What is the slope of a line perpendicular?

y=-3/4x +3

Answers

Answer 1
4/3
Remember if two lines are perpendicular, the product of their slopes are -1
Answer 2

Answer:

4/3        equation however is y = 4/3x + 3 (the plus three can be changed to anything

Step-by-step explanation:

Lemme just tell you this:

If you are looking for the equation of a completely perpendicular line,

just find the COMPLETE OPPOSITE of the current slope. -3/4x would be 4/3 because it is the opposite in terms of positive or negativeness and the way the numbers are arranged. Change the sign, flip the number, and you are good to go.

You have 5814 meters of rope you need to cut into 27 sections how many 27 meters secton of rope will you be able to create and how much rope will be left over as waste

Answers

Answer:

215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left

Step-by-step explanation:

we have 5,814 meters of rope and we are told to calculate the number of 27 meters sections that we can cut:

you have to divide 5,814 meters by 27 meters = 215.333

that means that you have 215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left (0.333 x 27 = 9)

Answer:

Bagels are 4 and Muffins are 2

Step-by-step explanation:

solve the system of equations

Answer:

Bagels are 4 and the muffins are 2 or the first answer

Step-by-step explanation:

2b+m=10

3b+m=14

we can subtract the equations

-b=-4

multiply both sides by -1 to get

b=4 meaning a bagel is four dollars

we can then subsitute this

2(4)+m=10

8+m=10

subtract 8 from both sides

m=2

subsitute these into the second equation to check

3(4)+(2)=14

12+2=14

14=14

Therefore the answer is Bagels are 4 and the muffins are 2 or the first answer

What is the image of the point (7,-5) after a rotation of 270° counterclockwise
about the origin?

Answers

Answer:

(-5, -7)

Step-by-step explanation:

if you rotate the point by 270 degrees counterclockwise, you get (5,-7) and I'm guessing image is another way to say reflection so after it is reflected then the point would be (-5,-7)

(-7,5) is the correct answer because 270 degrees counter clockwise is y,-x

Find the inequality represented by the graph

Answers

Answer:

y ≥ 1/2x

Step-by-step explanation:

Given the following inequality, we know that y must be greater than or equal to x because the line is not dashed, and is shaded above the line.

Now to find the equation just pretend that this is just a normal linear equation, and solve for the equation.

So since the y intercept is 0, and there is a rise of 1 for a run of 2 or 1 unit up every two units to the right, the corresponding linear equation is y = 1/2x.

Now since this is an inequality where y is greater than or equal to x.

y = 1/2x → y ≥ 1/2x

77th term for -10,-8,-6

Answers

9514 1404 393

Answer:

 142

Step-by-step explanation:

The first term of this arithmetic sequence is -10. The common difference is -8-(-10) = 2. The n-th term is ...

  an = a1 +d(n -1)

  an = -10 +2(n -1) = 2n -12

Then the 77th term is ...

  a77 = 2(77) -12 = 154 -12

  a77 = 142

The 77th term is 142.
