The table shows revenue R (in millions of dollars) of a company when it spends A (in millions of dollars) in advertising.

Orlov [11]

Advertising is x and revenue is y

(0,2)(2,6)
slope = (6 - 2) / (2 - 0) = 4/2 = 2

y = mx + b
slope(m) = 2
(0,2)...x = 0 and y = 2
now we sub and find b, the y int
2 = 2(0) + b
2 = b

so ur equation is : y = 2x + 2

spends 10 mill on advertising.....so x = 10
y = 2x + 2
y = 2(10) + 2
y = 20 + 2
y = 22.....so the revenue (y) of the company is 22 (million)

FIND THE VALUE OF X AND Y.(ordered pairs)<br><br>(x+y,0)=(8,x-y)

Aliun [14]

Step-by-step explanation:

We know that...

x+y (from the first pair) corresponds to 8(in the second pair)..

0 (from the first pair) corresponds to x-y (in the second pair)..

Hence,

$x + y = 8 \\ x - y = 0$

By simply adding the two equations we get,

$2x = 8 \\ x = 4$

Hence,

By substituting x=4, we get that y=4

Hence,

x=y=4
