Evarado paid $1.12 for a dozen eggs at his local grocery store.  Determine the cost of 3 eggs
Anton [14]
First you have to find out the cost for a single egg.

Since there are a dozen (12) eggs, you can divide the total cost by that.
1.12/12 ≈ 0.09.

Using the base cost of an egg, you can find out how much 3 eggs would cost.

0.09 x 3 = $0.27

I need help with this ASAP! I will give 25 pts.
Assoli18 [71]

Answer:

hope this helps!

Step-by-step explanation:

From y(t) = −16t^2 − 3t + 300 find at what time the fertilizer hits the ground (has height 0)

0 = −16t^2 − 3t + 300

Using the quadratic formula (minus b plus or minus the square root of b squared minus 2 a c over 2 a) you get

t = 4.237 seconds

So the horizontal distance is 85t = 85 * 4.237 = 360.145 feet

How do you factor this trinomial? :
Nezavi [6.7K]
The pic is blurry, but looks like 18x²-21x-15
(3x-5)(6x+3) is the factored form. 
3 and 6 are the factors of 18
-5, 3 or -3, 5 are the factors of -15
I line them up like this
3   -5
6    3
then I multiple them diagonally: 3*3=9, -5*6=-30, the sum of 9 and -30 is exactly -21, the coefficient for x. (If the sum doesn't make -21, I'd switch -5 and 3, or change to -3 and 5 to try again.) 
so the factored form is (3x-5)(6x+3)

Triangle ABC has vertices at A(−3, 4), B(4, −2), C(8, 3). The triangle translates 2 units up and 1 unit right. Which rule repres
Nataly [62]

Answer:

The translation statement is given by:

(x,y)\rightarrow (x+1,y+2)

After the translation, the coordinates of vertex A is (-2,6).

Step-by-step explanation:

Given :

Vertices of a triangle ABC are:

A(−3, 4), B(4, −2), C(8, 3)

The triangle is translated 2 units up and 1 unit right.

To find the co-ordinates of point A after translation.

Translation rules.

For shift of c units up, the translation is given as:

(x,y)\rightarrow (x,y+c)

For shift of k units right, the translation is given as:

(x,y)\rightarrow (x+k,y)

So, it says the triangles is translated 2 units up and 1 unit right.

The translation statement is given by:

(x,y)\rightarrow (x+1,y+2)

So, co-ordinates of point A after translation is given by :

(-3,4)\rightarrow (-3+1,4+2)=(-2,6)

After the translation, the coordinates of vertex A is (-2,6).
