Answer: there is no solution
Step-by-step explanation: 1/4z — 13 is not the same as 1/4 + 13
Say z = 1 that would simplify as -12 3/4 = 13 1/4 they are not the same so there is no solution
Answer:
Step-by-step explanation:
Given :
........................... equation 1
........................... equation 2
solving by substitution method , substitute into equation 1 , that is
substitute into equation 2 to find the value of y , that is
Answer:
x = 14, y = 37.
Step-by-step explanation:
9x + 12 = 4y - 10 (exterior alternate angles are equal)
9x - 4y = -22 ..........A
The angle which is interiorly alternate to 3x is 180 - (9x + 12), so:
3x = 180 - (9x + 12) (interior alternate angles are equal)
3x + 9x = 168
12x = 168
x = 14
Substitute x = 14 into equation A:
9(14) - 4y = -22
4y = 9(14) + 22
4y = 148
y = 37.
ANSWER
D. Quadrant IV
EXPLANATION
means the sine ratio is negative.
also means the tangent ratio is negative.
The only trigonometric ratio that is position in the fourth quadrant is the cosine ratio and its reciprocal, the secant ratio.
The tangent ratio and the sine ratio, with their reciprocals as well are negative in the fourth quadrant.
Hence the angle,
is in the fourth quadrant.
The correct answer is D.
Multiply the whole thing by (3a/3a) to get (6a)/(3+1)=6a/4=3a/2, so ya, 2nd is correct
