Answer:
Example 5 If a force F1 = 100N is applied on the left in the hydraulic lift shown, where A1 = 0.02 m2 and. A2 = 0.08 m2, what force F2 will be.
Step-by-step explanation:
A) SUBSTITUTION: 4x + 3(-2x +8)=16
4x + -6x + 24 = 16
-2x= -8
x= 4
y= 0
b) ELIMINATION:
12x -8y = -76
-12x -15y = -39
-23y= -115
y=5
x= -3
c) ELIMINATION:
-12x+28y=36
12x-9y=21
19y= 57
X=4
y=3
d) SUBSTITUTION:
-4(23 -3y) +5y=-7
-92+12y+5y =-7
-92 +17y = -7
17y = 85
y=5
x=8
Answer:
The answer is A or the first one
Step-by-step explanation:
This is because the domain is signifying the x amounts. So, this line keeps going on and on, which is all real numbers. On the other hand, the range are the y’s. The y’s are staying on the -100 line or above.
Assuming the radical between 6b and 7 to be +.
<span>6-4(6b + 7) >122
6 - 4*6b - 4*7 > 122
6 - 24b - 28 > 122
-24b > 122 + 28 - 6
-24b > 144 When you divide by a -ve number the inequality sign reverses
b < 144/-24
b < -6
