Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:
That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.
For example,
and
would work, but so would
and
Answer:
B: 60
Step-by-step explanation:
f(x)= 5x+10, if x=10
f(10)=5(10)+10
5(10)+10=60
f(10)=60
Answer:
x = 4
y = 2
Step-by-step explanation:
by using substitution method ;
now, in second equation ;
- 2x + 3y = 14
- 2 (8 - 2y) + 3y = 14
( since x = 8-2y, from equation 1 )
- 16 - 4y + 3y = 14
- 16 - y = 14
- -y = 14 - 16
- -y = -2
- y = 2
<em>i</em><em> </em><em>hope</em><em> </em><em>it</em><em> </em><em>helped</em><em>.</em><em>.</em><em>.</em>
putting value of y in equation 1, we get :
- x + 2y = 8
- x + (2 × 2) = 8
- x + 4 = 8
- x = 8 - 4
- x = 4
Answer:
the answer is seven - eighths i think
Step-by-step explanation:
Answer:
( d / c ) < ( a / d )
( b / d ) < ( a / d )
( d / a ) < ( a / d )
Step-by-step explanation:
For this problem, we need to consider the given information that a > b > c > d > 0. Note that a is the greatest number and that d is the least number.
Given this fact, we can create a fraction that will result in a maximum value by simply doing the following:
a / d
The reason the fraction ( a / d ) results in a maximum, is because of the given information where a is the furthest from 0, and d is the closest to 0. Therefore, we can say that no other combination will result in a value greater than ( a / d).
So in the three given statements, we have different combinations of fractions being compared to our maximum value fraction. Our maximum value fraction ( a / d ) will always be greater than any other combination.
Thus, we will choose the sign that makes ( a / d ) greater than the other choice fractions.
Cheers.
