3. Rewrite the expression as simply as you can:
3x + 11y - 2x - 4y
Answer:
x+7y
Step-by-step explanation:
First off, lets split the question into both x and y.
3x - 2x for the x
11y - 4y for the y
You can solve both of them to get x + 7y
3x - 2x = x
11y - 4y = 7y
Then, add them back up and get x + 7y
Answer:
x+7y
Step-by-step explanation:
3x + 11y -2x - 4y
(3x) + (11y) + (-2x) + (-4y)
(3x) + (-2x) = x
(11y) + (-4y) = 7y
3x + 11y -2x - 4y = x + 7y
PLEASE HELP ASAP!! WILL GIVE BRAINLIEST
Step-by-step explanation:
12) y = 4 + 7x
x = 3,-1
y = 4 + 7(3) = 25
13) y = x - 11
x = 72,
y = 72 - 11 = 61
14) y = 6x - 5
y = 6(-4) - 5 = -29
y = -11 (x = -1)
y = -5 (x = 0)
y = 13 (x = 3)
15) y = x + 1, each relation is a function
16) An = 22 + (n-1)11

Mason inspects 73.5 phones each day. He must inspect no fewer than 1,470 phones each month. How many days will Mason need to work to reach his goal by the end of the month.
Answer:
20 days
Step-by-step explanation:
We have 31 days in one month
Mason must have inspected 1470 after 31 days
He inspects 73.5 phones per day. Hence,
73.5 phones =>1 days
1470 phones =>
1470 ÷ 73.5 => 20 days
Hence, Mason will need 20 days to reach his goal.

4.) Are imperfect square roots rational or irrational?
Answer:
Irrational
Step-by-step explanation:
Answer:
Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).

Answer:
no solutions
Step-by-step explanation:
6(x+1)=-2(3x+9)
distribute both sides first then you get:

B. 13
C. 18
D. 22
Answer:
B. 13
Step-by-step explanation:
5 + 4 × 2 = 13
The correct option is (B).
What is PEMDAS rule?PEMDAS: Order of Operations
P: Solve the calculation or equation which are present in the parentheses or brackets like small brackets( ), curly brackets{ } or big brackets[ ]. Priority is given to brackets first.
E: Exponential expressions should be calculated first before the operations of multiplication, division, addition and subtraction.
MD: Then perform multiplication or division from left to right, whichever comes first in the equation.
AS: At last, perform addition or subtraction whichever comes first while moving from left to right.
Given expression,
5 + 4 × 2
According to order of operations:
Solving multiplication operation:
5 + 8
Now solving addition operation
= 13
Hence, after applying order of operations, the value of expression is 13.

9. What four consecutive integers have a sum of -34?
Given,
The four numbers are consecutive
The numbers are
x
x + 1
x + 2
x + 3
Sum = -34
x + (x + 1) + (x + 2) + (x + 3) = -34
x + x + 1 + x + 2 + x + 3 = -34
(x + x + x) + (1 + 2 + 3) = -34
3x + 6 = -34
3x = -34 - 6
3x = -40
x = -40/3
The fox population in a certain region has a continuous growth rate of 6 percent per year. It is estimated that the population in the year 2000 was 19100.
(a) Find a function that models the population t years after 2000(t=0 for 2000).
Hint: Use an exponential function with base e.
Your answer is P(t)=
(b) Use the function from part (a) to estimate the fox population in the year 2008.
Your answer is (the answer must be an integer)
Answer
a)
[tex] P(t) = 19100. e^{0.06t} [/tex]
b) P(8) =30866
Step-by-step explanation
Use formula:
[tex] P(t) = P. e^{rt} [/tex]
a)
Here, P = 19100
r = 6% = 0.06
[tex] P(t) = 19100. e^{0.06t} [/tex]
b) t = 2008 - 2000 = 8
[tex] P(8) = 19100. e^{0.06\times 8} [/tex]
[tex] P(8) = 19100. e^{0.48} [/tex]
[tex] P(8) = 19100\times 1.616\\\\
P(8) = 30,865.6\\\\P(8) \approx 30,866[/tex]
