What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have the Equation:
6x² + 5x - 4 = 0
Solving the Quadratic equation
6x² + 5x - 4 = 0
6x² -3x + 8x - 4 = 0
3x( x- 2) +4 (x-2)= 0
(3x + 4) (x-2) = 0
3x +4 = 0 or x-2 = 0
x = -4/3 or x= 2

Harry liked to collect old movies. On 4 different days, he bought 2 movies. On 2 other days, he bought 3 movies each day. After that he sold 2 sets of 2 movies. He figured out how many he had total, and then he divided that total into 2 groups to put onto his shelves. How many did he put on each shelf? Choose the expression that best matches this situation.
Answer:
Harry put 5 movies on each shelf.
Step-by-step explanation:
The information provided is:
On 4 different days, he bought 2 movies.On 2 other days, he bought 3 movies each day. After that he sold 2 sets of 2 movies.He divided the remaining into 2 groups to put onto his shelves.So, first Harry bought 2 movies on four different days.
That is, a total of 8 movies.
Then, he bought 3 movies on two other days.
That is, a total of 6 movies.
So, in total Harry bought 14 movies.
Now, he sold 2 sets of 2 movies.
That is, he sold 4 movies.
He has 14 - 4 = 10 remaining movies with him.
It is provided that he divided remaining movies into 2 groups to put onto his shelves.
So, he put 10/2 = 5 movies on each shelf.

Which statement best describes the graph of 2x−5y=−25 and the graph of y=5/2x+5?
Identify the inequality for the given graph.
Answer:
We. can see there's a black point at -3.7 and an arrow going to the left.
As the arrow goes to the left, it must be less than -3.7 or less than or equal to -3.7, now, we will need to see the colour of the point to know which it is.
As there is a black point, -3.7 is also contained in this range...
What does that mean? That means it will be less than or equal to -3.7
So we know the correct option is a) less than or equal to -3.7, what we could write as ([tex]-\infty,-3.7[/tex]].

Whitney made 7 1/2 quarts of hot chocolate. Each mug holds 5/6 of a quart. How many mugs
will Whitney be able to fill?
Write your answer as a fraction or as a whole or mixed number.
Answer:
15
Step-by-step explanation:
The total of hot choclate made by Whitney = 7 1/2 quarts.
= 7 (2) + 1 15
----------- = ---

26/90 = n/360
What is N?
Answer:104
Step-by-step explanation:
Answer:
n = 104
Step-by-step explanation:
26/90 = n/360
Using cross products
26 * 360 = 90 (n)
Divide each side by 90
26 * 360/90 = 90 (n)/90
104 = N
Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowance of $40 per week for gas. She knows her weekly earnings can be shown using the following expression: 7.50h + 0.20s + 40 Part A: Identify a coefficient, a variable, and a constant in this expression. (3 points) Part B: If Corinne works for 25 hours and sells $300 in magazines, how much does she earn for the week? Show your work to receive full credit. (4 points) Part C: If Corinne gets a raise and begins earning $9 per hour, would the coefficient, variable, or constant in the equation change? Why?
Part A
The coefficient would be the number that is with a variable. The coefficient of 7.50h is 7.50. The variable is h, variables can be a letter or symbol that stands for something in a equation. For this question, h stands for the number of hours Corinne works. The constant is the number that is alone in the equation. That doesn't have a variable with it. In this equation the constant would be the number 40.
Part B
To solve this I will plug in 25 into "h" in and 300 for "s" in the equation 7.50h + 0.20s + 40 and then solve it.
25 × 7.50 = $187.5.
0.20 × 300 = $60
Total: $187.50 + $60 = $247.50 + $40 = $287.50
Part C
If Corrine gets a raise and earns $9 an hour the coefficient would change. It would be 9h instead of 7.50h.
The Yellow Cab Company charges just $0.25 a mile, but it costs $5 to get in the cab. Express
Cab charges no fee to get in the cab, but $1.50 a mile for the ride.
a) If you are going 7 miles, which cab company should you call?
b)
If you are going 3 miles, which cab company should you call?
c)
For what length of drive is the cost equal?
Answer:
For 7 miles call they Yellow Cab and for 3 miles call Express Cab
In 4 miles it cost $6.00 for both
Step-by-step explanation:
Express Cab= $4.50 for 3 miles, and for 7 miles it cost $10.50
Yellow Cab = $5.75 for 3 miles, and for 7 miles it cost $6.75
add 1.50 to 4.50 and is 6 dollars in 4 miles and add 0.25 to 5.75 and it also makes it 4 miles
2x3 + x2 + 7x - 6)-(- 2x + 10x + 10x+9)

1/4a + 1/3a + 8 = 22 what would be the steps to solve this
Answer:
Step-by-step explanation:
first i would combine like terms so 1/4a + 1/3a is equal to 7/12 then the equation would be 7/12a+8=22 simplify the isolate the variable so i think it A=24
Answer:
Hey there!
Step-by-step explanation:
Equation: 1/4a + 1/a + 8 = 22
(The answer is 24)
(You have to do 3 steps in order to solve this question! The steps are below!)
~1. First you have to simplify both sides of the equation.
=> (1/4a + 1/3a) + (8) = 22
=> 7/12a + 8 = 22
~2. Next, subtract 8 from both of the sides.
After you do that you will get, 14
7/12a=14
~3. Lastly, you just multiply both sides by 12/7.
(12/7) x (7/12a)
(12/7) x (14)
~Therefore, A would equal to 24.
A=24
~Hope this helps!
~Good luck! :)

Solve graphically 6x-3y+10=0 and 2x -y +9 =0
Answer:
Step-by-step explanation:
6x-3y+10=0 ⇒-3y=-6y-10 ⇒ y=-6x/-3 -10/-3⇒ y=2x+10/3
2x -y +9 =0 ⇒ -y=-2x-9 ⇒y=2x+9
y=2x+10/3y=2x+9Roger is x centimeters tall and Olivia is y centimeters tall. Their oldest sister, Isabella, is 25 centimeters shorter than the double of the sum of Roger and Olivia’s height. Write an expression for Isabella’s height
Answer: 2(x+y)-25
Step-by-step explanation:
First, we need to show the sum of Roger and Olivia's heights. If Roger is x and Olivia is y, the sum is x+y
Next, we need to double that. To double something we multiply it by 2. Since we need double the expression we found above, we put it in parentheses. So the doubled sum is shown as 2(x+y)
Finally, we need to show that Isabella is 25 centimeters shorter than the doubled sum. To do that, subtract 25.
The final expression for Isabella's height is 2(x+y)-25

A president and vice-president for a student organization are chosen from eleven people. How many different president/vice-president combinations are possible?
Answer:
110 combinations.
Step-by-step explanation:
We are going to be choosing without replacement.
Out of 11 people, we can choose one president, but after choosing, we would be left out with 10 people to choose a vice president from.
To calculate the possible combinations of president and vice-president, we multiply 11 by 10
11 x 10
= 110
Therefore we have 110 vice-president/president possible combinations.
