Correct answer is option D.

The solution is listed below

F(x)=4x+7 \\  \\ 
y=4x+7 \\  \\ 
y-7=4x \\  \\ 
 \frac{y-7}{4}=x \\  \\ 
 x= \frac{y-7}{4} \\  \\ 
f-^{1}(y) = \frac{y-7}{4} \\  \\ 
f-^{1}(x) = \frac{x-7}{4} \\  \\

Schach [20]

Answer:

The original Slope is y=-1/3x-2

The perpendicular slope would be y=3x+b

Step-by-step explanation:

Original Slope:

You already have the y-interecpet, (0,-2), and you know two points (0,-2) and (-6,0), so you can find the slope with (y1-y2)/(x1-x2) so in this case, it would be (0-(-2))/(-6-0)= -1/3 and you can find y=1/3x-2.

Perpendicular Slope:

The slope of any perpendicular line would be the reciprocal of the original. So the reciprocal of -1/3 is 3. The b can be any real number because no matter the y-intercept the slope would still be perpendicular

Please help me I am really confused.
Feliz [49]

Answer:

f(96) = 85

Step-by-step explanation:

f'(95) gives us the slop of 6, which can be used to estimate the increase

of the next number.

Ex) f(95) = 79 & f'(95) = 6 so

     f(96) = 79 + 6 = 85

mr yosgi has 75 papers he graded 60 of them and let a student grade the rest what percent if the papers did each person grade?
Alika [10]


He graded 60/75 papers.

If you divide these numbers instead of trying to simplify it equals the decimal 0.8.

If you move the decimal point two places to the right it's 80%.
