Answer:

C. Fernando incorrectly found the product of -2 and -5.

Step-by-step explanation:

We have been given an image, which represents work of Fernando's evaluation of an expression. We are  asked to find the error in Fernando's work.

\frac{5(9-5)}{2}+(-2)(-5)+(-3)^2

Let us evaluate our given expression using order of operations (PEMDAS).

\frac{5(4)}{2}+(-2*-5)+9

\frac{20}{2}+10+9

10+10+9

29

Since we know that product of two negative numbers is always positive, therefore, the product of negative 2 and negative 5 will be positive 10.

Therefore, Fernando incorrectly found the product of -2 and -5 and option C is the correct choice.

Use the slope and y intercept to graph y=-3x+1
pashok25 [27]

9the equation of a line in ' slope- intercept form ' is

y = mx + c ( m is the slope and c the y-intercept )

y = 3x + 1 is in this form

with slope = 3 and y-intercept = 1

the graph crosses the y- axis at ( 0, 1 )

from this point moving 3 units vertically up and 1 unit horizontally right gives the point (1, 4 ) . Repeating this gives the point  (2, 7 )

Plot the points (0, 1 ), (1, 4 ) and (2, 7 )

Draw a straight line through them for graph of y = 3x + 1

I'm really having trouble with this one. It says: Use your graphing calculator to find the value of f'(0) for f(x) = sin(x) + e^
lisov135 [29]

Step-by-step explanation:

f'(x) = d/dx [f(x)]

= d/dx (sinx + e^x) = cosx + e^x.

Therefore f'(0) = cos(0) + e^(0) = 2.
