Answer: 8 3/4

Step-by-step explanation:

3x(4x-5+3); where x is 1/2

Substitute the value 1/2 with x

3 1/2 (4 1/2 - 5+3)

7/2 (9/2 -2)

7/2 (5/2)

35/4 = 8 3/4

13. It takes Seymore, a slimy slug, 20 minutes to travel from his favorite bush to the local trash can (a distance of 30 meters)
Serjik [45]

Answer:

90 meters

Step-by-step explanation:

From the question we are to calculate the distance that the slug can move in 60 minutes.

From the question, we know that:

20 minutes = 30 meters

60 minutes = x meters

Cross Multiply

20 minutes × x meters = 30 meters × 60 minutes

x meters = 30 meters × 60 minutes/20 minutes

x meters = 90 meters

How to find vertex form
Nikolay [14]
Y = x^2 - 6x + 7
a = 1
b = -6
c = 7

Before you get the A.O.S, you must first solve for the vertex.
The vertex formula is \frac{-b}{2a} 

Plug in the numbers:
-(-6) / 2(1)
--6 = 6 and 2*1 = 2
6/2
Vertex (or x) = 3

Now you have to plug in the x in order to find the vertex (or y)
Your equation should now look like this;
y = (3)^2 - 6 (3) +7
Solve each part separately and then add it up...

3^2 = 9
-6 * 3 = -18
+7

9 - 18 + 7
A.O.S (or y) = -2
