Answer:

(4, 4 )

Step-by-step explanation:

Given the 2 equations

y = x² - 6x + 12 → (1)

y = 2x - 4 → (2)

Substitute y = x² - 6x + 12 into (2)

x² - 6x + 12 = 2x - 4 ( subtract 2x - 4 from both sides )

x² - 8x + 16 = 0 ← in standard form

(x - 4)² = 0 ← in factored form

x - 4 = 0 ⇒ x = 4

Substitute x = 4 into (2) for corresponding value of y

y = 2(4) - 4 = 8 - 4 = 4

Solution is (4, 4 )

Help ! Inductive and deductive reasoning differ in which way? A) Conclusions drawn using deductive reasoning are always false, w
kykrilka [37]

Answer:

B) Conclusions drawn using inductive reasoning are always valid, while conclusions drawn using deductive reasoning may or may not be valid.

Step-by-step explanation:

Inductive reasoning uses logic and uses more evidence to draw conclusions. In deductive reasoning, WE decide whether a deductive statement is true by assessing the strength of the link between the premises and the conclusion. But some deductive reasoning may appear to make sense without pointing to a truth

Fantom [35]

Answer:

The right response is Option c ($185,870,742).

Step-by-step explanation:

Given:

n = 30

r = 5.4%

or,

 = 0.054

Periodic payment will be:

R = \frac{360000000}{30}

   =12000000 ($)

Now,

The present value will be:

= R+R(\frac{1-(1+r)^{-n+1}}{r} )

By substituting the values, we get

= 12000000+12000000(\frac{1-(1+0.054)^{-30 + 1}}{0.054} )

= 12000000+12000000\times 14.4892

= 185,870,742 ($)
