80 = 3y+ 2y+4+1
Simplfy like terms:
80 = 5y + 5
-5 -5
75 = 5y
5 5
y = 15
The answer is A. hope this helps

$3y + 2y = 5y \\ 4 + 1 = 5 \\ 80 = 5y + 5 \\ 80 - 5 = 75 \\ 75 \div 5y = 15 \\ y = 15$

Find the properties of the parabola with the equation (x + 5) 2 = 4(y - 1)

Tanya [424]

Answer:

Option a. (-5, 2)

Step-by-step explanation:

The focus of a parabola is a point. Regarding this point, each point of the parabola has the same distance to a line that is known as "directrix".

By definition, for a parabola of the form:

$(x-h)^2 = 4p(y-k)$

The focus of the parable is given by the point: (h, k +p)

We must identify the values of h, k and p for the given equation.

$(x + 5)^2 = 4(y - 1)$

$h = -5\\k = 1\\4p = 4\\p =1$

Now that we know the values of h, k and p we can find the focus

The focus is

(-5, 1+1)

(-5, 2).

Find the GCF of the given polynomial. 8x6y5 - 3x8y3

Whitepunk [10]

The GCF of this polynomial is x^6y^3.
8x^6y^5 - 3x^8y^3 = x^6y^3 (8y^2 - 3x^2)

This polynomial cannot be factorized any further. Hope this helps!

Jessica has 48 coins, some of them are nickels and some are dimes. How many of each does she have if she has $3.25 total? 69 POI

Mrrafil [7]

Answer:

Nickels = 44.6

Dimes = 3.4

Step-by-step explanation:

We know that Jessica has 48 coins of which some are nickels and some are dimes so we can write it as:

n = amount of nickels

d = amount of dimes

$n+d=48$ --- (1)

We are to find the number of nickels and dimes if their total worth is $3.25.

Since a dime is worth 10¢ and a nickel is 5¢, so it should be:

$0.05n + 0.3d = 3.25$ --- (2)

From (1):

$n=48-d$

Substituting this value of $n$ in (2) to get:

$0.05(48-d) + 0.3d = 3.25$

$2.4-0.05d+0.3d=3.25$

$2.4+0.25d=3.25$

$0.25d=0.85$

$d=3.4$

Finding $n$ by substituting the value of $d$ :

$n=48-d$

$n=48-3.4$

$n=44.6$
