Solve the equation:

– 3b – (– 2) = 4b <span>– 12

</span>– 3b + 2 = 4b – 12

– 3b = 4b – 12 – 2

– 3b = 4b – 14

– 3b – 4b = – 14

– 7b = – 14

        – 14
b = ———
         – 7


b = 2   <———   solution.


I hope this helps. =)

-3(b) - (-2) - (4(b)) which is equal the number 0 
-7(b) + 14
Now, lets solve → -7 = 0 
b - 2 = 0 
Next, we add the number 2 to each of the sides of your problem 
Therefore, the result of b is 2

Two wires are attached 6 feet up a tree and 3 feet from the base of the tree. About how much TOTAL wire was used?
nalin [4]

Answer:

9 cm²

Step-by-step explanation:

Two wires are attached 6 feet up a tree and 3 feet from the base of the tree. About how much TOTAL wire was used?

We solve the above question, using the Area of a Triangle

Area = 1/2 × Base × Height

Area = 1/2 × 3 × 6

Area = 9 cm²

Therefore, the total wore that was used was 9cm² of wire

How do you do this question?
Step2247 [10]

Answer:

D

Step-by-step explanation:

f(x)=(x-1)(x^2+2)^3\\f'(x)=(x-1)*3(x^2+2)^2*2x+(x^2+2)^3*1\\f'(x)=6x(x-1)(x^2+2)^2+(x^2+2)^3\\f'(x)=(x^2+2)^2[6x^2-6x+x^2+2]\\f'(x)=(x^2+2)^2(7x^2-6x+2)\\D

pychu [463]
Sid and Libby are planning to sell pies at a local fair.
=> $200 to rent a table at the fair.<span>
=>  $3.00 per pie </span>costs for ingredients, other supplies, baking, and packaging<span>
They plan to sell the pies for $8 each. 
Let's find out how many pies will they be selling inorder to gain profit
=> 200 + 3.00(n) = 8(n), where n is the number of pie.
Let's try 40
=> 200 + 3(40) = 8 (40)
=> 320 = 320 
</span>=> 200 + 3(41) = 8 (41)
=> 323 = 328
<span>Thus, in their 41st pie, they will get a profit

Help please i don’t know how to do it
nekit [7.7K]

Answer:

x + 3y = 15

Step-by-step explanation:

Line is passing through the points (3, \:4) = (x_1,\:y_1)\:and\: (9, 2)=(x_2,\:y_2)

Slope of line (m)= (2 - 4)/(9 - 3) = -2/6 = -1/3

Equation of line in point-slope form is given as:

y-y_1 =m(x-x_1)

Plugging the values of x_1,\: y_1\: and \: m in the above equation we find:

y-4 =-\frac{1}{3}(x-3)

\implies 3y-12 =-x+3

\implies x+ 3y =12+3

\implies \huge {\orange{\boxed{x+ 3y = 15}}}

This is the required equation of line in the form \red{\bold{ax + by = c}}
