First one: If the leading coeff. is negative, the graph begins in Quadrant III and ends in Quadrant IV. It's an even function. The fourth graph represents it.
If the leading coeff. is positive, but everything else remains the same, the graph opens upward, beginning in Q II and ending in Q I.
{ y = 3 x - 4
9x -3y = 14
Subsititute y = 3x-4 :
[ 9 x - 3 ( 3 x-14 )=14]
Refine:
9 x - 3 ( 3 x - 4 ) = 14
- 2 = 0
is false , therefore the system of equations has no solution
Answer A
hope this helps!
15*0.07= 1.05 so 7% of 15 is 1.05. we add this to the total so 7% tax is going to be a price of $16.05

Shaded part means the yellow part
- The two sets are S and Y.
- The centre intersection part is A
- All the areas occupied by both sets is AUB .
