Answer:

x = 8.17

Step-by-step explanation:

We will be using pythagoras theorem:

a^{2} + b^{2} = c^{2}

=> 4.25^{2} + x^{2} = 9.21^{2}

=> x^{2} = 84.8241 - 18.0625 = 66.7616

=> x = \sqrt{66.7616} = 8.17077719.. = 8.17 (3 s.f)

A graph of a linear function is shown on the grid. Which of these best represents 0 of the function? A 8. B 10. C 16. D 24.
harina [27]

answer:

C. 16

explanation:

when x is 0, the y-intercept is 8

coordinates: (0,8) and (4,6)

slope:

\sf \frac{y2-y1}{x2-x1}

\sf \frac{6-8}{4-0}

\sf \frac{-2}{4}

\sf -\frac{1}{2}

equation:

\sf y = mx +b    [ where m is slope and b is y-intercept ]

y = \sf -\frac{1}{2}x +8

solve for x-intercept:

note: zeros of a function are the values of x when f(x) is equal to 0

y = \sf -\frac{1}{2}x +8

0= \sf -\frac{1}{2}x +8

-8= \sf -\frac{1}{2}x

\sf x = -8 * -2

\sf x = 16
