Answer:
1.15p - d
Step-by-step explanation:
The cost now is
p
With the 15% increase, the cost next year is
p + 15% of p =
= p + 0.15p
= 1.15p
With the discount of d dollars, the new rate will be
1.15p - d
Well the formula to find slope is m=
or (if that didnt work) y2-y1/x2-x1
so y2 is -9 and y1 is -3 so -9-(-3) is the same as -9+3 or -6
x2 is 8 x1 is -4 so 8-(-4) or 8+4 which is 12
-6/12 is equal -1/2
So the slope would be -1/2
Try to rewrite the equation;
You know that 5 can be written as log3(3^5)
log3(3^5)=log3(x^2+18) <-- you can now cancel out log3
3^5=x^2+18
243-18=x^2
225=x^2
√225=x
+-15=x
You see that even if x is negative, the squared will always give a positive answer. Therefore, +15 and -15 are both possible answers.
