Write the equation in slope-intercept form of the line that has a slope of -7/8 and contains the point (-4, 9).
lubasha [3.4K]

Answer:

The equation of the line is y = -7/8x + 11/2

Step-by-step explanation:

Since we have the slope and a point to start, we can use point-slope form to find the equation.

y - y1 = m(x - x1)

Use the slope for m and the point at (x1, y1). Then solve for y.

y - 9 = -7/8(x + 4)

y - 9 = -7/8x - 7/2

y = -7/8x + 11/2

18,000 amounts to 21,600 in 4 years at simple interest. Find the sum of
AnnyKZ [126]

Answer:

\$20,400

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

step 1

Find the rate of interest

in this problem we have

t=4\ years\\ P=\$18,000\\ A=\$21,600\\r=?

substitute in the formula above and solve for r

\$21,600=\$18,000(1+4r)

1.2=(1+4r)

4r=1.2-1

r=0.2/4=0.05

The rate of interest is 5\%

step 2

Find the sum of  money that will amount to 25,500 in 5 years, at the same rate of interest

in this part we have

t=5\ years\\ P=?\\ A=\$25,500\\r=0.05

substitute in the formula above and solve for P

\$25,500=P(1+0.05*5)

P=\$25,500/(1.25)=\$20,400
