Substitute the value in for x and evaluate.
x^2+4x+4
Answer:
m=1/2 b =6
Step-by-step explanation:
m is the the gradient ( as in how much that line slant), so just use the formula
y2 - y1
------------
X2 - x1
For b, that the y-intercept,
Once u found m
Just choose any one of the coordinate they gave u (4,8) or(-6,3)
It will give u the same answers
Let's say u chose (4,8)
Theredore x = 4, y =8
y=mx + b
8= 1/2 x 4 + b
b= 6
The other one would give u the same answer
30 it is 30 i double checked
Answer:
A
Step-by-step explanation:
To answer this, we need to see what happens to the curves on the given interval
For f(x), we have that there is a decrease as we are moving from a higher positive value of y to a lower positive value of y over the specified interval
For g(x), we can see that we are moving from a lower positive y value to a higher positive y value
What this mean is that the first option is correct
18+2.50=20.50 so tax is 10% so you can put that into a calculator as 20.50*0.10 which equals 2.05 so just add 20.50 and 2.05 which is 22.55 is your final answer
