Given the pair of simultaneous equation:
y=-2/5x-2
y=5x+1
To evaluate the solution of the system of equation from the graph, we obtain the point at which the two linear equations have intersected. taking the values of x and y from the point of intersection that will be the solution of the system of linear equations.
In our case the straight lines have intersected at the point (-0.5, -1.75). This implies that:
x=-0.5
y=-1.75
hence the answer is a] (-0.5, -1.75)
Answer:
70%of x = 63
70/100 × x = 63
x=63×100/70
x=90
Step-by-step explanation:
Answer:
x=-1
Step-by-step explanation:
x^2+2x=16=0
Use the quadratic formula to find the solutions.
−b±√b2−4(ac)/
2a
Substitute the values
a=1, b=2, and c=−16 into the quadratic formula and solve for x
