Answers
Answer:
1) D: All of the above.
2) A: No solution
3) B: One solution
Step-by-step explanation:
1. The systems of linear equations can be solved through the following methods:Graphing method: Using the slope and y-intercepts of each equation to plot points and graph the lines to see whether the given system has a point of intersection as a solution.
Elimination method: this involves either adding (when the coefficients have opposite signs) or subtracting (when the coefficients have the same sign).
Substitution method: involves solving for one of the variables of either equations, and substituting the values of that expression into the other linear equation in the system.
Therefore, the correct answer is Option D: All of the above.
2. Graph of Parallel Lines:Given the graph of parallel lines, which means that they will never have a point of intersection. Therefore, the given systems of linear equations have no solution. Therefore, the correct answer is Option A: No solution.
3. Graph of Two Intersecting linesGiven the graph of two non-perpendicular intersecting lines, it means that they have one point of intersection that represents the solution to the given system.
Therefore, the correct answer is Option B: One solution.

a car covered a certain distance at the speed of 24mph. while returning, the car covered he same distance witht eh spped of 16mph. what has his average speed?
Answers
Answer:
19.2
Step-by-step explanation:
You have to trust me, this answer is correct. But here's my solution:
With the formula
Distance=Speed multiplied by Time, we can infer that Speed=Distance/Time.
But we only have one variable (Speed) in the two we need (Speed and Time), we have to pretend we have both variables. You can put the time as 1 hour because that's the most basic unit. Note that this strategy will also work with 2 hours, 3 hours, or any measure of time.
So now for distance, let's see how fast a car can travel 24 miles. When going at 24 mph, then it'll take 1 hour. With 16 mph, then it'll take 1 hour and 30 minutes, so 1.5 or 3/2 hours.
Now we have the distance, which is 2 times 24 (Because the 24 mph and 16 mph both traveled 24 miles), equaling 48, and time, which is 1 hour plus 1.5 hours, which is 2.5 hours.
Now we use the formula Speed=Distance/Time, with 48/2.5=19 1/5 or 19.2

Josef and Mai divided some stamps between themselves. Josef got 60% of the stamps. If Josef received 500 more stamps than Mai, how many stamps did Josef receive?
Answers
The number of stamps Josef received out of the total stamps of 2,500 is 1,500 stamps
let
x = total number of stamps
Josef share = 60% of x
= 0.60 × x
= 0.60x
Mai = 40% of x
= 0.40x
Josef = 0.40x + 500
Total = Josef + Mai
x = (0.40 + 500) + 0.40x
x = 0.40x + 500 + 0.40x
x = 0.80x + 500
x - 0.80x = 500
0.20x = 500
x = 500/0.20
x = 2,500
Josef share = 60% of x
= 60/100 × 2,500
= 0.60 × 2,500
= 1,500 stamps
Therefore, the total number of stamps shared between Josef and Mai is 2,500

Identify the graph for the point C(−2, −1, 2) in three-dimensional space.
Answers
Answer:
the topmost one maybe?
Step-by-step explanation:
I'm guessing since X & Y are negative, (it's written X,Y,Z, right?)
The point would be reducing on the X&Y axes, an since Z is positive, it would increase on the Z axis
The point C( -2,-1, 2) is represented by option 4 in the three dimensional space
What does the coordinates of a point mean in a three dimensional space?Let (x, y , z) be any point in the three dimension then x represents x-coordinate, y represent y-coordinate and z represent z- coordinate
The point C( -2, -1. 2) represent point with x = -2 , y = -1 and z = 2
(-2,-1) is point with x= -2 and y = -1 represent is marked in the the x y plane in fourth quadrant and z =2 means that this (-2,-1 ) is taken 2 units up in the perpendicular direction of positive z- axis as shown in the attached figure.

x = 21 and both sides are 53 units long
Step-by-step explanation:
They are congruent, so they are equal, so
3x-10=x+32 then solve for x
2x=42
x=21
then plug x into each side to get its length
3x-10=3(21)-10=53
x+32=21+32=53
You would expect them to be the same since they are congruent

. Add the following. Answer in feet and inches. a) (3 ft. 8 in) + (4 ft. 9 in)
Answers
Answer:
8 ft. 5 in.
Step-by-step explanation:
First, let's change everything to inches
[] 3 ft. 8 in -> 3 * 12 = 36, 36 + 8 = 44 inches
[] 4 ft. 9 in -> 4 * 12 = 48, 48 + 9 = 57 inches
Now, we can add
44 + 57 = 101 inches
Last, we will simplify
101 -> 8 feet and 5 inches
