Let P(x) be the statement "x is a clear explanation," ????(x) be the statement "x is satisfactory," ????(x) be the statement "x
Flauer [41]

Answer:

a P(x) = Q(x)

b. R(x) = Q(x)

c. R(x)  = P(x)

d. Yes

Step-by-step explanation:

This is a statement of logical connectives.

a P(x) = Q(x)

b. R(x) = Q(x)

c. R(x)  = P(x)

d. Yes, (c) follows from (a) and (b)

Reasoning:

(c) is equivalent to ∀x ¬ P(x) ∨ Q(x)

Proof:

Follow the tautology (X→Υ) Ξ(¬x∨Υ)

This gives X: R(x) ∧ ¬ P(X)

This makes sense because every point on the gold line is a solution to the equation
y
=
1
2
x
+
3
y=
2
1
​
x+3start color #e07d10, y, equals, start fraction, 1, divided by, 2, end fraction, x, plus, 3, end color #e07d10, and every point on the green line is a solution to
y
=
x
+
1
y=x+1start color #0d923f, y, equals, x, plus, 1, end color. So, the only point that's a solution to both equations is the point of intersection

Answer:

15 in^2

Step-by-step explanation:

Find the area of the vertical rectangle

A = l*w

A = 6*2 = 12 in^2

Now find the area of the horizontal rectangle

A = l*w

   = 3*1 = 3in^2

Add them together

12+3 =15 inch^2
