Answer:

(-1,0), (3,0)

Step-by-step explanation:

(x+1)(x-3) = y

We are trying to find the values for x which make y = 0.

y can only equal 0 when x+1 or x-3 =0

When you solve both x+1 =0, and x-3=0, your solution set is x = -1,3 --> (-1,0), (3,0)

Oksanka [162]

Let
C---------> the cost of a pizza
t----------> number of toppings

we know that
$15.74-3t=$14.49-2t
15.74-14.49=3t-2t-------------> t=1.25

the cost of one topping is $1.25
and the cost of one pizza without topping is
15.74-3*1.25--------> $11.99

then
an equation for the cost of a pizza, C, as a function of the number of toppings, t ordered is
C=11.99+1.25t

the answer is
C=11.99+1.25t

Naily [24]

The answer is 14 bolts.

1 dozen bolts have 12 bolts.

x = 84 bolts

1 bin has 7-dozen bolts (84 bolts).
1/6 bin has x bolts

1 : 84 = 1/6 : x
x = 84 * 1/6 : 1
x = 84/6 = 14 bolts
