Answer:
Step-by-step explanation:
Answer:
z = 105°
Step-by-step explanation:
See attachment.
1. The angle z plus 105° is equal to 180°, the straight line. Z must therefore be = 105°
2. Angles z and (15x + 45°) must be equal to 190°.
x is therefore equal to 4.
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
Answer: Hello mate!
We have the equation 2x^2 + x = 14
let's solve it for x:
2x^2 + x - 14 = 0
the solutions can be obtained with the equation:
then the solutions are:
(-1 - 10.63)/4 = -2.907, that rounded to the hundreths is equal to -2.91 (because the number after the hundredth place is a 7, so we round up)
and
(-1 +10.63)/4 = 2.407, that when rounded to the hundreths place is equal to 2.41 (the same reason as before)
then the answers are -2.91 and 2.41
