How many solutions does this have? y=5x+-2 y=5--2x
1 answer:
Answer:
one solution (2.333, 9.6666)
Step-by-step explanation:
The ys have to be equal for there to be 1 solution. Let's see if they are. Equate the ys. - -2x becomes 2x
5x +-2 = 2x + 5 Write the left with 1 sign
5x - 2 = 2x + 5 Subtract 2x from both sides
<u>2x 2x</u>
3x - 2 = 5 Add 2 to both sides
<u> 2 2</u>
3x = 7 Divide by 3
x = 7/3
x = 2 1/3
y = 5x - 2
y = 5(2 1/3) - 2
y = 11 2/3 - 2
y = 9 2/3

Answer:
B) No Unique Solutions
Step-by-step explanation:
Given:
now we now the value of y = 2 so we will substitute in equation
Now, We have value of y=2 and value of Substituting in both the value in equation
which means that the equation has Infinite solutions.
Answer:
Reference angle will be 30°
sin(330°) will be equal to
cos(330°) will be equal to 0.866
Step-by-step explanation:
We have given angle is 330°
As the angle is in forth quadrant
We know that in forth quadrant the reference angle is given by
Reference angle
As the angle is 330°
So the reference angle will be
Now we have to find the value of
sin(330°)
And now
