Estimate 72.91 + 67.526 by first rounding each number to the nearest whole number

Vikentia [17]

Answer:

141

Step-by-step explanation:

First, you would round 72.91 to 73 because the number to the right of 7 is greater than or equal to 5, so you would round up. Same goes for 67.526. round both up to 73 and 68 then add. You would get an answer of 141 :)

Solving for Y

3x+y=2

y=2-3x

y=2-3x,x R

Solving for X

3x+y=2

3x=2-y

x= 2/3-1/3y

x=2/3-1/3y

Find the x-intercept

3x+y=2

3x+0=2

3x=2

x=2/3

Find the y-intercept

3x+y=2

3 times 0+y=2

F(x) = 1/(5x-6)Find the derivative of this function

siniylev [52]

Given

$f(x)=\frac{1}{5x-6}$

To find the derivative of the give function,we apply below exponent rule first:

$\frac{1}{a}=a^{-1}$

So,

Next, we apply the chain rule:

So,

We substitute back u=(5x-6):

Simplify:

Therefore, the answer is:

$=-\frac{5}{(5x-6)^2}$
