Answer:
1. 3.5
2. -2
Step-by-step explanation:
1. 4x -5=9 (given)
4x = 14 ( addition property of equality) ( add 5 to both sides)
x = 3.5 ( division property of equality) ( divide both sides by 4)
2. 2x + 7 = 3 (given)
2x = -4 ( subtraction property of equality) ( subtract 7 for both sides)
x = -2 ( division property of equality) (divide both sides by 2)
Answers:
1.) x = 3.5
2.) x = -2
380 cups
Total cups=160
If 160 cups food lasted for 40 days then
Food lasted for 1 day=160/40
=4 cups
Amount of food required for 95 days=95×4
=380 cups
2. y=cos x is -pi/2,0 and pi/2/0
3. y= tan x is pi/2, 3pi/2
4. y=sin x is (0,0) and (pi/2,1)
5. y= csc x is (-pi/2,-1) and (pi/2,1)
d(n)=8−6(n−1)
d(6) = 8-6(d-1)
d(6) = 8-6*5
d(6) = 8-30
d(6) = -22
Answer:y=2x+10
Cost is 22.00
B=10 m=2
C=2(6)+10
C=12+10
C=22.00
