Just look at the picture lol.....The equations of three lines are given below. Line 1: 8x-6y=-2 3 Line 2: y=-x-5 4 Line 3: 4y=-3x+3 For each pair of lines, determine whether they are parallel, perpendicular, or neither. Line 1 and Line 2: Parallel O Perpendicular O Neither Х Line 1 and Line 3: O Parallel O Perpendicular O Neither Line 2 and Line 3: Parallel O Perpendicular Neither
Answer:
Step-by-step explanation:
We will use the following steps to solve this problem,
Step - (1).
Covert the equations into slope-intercept form.
Step - (2)
If the slopes of the two lines are equal, lines will be parallel.
[tex]m_1=m_2[/tex]
Step - (3)
If the slopes of the two lines are negative reciprocal, lines will be perpendicular.
[tex]m_1\times m_2=-1[/tex]
Line 1: 8x - 6y = -2
6y = 8x +2
y = [tex]\frac{4}{3}x+\frac{1}{3}[/tex]
Slope of line 1 = [tex]m_1=\frac{4}{3}[/tex]
Line 2: y = [tex]-\frac{3}{4}x-5[/tex]
Slope of line 2 = [tex]m_2=-\frac{3}{4}[/tex]
Line 3: 4y = -3x + 3
y = [tex]-\frac{3}{4}x+\frac{3}{4}[/tex]
Slope of line 3 = [tex]m_3=-\frac{3}{4}[/tex]
1). Since, [tex]m_1\times m_2=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]
Line 1 and line 2 are perpendicular.
2). Since, [tex]m_1\times m_3=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]
Line 1 and line 2 are perpendicular.
3). Since, [tex]m_2=m_3=-\frac{3}{4}[/tex]
Line 2 and line 3 are parallel.
A survey of Mr. Thorne’s class shows that 5 out of 8 students will buy lunch today. Based on this result, how many of the 720 students in the school will buy today?
Number of student lunch today is 450 students
Given:
Fraction of student lunch today = 5/8
Total number student = 720 students
Find:
Number of student lunch today
Computation:
Number of student lunch today = Fraction of student lunch today × Total number student
Number of student lunch today = (5/8) × (720)
Number of student lunch today = (5) × (90)
Number of student lunch today = 450 students

Instructions: Find the measure of the indicated angle to the nearest degree.
Answer:
23
Step-by-step explanation:
m∠A=cos⁻¹(35/38) = 22.91954215
round your answer to the nearest tenth.
23 degrees is the measure of the indicated angle in the triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given triangle is a right angled triangle.
The side lengths of triangle are 35 and 38.
We have to find the measure of the angle opposite to the right angle.
By using cosine function formula we calculate it.
CosA=Adjacent side/Hypotenuse
CosA=35/38
m∠A=cos⁻¹(35/38)
= 22.91954215
Hence, 23 degrees is the measure of the indicated angle.

Cheryl fenced in a rectangular kennel and used more fence to divide it into six equally sized sections for her dog i
h is friends as shown. The length of each section is 2 feet more than 3 times its width.
T
If the total amount of fence used for the kennel is 113 feet, what is the area of each section?
Enter the value of the answer in the first blank and enter the units in the second.
Enter your answer in decimal form. Round to the nearest tenth if rounding is necessary.
Enter units as ft., square ft., or cubic ft.
Answer:
The area of each section of the kennel is 33 square ft
Step-by-step explanation:
The given parameters for the fencing are;
The length of each section, L = 2 ft + The width, 3×W
The total amount of fencing = 113 feet
The The total perimeter of the kennel = 12·W + 7·L = 113
Were we are given L = 2 + 3·W
By substitution, we have;
12 × W + 7 × (2 + 3·W) = 113
33·W + 14 = 113
33·W = 113 - 14 = 99
W = 99/33 = 3
W = 3 ft.
L = 2 + 3·W = 2 + 3 × 3 = 11
L = 11 ft.
The area of each section of the kennel, A = L × W = 3 × 11 = 33 square ft.
The area of each section of the kennel = 33 square ft.

3) The International Space Station takes 644 minutes to orbit Earth 7 times. About how long does each orbit take? I got 92 am I correct to crazy? 100 minutes 95 minutes 90 minutes 80 minutes
Given:
The International Space Station takes 644 minutes to orbit Earth 7 times.
To find:
The time taken by each orbit.
Solution:
Total time = 644 minutes
Total number of orbits =7
Now,
[tex]\text{Time taken be each orbit}=\dfrac{\text{Total time}}{\text{Number of orbits}}[/tex]
[tex]\text{Time taken be each orbit}=\dfrac{644}{7}[/tex]
[tex]\text{Time taken be each orbit}=92[/tex]
So, the required time is 92 minutes.
Therefore, you are correct and all options are incorrect.
Which equation represents a line which is parallel to the line 3x + 8y = - 40 ?
Step-by-step explanation:
3x + 8y = -40
8y = -40 - 3x
y = -5 - 3/8x
y = -3/8x - 5
Equation that represents a line which is parallel to y = -3/8x - 5 can be any equation as long as it's y = -3/8x + c, as in c can be any value as long as the other parts of the equation is not changed

Joe is working at the storage yard. It is 50 yards from the entrance (V) to the checkpoint (W). From there, it is 40 yards to the guard post (X). From his spot at the guard post, Joe notices a barrel tipped over 12 yards away (Z). The spill stretches to the fence (Y). If AXYZ is similar to AXVW, what is the distance d across the chemical spill? * zd Y 12 yd X 40 yd 50 yd W
Answer:
15 yds
Step-by-step explanation:
40 divided by 50 equals 4/5, so the lengths of the other triangle have to match that ratio. 3 fits into 12 four times and 15 five times, which makes it a four to five ratio.
