I’m not sure what you want me to solve? Because the x values for this equation would be -7 and -2
Answer:
The length of QR is approximately 18.3 cm
Step-by-step explanation:
The given parameters are;
The length of the side PR = 23 cm
The length of the side PQ = 22 cm
The measure of the angle QPR = 48°
By cosine rule, we have;
Plugging in the values gives;
The length of QR ≈ 18.3 cm
Answer:
A linear system of three equations with three variables is any system that can be ... i) can be zero as long as each equation has at least one variable (x,y or z) in it. ... A solution to a system of equations are values of x, y and z such that, when ... x+y+z=4;4x+1/2y-3z=30;-2x-6y+5z=-7 · c+2d+3e=−13;3c+2d-e=-1;2c-d+2e=-4 Step-by-step explanation:
Answer:
y=1/2x-8
Step-by-step explanation:
Answer:
Reduce
Step-by-step explanation:
It will reduce because the factor is less than 1 so it cannot enlarge and it is not the same as the 1 so it cannot preserve.
