Answer:
The correct answer is 450°, 810°, -270° and -630°.
Step-by-step explanation:
According to the given scenario, the calculation of the two positive angles and two negative angles i.e. coterminal is as follows:
The coterminal angles are the angles in which the difference could be 360 degrees or the multiples of 360 degrees
For 90 degrees, the two positive angles are
a. 90° + 360°
= 450°
450° + 360°
= 810°
b. The two negative angles are
= 90° - 360°
= -270°
-270° - 360°
= -630°
Okay so the formula for speed is speed = distance divided by time so 120 /4 is 30 for the first bar
House price = down payment + mortgage x number of months
430,000 = 250,000 + 2,000x where x is number of months
To find number or months solve for x
430,000 = 250,000 + 2,000x
Subtract 250,000
180,000 = 2,000x
Divide by 2,000
x = 90 months
12 months in one year
90 = 84 + 6 = 12 x 7 + 6
7 years and 6 months
Subtract 1/3x from the left side of the equation and subtract it from the right side of the equation. So it would be y = 4 - 1/3x
