Answer:

a) Parallel when a = -2/3

b) Perpendicular when a = 6

Explanation:

a)  For two parallel lines slopes are equal.

  So, 6y=−2x+4 and 2y=ax−5 parallel if they are slopes equal.

  Slope of 6y=−2x+4, comparing with y = mx + c

     So, m = -2/6 = =-1/3

  For 6y=−2x+4 and 2y=ax−5 to b parallel we have slope of 2y=ax−5 equal to -1/3

   Slope of 2y=ax−5

           m = a/2

    We have a/2 = -1/3

                    a = -2/3

b) For perpendicular lines product of slope is -1.

   So we have

               [tex]\frac{a}{2} *\frac{-1}{3} =-1\\ \\ a=6[/tex]    

The value of 'a' that would make the graphs of the equations 6y = -2x + 4 and 2y = ax - 5 parallel is -1/3. Meanwhile, the value of 'a' that would make them perpendicular is 3.

The question you've asked is about finding the values of a for which two graphs represented by the equations 6y = -2x + 4 and 2y = ax - 5 are either parallel or perpendicular. To solve this, we need to understand and apply the concept of slope in straight-line equations.

Firstly, rewrite the given equations in the form of y = mx + b, where m is the slope. For the first equation, it becomes y = -1/3x + 2/3, so the slope is -1/3.

Parallel lines have the same slope. Therefore, the value of 'a' for the second equation to be parallel with the first needs to be -1/3. Conversely, perpendicular lines have slopes that multiply to -1. Thus, for the second line to be perpendicular to the first, 'a' would have to be the negative reciprocal of -1/3, which is 3.

well, 7+5=12, so he has 5 pencils, then you add 3, which gives you 15. So

Don has 15 markers

Answer:

Don have 15 markers.

Step-by-step explanation:

Don has 5 more pencils than crayons.

Let the number of crayons Don has = 7

number of pencils he has = 5 + 7 = 12

Don has 3 more markers than pencils.

Number of markers Don has = 3 + 12 = 15 markers

Don have 15 markers.

The number 44 is 11 percentage of the number 400, and the correct option is B) 44 = 0.11 * x ; 400

Given data:

The first number is represented as p.

The value of p = 44

The second number is represented as q.

The value of q = q

So, the percentage of the number is A = 11 %, where A = ( p/q ) * 100

On simplifying the equation:

11 = ( 44/q) * 100

q = 4 * 100

q = 400

Hence, the number is 400.

answer: 20

work:

okay, so to solve this, set up as a system of equations and solve:

[tex]\frac{3}{5} = \frac{12}{x}[/tex]

this equation models our problem, because it shows the 3 to 5 ratio and out 12 to x, the number we're trying to find.

so, to solve, cross multiply

3(x) = 5(12)

3x = 20

x = 20

so, when there are 12 oranges, there are 20 pics total.

checking the answer:

the original equation states that "Three out of every five picks are orange" so, this means we can represent this as a fraction, 3/5.

to verify if our other fraction, which we can model as 12/20 is correct, we can simplify it, and if it's equivalent to 3/5 we know it's correct.

so, to simplify we need to find the greatest common factor between 12 and 20 so we can divide both numbers by this fraction.

well, the greatest common factor between these two numbers is 4, so divide both of them by 4.

[tex]\frac{12}{20}[/tex] ÷ [tex]\frac{4}{4} = \frac{3}{5}[/tex]

so, this verifies my answer is correct. hope this helps, and have an amazing day!

In order to find the shaded region the first thing you have to do is find the area of the two small triangles, then find the area of the big triangle. Subtract the area of the small triangles from the big one and that is the area.

Step one: 11×12=132

Step two: 132÷2= 66

Step three: 66+66=132 (because there is two small triangles with same dimensions)

Step four: 40×15=300

Step five: 300-132=168

Answer 168m^2

Answer: 3 m/s

Step-by-step explanation:

1) the instantaneous speed is the slop at t = 6 secs

2) since its a straight line, the slop of the line is the speed and its constant.

the slope is approximately 3 m/s.

3 feet is equivalent to 36 inches. So it starts as a 36-inch diameter.

Then it need to hang down another 5 inches. 36 + 5 = 41. Then he will need another inch to sew down all the way around so that becomes 41 + 1 = 42. 42 inches in diameter.

The table cloth needs to be 42 inches in diameter.

To find Roy's total frequent flyer miles, add his current miles (10,368), the miles he'll earn from his trip to New York (2,832) and the miles he'll earn from his credit card spending (2 miles per dollar spent). The final expression for total miles is 13,200 + 2d where 'd' is the amount spent using the credit card.

Roy's total frequent flyer miles can be calculated by adding his existing miles, his incoming miles from his trip to New York, and the miles gained from using his credit card. Let's assume he spends 'd' dollars using his credit card.

Firstly, we combine the miles he already has and those he will earn from his round trip: 10,368 miles + 2,832 miles = 13,200 miles.

Secondly, we consider his credit card earnings. As he gains 2 miles per dollar spent, he will earn '2d' miles from his credit card spendings.

Finally, we add these together to get the total frequent flyer miles he will have: 13,200 miles + 2d miles. Therefore, the total miles that Roy will have depends on the amount 'd' he spends on his credit card.

The answer would be C since 3.00 would be the initial cost and 5 would be the hourly rate, with x being the amount of hours the car is in the parking lot.

The answer is C. In this situation, slope means the rate of change of the cost of parking in the lot is 5 dollar per hour.

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line. That means the change in y due to change in x.

In an equation, y = mx + c, slope is m.
