Solve 5(2x + 4) = 15. Round to the nearest thousandth.<br> PS: x+4 is the power for 2

lilavasa [31]

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Let's solve for x ~

$\qquad \sf \dashrightarrow \: 5(2x + 4) = 15$

$\qquad \sf \dashrightarrow \: (5 \times 2x) + (5 \times 4) = 15$

$\qquad \sf \dashrightarrow \: 10x + 20 = 15$

$\qquad \sf \dashrightarrow \: 10x + 20 - 20 = 15 - 20$

$\qquad \sf \dashrightarrow \: 10x = - 5$

$\qquad \sf \dashrightarrow \: \dfrac{10x}{10} = \dfrac{ - 5}{10}$

$\qquad \sf \dashrightarrow \: x = - \dfrac{ 1}{2}$

hence value of x is - 1/2

Write the slope intercept equation for this table

andrew-mc [135]

Answer:

y = 2x -4

Step-by-step explanation:

y2 - y1 / x2 - x1

-4 - (-6)/ 0 - (-1)

= 2

y = mx + b

y = -2x + b

-4 = -2(0) + b

-4 = 0 + b

-4 = b

So the equation is y = 2x -4
