What is the definition of no solution?
Answer:
No solution would mean that there is no answer to the equation.
Step-by-step explanation:
It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true.
There is no answer to that problem. There is either a critical error in the problem, or it's just impossible to calculate. For example, x/0 is literally nothing. You can't solve it.

Step-by-step explanation:
Ron is saving money for college. Each month he deposits 10% of his net income plus
an additional $50 into a savings account. His net income, after taxes have been taken
out, is 80% of his gross income. Find the amount that Ron saves a month when his
gross income is $2400.
Answer:
$242
Step-by-step explanation:
His Gross income a month is $2400.
Now, we are told that his net income, after taxes have been taken out, is 80% of his gross income.
Thus;
Net income a month = 80% × 2400 = $1920
Now, Each month he deposits 10% of his net income plus an additional $50 into a savings account.
This means amount saved each month is = (10% × 1920) + 50 = 192 + 50 = $242

I just took a science test and got a 80% on the test. CBA's are 50% of our grade and I had a 98% in science class. How much will my grade drop?, what will my new grade be?
Answer:
89%
Step-by-step explanation:
Answer:
Grade drops 9 percentage points.
New overall grade is 89%
Step-by-step explanation:
The test with a score of 80% accounts for 50% of the grade.
The current average of 98% accounts for the other 50% of the grade.
50% of 80% + 50% of 98% =
= 40% + 49%
= 89%
The new overall grade is 89%.
Since the previous overall grade, before the test, was 98%,
and 98% - 89% = 9%, then
the new grade is 9 percentage points lower than the previous overall grade.

Given f(x) = -7x + 9, what is the slope and y-intercept?
Answer:
7x is the slope,9 is the y-intercept
Step-by-step explanation:

3(x+-10)=5(2x+8) Honestly I hate math lol.
Answer:
- 10
Step-by-step explanation:
Step 1:
3 ( x - 10 ) = 5 ( 2x + 8 ) Equation
Step 2:
3x - 30 = 10x + 40 Multiply
Step 3:
- 30 = 7x + 40 Subtract 3x on both sides
Step 4:
- 70 = 7x Subtract 40 on both sides
Step 5:
x = - 70 ÷ 7 Divide
Answer:
x = - 10

Answer: your independent variable will be the group that receives the placebo. the dependent variable would be the group that received serum B, and your experimental group are the agents from both groups. I say that because both groups received the experimental serum, whereas the first group got a placebo. not sure if your teacher only wants one answer for each questions, but this is what I believe to be correct.
Step-by-step explanation:
Jada is making lemonade for a get-together with her friends. She expects a total of 5 to 8 people to be there (including herself). She plans to prepare 2 cups of lemonade for each person. The lemonade recipe calls for 4 scoops of lemonade powder for each quart of water. Each quart is equivalent to 4 cups. Let represent the number of people at the get-together, the number of cups of water, the number of scoops of lemonade powder. Select all the mathematical statements that represent the quantities and constraints in the situation.
Answer: B,C,D,F
Step-by-step explanation:
All the correct mathematical statements that represent the quantities and constraints in the given situation are;
Option B; 5 ≤ n ≤ 8
Option C; c = 2n
Option D; l = c
Option F; 10 ≤ l ≤ 16
We are told that;
n = the number of people
c = the number of cups
l = the number of scoops of lemonade powder.
We are told that number of people is a total of between 5 to 8 people. Thus, the inequality to represent this is; 5 ≤ n ≤ 8We are told that she wants to prepare 2 cups of lemonade for each person. This means when n = 1, c = 2 ; when n = 2, c = 4. Thus, this can be expressed as; c = 2nWe are told that the lemonade recipe calls for 4 scoops of lemonade powder for each quart of water. That means 4 lemonade powder scoops = 4 cups. This can be expressed as; 4l = 4c. This can be simplified to; l = c
Since she is expecting between 5 to 8 people including herself. 2 lemonade scoops per person means;
the least amount of lemonade = 5 × 2 = 10
the maximum lemonade = 8 × 2 = 16
This can be written in inequality form as;
10 ≤ l ≤ 16
The only options that correspond with all the inequalities gotten above are; Options B, C, D, F.

A=Pe
rt
P=7500\hspace{35px}r=0.015\hspace{35px}t=8

A=7500e
0.015(8)
Plug in
A=7500e^{0.12}
A=7500e
