The sum of the following algebraic expression 2x + 15, 7-8x and 3x - 41 is 30 find the value of x..

Ksju [112]

$\\ \tt \longmapsto2x + 15 + 7 - 8x + 3x - 41 = 30 \\ \\ \tt \longmapsto 2x - 8x + 3x + 15 + 7 - 41 = 30 \\ \\ \tt \longmapsto - 3x - 19 = 30 \\ \\ \tt \longmapsto 3x + 19 = - 30 \\ \\ \tt \longmapsto 3x = - 30 -19 \\ \\ \tt \longmapsto 3x = - 49 \\ \\ \tt \longmapsto x = - \frac{49}{3}$

C.is decrease by 1 foot every 500 miles D. Is decrease by 1 foot every 1000 miles

Tasya [4]

Answer:

Option A

Step-by-step explanation:

Slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Line shown in the graph is passing through two points (2, 8000) and (4, 7000).

Therefore, slope of the given line = $\frac{8000-7000}{2-4}$

= -500 feet per mile

Which means, altitude decreases by 500 ft every mile.

(Negative sign represents the decrease)

Option A is the correct option.

Answer:

-243

Step-by-step explanation:

${( - 3)}^{ - 5} = \frac{1}{x} \\ \\ \therefore \: \frac{1}{ {( - 3)}^{ 5} } = \frac{1}{x} \\ \\ \therefore \: {( - 3)}^{ 5} = x \\ \\ \therefore \: - 243 = x \\ \\ \huge \red{ \boxed{\therefore \: x = - 243}}$
