Answer:
2X-3Y = -1
Step-by-step explanation:
given equation is 3X +2Y = -7
FIRST BRING THIS IN SLOPE INTERCEPT FORM
2Y = -3X -7
DIVIDING EACH TERM BY 2
Y = (-3/2)X -7/2
SLOPE OF GIVEN EQUATION IS -3/2
SLOPE OF LINE PERPENDICULAR TO THIS IS NEGATIVE RECIPROCAL HENCE SLOPE OF REQUIRED EQUATION IS 2/3
EQUATION OF STRAIGHT LINE IN POINT SLOPE FORM IS
Y-Y1 = m(X-X1)
Y-1 = (2/3)(X-1)
MULTIPLYING ALL TERMS BY 3
3(Y-1) = 2(X-1)
3Y-3 = 2X -2
2X-2 = 3Y-3
2X-3Y =-3+2
2X-3Y = -1
Answer:
66
Step-by-step explanation:
have a great day
6. 13
7. 262
8. ? For the first part but the sum is $118
9. ?
The is the concept of algebra, the weight of the spring can be modeled by the equation;
w=0.9sqrt E
where;
=energy in joules;
thus the weight of the spring when the energy is 12 j will be:
w=0.9sqrt12
w=3.18 g
