We are given traingle ABC and Triangle DEF.

Angle <A is congruent to Angle <D

Angle <B is congruent to Angle <E

Angle <C is congruent to Angle <F.

If two pairs of corresponding angles are congruent to each other, then the triangles are similar by Angle-Angle Similarity.

By Angle-Angle similarity postulate triangle ABC and triangle DEF are similar.

Therefore, option C is correct option.

<h3>C. Similar - AA.</h3>

What transformation of the parent function f(x) is made to get 4f(x+2)

LenKa [72]

Answer: A vertical stretch of 4 and a translation of -2 units in the x-direction.

Step-by-step explanation:

Changes of the parent function can be written, in this case as af(x)(x - k) where a is the stretch factor and k is the movement left or right on the x-axis.

In this case, a = 4 and k = 2. Since the k is negative, the function will be moved -2 units on the x-axis.

Given the system of equations presented here:

Nata [24]

2x + 4y = 14
4x + y = 20......multiply by -4
----------------
2x + 4y = 14
-16x - 4y = -80 (result of multiplying by -4)
---------------add
-14x = -66....as u can see, ur y's cancel out

so ur answer is : 1st answer choice <==

** and just so u know, u could have multiplied the 1st equation by -2, and it would have cancelled out ur x's

Lee spent $36 to purchase a combination of drinks, sandwiches, and chips for himself and his friends. A drink costs $2, a sandwi

valkas [14]

2x+4y+0.50z=36 represents the situation.

Step-by-step explanation:

Let,

Drinks = x

Sandwich = y

And,

Chips = z

Total amount on these items = $36

According to the statement;

$x(cost\ of\ one\ drink)+y(cost\ of\ one\ sandwich)+z(cost\ of\ one\ chips)=\ Total\ amount\ spent\\2x+4y+0.50z=36$

2x+4y+0.50z=36 represents the situation.

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for t

Marizza181 [45]

Answer:

$a_n = -2 + n$ is an expression which describe the given sequence

Step-by-step explanation:

Arithmetic sequence states that a sequence where the difference between each successive pair of terms is the same.

The general rule for the arithmetic sequence is given by;

$a_n =a_1+(n-1)d$ ......[1]

where

$a_1$ represents the first term

d represents the common difference

and n is the number of terms;

Given sequence: -1 , 0 , 1 , 2 , .....

This is an arithmetic sequence with common difference

Since,

0-(-1) = 1

1-0 =1

2-1 = 1 ....

Here, $a_1 = -1$

Substitute the value of $a_1 = -1$ , d =1 in [1] we get

$a_n = -1 +(n-1)(1)$

$a_n = -1 + n -1 = -2 +n$

Therefore,an expression which describe the given sequence is, $a_n = -2 + n$
