ANSWER-the distance is (6,8)
if you set the equation up from 2-8=6 which is your x value and 4-12=8 is your y value it should also give you your Distance between the two points

leonid [27]

Answer: 250 mi

Step-by-step explanation:

Here we can think in a triangle rectangle:

The distance from Birmingham to Atlanta is roughly 150 mi, and this is one of the cathetus.

And the distance from Birmingham to Nashville is roughly 200 mi, this is the other cathetus of the triangle.

Now, the distance from Atlanta to Nashville will be the hypotenuse of this triangle rectangle.

Now we can apply the Pythagorean's theorem:

A^2 + B^2 = H^2

Where A and B are the cathetus, and H is the hypotenuse:

Then:

H = √(A^2 + B^2)

H = √(150^2 + 200^2) mi = √(62,500) mi = 250 mi

Then the estimated distance from Atlanta to Nashville is 250 mi

Can I Have The Answer? It’s a disgusting hard homework, and I would really appreciate it if you helped me.

Semenov [28]

Answer:

-2c + 8d - 6

-6 + 5d - 2c + 3d

Step-by-step explanation:

When multiplying terms in a bracket, you need to multiply the term outside the bracket to all the terms in the bracket.

- $\frac{2}{5}$ (15-20d+15c) = (- $\frac{2}{5}$ × 15) + (- $\frac{2}{5}$ × -20d) + (- $\frac{2}{5}$ × 15c)

Two minuses make a plus. One minus and one plus make a minus.

(- $\frac{2}{5}$ × 15) + (- $\frac{2}{5}$ × -20d) + (- $\frac{2}{5}$ × 15c) = (-6) + (8d) + (-2c)

Note that the terms can be presented in any order and still be correct.

(-6) + (8d) + (-2c) = -6 + 8d - 2c

Let us go through the options to see which ones are correct:

-2c + 8d - 6: Since all the terms are there, this option is correct!

-c + 40d - 8: Since none of the terms is there, this option is wrong.

-4c + 40d - 8: Since none of the terms is there, this option is wrong.

-3c + 8d - 3: Since (-3c) and (-3) are not the correct terms, this option is wrong.

-6 + 5d - 2c + 3d: If we evaluate the like terms (5d and 3d), the final answer would be -6 + 8d - 2c so this option is also correct!

What are the coordinates of each point? Point B is the image of A after a rotation of 1800 using (0, 0) as center. Point C is th

sukhopar [10]

Answer:

See Below

Step-by-step explanation:

Ok, so you have point A (-4,3)

To get point B, you rotate 180 degrees around the origin

Point A is in Quadrant 2, So . . Point B is in Quad 4

Quad 4 (+, -) (switch the signs) Point B (4,-3)

Now Point C

Point C is the image of A after a translation two units to the right, then a reflection using the x-axis.

So add two to the x (-4 +2, 3) = (-2,3)

Now, to reflect over the x-axis you switch the sign for the y

Point C (-2,-3)

Last one, Point D

Point D is the image of A after a reflection using the y-axis, then a translation two units to the right.

To reflect over the y-axis, you switch the signs for the x

(4,3)

Now add 2 to the x

(4+2, 3) = Point D (6,3)

A (-4,3) B(4,-3) C (-2,-3) D (6,3)

Q11 Ratio and Proportion

Amanda [17]

Answer:

Proportion of the flowers that are red tulips = $\frac{2.57}{11}$

Step-by-step explanation:

Given - There are some flowers in a shop. Each flower is either red or

yellow. Each flower is either a tulip or a rose. For these flowers

number of tulips : number of roses = 6:5 and number of red tulips :

number of yellow tulips = 3:4

To find - Work out the proportion of the flowers that are red tulips.

Proof -

Let Total number of flowers in a shop = 11x

As given, number of tulips : number of roses = 6:5

⇒Total number of tulips in a shop = $\frac{6}{11}.11x$ = 6x

Total number of roses in a shop = $\frac{5}{11}.11x$ = 5x

Now,

As given, number of red tulips : number of yellow tulips = 3:4

⇒Total number of red tulips = $\frac{3}{7}.6x$ = 2.57x

Total number of yellow tulips = $\frac{4}{7}.6x$ = 3.43x

∴ we get

Proportion of the flowers that are red tulips = $\frac{2.57x}{11x}$ = $\frac{2.57}{11}$
