[/tex] of a circle has a measure of [tex]1^{o}[/tex]" is false.
(C) Here, [tex]\frac{10}{360}\times360=10^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.
(D) Here, [tex]\frac{1}{12}\times360=30^{o}[/tex]
That is, the statement "An angle that turns through [tex]\frac{1}{12}[/tex] of a circle has a measure of [tex]12^{o}[/tex]" is false.
Therefore, option (C) is correct.
Hence, the statement "An angle that turns through [tex]\frac{10}{360}[/tex] of a circle has a measure of [tex]10^{o}[/tex]" is true.

Given |u| = 10 at ∠135° and |v| = 5 at ∠30°, what expression can be used to find |u + v|?
(10)2 + (5)2 – 2(10)(5) cos(45°)
(10)2 + (5)2 – 2(10)(5) cos(75°)
(10)2 + (5)2 – 2(10)(5) cos(105°)
(10)2 + (5)2 – 2(10)(5) cos(165°)
Answer:
B, [tex]10^{2} + 5^{2}- 2(10)(5)cos(75)[/tex]
Step-by-step explanation:
Using the law of cosines, which is [tex]c^{2}=a^{2}+b^{2}-2ab cos(C)[/tex], you can simply insert all the values.
c=|u+v|
a= r value of u (10)
b= r value of v (5)
To find C, you simply have to subtract v from u, and then subtract that number from 180 to find the reference angle.
I.E.: ∠135 - ∠30 = ∠105 ↔ 180 - 105 = 75 = C
so, the completed equation would be 10^{2} + 5^{2}- 2(10)(5)cos(75)

Conclusion:
-a-1 will be positive.Step-by-step explanation:
Checking -a - 1
From the given line number, we can determine that
The value of a will be negative because it is located on the left side of the origin 0.
i.e. value of a > -2
so
-a - 1 will be positive because if we put the value a = -1.5 let say
then
-a - 1 = -(-1.5) - 1 = 1.5 -1 = 0.5
Therefore, -a-1 will be positive.
Checking -b + 2
As b > 2
putting b = 2.1 (taking the value of b slighly above than 2)
-b+2 = -2.1+2 = -0.1
Therefore, -b + 2 will be negative.
Conclusion:
-a-1 will be positive.which linear equation has a slope of 1/2 and a y-intercept at (0,0)

Question 12 The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of and a standard deviation of . Find the probability that the mean GPA of a random sample of students selected from this university is or higher.
Complete question :
The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and a standard deviation of .29.Find the probability that the mean GPA of a random sample of 20 students selected from this university is 3.10 or higher.
Answer:
0.10868
Step-by-step explanation:
Given that :
Mean (m) = 3.02
Standard deviation (s) = 0.29
Sample size (n) = 20
Probability of 3.10 GPA or higher
P(x ≥ 3.10)
Applying the relation to obtain the standardized score (Z) :
Z = (x - m) / s /√n
Z = (3.10 - 3.02) / 0.29 / √20
Z = 0.08 / 0.0648459
Z = 1.2336940
p(Z ≥ 1.2336) = 0.10868 ( Z probability calculator)
Find any points of discontinuity for y = 5x+6/x2+6x+9
Answer:
x = -3 is the point of discontinuity.
Hence, option B is correct.
Step-by-step explanation:
Given the expression
[tex]y=\frac{5x+6}{x^2+6x+9}[/tex]
In order to determine the discontinuity, the denominator must be 0.
so let us solve the denominator to get the values of x
[tex]x^2+9x+9\:=0[/tex]
[tex]\left(x+3\right)^2=0[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]x+3=0[/tex]
Subtract 3 from both sides
[tex]x+3-3=0-3[/tex]
[tex]x = -3[/tex]
Therefore, x = -3 is the point of discontinuity.
Hence, option B is correct.

[tex]\tt Step-by-step~explanation:[/tex]
Since the sum of the interior angles of a triangle is always 180º, we know that ∠CED and ∠ECD are less than 87º altogether. This is because 93º + 87º = 180º. 87º is already less than 90º, so we know that ∠CDE is the largest angle of this triangle.
