Point slope form
y-y1=m(x-x1)
m=slope
(x1,y1) is a point
(-5,-1)
x1=-5
y1=-1
m=-5/4
y+1=-5/4(x+5)
y=-5/4x-29/4
Answer:
3
Step-by-step explanation
The answer is three because if you did the tree method you will have the same exact answer
Answer:
The meeting room must be rented for less than 7 hours
Step-by-step explanation:
There are 2 types of costs in this situation
Fixed cost = $ 33
Variable cost = 9.70t
Where t is the number of hours.
The total cost C will be the sum of the fixed cost and the variable cost
We want C to be less than 100.90
So:
We solve for t and obtain.
Use the addition and subtraction theorem:
sin (A + B) = sin A + cos B
sin (A - B) = sin A - cos B
From there it's just a matter of simplification.
sin A cos B = 1/2 [ sin (A + B) + sin (A - B) ]
sin A cos B = 1/2 [ sin A cos B + cos A sin B + sin (A - B) ]
sin A cos B = 1/2 [ sin A cos B + cos A sin B + sin A cos B - cos A sin B ]
sin A cos B = 1/2 [ 2 sin A cos B ]
sin A cos B = sin A cos B
Answer:
Step-by-step explanation:
m = 2 ; x1 = -3 ; y1 = -1
Slope- point form: y - y1 = m(x -x1)
y - [-1] = 2(x - [-3])
y + 1 = 2(x + 3)
y + 1 = 2x + 3*2
y + 1 =2x + 6
y = 2x + 6 - 1
y = 2x + 5 This is slope intercept form : y = mx + b
