2x-3=y and x-y=-4 rearrange both so that y is by itself on one side...

y=2x-3 and y=x+4 subtract second equation from first and you get:

0=x-7 add 7 to both sides...

x=7, now use this value for x in either original equation to solve for y...

y=2(7)-3, y=11 so the solution is the point:

(7,11)

How many tacos could you buy with your money? If you had $20 dollars would you have enough money to buy a taco for 37 students o

8_murik_8 [283]

Answer:

You can buy 40 tacos

You have enough money

Step-by-step explanation:

Given

$Amount = \$20$

$Taco = 20$

$Unit\ Cost = \$0.50$ --- missing from the question

Required

Determine if you have enough amount

The number of Tacos that $20 can afford is calculated as:

$Tacos = \frac{Amount}{Unit\ Cost}$

So, we have:

$Tacos = \frac{20}{0.50}$

$Tacos = 40$

$40 > 37$ -- i.e. the number of Tacos will go round the 37 students

Hence, you have enough money

F(n) = 2• (-3)^n

Mashutka [201]

Answer:

$f(1)=-6$

$f(n)=f(n-1)(-3)$

Step-by-step explanation:

We are given that

$f(n)=2\cdot (-3)^n$

We have to complete the recursive formula of f(n).

Substitute n=1

$f(1)=2\cdot (-3)$

$f(1)=-6$

$f(2)=2\cdot (-3)^2=18$

$f(3)=2\cdot (-3)^3=-54$

$\frac{f(2)}{f(1)}=\frac{18}{-6}=-3$

$\frac{f(3)}{f(2)}=\frac{-54}{18}=-3$

It forms geometric sequence because the ratio of two consecutive terms are equal.

Therefore, the recursive formula

$f(n)=f(n-1)r$

$f(n)=f(n-1)(-3)$
