Answer:
set y = 0 to get the x intercept,,,,,,,,,, 0 = 2x -3 = x = 3/2 or 1.5
Step-by-step explanation:
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.
WE know 1 day = 24 hours
To find number of hours spent on each activity, we multiply the corresponding percentage by 24
School : 25 % --> 0.25 * 24 = 6.00 hrs
Eating : 10 % ----> 0.1 * 24 = 2.40 hrs
Sleep : 40 % ----> 0.4 * 24 = 9.60 hrs
Homework: 10 % ---->0.1 * 24 = 2.40 hrs
Free time: 15 % -----> 0.15 * 24 = 3.60 hrs
Answer:
A.)x=3 m=6
Step-by-step explanation:
A.)3 multiplied by two is 6, (B.) m=120 120/2 x=60
Answer:
Step-by-step explanation:
The graph passes through: (0,2) and (2,0)
The slope is
The equation of the line in point-slope form is given by:
The graph passes through (4,-2).
We substitute the slope and this point to get:
The first option is correct
