Y=11x+2 should be you answer for the slope
Answer:
x=2 and y= -3
Step-by-step explanation:
This is a simultaneous equation. To solve this type of equation, there are three methods; substitution, Elimination and Graphical.
But here, we would be using the substitution method.
3x-y=9 Equation 1
2x-y=7. Equation 2
Getting y from equation 2, we have
-y= 7-2x
Multiply both sides by -
y= 2x-7 Equation 3
Substituting y for 2x-7 in equation 1, we have
3x- (2x-7)=9
3x-2x+7=9
x+7=9
x=9-7
x=2
Substituting x as 2 in equation 3
y=2x-7
y= 2(2)-7
y= 4-7
y= -3
Q=2*s*L(T2-T1)/ (R2/R1)
1500000=2*30*10(275-22)/(R2/6)
1500000=600(253)/(R2/6)
1500000R2=600*253*6
1500000R2=910800
R2=910800/1500000
R2=0.6072.
The answer to your question is D
Answer:
The answer would be B i think .
