Unit 5 lesson 1,2

By solving the inequality 6x - 7 > 5, the answer will be

• x > 2
• x > 7
• x < 2
• x = 2

By solving the inequality 18 - y > 9, the answer will be

• y < 9
• y < 18
• y = 9
• y > 9

By solving the inequality 4x - 16 < 0, the answer will be

• x = 4
• x > 4
• x < 4
• x < 16

2x+7≤5(x−4)

• The solution is x=4.
• The solution is x≥-3.
• The solution is x≤-3.
• The solution is x≤2.

In triangle XYZ , XZ > XY , then m (<Z) ………. m (<Y)

• biggger than or equal

In triangle ABC , AB = 8 cm , AC = 10 cm , then M(<B ) > m(<A) ?

• True

• False

In this figure is ….

• M(<ABE) > M(<ACD) .

• M(<ABE) < M(<ACD)

• No answer.

In triangle DEF, IF DE > EF , THEN m(<F) ……… m( <D)

M(<BAC) ………. M(BCA)

M(<DAC) …….. M(<DCA)

M(<BAD) ……. M(<BCD)

ABC IS A TRIANGLE, D IS THE MID POINT OF BC , IF THE PERIMETER OF TRIANGLE ACD > the perimeter of triangle ABD .

So is M(<B) > m(<C) .

• Yes

• No
