Step-by-step explanation:

(x+1)/2=21/14

cross multiply

14(x+1)=21(2)

14x+14=42

14x=42-14

14x=28

x=2

A company manufactures and sells shirts. The daily profit the company makes

Rom4ik [11]

Answer:

$f(-5) = -150$

Meaning: If the company sells -5 shirts, they would make a profit of -150 dollars. This interpretation of loss in the context of the problem

$f(7) = -30$

Meaning: If the company sells 7 shirts, they would make a profit of -30 dollars. This interpretation of loss in the context of the problem

$f(10.5) = 5$

Meaning: If the company sells 10.5 shirts, they would make a profit of 5 dollars. This interpretation of profit in the context of the problem

Step-by-step explanation:

Given

$f(x) = 10x - 100$

Required

Fill in the gap

$f(-5) = 10 * -5 -100$

$f(-5) = -50 -100$

$f(-5) = -150$

$f(7) = 10 * 7 - 100$

$f(7) = 70 - 100$

$f(7) = -30$

$f(10.5) = 10 * 10.5 - 100$

$f(10.5) = 105 - 100$

$f(10.5) = 5$

Which ordered pair would form a proportional retationship with the points in the graph?

shtirl [24]

Answer:

(9, 6)

Step-by-step explanation:

the given points are

(3, 2)

(6, 4)

so, can you see, how the sequence continues ?

I see immediately that for every 3 additional units of x we add 2 units of y.

so, yes, the next point in the sequence is

(6 + 3, 4 + 2) = (9, 6).

so, this point (or ordered pair) follows the same ratio or proportional relationship between x and y as the points already in the graph.

in other words, they are on the same line following the same slope ("y coordinate change / x coordinate change" when going from one point on the line to another).
