Answer:
y intercept = - 40
Step-by-step explanation:
x 24 36 48
y -8 1 10
y = ax + b
a is the gradient (or slope).
b = y intercept.
a = (48-36) / (10-1) = 12/9
Rewrite to solve for b, which means it starts with b = ...
b = y - 12/9 * x
Substitute one point ( 24 , -8 )
b = -8 - (12/9 * 24)
b = y intercept = - 40
70 × 20%
70 × .20 = .14
so .70 - .14 = $.56
Answer: 150
Step-by-step explanation: so when you want a whole amount of something you want to the 100% of it because 100% is the whole thing right? Well right now you only have 20% so how much do you need to multiply that by to get 100%?? Well that answer is 5. Okay so now since $30 is 20% but we wanna get it to 100% multiply it by 5 so 30x5 which is 150
You would shade in 135 of the squares in the grid(s)
Answer:
1.49
Step-by-step explanation:
In order to find the slope of the tangent line to a given equation, and in a given point, we need to:
1. Find the first derivative of the given function.
2. Evaluate the first derivative function in the given point.
1. Let's find the first derivative of the given function:
The original function is 
But remeber that the derivative of
is 
so, 
2. Let's evaluate the first derivative function in the given point
The given point is (0.4,1.49) so:



Notice that the calculated slope of the tangent line is equal to the y-coordinate of the given point because f'(x)=f(x). In conclusion, the slope of the tangent line is equal to 1.49.
