Answer:

z+7

Step-by-step explanation:

Firstly once you see the word sum it means you will have to add up to get a specific number

For example the sum of 6 and 7 means 6+7 which will give us 13

The sum of z and 7 will z+7,but we observe that z is not a number so we cannot add z+7 but in the case of multiplication that is z×7

It will give us 7z but the case of addition is totally different from that of multiplication

Therefore the final answer is z+7

What is the equation of a line that passes through (7,8) and has a slope of -3

Komok [63]

It is helpful to first plug this in to point-slope form (note that there are other ways to do this).

Using the form $y-y_1 = m(x-x_1)$ , you get $y-8=-3(x-7)$ . You can simplify this to get $y = -3x+29$ .

Prove the quotient rule. hint: you can do this directly, but it may be easier to find the derivative of 1/x and then use the cha

Bess [88]

The quotient rule is
d(u/v) = (u dv - v du) / u2

d(u/v) can written as
d( u (1/v) )

Using the product rule and chain rule
d( u (1/v)) = u d(1/v) + (1/v) du
= u (-1/v2) dv + (!/v) du
= (u dv - v du) / u2
