What is the point-slope form of a line that has a slope of 5 and passes through the point (3, –4)?
Alex
The answer is: y - (-4)= 5(x-3)

Point slope form is:
y-y1=m(x-x1)

m is your slope. They tell us the slope is 5. They also give you an ordered pair. Substitute this ordered pair into the point slope equation for the x1 and y1 values.

The table shows interest owed for a home improvement loan based on how long it takes to pay off the loan.
Alexxandr [17]
Remember that  the formula for simple interest is:
I=prt
Where I is the interest to paid, p is the loan, r is the interest rate (in decimal), and t is the time (in years).

A. We know that the interest rate for a loan of 9 months is 2.9%, but we need to convert that rate to decimal. To do that just divide the interest rate by 100%:
\frac{2.9}{100} =0.029
Next, we are going to find the time t in years. Since the period of time is 9 months, we are going to dive by 12, the number of months in a year, to obtain the time in years:
t= \frac{9}{12} =0.75
Now, we just need to replace the values in our formula to find the interest owned:
I=(900)(0.029)(0.75)=19.58
We can conclude that <span>the interest owed for a home improvement loan of $900 after 9 months is $19.58.
</span>
B. Similarly:
r= \frac{3.1}{100} =0.031
t= \frac{18}{12} =1.5
I=(2500)(0.031)(1.5)=116.25
We can conclude that the interest owed for a home improvement loan of $2500 after 18 months is $116.25.

C. Similarly:
r= \frac{2.4}{100} =0.024
t= \frac{6}{12} =0.5
I=(5600)(0.024)(0.5)=67.2
We can conclude that the interest owed for a home improvement loan of $5600 after 6 months is $67.2

14 T 1,000 lb. + 2 T 1,000
Olegator [25]

The answer will be 17 tons.

Step-by-step explanation:

Since we have given that

14 T 1,000 lb. + 2 T 1,000 lb.

As we know that

1\ ton=2000\ lbs\\\\14\ tons=2000\times 14\ lbs\\\\14\ tons=28000\ lbs

So, 14 T 1,000 lb. is given by

28000\ lbs+1000\ lbs\\\\=29000\ lbs

Similarly,

1\ ton=2000\ lbs\\\\2\Tons=2\times 2000\ lbs\\\\2\ tons=4000\ lbs

so,

2T 1,000 lb. is given by

4000+1000\\\\=5000\ lbs

So,  14 T 1,000 lb. + 2 T 1,000 lbs is given by

29000+5000\\\\=34000\ lbs\\\\=\frac{34000}{2000}\\\\=17\ tons

Hence, the answer will be 17 tons.
