$y=a^x\\\\if\ a>1,\ then\ the\ graph\ is\ increase\ and\ has\ positives\ values\ of\ y\\\\if\ a\in(0,\ 1),\ then\ the\ graph\ is\ decrease\ and\ has\ positives\ values\ of\ y\\\\y=-a^x\\\\if\ a\in(0,\ 1),\ then\ the\ graph\ is\ increase\ and\ has\ negatives\ values\ of\ y\\\\if\ a>1,\ then\ the\ graph\ is\ decrease\ and\ has\ negatives\ values\ of\ y$

$f(x)+n\to translate\ the\ graph\ n\ units\ up\\\\f(x)-n\to translate\ the\ graph\ n\ units\ down\\\\$

$\text{We have the decrease graph with negatives values of y}.\\\\\text{Therefore your answer is}:\ \boxed{y=-4^x+3}$

Joanne cannot decide which of two washing machines to buy. The selling price of each is $720. The first is marked down by 50%.

Archy [21]

Answer:

More expensive

Step-by-step explanation:

FIRST WASHING MACHINE PRICE - $360

SECOND WASHING MACHINE PRICE - MUST NOT BE CHEAPER

$720 x 30% = $216

The additional percentage must make the washing machine more expensive than the first one.

Write the ratio as a fraction in the simplest form 25 to 45

svp [43]

25 to 45 can also be written as 25/45
Both numbers are divisible (can be divided by) 5
25 divided by 5 = 5
45 divided by 5 = 9

So 25/45 = 5/9

They are equivalent fractions because they’ve been divided by the same, shared number
