Answer:

A, C and D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y - intercept )

here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = 3 + c ⇒ c = 4 - 3 = 1

y = - 3x + 1 ← in slope- intercept form → C

Add 3x to both sides

3x + y = 1 ← in standard form → A

-----------------------------------------------------------

The equation of a line in slope- intercept form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - 3 and (a, b) = (- 1, 4), thus

y - 4 = - 3(x + 1) ← in point- slope form → D

The earning of the salesperson is an illustration of a linear function.

The possible functions in the two scenarios are: $\mathbf{I(s) = 0.1s + 2500}$ and $\mathbf{I(s) = 0.05s + 2000}\\$

The function is given as:

$\mathbf{I(s) = 0.1s + 2000}$

When the base salary is increased, a possible function is:

$\mathbf{I(s) = 0.1s + 2500}$

This is so, because 2500 is greater than 2000

When the commission rate is decreased, a possible function is:

$\mathbf{I(s) = 0.05s + 2000}\\$

This is so, because 0.05 is less than 0.1

So, the possible functions in the two scenarios are:

$\mathbf{I(s) = 0.1s + 2500}$ and $\mathbf{I(s) = 0.05s + 2000}\\$

See attachment for the graphs of both functions

The measures of the angles of a triangle are shown in the figure below. Solve for x.

ryzh [129]

(3x + 13) + (8x + 14) + 109 = 180°

(3x + 13) + (8x + 14) = 71°

11x + 27 = 71°

11x = 44°

x = 4

Find a number halfway between 2 1/2 and 1 1/3

kvasek [131]

Answer:

23/12

Step-by-step explanation:

2 1/2 = 5/2(3/3) = 15/6

1 1/3 = 4/3(2/2) = 8/6

15/6 - 8/6 = 7/6

7/6(1/2) = 7/12

16/12 + 7/12 = 23/12
