For (h+g)(x) you just add the two functions:

(h+g)(x) = 4x + 2x^2

For (h•g)(x) you multiply them:

(h•g)(x) = 4x • 2x^2 = 8x^3

For (h-g)(x) you subtract them:

(h-g)(x) = 4x - 2x^2

For (h-g)(-2) you sub -2 into the equation we just created:

(h-g)(-2) = 4(-2) - 2(-2)^2
(h-g)(-2) = -8 - 2(4)
(h-g)(-2) = -8 - 8
(h-g)(-2) = -16

The equation of line is y = 92x – 182631. The slope is 92 and the y-intercept is the negative 182631. And the health expenditure in 2010 will be 2289.

<h3>What is the equation of a line passing through two points?</h3>

Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

$\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)$

In MODE, (second line), fix the number of decimal places to be 2.

Then the slope and the y-intercept values of the Lin Reg line will round to the nearest hundredth.

(x₁, y₁) → (1997, 1093)

(x₂, y₂) → (2002, 1553)

Then we have

y – 1093 = [(1553 – 1093) / (2002 – 1997)] (x – 1997)

y – 1093 = [460 / 5] (x – 1997)

y – 1093 = 92 (x – 1997)

y = 92x – 182631

If x = 2010, then the value of y will be

y = 92 × 2010 – 182631

y = 184920 – 192631

y = 2289

Help please I am a bit confused on this.

Anit [1.1K]

Because there are 4 inside angles the sum of the four angles must equal 360 degrees.

Add the angles to equal 360:

4x + 3x + 2x + 3x = 360

Simplify:

12x = 360

Solve for x by dividing both sides by 12:

x = 360 /12

x = 30

Now you have x, solve for each angle:

ABC = 4x = 4 x 30 = 120 degrees.

BCD = 3x = 3 x 30 = 90 degrees.

CDA = 2x = 2x 30 = 60 degrees.

DAB = 3x = 3 x 30 = 90 degrees.

C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.

If a pound of rolled oats costs $12, how many ounces can be bought for $4.35?

Tpy6a [65]

5.8 ounces of oat can be bought for $4.35

<h3>Ratio and proportion</h3>

Fractions are written as the ratio of two expression

According to the question a pound of rolled oats costs $12, this can be expressed as;

1 pound of oat = $12

since 1 pound = 16 ounces, hence;

16 ounces = $12

Determine the amount bought for $4.35

x = $4.35

16/x = 12/4.35

12x = 69.6

x = 5.8 ounces

Hence 5.8 ounces of oat can be bought for $4.35

Shryia read a 481-page-long book cover to cover in a single session, at a constant rate. After reading for 1.51 hours, she had 4

leonid [27]

Answer:

It took Shryia 9.31 hours to read the entire book.

Step-by-step explanation:

i) total number of pages = 481 page

ii) pages left to read = 403 pages

iii) pages read = 481 - 403 = 78 pages

iv) time taken to read 78 pages = 1.51 hour

v) Shyria was reading at a $= \frac{78\hspace{0.1cm}pages}{1.51\hspace{0.1cm}hours} = 51.66\hspace{0.1cm} pages \hspace{0.1cm}per\hspace{0.1cm}hour$

vi) It took Shryia $= \frac{481\hspace{0.1cm}pages}{51.66pages\hspace{0.1cm}per\hspace{0.1cm}hour} = 9.31\hspace{0.1cm} hours$
