2x-5y=4. 2x−5y=4. Add 5y to both sides. Add 5y to both sides.
2x=4+5y. 2x=4+5y. The equation is in standard form. The equation is in standard form.
2x=5y+4. 2x=5y+4. Divide both sides by 2. ...
\frac{2x}{2}=\frac{5y+4}{2} 22x=25y+4 Dividing by 2 undoes the multiplication by 2. ...
x=\frac{5y+4}{2} x=25y+4 Divide 4+5y by 2.
Step-by-step explanation: How do I determine how many solutions an equation has?
If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.
Answer:f(x)= 3*1/k
8=3*1/k
K=3/8
When x=2
f(x)=2*3/8
f(x)=3/4
Step-by-step explanation:
First, find the coordinates of all the points.
Then since we're dealing with a scale factor of 1/3 and we're assuming that it is about the origin, all you need to do is divide the coordinates by 3.
ex : (9,3) --> (3,1)
Answer:
-9
Step-by-step explanation:
C + D
-----------
C - D
= 8/11 + 10/11
- - - - - - - - - -
8/11 - 10/11
=18/11
- - - - -
- 2/11
=18/11 x 11/-2
= - 9
