Expand the function. f(x)=(x + 7)^3

Marta_Voda [28]

Answer:

$f(x) = {x}^{3} + 21 {x}^{2} + 147x + 343$

Step-by-step explanation:

$(x + 7 {)}^{3}$

${x}^{3} + 3 {x}^{2} \times 7 + 3x \times {7}^{2} + {7}^{3}$

${x}^{3} + {x}^{2} \times 7 + 3x \times 49 + 343$

${x}^{3} + 21 {x}^{2} + 147x + 343$

Therefore:

$f(x) = {x}^{3} + 21 {x}^{2} + 147x + 343$

Which is the graph of y- 3 = -2/3(x + 6)?

Olegator [25]

Answer:

put points on (1.5, 0) and (0, -1), then draw a continuous line through them

Step-by-step explanation:

y - 3 = -2/3(x + 6)

y - 3 = (-2/3)x - 4

y = (-2/3)x - 1

0 = (-2/3)x - 1

1 = (-2/3)x

x = 3/2 = 1.5

y = (-2/3)(0) - 1

y = -1
