Step-by-step explanation:

Answer: f(3) = - 28

Step-by-step explanation:

f(x) = - 4x² + 4x - 4

f(3) = - 4(3)² + 4(3) - 4            [We are solve for f(3), where x is equal to 3, we plug 3 for the x]

f(3) = - 36 + 12 - 4

f(3) = - 24 - 4

f(3) = - 28

Answer:

3.9x+0.8y

Step-by-step explanation:

4x−5.2y+6y+7.9x−8x

Combine −5.2y and 6y to get 0.8y.

4x+0.8y+7.9x−8x

Combine 4x and 7.9x to get 11.9x.

11.9x+0.8y−8x

Combine 11.9x and −8x to get 3.9x.

3.9x+0.8y

It can also be converted to fraction form:

[tex]\frac{4y}{5}+\frac{39x}{10} = 3.9x+0.8y[/tex]

Answer:x-intercepts (0,2) ; (0,3)

Step-by-step explanation:

x^2 - 5x + 6 =0

(x-2)(x-3) = 0            

[-2 and -3 was the factors of 6, which make them equal to -5 when them add].

x-2=0            x-3=0

   x=2               x=3

so x-intercepts (0,2) ; (0,3)

Answer:

-2 and 18 is the answer

Step-by-step explanation:

Answer:

It differs by 4

16 - 12  =  4

 4  =  4

Their product is 192

(16) (12)  =  192

192  =  192

Step-by-step explanation: The sum of two numbers is 60 and their product is 576. Find the numbers. Let x and y are the two consecutive integers

The sum of two numbers is 60

x + y  =  60  ---- (1)

Product of two numbers  =  576

xy  =  576

y  =  576/x  ----- (2)

Now we apply the value of x in (1)

x + (576/x)  =  60

(x2 + 576) / x  =  60  

x2 + 576  =  60x

x2 - 60x + 576  =  0

(x - 12) (x - 48)  =  0

x - 12  =  0

x  =  12

If x  =  12

y  =  576 / 12

y  =  48

x - 48  =  0

x  =  48

If x  =  48

y  =  576 / 48

y  =  12

So the required integers are 18 and The sum of two numbers is 60

48 + 18  =  60

60  =  60

The product is 576

48 (18)  =  576

576  =  57648.

Two positive numbers differ by 4 and their product is 192. Find the numbers.

Let x and y be two positive numbers

It differs by 4

x - y  =  4

x  =  4 + y   --- (1)

Their product is 192

xy  =  192

y  =  192/x --- (2)

By applying the value of y in (1), we get

x  =  4 + (192/x)

x  =  (4x + 192)/x

x2  =  4x + 192

x2 - 4 x - 192  =  0

(x - 16) (x + 12)  =  0

x - 16  =  0

x  =  16

x + 12  =  0

x  =  -12

If x  =  16

Then,

y  =  192/16

y  =  12

Since it is positive number we have to choose 16 for x.

Answer:

x = 20

Step-by-step explanation:

The sum of the two angles is 90 degrees

x+3x+10 = 90

Combine like terms

4x+10 = 90

Subtract 10 from each side

4x+10-10 = 90-10

4x= 80

Divide each side by 4

4x/4 = 80/4

x = 20

Answer:

x = 20

Step-by-step explanation:

x and 3x + 10 form a right angle, then

x + 3x + 10 = 90

4x + 10 = 90 ( subtract 10 from both sides )

4x = 80 ( divide both sides by 4 )

x = 20

Answer:

Number of students who got grade A = [tex]\frac{8y}{x}[/tex]

Step-by-step explanation:

Number of students who got grade B = 8

Ratio of the students that got A to the students who got B = [tex]y:x[/tex]

That is

Number of students who got grade A : Number of students who got grade B =  

[tex]y:x[/tex]

Number of students who got grade A : 8 = [tex]y:x[/tex]

Therefore,

Number of students who got grade A = [tex]\frac{8y}{x}[/tex]

Answer:

90

Step-by-step explanation:

Partition the figure by extending the sides of the ``middle'' square as shown at the right. Each original square contains four $3 \times 3$ small squares. The shaded figure consists of ten $3 \times 3$ squares, so its area is $10 \times 9 = \boxed{90\text{ square

units}}$.

In this exercise we have to use the knowledge of areas to calculate the area of ​​the square in gray, so we have that:

[tex]A=90[/tex]

First it is informed that one side of the square is 6, so every square has exactly:

[tex]l^2=6^2=36[/tex]

Adding that we have 3 squares with the same value of sides:

[tex]36*3=108[/tex]

However, there are areas that are being calculated twice in the central square, these areas are smaller squares that have side values ​​equal to 3, so:

[tex]l^2=3^2=9\\9*2=18\\108-18=90[/tex]

Answer:

It's A)

X-9 _< 2(9-x)

X-9 _< 18 - 2x

X+2x _< 18+9

3x _< 27

x _< 27/3

x _< 9

Answer:

A

Step-by-step explanation:

Given

x - 9 ≤ 2(9 - x) ← distribute parenthesis

x - 9 ≤ 18 - 2x ( add 2x to both sides )

3x - 9 ≤ 18 ( add 9 to both sides )

3x ≤ 27 ( divide both sides by 3 )

x ≤ 9 → A
