Answer:

see explanation

Step-by-step explanation:

Substitute the given values of x into f : x → $\frac{3}{7}$ x + 4

x = - 14 → ( $\frac{3}{7}$ × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2

x = 28 → ( $\frac{3}{7}$ × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16

x = $\frac{7}{8}$ → ( $\frac{3}{7}$ × $\frac{7}{8}$ ) + 4 = $\frac{3}{8}$ + 4 = $\frac{3}{8}$ + $\frac{32}{8}$ = $\frac{35}{8}$

x = - $\frac{2}{9}$ → ( $\frac{3}{7}$ × - $\frac{2}{9}$ ) + 4 = ( $\frac{1}{7}$ × - $\frac{2}{3}$ ) + 4 = - $\frac{2}{21}$ + $\frac{84}{21}$ = $\frac{82}{21}$

Paladinen [302]

Answer:

1. Using the exponent rule (a^b)·(a^c) = a^(b+c) ...

$\left(-2x^3y^4\right)\left(5x^9y^{-2}\right)=(-2)(5)\left(x^{(3+9)}y^{(4-2)}\right)\\\\=-10x^{12}y^{2}$

Simplify. Write in Scientific Notation

2. You know that 256 = 2.56·100 = 2.56·10². After that, we use the same rule for exponents as above.

$8 \left(32\times 10^{11}\right)=(8)(32)\times 10^{11}=256\times 10^{11}=2.56\times 10^{13}$

3. The distributive property is useful for this.

(3x – 1)(5x + 4) = (3x)(5x + 4) – 1(5x + 4)

... = 15x² +12x – 5x –4

... = 15x² +7x -4

4. Look for factors of 8·(-3) = -24 that add to give 2, the x-coefficient.

-24 = -1×24 = -2×12 = -3×8 = -4×6

The last pair of factors adds to give 2. Now we can write

... (8x -4)(8x +6)/8 . . . . . where each of the instances of 8 is an instance of the coefficient of x² in the original expression. Factoring 4 from the first factor and 2 from the second factor gives

... (2x -1)(4x +3) . . . . . the factorization you require
