Answer:

y+1=2(x+3)

Step-by-step explanation:

we know that

The equation of a line in point slope form is equal to

y-y1=m(x-x1)

we have

m=2\\(x1,y1)=(-3,-1)

Heather Johnson bought a new set of tires for $436.00 and a car seat for $22.85. The state tax rate is 6%, the county tax rate i
Papessa [141]

Answer:

$495.56

Step-by-step explanation:

Tax increases the price paid for a good or service. So, the total price paid for the goods would increase by the total amount of tax

Sum of the three taxes = 6% + 1.5% + 0.5% = 8%

Total cost of items purchased = $436 + $22.85 = $485.85

Total purchase price = Total cost of items purchased x (1 + total tax)

$485.85 x (1.08) = $495.56

White raven [17]
The greatest common factor of the numbers is that which is the fused factors of all the numbers without the repetition of the common factors present in the given.
                          25·5·11 = 5·5·5·11
                          23·52·7 =23·2·2·13·7
Since, there are no repeated factors, the answer would be,
                                        5·5·5·11·23·2·2·13·7
The answer unfortunately is not among the choices.
