Answer:
Step-by-step explanation:
<u>Given</u> :
4 cancels throughout.
<u>Solving by quadratic formula</u> :
∴ Hence, the x-intercepts are (1, 0) and (-3, 0). The roots of the equation are 1 and -3.
Answer:
The solution of given problem is k = 11
Step-by-step explanation:
<u>slope of given two points formula:-</u>
slope m = .....(1)
Given points are (1,3) and (5,k)
given slope m = 2
now substituting m =2 and the given points are (1,3) and (5,k)
on simplification we get solution
Answer:
1) .
2)
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:
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
7) Expand
8)
.
9)
10)
11) x= -4 y=3
and z=4 x-y^3
z=4×(-4)-3^3
z= -43
12)
13)
Hence x= -2
14) 5,10,15,20,....
Hence, nth term is 5n.
15) (63×128)/32.9=245.106.
16) 938×21=19698.
