The first equation must be multiplied by 18 and second equation must be multiplied by 8
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
--------- eqn 1
-------------- eqn 2
Multiply the second equation by 8 both sides to remove the fraction in the variable y
Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y
Add eqn 3 and eqn 4
Thus the y-term is eliminated
Therefore, first equation must be multiplied by 18 and second equation must be multiplied by 8
Answer:
if the length of segment A'B' is 12 units, what is the scale factor of the dilation?
Step-by-step explanation:
Answer:
Step-by-step explanation:
Not sure if it was the question they asked buttt....
1.If y varies directly with x
Introduce the constant term k
2.y=kx
where k is the constant term
substitute the value of x and y to form the law
-1=3k
k=-1\3
:y=-1\3x....is the law
To find the value of y when x is 9
Reinstate the law which is y=-1\3x and substitute the value of x to find y
y=-1\3*9
y=-3
