Lee spent $36 to purchase a combination of drinks, sandwiches, and chips for himself and his friends. A drink costs $2, a sandwi
valkas [14]

2x+4y+0.50z=36 represents the situation.

Step-by-step explanation:

Let,

Drinks = x

Sandwich = y

And,

Chips = z

Total amount on these items = $36

According to the statement;

x(cost\ of\ one\ drink)+y(cost\ of\ one\ sandwich)+z(cost\ of\ one\ chips)=\ Total\ amount\ spent\\2x+4y+0.50z=36

2x+4y+0.50z=36 represents the situation.

Which is the range of the function f(x) = (9)×?
Anna [14]

Using it's concept, it is found that the range of the function f(x) = 9^x is given by:

all real numbers greater than 0.

<h3>What is the range of a function?</h3>

It is the set that contains all possible output values for the function.

In this problem, the function is:

f(x) = 9^x

For <u>exponential functions without vertical shifts</u>, as is the case in this problem, the range is given by:

all real numbers greater than 0.

Drag each symbol and number to the correct location on the inequality. Not all symbols and numbers will be used. Sam initially i
galben [10]

Answer:

t \leq 18.67\ years

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=?\ years\\ P=\$4,500\\ A=\$7,020\\r=0.03

The inequality that represented this situation is

P(1+rt) \leq A

substitute the values and solve for t

4,500(1+0.03t) \leq 7,020

(0.03t) \leq (7,020/4,500)-1

t \leq [(7,020/4,500)-1]/0.03

t \leq 18.67\ years

3.2y-1.4y+y-0.6y=0.55
Kazeer [188]

Answer:

it is y=0.25

Step-by-step explanation:

because Step 1: Simplify both sides of the equation.

3.2y−1.4y+y−0.6y=0.55

3.2y+−1.4y+y+−0.6y=0.55

(3.2y+−1.4y+y+−0.6y)=0.55(Combine Like Terms)

2.2y=0.55

2.2y=0.55

Step 2: Divide both sides by 2.2.

2.2y

2.2

=

0.55

2.2
