f(x) =  \dfrac{x}{2} - 2

g(x) = 2x^2 + x - 3

(f + g)(x) =  \dfrac{x}{2} - 2+ 2x^2 + x - 3

(f + g)(x) = 2x^2 + \dfrac{3}{2}x - 5

Use the first and last data points to find the slope intercept equation of a trend line.
andriy [413]

Answer:

y = \frac{16}{3}x-79

Step-by-step explanation:

From the given table,

Two points are (1, 15) and (7, 47)

If the two points (x_1,y_1) and (x_2,y_2) are lying on a line then slope 'm' of the line will be,

m = \frac{y_2-y_1}{x_2-x_1}

   = \frac{47-15}{7-1}

   = \frac{32}{6}

   = \frac{16}{3}

Let the equation of a line passing through (h, k) is,

y - h = m(x - k)

If the line passes through (1, 15)

y - 1 = \frac{16}{3}(x-15)

y = \frac{16}{3}x-\frac{16}{3}(15)+1

y = \frac{16}{3}x-80+1

y = \frac{16}{3}x-79

3 days. If every day he runs 10 laps then that would be 4000 meters. 1 kilometer is equal to 1000 meters. That means everyday he runs 4 kilometers. Then after 3 days he would have ran 12 kilometers.

What is 3/4divided by3/8​
guapka [62]

Answer:

3/4 divided by 3/8 equals 2

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

34×83=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

3×84×3=2412

Since 24 divided by 12 equals 2
