Answer:
True
Step-by-step explanation:
The nature of roots of a quadratic equation are determined by
where a, b, and c are the coefficients of the quadratic equation
Therefore it is true that, the roots of a quadratic equation depend on the values of the coefficients.
Answer:
A. The graph is not proportional, although it has a consistent slope, it does now go through the point of origin or (0,0). The equation of a proportional line is y=kx, so the y-intercept must be at (0,0).
B. Slope is found by , from 1 point to the next, the y-value (rise) increases by 2 and the x-value (run) increases by 1,
giving us a slope of 4.
C. The y-intercept is the lines point of intersection with the y-axis. In the graph, this point is (0,10).
D. y = mx + b is the slope-intercept form where m is the slope and b is the y-intercept, the slope (m) is 4 and the y-intercept (b) is 10. y = 4x + 10
E. The equation is not proportional because the b value is 10 rather than 0.
Answer:
The correct option is (B).
Step-by-step explanation:
We need to find the result of substituting for y in the bottom equation.
Equation (1) is :
Equation (2) is :
Put the value of y form equation (1) to equation (2) such that,
It can be seen from the above equation, that option (2) is same as above equation.
Hence, the correct option is (B).
