G. 4/3

Slope is equal to y2-y1 divided by x2-y1. y2 is -1 and y1 is -13.

-1 - (-13) is equal to -1 + 13. -1 + 13 is equal to 12. So, 12 would be the numerator.

Now we will figure out the denominator. The equation for the denominator is x2 - x1. x2 is 3 and x1 is -6. We should now plug in these points into the equation. 3 - (-6) is simplified to 3 + 6. 3 + 6 is 9 so the denominator is 9.

If the numerator is 12 and the denominator is 9, also written as 12/9, would be simplified to 4/3 (answer choice G).

The answer would be G. To get this do y2-y1/x2-x1. And then simplify.

The maximum value of the function: f(x)= -5 x ^2 +30x-200 is?
VARVARA [1.3K]

Answer:

\displaystyle    - 155

Step-by-step explanation:

we are given a quadratic function

\displaystyle f(x) =  - 5 {x}^{2}  + 30x - 200

we want to figure out the minimum value of the function

to do so we need to figure out the minimum value of x in the case we can consider the following formula:

\displaystyle x _{ \rm  min} =  \frac{ - b}{2a}

the given function is in the standard form i.e

\displaystyle f(x) = a {x}^{2}  + bx + c

so we acquire:

  • b=30
  • a=-5

thus substitute:

\displaystyle x _{ \rm  min} =  \frac{ - 30}{2. - 5}

simplify multiplication:

\displaystyle x _{ \rm  min} =  \frac{ - 30}{ - 10}

simply division:

\displaystyle x _{ \rm  min} =  3

plug in the value of minimum x to the given function:

\displaystyle f (3)=  - 5 {(3)}^{2}  + 30.3 - 200

simplify square:

\displaystyle f (3)=  - 5 {(9)}^{}  + 30.3 - 200

simplify multiplication:

\displaystyle f (3)=  - 45  + 90- 200

simplify:

\displaystyle f (3)=   - 155

hence,

the minimum value of the function is -155
