13.	What is the point-slope form of a line that has a slope of 3 and passes through the point (–1, 4)?y – (–1) = 5(x – 4)4 – y1 = 3(–1 – x1)y – 3 = –1[(x – (–4)]y – 4 = 3[(x – (–1)]
Answer» GIVEN: Slope of a LINE is 3 and it passes through the point (–1, 4). To FIND: The point-slope form of the line. Solution: Point-slope form of a line that is passes through $(x_1,y_1)$ with slope m is $y-y_1=m(x-x_1)$ Slope of the line is 3 and it passes through the point (–1, 4). So, the point slope form of the line is $y-4=3[x-(-1)]$ Therefore, the correct OPTION is D.

What is the point-slope form of a line that has a slope of 3 and passes through the point (–1, 4)?y – (–1) = 5(x – 4)4 – y1 = 3(–1 – x1)y – 3 = –1[(x – (–4)]y – 4 = 3[(x – (–1)]

Answer»

GIVEN:

Slope of a LINE is 3 and it passes through the point (–1, 4).

To FIND:

The point-slope form of the line.

Solution:

Point-slope form of a line that is passes through $(x_1,y_1)$ with slope m is

$y-y_1=m(x-x_1)$

Slope of the line is 3 and it passes through the point (–1, 4). So, the point slope form of the line is

$y-4=3[x-(-1)]$

26.

selling price of 10 articles is the same the cost price of 11 articles, find the gain or loss percentage

Answer»

Answer:

9 1/11 %

Step-by-step explanation:

Let the CP of 1 ARTICLE be Rs.1

CP of 10 articles = Rs.10

CP of 11 articles = Rs.11

SP of 10 articles = Rs.11

Hence, gain = Rs.(11-10) = Rs.1

Gain% = (1/11 × 100)% = 100/11 % = 9 1/11 %

by what percent less is the simple interest on rs 4500 for 8 years at 8% per annum than the early compound interest on rs4000 for 3 years at 10% per annum.

Answer»

Step-by-step explanation:

for 8 years simple interest = (4500*0.08)*8 = 2880₹

compound interest 1st year = (4000*0.1) =400

total = 4400

2nd year ci = (4400*0.1)=440

total = 4840

3rd year ci = (4840*0.1)=484

total 3 years ci = 400 + 440 + 484

= 1324₹

difference between ci & si = 2880 - 1324 = 1556₹

Answer»

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Compound\:Interest=10,123.2\:rupees}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{\underline \bold{<klux>GIVEN</klux>: }} \\ \tt: \implies Principal(p) = 25,000 \: rupees \\ \\ \tt: \implies Rate\%(r) = 12\% \\ \\ \tt: \implies Time(t) = 3 \: years \\ \\ \red{\underline \bold{To \: Find: }} \\ \tt: \implies Compound \: Interest = ?$

• ACCORDING to given QUESTION :

$\bold{As \: we \: know \: that} \\ \tt: \implies A = p(1 + \frac{r}{100} )^{t} \\ \\ \tt: \implies A =25000(1 + \frac{12}{100} )^{3} \\ \\ \tt: \implies A =25000 \times (1 + 0.12)^{3} \\ \\ \tt: \implies A=25000\times (1.12)^{3} \\ \\ \tt: \implies A = 25000 \times 1.404928 \\ \\ \green{\tt: \implies A =35,123.2 \: rupees} \\ \\ \bold{For \: compound \: Interest} \\ \tt: \implies C.I = A - p \\ \\ \tt: \implies C.I= 35123.2 - 25000 \\ \\ \green{\tt: \implies C.I =10,123.2 \: rupees}$
