how do you know if an equation has infinite solutions?
if the equation ends with a true statement, like 3=3, then you know it has sinfinite solutions. in this situation x=x
C:
3(2x+1)=6x+3
(multiply 3 by (2x+1))
6x+3=6x+3
(subtract 6x-3 from both sides)
0=0

Write the equation of the line that passes through the given point and is perpendicular to the given line. (0, 3); 3x − 4y = −8
Answers
Answer:
y = -4/3x + 3
Step-by-step explanation:
3x − 4y = −8
-4y = -3x - 8
y = 3/4x + 2
slope m = 3/4
perpendicular version of it is opposite inverse: -4/3
y-intercept through point (0, 3):
y = mx + b
3 = -4/3(0) + b
b = 3
Use the perpendicular slope with b from above to form new perpendicular equation of line:
y = mx + b
y = -4/3x + 3

Twenty-seven minus of a number (x) is not more than 36. What is the number?
A.
x > 42
B.
x ≥ -6
C.
x < 3
D.
x ≤ -6
Answers
Answer:
Step-by-step explanation:
Symbolically, we have: 27 - x ≤ 36.
We want to solve for x. To do this add x to both sides, obtaining:
27 ≤ x + 36.
Isolate x by subtracting 36 from both sides: -9 ≤ x or x ≥ -9

Caleb is making a soil mix that is 3 parts peat moss to 12 parts dirt. How much dirt should he use for every 1 cup of peat moss?
A He should add cup of dirt
B. He should add cup of dirt.
4
He should add 3 cups of dirt.
He should add 4 cups of dirt
Answers
Answer:
He should use 4 cups of dirt, Choice D
Step-by-step explanation:
Ratio of moss to dirt: 3:12 The ratio simplifies to 1:4
This shows that for every cup of moss, he should use 4 cups of dirt as the ratio says.
Answer:
4 cups of dirt
Step-by-step explanation:
since it is a ratio of 3:12, it can be put as a fraction of 3/12 which can be simplified to 1/4 thus is the ratio of 1:4 thus 1 part peat moss to 4 parts dirt and since the measurement is cup, you change parts to cups and you have your answer.
Sodium inc borrowed 280000in April 1the note requires interest at 12% and principal to be paid in one year, how much interest is recognized for the period from April 1 to December 31?
Answers
Given:
Principal = 280,000
Rate of interest = 12% per annum.
Time period is from April 1 to December 31.
To find:
The interest recognized for the period from April 1 to December 31.
Solution:
Time period from April 1 to December 31 is 9 months.
12 months = 1 year
1 month = [tex]\dfrac{1}{12}[/tex] year
9 month = [tex]9\times \dfrac{1}{12}[/tex] year
So,
[tex]Time=9\times \dfrac{1}{12}[/tex]
[tex]Time=\dfrac{9}{12}[/tex]
[tex]Time=0.75[/tex]
Formula for interest is
[tex]I=P\times r\times t[/tex]
where, P is principal, r is rate of interest and t is time.
[tex]I=280,000\times \dfrac{12}{100}\times 0.75[/tex]
[tex]I=25200[/tex]
Therefore, the the interest is 25,200.

While reviewing last months finances Oscar noticed that he had spent $200 on a wedding cake and deposited $500 and he just earned from selling books to a used bookstore down here again spent $127 to buy some new box which integer represents the change an Oscar savings
Answers
Answer:
an additional $173.
Step-by-step explanation:
The change in Oscar's savings is calculated by adding or subtracting all of the different transactions that have occurred. First, he spent $200 which would be a deduction and be subtracted from his initial balance. Next, he deposited $500 which is added to his balance, and lastly, he spent $127 which is subtracted from his balance. Like so...
-200 + 500 - 127 = $173
The final result is positive $173, this means that the change from his initial balance to his current savings balance is an additional $173.

VGeorge has $15. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money. Look at the numerical expression George used: 15 − 9 + 2.65 + 1.35 + 2(1.74) Can you help him determine why he does not have enough money?
Answers
Given:
George has $15.
He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money.
George used: 15 − 9 + 2.65 + 1.35 + 2(1.74)
To find:
Why he does not have enough money.
Solution:
Money her has = $15
All the expenses movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) must be subtracted from the money he has instead of adding these values.
George add the cost of pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each), therefore, he does not have enough money.
Remaining Amount = [tex]15-9-2.65-1.35-2(1.74)[/tex]
[tex]=15-9-2.65-1.35-3.48[/tex]
[tex]=15-16.48[/tex]
[tex]=-1.48[/tex]
Remaining money cannot be negative. Here expenses are more than the money he has. Therefore, he does not have enough money.
Answer:
it's not the best answer but i hope it helps
Step-by-step explanation:
George only has $15 dollars left. He spend $9.00 on a movie ticket and $2.65 on a pretzel. $9.00 - $2.65 would leave him with $6.35. Then, George decided to buy a drink for $1.35. George then wanted to get two veggie cups both for the price of $1.74, but if you subtract $1.35 - $1.74 thus would leave him with $0.39 and he wouldn't have enough money to buy both veggie cups. If George had $1.38 left then he would have enough to buy both veggie cups.

1 - a. addition
2 - c. constant
3. - b. coefficient

Step-by-step explanation:
+ is the universal sign for addition
11 is a number which is always constant
here w doesn't have a constant value and can be any number. hence it is a variable
the 2 in the 2w is a number which multiplies with the variable w. the value of 2w varies with the value of w. So here 2 is the coefficient of the w in 2w
i need help with 2: simplify algebraic expressions
Answers
Answer:
a). 11x²
b). 6x + 5y
c). -4x - 20
Step-by-step explanation:
a). 8x² + 3x²
When you collect the like terms (8 and 3 are the coefficients of x²) and add them together, you get 11x²
b). 3x - 5x + y + 4y + 8x
Start by placing the like terms next to each other.
3x - 5x + 8x + y + 4y
Then add/subtract
6x + 5y
c). -4(x + 7) + 8
First, you have to expand the expression and then simplify.
-4x - 28 + 8
-4x - 20

Answers
Answer:
No solution.
Step-by-step explanation:
Step 1: Write equation
-17(y - 2) = -17y + 64
Step 2: Solve for y
Distribute -17: -17y + 34 = -17y + 64Add 17y on both sides: 34 ≠ 64Here we see that we get y = no solution. You could also think about it as 2 parallel lines; they have the same slope but different y-intercepts so therefore there will be no intersection/no solution.
