Which is a zero of the quadratic function f(x)=9x^2-54x-19?
Arturiano [62]
A zero, or a solution of the quadratic function is c) x = 6 1/3


Write -54x as a difference
9x^2 + 3x - 57x - 19

Factor 3x out
{ 9x^2 + 3x }  - 57x - 19
3x (3x + 1)

Factor -19 out
3x (3x + 1) -19 (3x + 1)

Group the equations
( 3x - 19 ) ( 3x + 1 )

Solve for the zeroes

(3x+1) = 0
     -1     -1
3x = -1
3x / 3 = x
-1 / 3 = -1/3
x = - 1/3

(3x - 19) = 0
      +19   +19
3x = 19
3x / 3 = x
19 / 3 = 6 1/3
x = 6   1/3

A language arts test is worth 100 points. There is a total of 26 questions. There are spelling word questions thatare worth 2 po
Ostrovityanka [42]

Answer:

Spelling word questions = 10

vocabulary word questions = 16

Step-by-step explanation:

Let

Spelling word questions = x

vocabulary word questions = y

Total points = 100

Total questions = 26

x + y = 26 (1)

2x + 5y = 100 (2)

From (1)

x = 26 - y

Substitute x = 26 - y into

2x + 5y = 100

2(26 - y) + 5y = 100

52 - 2y + 5y = 100

- 2y + 5y = 100 - 52

3y = 48

y = 48 / 3

= 16

y = 16

Substitute y = 16 into

x + y = 26

x + 16 = 26

x = 26 - 16

= 10

x = 10

Spelling word questions = 10

vocabulary word questions = 16

Find the areas of the two individual rectangles and then add that up to find the area of the figure:

Rectangle A:                                                             Rectangle B:

= Length * Width                                                       = 11.5 * 3

= 7.5 * 3                                                                     = 34.5ft²

= 22.5 ft²

Area of figure:

What is X?<br><br> 2.3x-8.7=0.8x-4.2<br><br> pLS hELP
daser333 [38]

Answer:

x = 45/17

Step-by-step explanation:

We can move all x to 1 side and all the numbers to another. You can add 8.7 on both sides and get that 2.3x = 0.8x + 4.5. Next, we subtract by 0.8x on both sides to get that 1.7x = 4.5, where we can then divide by 17/10 on both sides to get that x is equal to 45/10 * 10/17, so that means that x = 45/17.
