how do you know how many solutions are possible for a system of equations
Answer:
Step-by-step explanation:
If the slopes are the same but the y-intercepts are different, the system has no solution.
If the slopes are different, the system has one solution.
If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
Answer:
Step-by-step explanation:
If you mean linear systems. If lines have a different slope there will be one solution. If they have the same slope (parallel) and a different y intercept there are zero solutions. If they have same slope and y intercept than they are the same line and have an infinite number of solutions.

Answer:
60
Step-by-step explanation:
A percentage is divided by 100 to get it's decimal form. So 400/100 = 4.0
Now you take the value given and multiply it by the percentage in decimal form.
So in this case.
15*4 = 60

How many grams of aluminum hydroxide are produced when 8 moles of aluminum sulfite react in excess sodium hydroxide ?
Answer:
Number of moles Aluminium sulfide
1 mole of sulfide contains 150 g
Therefore; 16.2/150
= 0.108 moles
The mole ratio of Al2S3 : Al(OH)3 is 1:2
Therefore; moles of Aluminium hydroxide will be;
= (0.108 × 2)
= 0.216 moles
But, 1 mole of Al(OH)3 contains 77 g
Therefore, the mass of aluminium hydroxide is
0.216 moles × 77
= 16.632 g

Solve for X:
5x - 14 = 8x + 4
a X = -6
b
X = 10/3
c
X = 6
d
X = -18/13
Answer:
a) x = -6
Step-by-step explanation:
5x - 14 = 8x + 4
-14 = 3x + 4
-18 = 3x
x = -6
Answer:
A) 5 (-6) - 14 = 8 (-6) + 4
- 30 - 14 = - 48 + 4
- 44 = - 44
Step-by-step explanation:
La respuesta correcta es la A, ya que x = - 6
Which inequality is represented by this graph? 0 - 345> x O 0 -34.5 0 -355 cx
Answer:
Step-by-step explanation:
If x is the white dot on the graph:
From what it looks like, x is right between -35 and -34 x (which is -35.5).
If that is the case then none of the answers are correct since -35.5 is equal or less than x. (the sign looks like this: "[tex]\leq[/tex]" )
But if you have to choose one of the answers then number 4 (-35.5 < x) would be closest.
Amy and three of her friends went to lunch. The total bill was $54.00. If they wanted to leave a 20% tip how
much more is added tot he bill?
If the girls split the bill evenly, how much does Amy pay?
Answer:
$16.20
Step-by-step explanation:
Bill: $54.00
Tip: 20%
People: 4
To figure out 10% of the bill, you need to move the decimal point over to the left one place: $5.40
10%: $5.40
5.40 times 2 = $10.80
54.00 + 10.80 = 64.80
Grand Total= $64.80
Since there are 4 people, we need to divide by 4:
64.80 divided by 4 = $16.20
What central tendency means to find the number that occurs most often?
Median
Mean
Mode
Range
Answer:The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. For data from skewed distributions, the median is better than the mean because it isn't influenced by extremely large values.

Which conic section is represented by the following equation? 9x^2 – 5x – 3y^2 – 2y + 4 = 0
Answer:
D. Hyperbola
Step-by-step explanation:
I put B but it was wrong
D is the right answer
The given equation is represent a ''Hyperbola''.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ 9x² - 5x - 3y² - 2y + 4 = 0
Now, We know that;
The standard form of the equation is,
⇒ ax² + by² + 2gx + 2fy + 2hxy + c = 0
For Hyperbola, The condition is,
⇒ h² > ab
For Ellipse , The condition is,
⇒ h² < ab
Here, We have;
⇒ h = 0
⇒ a = 9
⇒ b = - 3
⇒ ab = 9 x - 3 = - 27
⇒ h = 0
Hence, We get;
⇒ 0 > - 27
⇒ h² > ab
Thus, This equation is represent a ''Hyperbola''.

Michael drove from home to work at an average speed of 50 mph. His return trip home took 30 minutes longer because he could only drive at 40 mph. Find the distance from his home to his work. A. [3 pts) Define variables to represent the unknowns and setup the necessary equations to answer the question. B. [4 pts) Algebraically solve the equation you created and express your final answer using a complete sentence and appropriate units. (You will not receive full credit if a trial and error method is used in place of an algebraic method.)
Answer:
100 miles
Step-by-step explanation:
Given :
To work :
speed = 50mph
Let time taken = x
From work :
speed = 40mph
30 minutes = 30/60 = 0.5
Time taken = x + 0.5
Distance from home to work :
Distance = speed * time
To work distance = from work distance
This can be algebraically expressed as :
50 * x = 40(x + 0.5)
50x = 40x + 20
50x - 40x = 20
10x = 20
x = 20/10
x = 2
Hence,
Distance = 50 * 2 = 100
The the distance from home to work = 100 miles
The distance from Michael home to work is 100 miles
SpeedSpeed is the ratio of the total distance travelled to the total time taken. It is given by:
Speed = distance / time
Let d represent the distance from Michael home to work. Hence:
50 = d/tt = d / 50He took 30 minutes (0.5 hours) longer when driving at 40 mph, hence:
40 = d/(t + 0.5)t = (d - 20)/40d/50 = (d - 20) / 40
40d = 50d - 1000
10d = 1000
d = 100 miles
The distance from Michael home to work is 100 miles
