Answer:
1. y= 2/3x + 4, and y = 2/3x - 1 are parallel
2. y = 1/3x - 3 and y = 2x + 5 are perpendicular
3. y =2/5x +4 and y = 0.2x - 1 are intersecting
4. y = -x + 13 and y = x-14 are perpendicular
Step-by-step explanation:
The equation of lines are solved and parallel lines are
a) y = 2/3x + 4 , y = ( 2/3 )x - 1
Perpendicular lines , y = -( 1/2 )x - 3 , y = 2x + 5
Intersecting lines
a) y = ( 2/5 )x + 4 , y = 0.2x - 1
b) y = -x + 13 , y = x - 14
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
y = 2/3x + 4 , y = ( 2/3 )x - 1
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = 2/3
So , the slopes of the two lines are same and they are parallel lines
And , y = -( 1/2 )x - 3 , y = 2x + 5
The slopes are negative reciprocals of each other , so they are perpendicular lines
Now , the intersecting lines are a) y = ( 2/5 )x + 4 , y = 0.2x - 1
b) y = -x + 13 , y = x - 14
Hence , the equation of line is solved

Step-by-step explanation:
distribute 3 to 4x+2 --> 12x + 6 = 8x + 24 - 2x
combind like terms --> 12x + 6 = 6x + 24
subtract 6 from both sides --> 12x +6 -6 = 6x + 24 - 6 --> 12x = 6x + 18
subtract 6x from both sides --> 12x - 6x = 6x -6x +18 --> 6x = 18
divide both sides by 6 to get what x equals --> x = 3
Ben was holding a bake sale to raise money for his field trip. He sold cookies for $2 each, muffins for $1 each, and lemonade for $4 a bottle. If he sold 24 cookies, 13 muffins, and 36 bottles of lemonade, how much money did he raise for his field trip? Explain how you found your answer.
Answers
Answer: he raised $205
Step-by-step explanation:
cookies: $48 (24x2)
muffins: $13 (13x1)
lemonade: 144 (36x4)
144+13+4=$205

At a Christmas party,40 people wore a grinch or elf costume. If there were 50 people at the party and 10 were dressed as the grinch, what percent were wearing an elf costume ?
Answers
Answer:
Percent [wearing elf costume] = 60%
Step-by-step explanation:
Given:
Total number of people = 50
Grinch or elf costume = 40
Grinch costume = 10
Find:
Percent [wearing elf costume]
Computation:
Percent [wearing elf costume] = [Grinch or elf costume - Grinch costume] / Total number of people
Percent [wearing elf costume] = [40-10] / 50
Percent [wearing elf costume] = [30] / 50
Percent [wearing elf costume] = 60%

If a point is originally located at (2,9) and is translated 4 units to the right and 7 units up, what would its new
coordinates be?
Answers
Given:
The point is (2,9).
It is translated 4 units to the right and 7 units up.
To find:
The coordinates of new point.
Solution:
The point is translated 4 units to the right and 7 units up. So, the rule of translation is
[tex](x,y)\to (x+4,y+7)[/tex]
The point is (2,9). Using the above rule, we get
[tex](2,9)\to (2+4,9+7)[/tex]
[tex](2,9)\to (6,16)[/tex]
Therefore, the coordinates of new points are (6,16).

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour. Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour. How many hours until they have the same amount of fruit left?
Answers
Answer:
72.1 hours
Step-by-step explanation:
Let the number of hours be represented as: x
Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.
Convert 2 7/8 pounds to decimal = 2.875pounds
Hence:
252 - 2.875x
Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.
Convert 3 1/3 pounds to decimal = 3.333 pounds
Hence:
285 - 3.333x
How many hours until they have the same amount of fruit left?
This calculated by equating both equation together
252 - 2.875x = 285 - 3.333x
Collect like terms
-2.875x + 3.333x = 285 - 252
0.458x = 33
x = 33 / 0.458
x = 72.052401747 hours
x ≈ 72.1 hours
They would have the same amount of fruit left after 72.1 hours

Olivia is a stockbroker. She makes 4% of her sales in commission. Last week, she sold $7,200 worth of stocks.
a. How much commission did she make last week?
b. If she were to average the same commission each week, how much would she make in commission in a year, treating a year as having exactly 52 weeks.
Answers
Answer:
i think a is 6912:)
i thin b is 359424:)
Step-by-step explanation:
i'm so sorry if it's wrong <3
The answers for the given problem are as (a) the commission made by Olivia in a week is $288 and (b) the total commission for a year is $14976.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
And to convert a fraction or a decimal into percentage, they are multiplied by 100.
Given that,
The price of stocks sold = $7200.
The commission percentage = 4%.
(a) The commission made by Olivia per week is found as,
4% of 7200
= 4/100 × 7200
= 288
(b) Considering 52 weeks in a year, the commission made by her in a week is given as,
52 × 288
= 14976
Hence, the commision made by her in a week is $288 and the total commission for a year is $14976.

[50 pts] An even number, n, times the next consecutive number, n + 2, is equal to 168. Find the original number.
Answers
We are given:
An even number 'n', multiplied by the next consecutive even number is 168
Solving for n:
From the given statement, we can say that:
n(n+2) = 168 [n multiplied by the next even number 'n+2']
n² + 2n = 168
n² + 2n - 168 = 0 [subtracting 168 from both sides]
We can see that we now have a quadratic equation, solving using splitting the middle term
n² + 14n - 12n - 168 = 0
n(n + 14) -12(n + 14) = 0 [factoring out common terms]
(n-12)(n+14) = 0
Here, we can divide both sides by either (n-12) OR (n+14)
Checking the result in both the cases:
(n + 14) = 0/(n-12) (n-12) = 0/(n+14)
n + 14 = 0 n - 12 = 0
n = -14 n = 12
Both these values are even and since we are not told if the number 'n' is positive or negative, both 12 and -14 are the possible values of n

What Is an Isosceles Triangle?A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.
In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle
The three types of Isosceles Triangles are :
Isosceles acute triangle
Isosceles right triangle
Isosceles obtuse triangle
Given data ,
Let the isosceles triangle be represented as ΔABC
In an isosceles right triangle, the two legs are congruent, so if one leg has a length of 3 ft, then the other leg also has a length of 3 ft. Let's call the length of the hypotenuse h.
Using the Pythagorean theorem, we can find the length of the hypotenuse:
h² = 3² + 3²
h² = 18
Taking square roots on both sides , we get
h = 3√2 feet
The perimeter of the triangle is the sum of the lengths of its sides:
Perimeter = 3 + 3 + 3√2 = 6 + 6 + 3√2 feet
Hence , the perimeter is 6 + 3√2 feet
