Area or permiter area is Base x Height perimeter is Side squared
Given -
y > - x + 3
To Find -
The points which is NOT a solution to the inequality
Step-by-Step Explanation -
We will put the value of each in inequality and then see if it satisfies the given condition or not.
a. ( -2,6)
So, x = -2 and y = 6 in y > - x + 3
= 6 > - (-2) + 3
= 6 > 5 (Correct Solution)
b. (5,-1)
So, x = 5 and y = -1 in y > - x + 3
= -1 > -5 + 3
= -1 > -2 (Correct Solution)
c. (2,0)
So, x = 2 and y = 0 in y > - x + 3
= 0 > -2 + 3
= 0 > 1 (Incorrect Solution)
d. (0,3)
So, x = 0 and y = 3 in y > - x + 3
= 3 > -0 + 3
= 3 > 3 (Incorrect Solution)
Final Answer -
The points which is NOT a solution to the inequality =
c. (2,0)
d. (0,3)
Answer:
Step-by-step explanation:
A bag contains yellow and blue blocks in the ratio 1:3
Sum of Proportion = 1 + 3 = 4
There are 8 more blue blocks than yellow blocks.
b = y + 8
y = b - 8
(a) How many yellow blocks are there?
For yellow block
= 1/4 × x = ( b - 8)
(b) How many blue blocks are there?
3/4 × x = ( y + 8)
Substitution is the way I would solve it
Answer:
open brackets we get
6x³ - 9x² + 6x + 10x² - 15x + 10
6x³ + x² -9x + 10
