Find The Equation Of The Line That Passes Through (-1,2) And Is Perpendicular To 2y = 2x 1.Leave Your
Answer 2

The equation of line that passes through point (-1,2) and which is perpendicular to 2y = 2x – 1 will be y = -x + 1.

Equation of line

The General equation of a line is ax + by + c = 0

How to solve this problem? Since the line is perpendicular to 2y=2x-1, this means that its slope with be the opposite reciprocal of the line 2y=2x-1 ‘s slope.First, we should find the slope of the line 2y=2x-1:

2y=2x-1

y=x-1/2

Therefore, the slope of 2y=2x-1 is 1 and the opposite reciprocal of 1 is -1 So far, we have this: y=-x+bTo find b (the y-intercept) we can plug the point (-1,2) into the equation we have so far and solve for b.

y=-x+b

2=-(-1)+b

2=1+b

b=1

So, the equation of the line that passes through (-1,2) and which is perpendicular to 2y=2x-1 is y=-x+b

Answers

3 isn’t in the range. Not in the range means it doesn’t have a y value. At y=3, there’s an open dot which means that point doesn’t exist there. At all the other points (0, 4, 5), they have a y value

3 is not in the range.

What is the range?

A function's range is the whole set of potential values that it can have. When we insert an x value into the function, the range is the collection of values that results. Range refers to the y values.

Given a figure in which the function is not differentiable since the graph is broken at  (-2, 3) and (2, 4). Since at Y = 3 there is no point in the graph. therefore Y = 3 is not in the range of the function.

During batting practice, Lenora hit 60% of the 20 pitches that were thrown to her. What fraction of the pitches thrown did Lenora hit?

Answers

Answer:

A 3/5

Step-by-step explanation:Here’s one way to solve this problem.

Write sixty percent as a fraction having a denominator of one hundred.

Now, change sixty-hundredths to an equivalent fraction having a denominator of twenty, the total number of pitches.

Do this by dividing the numerator and the denominator by five.

Then, simplify the fraction twelve-twentieths by dividing the numerator and the denominator by four.

So, Lenora hit three-fifths of the pitches.

Answer:

AB = 17 m, AC ≈ 19.2 m

Step-by-step explanation:

Drawing a line from A to the base creates a right triangle

with legs 8 and (25 - 10 ) = 15

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² = 15² + 8² = 225 + 64 = 289 ( take the square root of both sides )

AB = [tex]\sqrt{289}[/tex] = 17 m

------------------------------------

Using Pythagoras' identity i right triangle ABC

AC² = AB² + BC² = 17² + 9² = 289 + 81 = 370 ( take square root of both sides )

AC = [tex]\sqrt{370}[/tex] ≈ 19.2 m ( to 1 dec. place )

Answers

Answer:

1.30

Step-by-step explanation:

The formula for EP cost is given as:

EP cost = AP cost / yield

From the Question,

AP unit cost = 1.10 per pound

The yield percent = 85%

EP cost = 1.10/85%

EP cost = 1.2941176471

Approximately

The EP unit cost of bell pepper = 1.30

Answer:

Step-by-step explanation:

The travel time is 16:52 -8:13 = 8:39 hours, or 8.65 hours. Then the speed is ...

 speed = distance/time = 527.65 mi/(8.65 h) = 61 mi/h

_____

Additional comment

It is often convenient to use "military" or "24-hour" time for calculations of time periods that extend over noon or midnight. For this purpose, 12 gets added to the hour number in the afternoon (pm). Of course, 39 minutes is 39/60 hours. That is found to be 0.65 hours by performing the division of 39 by 60.
