As we know these two lines mean | | a modulus sign. The modulus symbol is sometimes used in conjunction with inequalities. A modulus sign in simple words just ignores the sign and gives us the absolute value.
For example in this case the modulus gives us 4 x 2 - 3. As you can see the modulus sign has ignored the original negative signs with the numbers.
So after evaluating the equation the answer comes out to be 8 - 3 which is equal to 5.
The saleprice is $13.5, so the discount is $1.5.
Answer:
y = x^2+3x-4 y=3x+5
(3, 14)
Step-by-step explanation:
hope this helps and have a nice day!! :)
And also you should try to use Desmos calculator it really helps with these problem/ equations!! you just have to put y = x^2+3x-4 then press enter and on the second one you put y=3x+5 and then it shows you a graph and plus the answer!! :))
Answer:
Rhion did better in maths test.
Step-by-step explanation:
Given that:
Rhion scored 14 out of 17.
We will find percentage and then compare them.
Percentage = 
Percentage = 
Percentage = 82.35%
Rhion scored 31 out of 39.
Percentage = 
Percentage = 79.48
On comparing,
82.35 > 79.48
Hence,
Rhion did better in maths test.
