Jika F(x) = 7x⁴ - 20x² + 15x + 2, nilai F(-2) = A. -11 B. 0 C. 4 D. 7 E. 24

The given condition is:
If 5x + 7 = 2x =1, then 3x + 7 = -1
=> This given equation represent a subtraction property of equality.
=> 5x +7 =2x-1
=> 5x – 2x + 7 = -1
=> 3x + 7 = -1
What we did was we subtracted 2x from 5x to get the 3x
Subtraction property of equality is a mathematical process in where we subtract numbers from both sides that contains the same expression.
Like 5x and 2x, since they have the same equation, we both subtracted both numbers and the rest remains as it is.

The true conditional statement illustrates the Subtraction Property of Equality. This property states that subtracting the same value from both sides of an equation maintains equality. In this case, the operation of subtracting 2 x allows us to derive 3 x + 7 = − 1 .

Diketahui fungsi $$ F(x) = 7x^4 - 20x^2 + 15x + 2 $$. Kita diminta mencari nilai $$ F(-2) $$.Langkah perhitungan:$$F(-2) = 7(-2)^4 - 20(-2)^2 + 15(-2) + 2$$Hitung pangkat terlebih dahulu:$$(-2)^4 = 16, \quad (-2)^2 = 4$$Substitusi:$$F(-2) = 7 \times 16 - 20 \times 4 + 15 \times (-2) + 2$$$$= 112 - 80 - 30 + 2$$$$= (112 - 80) - 30 + 2$$$$= 32 - 30 + 2$$$$= 4$$Jadi, nilai $$ F(-2) = 4 $$.**Jawaban yang benar adalah C. 4**.
