Answer:
see below
Step-by-step explanation:
2/3 +y =1/4
Subtract 2/3 from each side
2/3-2/3 +y =1/4-2/3
y = 1/4 -2/3
Get a common denominator
y = 1/4 (3/3) - 2/3 *4/4
= 3/12 - 8/12
=-5/12
or if
2/(y+3) = 1/4
Using cross products
y+3 = 2*4
y+3 = 8
y =8-3
y = 5
Equation in slope-intercept form is y = 2x - 6
Step-by-step explanation:
- Step 1: Given slope of the line, m = 2. Form an equation y = mx + b
⇒ y = 2x + b ---- (1)
- Step 2: The line passes through the point (4,2). So it will satisfy the equation. Find b by substituting x = 4 and y = 2.
⇒ 2 = 2 × 4 + b = 8 + b
⇒ b = -6
- Step 3: Form the slope-intercept equation.
⇒ y = 2x - 6
Answer:
Step-by-step explanation:
Recall that on the unit circle, each point is represented as 
where 
. In this case, we are asked to take a loot at the interval 
.
We will use the definition of tangent to solve the problem. REcall that
So, in this case, tangent is undefined whenever the denominator is zero. That is, when 
. Checking the unit circle with the interval , this restriction corresponds to the upper half of the unit circle. In this case, the x component of each point is cosine. We are interested at the points where .
. This happens only at the point (0,1), which is associated with the value of

The number of decimal places you move will be the exponent on the
10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
