What is the value of the x variable in the solution to the following system of equations?
2x - 3y = 3
5x - 4y = 4
Answers
Answer:
x = 0
Step-by-step explanation:
Solve 2x - 3y = 3 for x:
[tex]2x - 3y = 3[/tex] [tex]2x - 3y + 3y = 3+ 3y[/tex] (add 3y to both sides)[tex]2x = 3y + 3[/tex] [tex]\frac{2x}{2} = \frac{3y+3}{2}[/tex] (divide both sides by 2)[tex]x = \frac{3}{2}y + \frac{3}{2}[/tex]Substitute 3/2(y) + 3/2 for x in 5x - 4y = 4
[tex]5x - 4y = 4[/tex] [tex]5(\frac{3}{2}y + \frac{3}{2}) - 4y = 4[/tex] [tex]\frac{7}{2}y + \frac{15}{2} = 4[/tex] (simplified both sides of equation)[tex]\frac{7}{2}y + \frac{15}{2} - \frac{15}{2} = 4 - \frac{15}{2}[/tex] (subtract 15/2 from both sides)[tex]\frac{7}{2}y = -\frac{7}{2}[/tex] [tex]\frac{7}{2}y * \frac{2}{7} = \frac{-7}{2} * \frac{2}{7}[/tex] (multiply both sides by 2/7)[tex]y = -1[/tex]Substitute -1 for y in x = 3/2(y) + 3/2
[tex]x = \frac{3}{2}y + \frac{3}{2}[/tex] [tex]x = \frac{3}{2}(-1) + \frac{3}{2}[/tex] [tex]x = -\frac{3}{2}+ \frac{3}{2}[/tex] (simplified both sides of equation)[tex]x = 0[/tex]Therefore, the value of the x-variable is 0.

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Sam invests a sum of money into an account that pays 3%
compound interest per annum
We need to find how many years Sam will have doubled his investment.
With C your initial capital, k the interest rate and t the number of years. Since k is given as a simple interest rate, you’re essentially trying to solve :
C(1+tk)=2C
With a little bit of algebra, you should find that:
t=1/k
k=3%=0.03
t=1/0.03=33.33=33 years.
Hence, Sam will have doubled his investment for 33 years.

Write the equation of the line that passes through the points(-6,8)and(0,-3). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line..
Answers
Remember, when you are calculating the slope from two given points, you are finding the change in y over the change in x.
P1 = ( x1, y1 )
P2 = ( x2, y2 )
m = Δy / Δx ---> m = (y2 - y1) / (x2 - x1)
Now let's assign the given points:
(-8, -6) --> x1 = - 8 & y1 = -6
(-4, 2) --> x2 = -4 & y2 = 2
Now, let's plug these values into the slope formula:
m = (y2 - y1) / (x2 - x1)
= (2 - (-6)) / ((-4) - (-8))
Let's simplify:
(2 - (-6)) / ((-4) - (-8))
= (8) / (4)
= 2
Therefore, the slope, or m, is 2.

Answer:
64 ounce bottle of orange juice has a greater percent of water
Step-by-step explanation:
Case 1) An 80 ounce bottle of apple juice contains 32 ounces of water
Total quantity of bottle = 80 ounces
Amount of water = 32 ounces
So, Percent of water = [tex]\frac{32}{80}[/tex] x 100
= 40%
Case 2) An 64 ounce bottle of orange juice has 48 ounces of water
Total quantity of bottle = 64 ounces
Amount of water = 48 ounces
So, Percent of water = [tex]\frac{48}{64}[/tex] x 100
= 75%
Hence 64 ounce bottle of orange juice has a greater percent of water

Answer:
x= 7
B= 112
F= 68
Step-by-step explanation:
to find x we set up an equation, (16x)=(4x+84). They are alternate interior angles which are always equal.
calculate it and you'll find x=7.
B and the angle 4x+84 are equal because they are vertical angles, to find it we just put 7 instead of x into 4x+84.
4(7)+84=112
angle f is supplementary to 16x. 16x is also 112 because they are equal, so its just 180-112=68
PROBLEM SOLVING A boat is traveling parallel to the shore along RT. When the
boat is at point R, the captain measures the angle to the lighthouse as 35º After the
boat has traveled 2.1 miles, the captain measures the angle to the lighthouse as 70°
Answers
The exterior angle theorem states that the sum of two opposite interior angles is equal to the measure of the exterior angle.
The distance SL= 5.77 miles between the boat and the lighthouse after travelling 2.1 miles
According to the conditions given in the problem the exterior angle is 70 degrees and one of the opposite interior angle is 35 degrees.
m∠ L + m∠R= 70°
m∠ L + 35° = 70°
m∠ L = 70°-35°
m∠ L = 35°
If one interior angle is 35 degrees the other must also be 35 degrees to make a total of 70 degrees.
The sum of all angles of the triangle is always equal to 180 degrees.
So the third angle of the triangle will be
180°= 35°+35°+m ∠S
m∠S= 110°
From the triangle
Angle theta= m∠S= 110°
Fy= SL= height
Fx= RS = base
F= RL= hypotenuse
The line SL has to be found out.
Let the Fx= 2.1 miles
Then
Fx= Fcos ∅
But Cos ∅ = Cos 110°= -0.342
2.1= F (-0.342)
F= - 6.140 = hypotenuse
Now the vertical component
Fy= Fsine theta
Fy= - 6.140 sine 110°
Fy= - 6.14×0.94
Fy= -5.77 miles
The negative sign indicates that it is in the opposite direction.

Work out the nth term of the following sequence:
7, 16, 31, 52, 79
its a quadratic sequence and i worked out the second difference (6) so know its 3n² but i don't know the rest
Answers
Answer:
Step-by-step explanation:
Since it is given that it is quadratic it is of the form f(n)=an^2 + bn+c.
Since we know a few terms we can plug in to get some equations:
f(1)= a +b+c = 7
f(2)=4a+2b+c = 16
f(3)=9a+3b+c = 31
Now you've got yourself a system of three equations which I trust you can solve.
