Answer:
What the following?
Step-by-step explanation:
Answer:
C)No Solution
Step-by-step explanation:
Given 2 equations
Mentioned to solve using eliminations method
4x-2y=1
2x-y=2
Multiply second equation with 2
⇒second equation is 4x-2y=4
Now subtract second equation from 1st equation
4x-2y-(4x-2y)=1-4
4x-4x-2y+2y=-3
0+0=3
0=3
But 0≠3
Therefore there exists no solutions for the given pair of equations
Both equations are Parallel lines as they have the same slope
For problems like these, we can set both sides of the equation equal to y. This is because both sides of the equation are equal to each other. If we were to take the left side of the equation and set it equal to y, the right side would also be equal to y. Similarly, if we were to set the right side of the equation equal to y, the left side of the equation would also be equal to y. Setting both equations equal to y will produce two equations which can be used in a system of equations.
Thus, our answer is:
y = (1/6)x - 5
y = (1/5)x + 2
Answer:
<em>(18 , - 10) </em>
Step-by-step explanation:
5x + 4y = 50 .... <em>(1)</em>
x + 2y = - 2 ... <em>(2)</em>
Solve (2) for "x"
x = - 2y - 2 .... <em>(3)</em>
(3) ----> (1)
5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ <u><em>y = - 10</em></u> .... <em>(4) </em>
(4) ----> (2)
x + 2(- 10) = - 2 ⇒<u><em> x = 18</em></u>
<em>(18, - 10)</em>
Answer:
Arithmetic content = 300 pages
Geometric content = 180 pages
Step-by-step explanation:
Arithmetic : Geometry = 5 : 3
Total pages of book = 480
How much of each type of content will be needed to make a book of 480 pages?
Total ratio = arithmetic + geometric
= 5 + 3
= 8
Arithmetic content = 5 / 8 × 480
= 0.625 × 480
= 300
Arithmetic content = 300 pages
Geometric content = 3 / 8 × 480
= 0.375 × 480
= 180
Geometric content = 180 pages
