(I work better with decimals so I'm turning these fractions into decimals)
2/3 = 0.6
1/4 = 0.25
4/9 = 0.4
Okay so
0.6 - 0.25 = 0.35

0.35 x 0.4 = 0.14

And 0.14 into a fraction is 7/50

The answer is 7/50 Which is it's simplest form.

Let's use PEMDAS for this expression (parentheses, exponent, multiplication/division, addition/subtraction) Even though subtraction is first, you would multiply first because multiplication is before subtraction So multiply -(1/4) and (4/9) and you get -(1/9). Now add (2/3) and you get a final answer of (5/9)

The function f(x)=-(x+5)(x+1) is shown. What is the range of the function?

Vesna [10]

Answer:

(- ∞, 4 ]

Step-by-step explanation:

To determine the range we require the coordinates of the vertex

The vertex lies on the axis of symmetry which is positioned at the midpoint of the zeros.

To obtain the zeros, equate f(x) to zero, that is

-(x + 5)(x + 1) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x + 1 = 0 ⇒ x = - 1

$x_{vertex}$ = $\frac{-5-1}{2}$ = $\frac{-6}{2}$ = - 3

Substitute x = - 3 into f(x) for corresponding value of y

f(- 3) = - (- 3 + 5)(- 3 + 1) = - (2)(- 2) = 4

Vertex = (- 3, 4)

Since a = - 1 then vertex is a maximum, hence

range is (- ∞, 4 ]

Plz helppp meee wallah I swear to god I will mark you as a brainliest and I will give you 20

givi [52]

Answer:

Step-by-step explanation:

Equation for the linear function has been given as,

y = 26 - 4x

For x = 1,

y = 26 - 4(1)

= 26 - 4

= 22

For x = 2,

y = 26 - 4(2)

= 26 - 8

= 18

For x = 3,

y = 26 - 4(3)

= 26 - 12

= 14

For x = 6,

y = 26 - 4(6)

= 26 - 24

= 2

Therefore, table for the function will be,

x y

1 22

2 18

3 14

Mr. Yueng graded his students’ math quizzes.

Artyom0805 [142]

For this case we must solve the following equation:

$x ^ 3 = 22$

If we apply cubic root to both sides of the equation, then we eliminate the exponent on the left side:

$\sqrt [3] {x ^ 3} = \sqrt [3] {22}\\x = \sqrt [3] {22}$

That is the exact solution of the equation. Its decimal solution is given by:

$x = \sqrt [3] {22} = 2.8020$

ANswer:

The solution to the equation is $x = \sqrt [3] {22} = 2.8020$
