Xintercept for the quadratic function f(x)=x²-8x

Mathematics
2 answers:
vodomira [7]3 years ago

Answer:

x=0 and x=8

Step-by-step explanation:

The x-intercept is on the x-axis, so we must find x when y=0. f(x) is basically y and y=0, so 0=x^2-8x= x(x-8). For x(x-8) to equal  0, either x is equal to 0 (x=0) or x-8 is equal to 0 (so x is equal to 8). So the two intercepts are x = 0 and x = 8.

I hope this helped! :)

The x intercept would be zero since every number is paired with an x value

What number is 32.5% of 38.4
vodomira [7]
38.4/x=100/32.5
multiple both sides of the equation by x
38.4=3.07692307692*x
divide both sides by the big number to get x
38.4/(big number)=x
x=12.48

In the figure below, quadrilateral EFHJ is a parallelogram, and triangle FGH is a scalene right triangle.
DiKsa [7]

Answer:

A

Step-by-step explanation:

In a parallelogram the opposite angles are congruent, thus

∠ JHF = ∠ JEF = 142°

∠ JHF and ∠ FHG are adjacent angles and are supplementary, thus

∠ FHG = 180° - 142° = 38°

The sum of the 3 angles in a triangle = 180° , thus

∠ HFG = 180° - (90 + 38)° = 180° - 128° = 52° → A
