Answer:

  D.

Step-by-step explanation:

There is nothing in the figure to indicate the triangles are isosceles. This eliminates answer choices A, B, C.

Answer choice D is a required step in the proof, but only gets part of the way. The triangle similarity means ...

  SQ/PQ = TQ/RQ

From here, you need to decompose each of the sides PQ and RQ into parts. Then you can get to the desired relationship.

  (PQ -PS)/PQ = (RQ -RT)/RQ . . . segment sum theorem

  1 - PS/PQ = 1 -RT/RQ . . . . . . . do the division

  -PS/PQ = -RT/RQ . . . . . . . . subtract 1 (subtraction property of equality)

  PS/PQ = RT/RQ . . . . . . . . multiply by -1 (multiplication property of equality)

Guys I really need some help with this one!

Answer:

f( 1 ) = 3

Step-by-step explanation:

Given the linear function, f(x) = -4x + 7, we could easily find f( 1 ) by substituting the value of the input, x = 1, into the function.

f(x) = -4x + 7

f( 1 ) = -4( 1 ) + 7

f( 1 ) = -4 + 7

f( 1 ) = 3

Therefore, the output value is f( 1 ) = 3.

If QRS TUV, which congruences are true by CPCTC? Check all that apply.
Morgarella [4.7K]

It is given thatΔ QRS ≅Δ TUV

Out of all the given options

(C) QS= TV [C P C T}

(D) QR =TU

(E) S = V

(F) R= U

C, D,E, F are correct options.

Because when two triangles are congruent their corresponding parts are equal.

CPCT means corresponding parts of congruent triangles.

All these options are congruent by CPCT.

Side QR is congruent to TU.

Side Q S  is congruent to TV.

Angle S is Congruent to Angle V.

Angle R is congruent to Angle U.

The meaning of congruency of shapes is that the two or many more shapes are identical.

Equivalent fractions for 9/11, 15/17, and 2/3 using the least common denominator.
TiliK225 [7]
The (small) challenge here is to determine what the LCD is.  Since 11, 17 and 3 are all prime, we find the LCD by multiplying them together:  561.

Then 9/11= 459/561; 15/17 = 495/561; and 2/3 = 375/561.
