Answer:
<h2>x = -2, y = 1</h2>
Step-by-step explanation:
given the system of equations y=1/2x+2 and y=-2x+-3, since the 2 equations are functions of y, we will equate both equations together and calculate the value of x as shown
1/2x+2 = -2x-3
x/2+2x = -3-2
5x/2 = -5
5x = -10
x = -10/5
x = -2
Substituting x = -2 into any of the equation to get the value of y we have;
y = -2(-2)-3
y = 4-3
y = 1
The solution to the system of equation (x, y) = (-2, 1)
Answer:
x
Step-by-step explanation:
<em>503 / 100</em>
<em>Convert the mixed number 5
3
100 into an improper fraction first by multiplying the denominator (
100
) by the whole number part (
5
) and add the numerator (
3
) to get the new numerator. Place the new numerator (
503
) over the old denominator (
100
)

Answers:
- cos(2theta) = -119/169
- cos(theta) = -5/13
=====================================================
The given info is:
- sin(theta) = 12/13
- theta is in quadrant II
From that, we can use the pythagorean trig identity to find that cos(theta) = -5/13. Keep in mind that cosine is negative in quadrant II.
Now use the trig identity below to compute cos(2theta)
