Answer:

The answer is below

Step-by-step explanation:

BE and CF are two equal altitudes of triangle ABC using RHS congruence rule prove that triangle ABC is isosceles.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.

The RHS congruence rule states that if the hypotenuse and one leg of one triangle is equal to the hypotenuse and leg of another triangle; then the two triangles are equal. Two triangles are equal if they have three equal angles and three equal sides.

We have right angle triangles BEC and BFC

BE = CF (given)

CB = BC (both triangles have the same hypotenuse)

Hence ΔBEC = ΔBFC (RHS congruence rule)

Therefore; ∠BCE = ∠FBC (congruence theorem)

Since two angles of triangle ABC are equal (∠B = ∠C), therefore triangle ABC is an isosceles triangle and AB = AC

Answer:

a=542

Step-by-step explanation:

you welcome have a good day

Answer:

the answer will be a=524

Step-by-step explanation:

Answer:

an = 4n - 1

a1 = 3

a2 = 7 = 3 + 4

a3 = 11 = 3 + 4.2

a4 = 15 = 3 + 4.3

a5 = 19 = 3 + 4.5

.....

=> this is a arithmetic with a1 = 3 and d = 4

=> an = 3 + 4(n - 1) = 4n - 1

Answer:

-21y+7

Step-by-step explanation:

-7(3y-1) = 3y(-7) -1(-7) = -21y+7

Answer:

-21y + 7

Step-by-step explanation:

Just times - 7 with 3y then - 7 times with - 1

Answer:

D. (x, y) → (x, −y)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.

The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.

The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.

The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.

The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.

Answer:

m = 12

Step-by-step explanation:

Given

Answer:

10 dollars

Step-by-step explanation:

4 / 2.80 = 1.42857142857

so that means 1.42857142857 is the cost of one apple.

1.42857142857 x 7 = 10

so your answer is,

it costs $10 for 7 apples.

Step-by-step explanation:

A 2-column table with 4 rows. Column 1 is labeled Store with entries A, B, C, D. Column 2 is labeled Advertised Bread Prices with entries 3 loaves for 5 dollars and 94 cents, 4 loaves for 7 dollars and 80 cents, 5 loaves for 10 dollars and 5 cents, 6 loaves for 12 dollars and 12 cents.

Camillo is making gourmet peanut butter and jelly sandwiches for a food challenge.

PLS HELP ASAP!!What is the unit price of a loaf of bread at each store?

Store A:

Store B:

Store C:

Store D:

Solution:

The unit price of an item is the price for a single unit of measure of that item. It is measured in price / unit measure.

unit price of a loaf of bread at each store = cost of the loaf of bread / number of loaves

For store A, unit price = $5.94 / 3 loaves = $1.98 per loaf

For store B, unit price = $7.80 / 4 loaves = $1.95 per loaf

For store C, unit price = $10.50 / 5 loaves = $2.10 per loaf

For store D, unit price = $12.12 / 6 loaves = $2.02 per loaf

Answer:

yup the person above me is right but for C its $2.01 :>
