Answer:
(1). 450 degree and 90 degree.
(2). - 270 degree and - 990 degree.
Step-by-step explanation:
So, we are given the the following data or parameters in this question or problem; A = -630 degree, and we are to look for the next two positive and two negative angles that are coterminal with the given quadrantal angle.
For the positive(+ve) angles we have that;
- 630 degree + 1080 degree = 450 degree; and - 630 degree + 720 degree= 90 degree.
For the negative(-ve) angles we have that;
- 630 degree + 360 degree= - 270 degree and - 630 degree - 360 degree = - 990 degree.
Answer:
<h2>x = 4</h2><h2>y = 3</h2>
Step-by-step explanation:
2x - 3y = - 1 ………… Equation 1
y = x - 1 ….……….… Equation 2
To solve using substitution , substitute equation 2 into equation 1
That's
2x - 3( x - 1) = - 1
2x - 3x + 3 = - 1
- x = - 1 - 3
- x = - 4
Multiply through by - 1
We have
<h3>x = 4</h3>
Substitute x = 4 , into y = x - 1
We have
y = 4 - 1
y = 3
We have the answers as
x = 4
y = 3
Hope this helps you
