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}

anygoal [31]

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
