Determine if the linear equations are parallel, perpendicular, or neither.
y = - 2x, 2y = x, 4y = 2x + 4
a
perpendicular
b
neither
c
parallel
Answer:
C. Neither
Step-by-step explanation:
The first equation is
This equation is already in the slope-intercept form;
The slope of this equation is 2.
The second equation is .
This equation is also already in the slope-intercept form.
The slope of this equation is .
Since the two slopes are not the same, the two lines are not parallel.
If these two lines are perpendicular, then the product of their slopes is -1.
But which is not equal to -1.
Therefore the two lines are also not perpendicular.
The correct choice is C.
The ratio of destroyers to battleships in the navy is 20:15. If the total number of boats is 105, how many battleships are there?
Answer:
45
Step-by-step explanation:
20:15 the ratio can be turned to a fraction
20/15
simplify
4/3
so now add the numerator and the denominator and get 7
then do 105/7=15
and then you do
4x15=60 (Destroyers)
3x15=45 (Battleships)
45 is your answer

Two points are graphed on a coordinate grid. Point A is located at (-8, -3) . Point B is created by reflecting point A over an axis. Which coordinates could be the coordinates of point B
The point (-8, -3) is reflected on x-axis, we have (-8, 3) and the point is reflected on y-axis, we have (8, -3). Therefore, options A and E are the correct answers.
What is the reflection on x-axis?When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).
The given coordinate point A is (-8, -3).
Reflection on x-axis, we get
(-8, -3)→(-8, 3)
The reflection of point (x, y) across the y-axis is (-x, y).
Reflection on y-axis, we get
(-8, -3)→(8, -3)
Therefore, options A and E are the correct answers.

Of the seeds Quincey planted in his tomato garden, 75% grew into mature plants. If Quincey has 39 tomato plants in his garden, how many seeds did he plant?
PLEASE HELP WORTH 70 POINTS
Answer:
52 seeds.
Step-by-step explanation:
So, 3/4 of his plants have grown. SO, 3/4 = 39 plants, and if we divide by 3, we get 1/4 of the plants are 13 plants. SO, if we want to find 4/4, we can multiply 13*4=52 seeds.
Quincey planted 52 seeds in total.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
75% grew into mature plants.
If Quincey has 39 tomato plants in his garden.
let x number of seed he planted.
So, 75% of x= 39
75x/100= 39
75x = 3900
x = 52
Hence, He planted 52 seeds.

The length of the lunch area is 6 1/2 times it's width. If the width of the area is 10 6/13 feet, what is the length in simplest form?
Answer:the length of the Lunch area= 68 feet
Step-by-step explanation:
Since width of lunch area is given = 10 6/13 feet
and Length of the lunch area is 6 1/2 times it's width.= 6 1/2 x Width
Length = 6 1/2 x 10 6/13
changing to improper fraction foe easy solving
13/2 x 136/13
13 cancels out 13, we are left with
136/2 =68 feet
