What is the y-intercept of the equation of the line that is perpendicular to the line y = x + 10 and passes through the point (15, –5)?
The equation of the line in slope-intercept form is y = x +
Answers
perpendicular lines, slope is opposite and reciprocal
so perpendicular line slope = -1
passes through the point (15, –5)
y = mx + b
-5 = -1(15) + b
b = -5 + 15
b = 10

The coordinates of the mid - point are - M(2, 2.5).
We have two coordinate points - A(2, 1) and B(2, 4)
We have to find the midpoint of this line AB.
What is Mid - Point Theorem?It states that a line with endpoint coordinates as - [x(1), y(1)] and [x(2), y(2)] has its mid - point at the coordinates -
x(m) = [tex]$\frac{x(1)+x(2)}{2}[/tex]
y(m) = [tex]$\frac{y(1) + y(2)}{2}[/tex]
According to question, we have -
First coordinate Point - A(2, 1)
Second coordinate Point - B(2, 4)
Using the Mid - Point formula, we get -
x(m) = [tex]$\frac{x(1)+x(2)}{2} = \frac{2+2}{2} =2[/tex]
y(m) = [tex]$\frac{1+ 4}{2}=2.5[/tex]
hence, the coordinates of the mid - point are - M(2, 2.5).

Ashely walks 2 1/2 miles around a lake around three times a week. If Ashley walks around the lake in 3/4 hour,what is her rate of speed? (Hint: Use the formula r= d/t, where the r is rate, d is distance, and t is time.
Answers
Rate = Distance/Time.
First, you should fill in what you know. In this case, you know the distance is 2.5 miles, and the time is 0.75 hours. Now, you simply plug in the known variables to the formula to get Rate = 2.5 miles / 0.75 hours. After dividing, you reach the answer Rate = 3.333333 (or 3 and 1/3) miles/hour.

What is 0.21212121.... as a fraction
Answers
if 2 numbers repeat, it's probbalby divided by 99
like 0.abababababab=ab/99
so
0.21212121
21 repeats
so it is 21/99 or 7/33
0.21212121.... = x
multiply each side by 100
21.212121.... = 100x
remember that x is 0.21212121? we can subtract that now from 21.21212121, as well as x from 100.
21.212121... - 0.212121... = 100x - x
we are left with 21 = 99x
21 = 99x
simplify....
7 = 33x
and divide!
7/33 = x
Your answer is: 0.2121212121.... = 7/33

Jesse and three friends buy snacks for a hike. They buy trail mix for $5.42, apples for $2.55, and granola bars for $3.99. If the four friends split up the cost of the snacks equally, how much should each friend pay?
Answers
2.99 because you add the total cost up, which would be 11.96. So then you would divide 11.96 by 2.99 which gives you 2.99

The complete pattern is 47, 57, 66, 74, 81, 87, 92, 96, 99, 101, 102.
What is pattern of numbers?A recurring arrangement of numbers, forms, colours, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.
The given sequence of numbers are 47, 57, 66, 74, 81, 87, 92.
Here, 47+10=57
57+9=66
66+8=74
74+7=81
81+6=87
87+5=92
92+4=96
96+3=99
99+2=101
101+1=102
So, the next 4 terms of the given pattern are 96, 99, 101, 102
Therefore, the complete pattern is 47, 57, 66, 74, 81, 87, 92, 96, 99, 101, 102.

1. Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. Happy Hounds charges a flat fee of $21 plus $1 per hour. For how many hours is the total fee charged by the companies the same?
Answers
peppy pets 15 + 3x
happy hounds 21 + x
15 + 3x = 21 + x
subtract x from both sides
15 + 2x = 21
subtract 15 from both sides
2x = 6
divide each side by 2
x = 3 hours
Algebraic equations are equations that consist of unknown variables. These variables can be represented using the letters of the alphabet.
The total fee charged by the companies will be the same in 3 hours.
Let's represent the number of hours as :h
Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. The algebraic equation to represent this statement is given as:$15 + $3 x h
15 + 3h ..........Equation 1
Happy Hounds charges a flat fee of $21 plus $1 per hour. The algebraic equation to represent this statement is given as:$21 + $1 x h
21 + h ..........Equation 1
We equate both equations to each other
Equation 1 = Equation 2
15 + 3h = 21 + h
Collect like terms
3h - h = 21 - 15
2h = 6
Divide both sides by 2
2h/2 = 6/2
h = 3
Therefore, the total fee charged by the companies will be the same in 3 hours.

3. The equation below represents how many hours, x, it will take to travel 210 miles at an average speed of 60 miles per hour.
How long will it take? 60x210
Answers
Final answer:
To solve the given problems, use linear equations: for cupcakes, 4x = 36; for Sam's age, x = 15 - 3; and for travel time, 210 = 60x.
Explanation:
1. To find how many cupcakes, x, can be purchased for $36.00 when each cupcake costs $4.00, we use the equation 4x = 36. This equation represents the cost of cupcakes multiplied by the number of cupcakes equals the total cost.
2. For determining Sam's age, given that Sam is 3 years younger than Marco, who is 15 years old, we represent Sam's age with x. The equation to calculate Sam's age would be x = 15 - 3.
3. The equation presented as 60x210 seems to be a mistake. To find out how many hours, x, it will take to travel 210 miles at an average speed of 60 miles per hour, the correct equation is 210 = 60x.
