Answer:
Step-by-step explanation:
The population of a city is 250,000 and the annual growth rate is 2.2%
General equation for exponential growth is
Where y is final population and P is the initial population
'r' is the rate of growth and x is the number of years
p = 25000 and r= 2.2%= 0.022. Replace all the values in the general equaiton
Answer:
$12.95 is the final cost for the oranges
$12 is the cost for apple
Step-by-step explanation:
The final cost for the orange is
30/100 x 18.50
=5.55
18.50-5.55
=$12.95
Answer: y=4x-10
Step 1: Write model equation
The model equation for slope- intercept form is y=mx+b
M-Slope
X-Variable
B- Y-intercept
Step 2: Slope
Since we know that m is slope, we can substitute the slope given (1/4) into the equation
y=mx+b
y=4x+b
Step 3: Y-intercept
The final thing we have to do is solve for the y-intercept, or b. We’ll do this by substituting the point into the equation and solving.
y=4x+b
*substitute point*
6=4(4)+b
*multiply 4 and 4*
6=16+b
*subtract 16 on both sides*
-10=b
Step 4: Check your answer
We will check our answer by substituting all the values into the equation and seeing if the left and right side equal each other
y=mx +b
6=4(4)-10
6=16-10
6=6
This is correct! Hope this helps comment below for more questions :)
Answer:
-5
Step-by-step explanation:
I think the m is for measure of line AB
P = 2(L + W)
P = 44
L = W + 2
44 = 2(W + 2 + W)
44 = 2(2W + 2)
44 = 4W + 4
44 - 4 = 4W
40 = 4W
40/4 = W
10 = W
L = W + 2
L = 10 + 2
L = 12
A = L * W
L = 12
W = 10
A = 12 * 10
A = 120 square inches <===
