Find the balance in an account with $4,250 principal earning 3% interest compounded quarterly after 12 years. Round your answer
Marat540 [252]
X = principle ( 1 + rate/compound rate) ^ years

x = 4250[1+(0.3/4)]^12
x = 4250(1+0.075)^12
x = 4250(1.075)^12
x = 4250(2.38178)
x = $10,122.23

What is the equation of the line that passes through the point(-5,-4) and has a slope of -3/5?
Elodia [21]

Answer:

y= mx+c

-4= -3/5(-5) + c

-4= -3/5 *-5+ c

-4=3+c

-4-3=c

-7=c

therefore the equation of the line is y=-3/5x-7

Step-by-step explanation:

the equation of a line is

y=mx +c

where y is the y coordinate

where m is the slope

where x is the x coordinate

where c is the y- intercept

What linear function equation can be represented by the set of ordered pairs? {(−4, −6), (0, −3), (4, 0), (12, 6)} Enter your an
dalvyx [7]

Answer:

The equation of the line is y = 3/4x - 3

Step-by-step explanation:

To find the equation of the line, pick any two points and find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (6 - 0)/(12 - 4)

m = 6/8

m = 3/4

Now that we have the slope, we can use the slope and point-slope form to find the equation in slope intercept form.

y - y1 = m(x -x1)

y - 6 = 3/4(x - 12)

y - 6 = 3/4x - 9

y = 3/4x - 3
