I am pretty sure that the answer is A. because the slopes are reciprocals of each other, and so they are perpendicular

The cost (in dollars) of making b bracelets is represented by 4 5b. The cost (in dollars) of making b necklaces is represented b

Leviafan [203]

Answer:

$(3b+2)

Step-by-step explanation:

The cost of making b bracelets = 4+5b

The cost of making b necklaces = 8b+6.

To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.

Extra Cost = Cost of b Necklaces-Cost of b Bracelets

=(8b+6)-(4+5b)

open the brackets

=8b+6-4-5b

Collect like terms

=8b-5b+6-4

=3b+2

It costs $(3b+2) more to make b necklaces than b bracelets.

Answer:

The value of x will be:

$x=-5$

Step-by-step explanation:

Given the equation

$4-2(x+7)=3(x+5)$

Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.

$4-2x-14=3x+15$

simplifying the equation by subtracting 14 from the L.H.S

$-10-2x=3x+15$

Subtracting 15 from both sides

$-10-2x-15=3x+15-15$

$-25-2x=3x$

combining the like terms

$-25=3x+2x$

$-25=5x$

dividing both sides of the equation by 5

$\frac{-25}{5}\:=\:\frac{5x}{5}$

$-5=x$

Therefore, the value of x will be:

$x=-5$
