A system of 3 linear equations in 3 variables is consistent and independent. How many solutions to the system exist
Answer:
One solution
Step-by-step explanation:
By definition:
A system of linear equations is classified according to the number of solutions such as:
* Consistent: If the system has at least one solution.
* Inconsistent: If the system has no solution
Then, the systems of consistent linear equations are classified as:
* Independent: If the system has only one solution
* Dependents: If the system has endless solutions.
Thus. A consistent and independent system of equations has only one solution
“The height of an arrow” NEED HELP WITH THIS QUESTION ASAP!
Answer:
a) t = 0.54 seconds
b) t = 8 seconds
Step-by-step explanation:
Given in the question the equation
h = 40t - 5t²
where h is height in meters
t is time in seconds
Time it took to reach 20 meters
20 = 40t - 5t²
-5t² + 40t - 20 = 0
by using quadratic formula for factorisation
t = (-b± √(b)² - 4(a)(c) ) / 2(a)t = 0.54 (upward motion)
or
t = 7.46 (downward motion)
b) Time it took to reach the ground
at ground h = 0
So,
0 = 40t - 5t²
t(40 - 5t ) = 0
t = 0 (at starting point)
or
40 -5t = 0
5t = 40
t = 40 /5
t = 8 seconds
{-3 - y = -12
{ x - 3y = 14
Answer:

x = 59
Step-by-step explanation:
move the -3 over to the -12 side. then divide by -1 on both sides getting:
{ y = 15
{ x- 3y = 14
change the y in the second equation to get:
x - 3 (15) = 14
x - 45 = 14

What is the angles listed from descending order?
Answer:
RQ, RP, PQ
Step-by-step explanation:
The side opposite the largest angle is the largest side
Angle P at 105 is the largest angle so RQ is the largest side
Next largest angle is Q at 75, so RP is opposite it
The smallest angle is R, so the smallest side is opposite it, which is PQ
From largest to smallest
RQ, RP, PQ
Answer:
The correct answer is option 2
RQ > PQ > RP
Step-by-step explanation:
From the figure we can see that, a triangle PQR.
Three angles are given.
The angles are, <P = 105°, <R = 40° and <Q = 35°
To find the order of sides
We know that, the side opposite to the largest angle is the largest side, So we can write the three sides are in ascending order,
RQ > PQ > RP
Therefore the correct answer is option 2

Harry's uncle gave him $62 to spend on basketball equipment. He bought 2 jerseys that cost $4 each, a basketball that cost $19, and a pair of shorts that cost $5. How much money does Harry have left?
Final answer:
Harry spent a total of $32 on basketball equipment, and since he started with $62, he has $30 left.
Explanation:
To calculate how much money Harry has left after purchasing basketball equipment, we need to add up the total cost of the items he bought and subtract that from the amount of money he was initially given. Harry bought 2 jerseys at $4 each, 1 basketball at $19, and a pair of shorts at $5.
Cost of 2 jerseys: 2 × $4 = $8
Cost of basketball: $19
Cost of shorts: $5
Now, we'll sum up the costs of these items to find the total expenses.
Total expenses = $8 + $19 + $5 = $32
Next, we'll find out how much money Harry has left after these purchases:
Money left = Initial amount - Total expenses
Money left = $62 - $32 = $30
So, Harry has $30 left after buying the basketball equipment.

20 cannot go into 16 a whole number of times, but in terms of decimal division, 20 goes into 16 exactly 0.8 times.
The question asks how many times 20 can go into 16. In mathematical terms, this is asking for the result of dividing 16 by 20. Since 20 is larger than 16, 20 cannot go into 16 a whole number of times. However, if we are considering division in terms of fractions or decimals, 20 goes into 16 exactly 0.8 times because 16 divided by 20 equals 0.8.

A quadratic function has these characteristics:
x = 1 is the equation for the axis of symmetry.
x = –1 is an x-intercept.
y = –4 is the minimum value.
Determine the y-intercept of this parabola.
Explain your thought process.
Answer:
The y-intercept would be between 0 and -4 likely about -3.
Step-by-step explanation:
The y-intercept would be between 0 and -4 likely about -3.
Since the parabola has an axis of symmetry at x = 1 and a minimum of y = -4 then the vertex is (1,-4).
It has an x-intercept at x = -1 or (-1,0). This means from the vertex up to the x-intercept the function has to cross through the y-axis. This makes the y-intercept between 0 and -4 and likely at -3.
The y-intercept of the quadratic function given above is found to be at y = -3. This conclusion is reached by analyzing the vertex, its symmetry, and x-intercepts of the function, and applying these properties in the standard form of a quadratic function.
Explanation:The subject of this question is the properties of a quadratic function in mathematics. The given characteristics provide us with enough information to determine the y-intercept of the function. Let's analyze the information.
Since the axis of symmetry is 'x = 1', we know that the vertex of the parabola is at (1, y). Also, because it has a minimum value of 'y = -4', we know the y-coordinate of the vertex is -4. Therefore, the vertex of the parabola is at (1, -4).
An x-intercept at 'x = -1' means that (-1, 0) is a point on the parabola. From the nature of the symmetry of parabolas, we know that if there is a point (a, 0) on the parabola, there will also be a point on the other side of the axis of symmetry at (2h-a, 0), where 'h' is the x-coordinate of the vertex. So, we can calculate the other x-intercept as (2*1 - (-1), 0), which gives us (3, 0). Thus, a point on the parabola is also (3, 0).
Equipped with the vertex (1, -4) and a point on the parabola (3,0), we can use the form of a quadratic function y = a(x-h)² + k to determine the quadratic function. Substituting coordinates of the vertex into the formula for h and k, and the coordinates of the point into the formula for x and y, we get 0 = a(3-1)² + (-4). From that, we can solve for 'a', which equals 1.
So, our quadratic function is y = (x-1)² - 4. To find the y-intercept (the point where the function crosses the y-axis, where x=0), we substitute x=0 into our function, which yields y = (0-1)² - 4 = -3.
The y-intercept of the parabola is at y = -3.

Sonji paid $25.00 for two scarves, which were different prices. When she got home she could not find the receipt. She
remembered that one scarf cost $3 more than the other. What was the price of the more expensive scarf?
Answer:
$14
Step-by-step explanation:
Sony paid for two scarves = $ 25
We are given that one scarf cost $3 more than the other
Let the cost of one scarf be x
So, cost of another scarf = x+3
Since the total cost is $25
So, [tex]x+x+3=25[/tex]
[tex]2x+3=25[/tex]
[tex]2x=22[/tex]
[tex]x=\frac{22}{2}[/tex]
[tex]x=11[/tex]
So, cost of one scarf = $11
Cost of another scarf = x+3=11+3=14
Hence the cost of the expensive scarf is $14

The side of a square measures 3mn2. What is the area of the square if m = 4 and n = -2?
The area of the square is 2304 square units.
How to calculate the area of the square from theinformation mentioned in the question ?Given the side of the square measures [tex]3mn^{2}[/tex]
We have to find the area of the square when m = 4 and n = -2
Putting the value of m and n in the expression to get the value of side of the square -
Side = [tex]3mn^{2}[/tex] = [tex]3*4*(-2)^{2}[/tex] = [tex]48[/tex]
Thus the length side of the square is 48 units.
As the square has all of its 4 sides equal, thus the area of the square is = side*side .
∴ Area of the given square = side*side = 48*48 = 2304 square units.

x-y=5

Is the answer H, I, J, or K
H. infinitely many I. no solution J. (0,5) K. (5,0)
Answer:
I would be our answer.
Step-by-step explanation:
So we need to solve both.
x-y=5 = 5.
And we also need to solve -x+y=5.
Let's regroup them.
[tex]y-x=5[/tex]
Now we needt to subtract y from both sides.
[tex]-x = 5 -y[/tex]
Now let's multiply both sides by -1.
[tex]x = -5 + y[/tex]
Then we finally get
x = y - 5
Our final answer is I, there is no solution for this problem. Yes, they both equal 5 but do not fit any of the answers.
