The number of real zeroes are the x intercepts or where the graph touches the x axis
negative leading coeficnet means it opens down
negative y coordinate means that the highest point is below the x axis
since it opens down and it is below the x axis, there is no x intercept or real solution (see attachment)
thereforr there are no real roots, there are zero real roots, nada, zip
The answer should be -14/16
Answer:
The correct option is option;
A. Flip
Step-by-step explanation:
When both sides of an inequality is divided by a negative number, it changes the sign of both numbers while their magnitude remain the same;
Therefore, if the right hand side of the inequality is lesser than the left hand side, when the signs of the left and right hand sides of the inequality changes after a division , by a negative number, we have;
The smaller right hand side of the inequality will then have a lesser negative magnitude than the left hand side of the inequality with a higher negative value and the left hand side (with the higher negative value) becomes lesser than the right and therefore, the symbol (sign) of the inequality is flipped
Therefore, when you divide both sides of an inequality by a negative number, you need to <u>flip</u> the inequality symbol.
Answer:
a<b+1
Step-by-step explanation:
a +2<b+3
a<b+3-2
a<b+1

second question:
January: 32 · 22 + 38 · 18 = 704 + 684 = 1388
December: 18 · 22 + 40 · 18 = 396 + 720 = 1116
1388 - 1116 = 272
Answer: $272.
