Answer:
y = -9/4x
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= ( -9-9)/(4 - -4)
( -9-9)/(4+4)
-18/8
-9/4
Slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = -9/4 +b
Substitute a point into the equation
9 = -9/4(-4) +b
9 = 9+b
b=0
y = -9/4x
Answer:
6x, 2x + 4, 5y + 11
Step-by-step explanation:
x + x + x + 2x + x = 6x
(x + 2) + (x + 2) = 2x + 4
y + y + y + y + 10 + y + 1 = 5y + 11
Answer:
4.5(1.035)^t
Step-by-step explanation:
An inrease of 3.5% means that each year's total is 103.5% of the year before, right?
Year 1 = 4.5(1.035) = 4.66
Year 2 = 4.66(1.035) = 4.82
etc.
So, year 2 is 4.5(1.035)(1.035) = 4.82
Multiplying something by itself can be written with an exponent instead, so 2 years is...
4.5(1.035)2
Since the number of years is the variable (let's call it t)...
