Answer:

4

Step-by-step explanation:

→ We go up the y axis to 6 and read of the x coordinate which is 4. This is because an inverse function does the the opposite i.e.  if f ( x ) = y

f⁻¹ ( y ) = x.

Point G is the midpoint of PQ. <br> PG equals 2X plus 3 and GQ equals 5X -5. what is X?
borishaifa [10]

Answer:

x=\frac{8}{3}=2\frac{2}{3}\approx{2.667}

Step-by-step explanation:

\overline{PG}=2x+3\\\overline{GQ}=5x-5

Since they're equidistant (equal distances), we can set them equal to one another and solve for x:

2x+3=5x-5

Adding 5 to both sides:

2x+8=5x

Subtracting 2x from both sides:

8=3x

Dividing both sides by 3:

\frac{8}{3}=x

Therefore:

x=\frac{8}{3}=2\frac{2}{3}\approx{2.667}

If a projectile is modeled by a parabola, what could the x-intercepts represent?
Mars2501 [29]

Answer: The x-intercepts represents the points at which the parabola crosses the axis of x.

Step-by-step explanation:

If it exist then the x-intercepts represent the zeros,  roots, or quadratic function, the values of x at  y = 0. Then the  parabola does not cross the x-axis, so it has no zeros.
