Answer: -3^2+13x-5

Step-by-step explanation:

Remove parentheses.

3x^2+7x -4 - 6x^2 +6x -1

Collect like terms.

(3x^2-6x^2) + ( 7x + 6x) + ( -4 -1)

Simplify

-3^2+13x-5

if a unit price label has a unit price of 15.5 cents per ounce how much is the total price for 24 ounce package?
anyanavicka [17]
Multiply cents by ounces
15.5 cents * 24 ounces= 372 cents

Change to dollars. Divide by 100 cents in a dollar
372 cents ÷ 100 cents in a dollar= $3.72

The total price is $3.72

The coordinates of the vertices of △JKL are J(3, 4), K(3, 1) , and L(1, 1) . The coordinates of the vertices of △J′K′L′ are J′(−
timurjin [86]

The <em><u>correct answer</u></em> is:

A 180° rotation followed by a translation 1 unit down.

Explanation:

The points are mapped as follows:

J(3, 4)→J'(-3, -5)

K(3, 1)→K'(-3, -2)

L(1, 1)→L'(-1, -2)

A 180° rotation maps a point (x, y) to (-x, -y).  This would map

J(3, 4)→(-3, -4)

K(3, 1)→(-3, -1)

L(1, 1)→(-1, -1)

The difference between these points and the image points are that each y-coordinate of the image is 1 lower than these.  This means a translation 1 unit down would result in the image points.

Crank

Answer:

50

Step-by-step explanation:

Let a = number of balls in bag A.

a = 1.2b

a - 5 = b + 5

1.2b - 5 = b + 5

0.2b = 10

b = 50
