The fact family model represent 3+14=17

Mathematics
1 answer:
Kruka [31]3 years ago
7 0

Answer:

Step-by-step explanation:

A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts. For example, you can form a fact family using the three numbers 10, 2, and 12: 10 + 2 = 12, 2 + 10 = 12, 12 − 10 = 2, and 12 − 2 = 10

Given: <PQR is a right angle Prove: <PQS and <SQR are complemantary​
amm1812

Answer:

see the explanation

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠PQS+m∠SQR=m∠PQR ----> equation A (by Addition Angle Postulate)

we have that

m∠PQR=90° ----> equation B given problem (because is a right angle)

substitute equation B in equation A

m∠PQS+m∠SQR=90°

Remember that

Two angles re complementary is their sum is equal to 90 degrees (Definition of complementary angles)

therefore

m∠PQS and m∠SQR are complementary angles

<h2>A)</h2>

\\\\\text{Given that,} ~ g(x) = \dfrac 13 x + 5 \\\\\text{Write g(x) as}~ y = \dfrac 13 x +5 \\\\\text{Replace x with y and then solve for y:}\\\\~~~~~~~x = \dfrac 13y +5 \\\\\implies 3x = y + 15~~~~~~~~~~~~~~~~~~~;[\text{Multiply both sides by 3]}\\\\\implies y = 3x -15\\\\\implies g^{-1} (x) = 3x -15 \\

<h2>B)</h2>

\left(g \circ} g^{-1} \right)(x)\\\\=g\left(g^{-1}(x) \right)\\\\=g(3x-15)\\\\=\dfrac 13\cdot(3x-15)+5\\\\=x -5 +5\\\\=x
