Step-by-step explanation:

points (-7,5) and (5,-3)?

This would mean to subtract the y coordinates:

5 - (-3) = 8

Then subtract the x coordinates in the same order:

-7 - 5 = -12

Then divide the y result by the x result for the slope:

8/-12 is the slope.

In simplest form, this is equivalent to -2/3

castortr0y [4]
To solve this problem you might have to use this formula y=a(1+r)^t A=amount of money you already have 1= a set number R= rate T= time  YOUR GIVENS ARE: A=4000 R= 3.5% (0.035) decimals T= 3 years NOW lets plug IN everything in the FORMULA y=4000(1+.035)^3= $4434.87. NOW lets subtract 4000-4434=434. She earned $434 of simple interest.

Answer:

1) \frac{7}{8}+\frac{2}{5}=\frac{7\times5+2\times8}{40}=\frac{35+16}{40}=\frac{51}{40}.

2) 2\frac{1}{3}\times \frac{1}{4}=\frac{7}{3}\times\frac{1}{4}=\frac{7}{12}

hence, answer is 7/12.

3) We have to divide £72 in the ratio 2:3:1

the total of the ratio is=2+3+1=6

so on dividing 72 into 6 parts we have 72/6=12

First '2' parts=2×12=24

second '3' part=3×12=36

last '1' part=1×12=12

so dividing £72 in the ratio 2:3:1 is: £24,£36 and £12

4) 39 people out of 65 have blonde hair.

Number of people who do not have blonde hair=65-39=26

percentage people who do not have blonde hair is given by:

=\frac{26}{65}\times100\\ \\=40%

Hence, percentage people who do not have blonde hair is 40%

5) 20% of 90= (20/100)×90

                       =18

Hence, 20% of 90 is 18.

6) Factorise

  2x^2+18x^3=2x^2(1+9x)\\\\2x^2+18x^3=18x^2(x+\frac{1}{9})

7) Expand

(y-8)(y-6)=y(y-8)-6(y-8)=y^2-8y-6y+48\\\\(y-8)(y-6)=y^2-14y+48

8)

x^2+4x+3=x^2+x+3x+3=x(x+1)+3(x+1)=(x+3)(x+1).

9)

y^{0}=1

10)

0.0342=3.42\times10^{-2}

11) x= -4 y=3

and z=4 x-y^3

z=4×(-4)-3^3

z= -43

12) y+2x=x-2\\\\2x-x=-y-2\\\\x=-y-2

13) 8-7x=22\\\\7x=8-22\\\\7x=-14\\\\x=-2

Hence x= -2

14) 5,10,15,20,....a_{1}=5=5\times1 , a_{2}=10=5\times2 , a_{3}=15=5\times3,........,a_{n}=5n=5\timesn

Hence,  nth term is 5n.

15) (63×128)/32.9=245.106.

16) 938×21=19698.

Answer:

Step-by-step explanation:

S  50 m = 0.050 km

A  ∵ 1 m = 100 cm

    ∴ 5 m = 500 cm

K  ∵ 1000 dm = 0.1 km

    ∴ 1 dm = \frac{0.1}{1000} km

    ∴ 5246 dm = \frac{0.1}{1000}\times 5246 km

                        = 0.5246 km

P ∵ 1 m = 1000 mm

  ∴ 5.246 m = 5246 mm

P ∵ 1 hg = 1000 dg

   ∴ 3.7 hg = 3700 dg

U  ∵ 1 g = 100 cg

   ∴ 0.37 g = 37 cg

E  ∵ 1 kg = 1000 g

   ∴ 370 kg = 370,000 g
