Answer:

See below

Step-by-step explanation:

The derivative of the function is the slope

2x^2 - x -1       take derivative  ( f ' )

4x -1                 equate to 7

7 = 4x -1

x = 2        sub into the original equation to find y = 5

Can you walk me through the steps: 3t+2+2t-4t=3+5
neonofarm [45]
To find t? yes.

First, you combine like terms so 3t and 2t and 4t. Add 3 and 2 and then subtract the 4. you will end up with 1t (just t) +2. you cannot add the 2 because it does not have the variable t. on the other side, you will also combine like terms. so 3+5=8. now your equation is t+2=8. this is the part where you will try to get t by itself. subtract the 2 from the left side. but in order for the equation to stay equal to itself, you have to subtract 2 from the right side as well. this will leave you with your final answer of t=6.

PLEASE ANSWER ITS DUE SO SOON
geniusboy [140]

the line is negative because it goes down as you move right

slope = rise/run = 4/2 = 2

y = 2x+b

use a point on the line - I picked (-4, 3)

3 = 2(-4)+b

3 = -8+b

11 = b

<h2>y = 2x +11</h2>

4(5-2x) - 3x ≥ 8x-113

20-4x -3x≥ 8x-113

20-7x≥ 8x-113

20+113≥ 8x+7x

133≥ 15x

15x≤ 133

x≤ 133/15

x≤ 8.86

The book fair had 150 free pencils to give to the 4th grade. If there are twenty- five 4th grade students, how many pencils (p)
ch4aika [34]

Answer:

6 pencils per student

Explanation:

We know that there are 150 pencils and 25 students; therefore to find the number of pencils each student gets, we divide 150 by 25

Hence,

150 pencils / 25 students = 6 pencils / student.

which is our answer!
