Answer:
X=2
EF = 21
Step-by-step explanation:
19x-17= 51-15x
34x = 68
X=2
EF = 51- 15(2)=21
1)
P = 600
I = 0.07
N = 2
2)
P = 4000
R = 0.09
N =4
3)
P=6000
R = 12
I = .084
Let's say the TV cost $100
Now if we multiply 0.08(.85(100)) we'll first get $85 which is 15 percent off.
If we choose option A then that will be wrong because you're new total would be $15 dollars instead of $85
Option B when multiplied by .08 will bring the price of the TV all the way down to $6.80 which that doesn't make sense.
Multiplying by 1.08 will be considered as tax and therefore option C is correct.
Answer:
negative
Step-by-step explanation:
The graph has a negative slope because the line is pointing downwards.
You can check your answer numerically using the slope formula (y2 - y1 divided by x2 - x1) and substituting with two coordinates on the line.
For example:
(x1, y1)
(x2, y1)
y2 - y1
----------
x2 - x1
Solve by subtracting the numerator and denominator, then divide.
