Step-by-step explanation:
if it asks for parallel it will always be the same slope
ANSWER
a) One Solution
b) the solution is x=2
EXPLANATION
The given equation is:
We expand to get;
Group similar terms;
This implies that,
Divide both sides by 10 to obtain,
Answer:
10. x= 10 y=sqrt 200
11. x=y=450
12. x=19 y=sqrt 1083
13. x=sqrt 48 y=sqrt 12
Step-by-step explanation:
10.
x and 10 are the same
10^2+10^2=200
sqrt 200 is not a whole number so y is just sqrt 200
11.
30^2=2x^2 because x and y are the same
x^2=450
sqrt 450 is not a whole number so x and y are just sqrt 450
12.
x= 38 divided by 2=19
38^2=19^2+y^2
1444=361+y^2
y^2=1083
sqrt 1083 is not a whole number so y is just sqrt 1083
13.
x^2=(x/2)^2+36=x^2/4+36
x^2=48
sqrt 48 is not a whole number so x is just sqrt 48
y is half of x so it is sqrt 12
Answer:
the cost of the table is 
the cost of the chair is 
Step-by-step explanation:
Let
x-----> the cost of the table
y----> the cost of the chair
we know that
-----> equation A
-----> equation B
substitute equation B in equation A
Find the value of x
