Evaluate the algebraic expressions, and put their values in order from least (1) to greatest (4), for a = 2 and b = 5 1. 50 − b2 + a 2. a2(5 − b) 3. b2 − 10 4. a(b − 3)

ill give brainiest to first answer

0

4

15

27

Step-by-step explanation:

a) The first expression is

When a=2 and b=5, we get

b) The second expression is

We substitute a=2 and b=5;

c) The next expression is

We substitute b=5 to get:

d) The fourth expression is

When a=2 and b=5

We know that:

0<4<15<27

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
