Answer:

The vertex is at (-3/2, 33/4)

x=-3/2

Step-by-step explanation:

y= -x^2 -3x+6

Factor out a negative from the first two terms

y = -(x^2 +3x)  +6

Complete the square

Take 3 /2  and square it  (3/2)^2  = 9/4

The - on the outside of the parentheses means we really are subtracting it so we need to add it on the outside

y = -(x^2 + 3x + 9/4) +9/4 +6

  = -(x+3/2)^2 + 9/4 +6

Get a common denominator of 4

  = -(x+3/2)^2 + 9/4 +6*4/4

y =- (x+3/2)^2 + 9/4 +24/4

y = -(x+3/2)^2 + 33/4

y = a(x-h)^2 +k  where (h,k) is the vertex

y = -(x - -3/2)^2 + 33/4

The vertex is at (-3/2, 33/4)

The axis of symmetry is at the x coordinate of the vertex

x=-3/2

HELP ASAP plz, 45 pts
torisob [31]

Answer:

She didn't take the LCM, made an error while cross multiplying

x = -6

Step-by-step explanation:

a)she didn't take the LCM before cross multiplying.

Also, didn't cross multiply correctly

b) 1 -2/(x-2) = (x+1)/(x+2)

1 - 2/(x-2) = (x+2-1)/(x+2)

1 - 2/(x-2) = 1 - 1/(x+2)

1 - 2/(x-2) = 1 - 1/(x+2)

-2(x+2) = -1(x-2)

-2x-4 = -x+2

x = -6

Please answer this without making mistakes
den301095 [7]

Answer:

1 pound = 16 ounces

2 pounds = 32 ounces

Given:

Cost for 2 pounds of bananas = $1.28

Price per ounce = 1.28/32    [∵2 pounds = 32 ounces]

=$0.04

Hence the cost of bananas per ounce is $0.04

Hope it helped!

Solve the equality, - (7c-18)-2c&gt;0
Gwar [14]
(7c-18)-2c>0

group like terms: 7c-2c-18>0

add similar elements: 7c-2c=5c
5c-18+18>0+18

Add 18 to both sides
5c-18+18>0+18

simplify
5c>18

divide both sides by 5
5c÷5>18/5

simplify
c>18/5
