 HELP!!! △ABC has interior angles with measures 130°, x°, and 15°, and △DEF has interior angles with measures 35°, 15°, and y°.

Using the given information, which statement is true?
1) The triangles are not similar because x≠y .

2) The triangles are not similar because x≠15 .

3) The triangles are similar because they each have an interior angle with measure 15°.

4) The triangles are similar because y=130 and there are three pairs of congruent angles.

Algebraically show that each of the given combinations are equivalent to the given functions.
BlackZzzverrR [31]

Answer:

Yes they ate Equivalent

Step-by-step explanation:

Given the expression

h(x) = - 3x – 1;j(x) = – 7x + 11 ; k(x) = 21.22 – 262 – 11

H(x)•j(x) = (-3x-1)(-7x+11)

H(x)•j(x) = (-3x)(-7x)-3x(11)-1(-7x)(-1)(11)

H(x)•j(x) = 21x²-33x+7x-11

H(x)•j(x) = 21x²-26x-11

This shows that H(x)•j(x) = k(x)

Find the value of d that makes the equation true:
hichkok12 [17]
To answer this, you need to get "d" on one side by itself. To do this, add 8 to both sides of the equation.

d- 8 + 8 = 5 + 8
-8 and +8 cancel out leaving:
d = 13

Your answer is d = 13

For the following set of 20 numbers:
patriot [66]

Answer:

I cannot answer all of this, so I will only answer what I can:

Q1: 13

Q3: 22.5

IQR: 13.5

IQR(1.5): 20.25

Q3 + IQR(1.5) = 43

Q1 - IQR(1.5) = -7.25

I don't know if my calculations are all right but I hope this helps! :)

Evaluate f(x) = 2|x – 5| for f(–5) and f(0).
Elanso [62]

Answer:

f(–5) = 20, f(0) = 10

Step-by-step explanation:

f(-5):

f(-5) = 2|-5 -5|

f(-5) = 2|-10|

f(-5) = 2(10)

f(-5) = 20

f(0):

f(0) = 2|0 - 5|

f(0) = 2|-5|

f(0) = 2(5)

f(0) = 10
