Through the points (-1,-9) and (2,6) find the equation
vivado [14]
M= 6- -9 / 2- -1 = 6+9 / 2+1 = 15/3 = 5 
y-6=5(x-2) 
y-6=5x-10 
y=5x-4 

-9=5(-1)-4
-9=-5-4
-9=-9 

6=5(2) -4
6=10-4
6=6 

Step 1: find the slope using the formula m=y2-y1/x2-x1
Step 2: plug the slope and one point into the point-slope formula and solve to find the equation of the line in y=mx +b form.
Step 3: test both points to see if the equation works.

Suppose you have $200,000 in a bank term account. You earn 5% interest per annum from his account
iren [92.7K]

Answer:

$190,000

Step-by-step explanation:

discount = x

original price = $200,000

discount% = 5%

x/200,000 = 5/100

x · 100 = 5 · 200,000

100x = 1,000,000

100x/100 = 1,000,000/100

x = 10,000

Sale price: $200,000 - $10,000 = $190,000

Jamie has a piece of wood that is 6/8 inches long. He cuts the wood into pieces that are ¼ inches long. How many pieces of wood
pashok25 [27]
Answer: three pieces.

The piece of wood is 6/8 inches long - this fraction can be simplified to 3/4 by dividing both the numerator and denominator by 2.

Thus, he cuts a piece of wood that is 3/4 inches long into 1/4 inch pieces.

1 goes into 3 three times, so the piece of wood can be cut into three 1/4-inch pieces.

Find the compound interest and final amount $950 for 2 years at 7½ per annum​
wlad13 [49]

Answer:

1092.50 account value

142.50 interest

Step-by-step explanation:

to solve compound interest questions we use the formula A=P(1+rt) where P is the principal (initial investment) r is the rate or the return (7.5%) and t is the interval or time so 2 years

now putting it together we get A=950(1+ (7.5x2)) = 1092.50 $

the interest is this value A minus the initial investmetn so 1092.50 - 950 = 142.50$
