Pretty sure x is 4 in #9
FG is congruent to ED, and GD and FE are parallel, so that means
16x + 1 = 65
Subtract 1 on both sides you get
16x = 64
Divide by 16 on both sides
x = 4
Answer:
B
Step-by-step explanation:
The answer is B because if you move two times to the right it gives you 0.09 like the eqution.
But scientific notation requires number without decimal, so the answer cannot be E because 0.9 is a decimal.
Just reminder: B and D have the same result!! just different coefficient
For this problem plug in the given x and y values:
For the first one: No
second one: No
third one: Yes
fourth one: No
x = number of months
7*x = 7 times the number of months
7*x = total cost if you ignore the $100 fee
7x+100 = total cost with the fee of $100 included
y = total cost
y = 7x+100
Final Answer: y = 7x+100
note: the slope is 7 and the y intercept is 100
