Hello Brainly user,

As shown on the picture line I is x=3....

if you take the 7,0 line and if you go down 90 degree clockwise it would line up with line I so therefore, the answer is A.

Hope i helped and i was exited and glad to help you and im here for anymore answer you might have

Find the area of the region in two ways. a. Using integration with respect to x. b. Using geometry. 9-x

Natali [406]

Answer: hello your question is incomplete attached below is the complete question

answer :

a) $\int\limits^3_0 {(10-x)-(x+4)} \, dx$ ( option D )

b) A = 1/2 (6)(3) ( option B )

c) Area of shaded region = 9

Step-by-step explanation:

a) Using integration with respect to x

Area = $\int\limits^7_4 {(y-4)} \, dy + \int\limits^a_7 {(10-y)} \, dy$ ( note a = 10 )

= y^2/2 - 4y |⁷₄ + 10y - y^2/2 |¹⁰₇

= 33/2 - 12 + 30 - 51/2 = 9

hence the best integral from the options attached is option D

$\int\limits^3_0 {(10-x)-(x+4)} \, dx$

= [ 10x - x^2 /2 - x^2/2 - 9x ] ³₀

= 30 - 9/2 - 9/2 - 12 = 9

b) Using Geometry

Area = 1/2 * base * height

= 1/2 * 6 * 3

= 9

Complete the equation of the line whose slope is –2 and y-intercept is (0.3).

natima [27]

Hi!

Using y = mx + b form, where m is the slope and b is the y-intercept, we get the equation: y = -2x + 0.3

Hope this helps! :D

What is the value of 2x^3+7x^2-19x-6 if the value of x is -1

Paul [167]

Answer:

-40

Step-by-step explanation:

Let's input x into all of the slots.

$-2^{2}+-7^{2}+19-6$

Now, let's solve!

$-4-49+19-6$

$-40$

So, the answer is -40!
