5x-2=3 -5 + 4y = 9 solve the system of equiations
Answer:
[tex]x=1,y=\frac{7}{2}[/tex]
Explanation:
Given the following question:
[tex]5x-2=3[/tex]
[tex]-5+4y=9[/tex]
To solve a system of equations we must start by solving the first equation for x, and then we substitute the value of x in in the second equation and then solve for y to find the value of both variables.
[tex]5x-2=3[/tex]
[tex]-5+4y=9[/tex]
[tex]-2+2=0[/tex]
[tex]3+2=5[/tex]
[tex]5x=5[/tex]
[tex]5x\div5=x[/tex]
[tex]5\div5=1[/tex]
[tex]x=1[/tex]
Substitute and solve the second equation:
[tex]x=1[/tex]
[tex]-5+4y=9[/tex]
[tex]-5+5=0[/tex]
[tex]9+5=14[/tex]
[tex]4y=14[/tex]
[tex]4y\div4=y[/tex]
[tex]\frac{14}{4} =\frac{7}{2}[/tex]
[tex]y=\frac{7}{2}[/tex]
Your answers are "x = 1, and y = 7/2."
Hope this helps.
Answer:
x=1 and y=7/2Explanation:
To solve this problem, isolate the term of x from one side of the equation.
5x-2=3 and -5+4y=9
5x-2=3First, add by 2 from both sides.
5x-2+2=3+2
Solve.
3+2=5
Rewrite the problem down.
5x=5
Divide by 5 from both sides.
5x/5=5/5
Solve.
5/5=1
x=1
-5+4y=9First, add by 5 from both sides.
-5+4y+4=9+5
Solve.
9+5=14
4y=14
Divide by 4 from both sides.
4y/4=14/4
Solve.
14/2=7
4/2=2
Rewrite as a fraction.
y=7/2
Dividing is another option.
7/2=3.5
y=7/2
Therefore, the correct answer is x=1 and y=7/2.
I hope this helps you! Let me know if my answer is wrong or not.

A man is crossing a river of width 100 m on a motorboat. The velocity of the motor boat is 4 m/s eastward and the velocity of the water current is 3 m/s northward. What is the resultant velocity of the boat and how much time will it take for the man to reach the other shore of the river?
Answer:
The resultant velocity of the boat = 5 m/s
The time it will take for the man to reach the other shore of the river = 25 s
Explanation:
width of river = 100 m
The velocity of the motorboat = 4 m/s eastward
The velocity of the water current = 3 m/s northward
The resultant velocity of the boat is:
R^2 = 4^2 + 3^2
= √ (4^2) + (3^2)
= √16 + 9
=√25
= 5 m/s
The time it will take for the man to reach the other shore of the river is:
d = 100 m
v = 4 m/s
t = d / v
t = 100 / 4
t = 25 s

What is a claim?It should be noted that a claim simply means the stance of an author in a literary work.
In this case, the claim is that warmer weather caused Galetown to have more severe rainstorms.
When the temperature of an air parcel begins higher, this will make it rise higher in the troposphere before the temperature of the air parcel and surrounding air are equal.

A bullet of mass 20g is horizontally fired with a velocity of 150m/s from a pistol of mass 2 kg. What is the
recoil velocity of the pistol?
Answer:
m1 = 20g (= 0.02 kg)
Mass of pistol, m2 = 2 kg
Initial velocity of the bullet (u1) and pistol (u2) = 0
Final velocity of the bullet, v1 = +150m s-1
Let v be the recoil velocity of the pistol.
Total momentum of the pistol and bullet after it is fired is
= (0.02 kg x 150 m s-1) + (2 kg x v m s-1)
= (3 + 2v) kg m s-1
Total momentum after the fire = Total momentum before the fire
3 + 2v = 0
→v = -1.5 m/s

What effect charged objects have on uncharged objects
Answer:
Uncharged objects: In spite of what the standard says, an uncharged object will not be attracted or repelled from a charged object. Instead, the charged object will cause the uncharged object to become charged, with a positive charge on one side and a negative charge on the other side. This process is called induction.

You work for the police. An accident has happened. A farmer was taking his dairy cows for milking across a road. The crossing point was 100m from a blind bend. In normal conditions with an alert driver obeying the speed limit of 30m/s a car can safely stop before reaching the crossing point. Mr Hoyland was driving home, saw the cows around the bend and was unable to stop. He ran into one of the cows and killed it.
Answer:
Since the stopping distance is less than the thinking distance, Mr Hoyland is therefore responsible for the accident
Explanation:
. In normal road conditions and with an alert and sober driver the car
could have stopped before the crash.
2. The reaction time of an alert and sober driver is 0.6s.
3. The reaction time of a drunk driver could be 2s.
4. The initial speed of the car was 30m/s
5. From the time of applying the brakes the total braking distance in
normal conditions is 70m
6. From the time of applying the brakes the total braking distance in bad
conditions is 90m
7. From the time of applying the brakes in normal conditions the car would
reach 15m/s in 52m
You are a forensic expert working for the police. You must analyse the facts and produce a
report stating whether or not Mr Hoyland was responsible for the accident.
1. Calculate the thinking distance for a car travelling at 30m/s
2. Calculate the braking distance for a car travelling in normal conditions at 30m/s
3. Calculate the total stopping distance.
4. REMEMBER TO SHOW YOUR WORKING OUT
Challenge:
1. Is Mr Hoyland responsible for the accident?
2. Explain your answer giving CLEAR reasons for your answer and likely causes.
The Thinking distance = 100m
The breaking distance = 70m
A breaking distance = Stopping distance = 70m
Since the stopping distance is less than the thinking distance, Mr Hoyland is therefore responsible for the accident

Science
By using optical and radio telescopes, the meteoroids are characterized and their shape, rotation and physical composition are determined.
Scientists have considered some criteria to detect the meteoroids and prevent collisions so that earth is protected from their impact. This includes finding the position and size of the meteoroids and so the orbit of the earth could be changed and thus there is possibility for preventing collision.
By using optical and radio telescopes, the meteoroids are characterized and their shape, rotation and physical composition are determined. With the early recognition of the meteoroid movement and their position, the evacuation of people from the particular areas of possible impact can be done.
