Answer:

(x,y) = 26/3 , 13/3

Step-by-step explanation:

y= -x +13

1.5x-2y+-x+13

simplify

x+y+13

25x-20y=130

eliminate one varable by adding the equations

-45y=-195

devide by 45 on both sides

y=13/3

sub y into the equation

x+13/3+13

solve

x=26/3

Nate is exponentially gaining Twitter followers! His current amount of followers is 146. His followers are increasing at a 24% r

Answer:

(a) Growth

$(b)\ y = 146(1.24)^x$

Step-by-step explanation:

Given

$a= 146$ -- current

$r = 24\%$ --- rate

Solving (a): Growth or decay

The question says his followers increases each day by 24%.

Increment means growth.

Hence, it is a growth problem

Solving (b): Equation to represent the scenario.

Since the rate represents growth, the equation is:

$y = a(1 + r)^x$

Substitute: $a= 146$ and $r = 24\%$

$y = 146 * (1 + 24\%)^x$

$y = 146 * (1 + 0.24)^x$

$y = 146 * (1.24)^x$

$y = 146(1.24)^x$

FOR 20 points

DochEvi [55]

Answer:

one tin of cheese $23

one tin of caramel $27

Step-by-step explanation:

let 'x' = cost of cheese tin

let 'y' = cost of caramel tin

10x + 8y = 446

22x + 11y = 803

i multiplied the first equation by -11 and the second by 8 to eliminate the 'y' terms

-110x - 88y = -4906

+ 176x + 88y = 6424

66x = 1518

x = 1518 / 66

x = 23

find 'y': 10(23) + 8y = 446

230 + 8y = 446

8y = 216

y = 27
