-4a - 6 = -12
-4a = -12 + 6
-4a = -6
a = -6/-4
a = 6/4
a = 3/2
a = 1 1/2
The answer is c
Answer:
the solution is (-3, -2)
Step-by-step explanation:
Please, separate your equations with a (;) or a (.). Better yet, write only one equation per line:
y=2x+4
3x−6y=3
Substitute 2x + 4 for y in the second equation:
3x - 6(2x + 4) = 3, or
3x - 12x - 24 = 3
Combining like terms, we get -9x = 27, and so x = -27/9, or x = -3.
Since we know that y=2x+4, we replace x in this equation with -3 and calculate y:
y = 2(-3) + 4 = -2
Then the solution is (-3, -2).
Answer:√

Answer:
Fv = 79.63 lb
The total upward force Fv is 79.63 lb
Step-by-step explanation:
We need to determine the total upward force, the y component of force;
Given;
Force F1 = 60.5 lb, 82.4° above horizontal
Force F2 = 37.2 lb, (82.4-50.5)° above horizontal
The vertical component of Force F1 and F2 is;
Fv = 60.5sin(82.4) + 37.2sin(82.4-50.5)
Fv = 79.63 lb
The total upward force Fv is 79.63 lb
