Put y in the x+2y-6. x+2(3x-7)=0. So x+6x-14=0. 7x-14=0. 7x=14. x=2
4. By the fundamental theorem of calculus,


is increasing on those intervals where

. So you have

which is clearly positive for

, and in the second interval you have

Together, this means

for all

.
5. When

,

reduces to

, so you have


Answer:
y=4 mm
Step-by-step explanation:
All angles in a triangle add up to 180: 180=∠M+∠P+∠N, ∠M=180-60-90=30
<u>Use sine rule</u>
a/sinA=b/sinB
PN/sin∠M=PM/sin∠N
y/sin30=8/sin90
y=8/1 *sin30
y=8*0.5
y=4 mm
Answer:
43
