Answer: yes

Step-by-step explanation: In this problem, we are asked to determine if the relation shown here is a function. The easiest way to determine if a relation is a function is by looking at the x-coordinates. Notice that none of the coordinates repeat so this relation is a function.

What is -11 + 3(b + 5) = 7

IRISSAK [1]

Answer:

b=1

Step-by-step explanation:

$\sf -11 + 3(b + 5) = 7$

First, let's regroup, terms,

$\sf 3(b+5)-11=7$

Add 11 to both sides,

$\sf 3(b+5)=7+11$

Simplify, 7+11 = 18,

$\sf 3(b+5)=18$

Now, divide both sides by 3,

$\sf b+5=\frac{18}{3}$

Simplify, 18/3 = 6,

$\sf b+5=6$

Subtract 5 from both sides,

$\sf b=6-5$

$\sf b=1$

Hope it helps! :)

Your bank balance is $102.35 and you've just made purchases for $20, $33.33, and $52.80. You then make deposits of $25 and $24.7

Dafna11 [192]

It is A because when you add the amount of your purchases and you subtract it from 102.35. You get a negative number. Then you add that negative number to 25 and 24.75.
