Answer:
You would have to use the formula
Step-by-step explanation:
You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero. The formula for slope is sometimes referred to as "rise over run", because the fraction onsists of the "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).
4x is substitution and x4 is to multiply. hope that helped
Step-by-step explanation:
B and E
B-2 × 4 × 3) + (2 × 9 × 4)=96
E-3 × 4 × 4) + (6 × 4 × 2)=96
answer correct B and E
The slope and speed of Plane A is 375mph and slope and speed for Plane B is 425 mph... so Plane A travels the fastest
Answer:
Zero real roots:
f(x) = x^2-x+1
f(x) = x^2+2x+3
One real root:
Two real roots:
f(x)=x^2+2x+1
f(x)=x^2-3x+2
Step-by-step explanation:
These were determined by using the quadratic formula.
