3x+2y=6 and y=1/3x-11 perpendicular or parallel

Answers

Answer 1

Answer: To determine if two lines are parallel or perpendicular, you have to look at the slopes. For the line y=kx+b, k is the slope.

For two lines y=k1x+b1 and y=k2X+b2 ,When K1=K2, two lines are parallel; when K1=-1/k2, two lines are perpendicular. It doesn't matter whatever b1, b2 are. Hence to save time, you only need to calculate k1 and k2.

To calculate the slope k of any line, you have to change the equation to y=kx+b

For -y=3x-2, k=3/(-1)=-3 (you divide -1 on each side of =, but you don't need to calculate -2/(-1))

For -6X+2y=6, K=6/2=3 (you first move the -6x to right side, it becomes 6x, then divide by 2)

Now you can get the answer: The two lines neither parallel nor perpendicular.

REFLECTION/ ROTATION QUESTION!

Answers

Answer:

reflecting over the X-axis

Answer: Reflection of 90° clockwise.

90° reflection would displace the rectangle from its original position.

For the other choices, a reflection over either axis will not affect the rectangle because its vertices’ ordered pairs have 2’s.
A rotation of 180° will not affect the position of the shape.

What is the solution to the system of equations?

Help!!

Answers

Equation A find “m” and “b”:
“B” is the y-intercept when x = 0. They give this in the table as “-2” so b = -2
Find slope (m) = (-8)-(-2)/(-2)-0 = 3
Equation A is y = 3x - 2 (y = mx + b)
Equation B find “m” and “b”:
Find m = (-9)-(-5)/(-3)-(-1) = 2
To find be, plug in m, x, and y from ANY coordinates in table b into y = mx + b:
-9 = 2(-3) + b
-9 = -6 + b
b = -3
Equation b is y = 2x -3
Use substitution and substitute all of equation “b” for “y” in equation a:
2x - 3 = 3x - 2
Algebra: x = -1
Plug back into equation a:
y = 3(-1) -2
y = -5
x = -1
(-1, -5) final answer (B)

Complete the equation of the line whose slope is -5/3
and y-intercept is (0, -2).

Answers

Answer:

these are tough, it takes a lot of practice to get used to these, sooo

Step-by-step explanation:

we know the slope, m= -5/3, and we're given a point so use the point slope formula

y= mx + b

the point we are given is in this form (x,y)

then plug the information into our point slope formula

y = (-5/3) x + (-2)

y = -5x/3 -2

Answers

Answer:

eric=12

bill=16

Step-by-step explanation:

you can solve this using two simple algebraic equations. this is the key I will be using:

x=bill

y=Eric

x+y=28

x=y+4

since x is by itself in the second equation, I can replace the x in the first equation with y+4

(y+4)+y=28

subtract 4 from both sides

y+y=24

which is also 2y=24

divide both sides by two.

y=12

so now we know Eric is 12 years old.

using this, we can replace the "y" in the second original equation (x=y+4)

x=12+4

x=16

Bill is 16 years old.

Kip took out a loan for $750. He earned $60 in interest and his interest

Answer:

(b) 2 years

Step-by-step explanation:

The interest formula is ...

I = Prt . . . . interest rate r on principal P for t years

We can fill in the known values and solve for t.

60 = 750·0.04·t

60/30 = t = 2

The loan was repaid in 2 years.

For what value of k does the equation 6(x + 1) + 2 = 3(k5x + 1) + 3 have no solution?

Answers

Answer:

k = (6/15)

Step-by-step explanation:

The equation is:

6*(x + 1) + 2 = 3*(k*5*x + 1) + 3

To have no solutions, we need to have something like:

x + 7 = x + 4

where we can remove x in both sides and end with

7 = 4

So this equation is false, meaning that there is no value of x such that this equation is true, then the equation has no solutions.

First, let's try to simplify our equation:

6*(x + 1) + 2 = 3*(k*5*x + 1) + 3

6*x + 6 + 2 = 3*k*5*x + 3*1 + 3

6*x + 8 = 15*k*x + 6

if 15*k = 6, then the system clerly has no solution.

then:

k = 6/15

then we get:

6*x + 8 = (6/15)*15*x + 6

6*x + 8 = 6*x + 6

8 = 6

The system has no solutions.

5x² -60x + 160 = 0

x² - 12x + 32 = 0

Answer:

-x + 5y = 12

Step-by-step explanation:

Eliminate the fractional coefficient by multiplying both sides by 5:

Combine the constants: 5y = x + 12

Subtract x from both sides: -x + 5y = 12 This is in standard form

Three corners of a city bloc is located at (2,2) (2,-4) (-5,-4) on a coordinate plane what are the coordinates of the fourth corner

Answers

Answer:

(-5, 2)

Step-by-step explanation:

Three corners of a rectangular city block are located at (2,2), (2,-4) and (-5,-4) on a coordinate plane. What are the coordinates of the fourth Coordinate?

Solution:

A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. Also, all the angles are at 90 degrees.

Since the city block is rectangular in shape, therefore the fourth coordinate would have the same y coordinate as the point (2, 2) and it would also have the same x coordinate as (-5, -4).

Hence the fourth coordinate is (-5, 2)
