TE Irene has a collection of 32 dolls that have either blue eyes or green eyes. She has 14 more green-eyed dolls than blue-eyed dolls. How many dolls of each type does Irene have? Let x represent the number of green-eyed dolls. Let y represent the number of blue-eyed dolls.
The formula
x + y = 32
Find our X value
y + 14 = x
Sub for x
(y + 14) + y = 32
Remove Parathesis
y + 14 + y = 32
Add
2y + 14 = 32
Subtract
2y = 18
Divide
y = 9
Sub for y
x + 9 = 32
Subtract
x = 23
Double Check:
9 + 14 = 23
23 + 9 = 32

Grapes are 2.55 per pound and on two separate occasions Dana went to the store to
buy grapes. The first time she went to the store she bought 3.25 pounds of grapes
and during the second visit to the store she purchase 1.25 pounds of grapes.
Rounded to the nearest cent, what is the total amount that Dana paid for the grapes?
$7.25
$12.35
$11.48
$7.05
Answer: $11.48
Step-by-step explanation:
First of all, you have to multiply 3.25 by 2.55 because the grapes are 2.55 per pound. That makes 8.2875 for the first occasion. Next, you have to multiply 1.25 by 2.55 for the second occasion. That makes 3.1875. You then have to add 8.2875 and 3.1875. You get 11.47500, and that rounded to the nearest cent is $11.48.

Antonio wants to examine the sales in a restaurant during a period of time from 2 hours before to 2 hours after the peak dinner time and graph his results. If the peak dinner time is considered to be at 6 p.m., what would be the domain for the graph Antonio is creating?
Using function concepts, it is found that the domain of the graph Antonio is creating would be: [tex]4 \leq x \leq 8[/tex]
The domain of a function is the set that contains all possible input values.In this problem, the inputs are the time, between 2 hours before and 2 hours after the peak time of 6 pm, hence, it is given by: [tex]4 \leq x \leq 8[/tex]

is a persons weight a function of their height why
Answer:
nope
Step-by-step explanation:
it's not because let's say for example we have two students who weigh 130 pounds on of them could just be very wide but the other one could be really tall which results in his weight.
Although in some cases if both people are athletes and you say that they are not wide then it could give you a not exact estimate of how tall he is.

What is the value of 3^2x+1, if 3^x=a
Guys HELPPPPP
Step-by-step explanation:
We use the power rule a^(x+y) = a^x * a^y:
3^(2x+1) = 3^(2x) * 3
We can re-write 3^(2x) as (3^x)^2, and we know that 3^x = a, so:
3a^2 is the final answer. There is not exact value, it's all just about re-writing.
[tex]3a^2 [/tex] is a required answer.
Answer:
solution given:
[tex]3^{2x+1}=? [/tex]
if [tex] 3^x=a[/tex]
By using power rule, we can write
[tex]3^{2x+1}[/tex] as
[tex]3^{2x+1}=(3^x)^2*3^1 [/tex]
[tex]a^2*3=3a^2 [/tex]

Solve the inequality below for t.
3 - 13t >/= -9 - 9t
Answer:
T is =/> 3
Step-by-step explanation:
Add 9t to both sides, 3-4t>/= -9 . Subtract 3 from both sides. -4t>/=-12
divide 12 by 4 for 3. Because 3 results in equality between both sides, it is equal, however if t is greater than 3, the lefthand side becomes greater than the right.
