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:
4³
Step-by-step explanation:
2 / 2 = 1
4 raised to the power of one is 4
4 raised to the power of 3 is 4³
3O=12/3 Divide both sides by 3.
/3
O=4

2(4)+18=2∆
8+18=2∆
26=2∆
/2 /2 Divide by 2
∆=13
