Answer:
The graphs are posted.
Step-by-step explanation:
the method to solve such inequalities is assume the line and then draw the line then search for the inequality
The y < 0.5x-3
First plot the line y=0.5x-3
Now all the values of y which are below the line satisfies the inequality.
similarly for the second question x+y ≥ 5.
Now assume the line x+y=5
All the values of (x , y) above the line satisfies the equation including the points on the line .
Answer:
Required number is 4.
Step-by-step explanation:
Let the required number be a.
Given,
Sum of ten times the integer and seven times it’s square is 152.
= > Ten times of a + seven times of it's square = 152
= > 10( a ) + 7( a )^2 = 152
= > 10a + 7a^2 - 152 = 0
= > 7a^2 + 10a - 152 = 0
= > 7a^2 + ( 38 - 28 )a - 152 = 0
= > 7a^2 + 38a - 28a - 152 = 0
= > a( 7a + 38 ) - 4( 7a + 38 ) = 0
= > ( a - 4 )( 7a + 38 ) = 0
= > a = 4 or - 38 / 7
Hence the required number is 4.
