Do you have the whole question? The problem that you gave does not have a problem....

Answer:

f(-9) = -189

Step-by-step explanation:

f(x) = -3x² - 6x

Plug in -9 for x.

f(-9) = -3(-9)² - 6(-9)

According to PEMDAS (parentheses/exponents | multiplication/division | addition/ subtraction), we should solve the exponents first.

f(-9) = -3(81) - 6(-9)

Now, multiply.

f(-9) = -243 + 54

Now, add.

f(-9) = -189

This is your answer.

Answer:

Original price of the game = $27

Step-by-step explanation:

Let

Original price of the game = x

x - 1/3x = 18

(3x-x)/3 = 18

2/3x = 18

x = 18 ÷ 2/3

= 18 × 3/2

= (18*3)/2

= 54 / 2

= 27

x = $27

Original price of the game = $27

Answer: x = -5 (rewritten: x + 5 = 0)

Step-by-step explanation:

First, we must take into account that the line is parallel to the y-axis. If a line is parallel to the y-axis, it is vertical, meaning that for every y-value, there can only be one x-value. Since the question contains a point that the line passes through, which is (-5, 2), we know that for every y-value of the line, the x-value will always equal -5. Thus, the equation of the line must be x = -5 (or, rewritten, x + 5 = 0).

Answer: $ 6160

Step-by-step explanation:

Total money he will pay back = Principal + Interest

Simple interest = Principal x Rate x Time

i.e. Total amount need to pay = Principal + (Principal x Rate x Time)

= Principal (1+ Rate x Time)

Given: Principal =  $5,500, Rate = 3%=0.03 , Time = 4 years

Total amount need to pay = [tex]5500(1+(0.03)(4))[/tex]

[tex]= 5500(1+0.12)\\= 5500(1.12)\\=\$6160[/tex]

Hence,  the total amount he will have to pay back to the bank = $ 6160

ju12. Julle is looking through a catalogue for ice-cream. She can buy 2 L of triple-chocolate

Step-by-step explanation:

Julle is looking through a catalogue for ice-cream. She can buy 2 L of triple-chocolate

ice cream for $6.30 while the vanilla fudge ice-cream is usually $5.40 for 1.2 L.

What saving does there need to be on the price of the 1.2 L container of vanilla fudge

ice cream for it to be of equal value to the 2 L triple-chocolate container?

Answer:

I thinks its 33?

Step-by-step explanation:

It said diagonal, not horizontal. Horizontal is left and right, diagonal is up and down, and since its talking about the screen size it should be 33 inches

Answer:

55

Step-by-step explanation:

I used some graphing software. I changed 33 and 44 to 3 and 4 just for the sake of saving space. So the diagonal measurement is represented by segment BD. So since I divided 33 and 44 by 11 to make it smaller to get 3 and 4, I am going to multiply 5 by 11 to get 55

Thus the REAL diagonal measurement of the TV screen is 55 inches

Answer:

y = - [tex]\frac{3}{4}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = [tex]\frac{0-3}{4-0}[/tex] = - [tex]\frac{3}{4}[/tex]

The line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = - [tex]\frac{3}{4}[/tex] x + 3 ← equation of line

Answer:

x=10

Step-by-step explanation:

Simplifying

1.5x + 3 = 18

Reorder the terms:

3 + 1.5x = 18

Solving

3 + 1.5x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 1.5x = 18 + -3

Combine like terms: 3 + -3 = 0

0 + 1.5x = 18 + -3

1.5x = 18 + -3

Combine like terms: 18 + -3 = 15

1.5x = 15

Divide each side by '1.5'.

x = 10

Simplifying

x = 10

p³r² - (m + np)

m = -32

n = 2

p = -8

r = 4

(i assume the 3 and 2 are supposed to be squared and cubed symbols)

substitution:

-8³ · 4² - (-32 +2 · -8)

-512 · 16 - (-32 -16)

-8192 + 48

-8144 should be the answer if the portion in "p3r2" is meant to be squared and cubed symbols

Hope this helped! :D

The value of the expression p³r² − (m + np) is -8144 after plugging the values of m=−32, n=2, p=−8, and r=4.

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The expression is:

= p³r² − (m + np)

Plug m = -32, n = 2, p = -8, and r = 4 in the expression:

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

= (-8)³(4)² − (-32 + 2(-8))

= -8192 + 48

= -8144

Thus, the value of the expression p³r² − (m + np) is -8144 after plugging the values of m=−32 , n=2 , p=−8 , and r=4.

Answer:

x+y=30 and x-y=8. Angel is 11 and Alex is 19

Step-by-step explanation:

30÷2=15

8÷2=4

15-4=11

15+4=19

19+11=30

Consecutive even numbers are numbers that go in order, such as 1,2,3,4,5.

There are 5 even numbers.

They would be x, x+2, x+4, x+6, and x+8 (you add 2 each time so they are even).

Now when adding all these numbers, you get 100.

So there's your equation.

x+x+2+x+4+x+6+x+8=100

Add like terms.

5x+20=100

Solve for x.

5x=80

x=16

So the first number is 16.

The second is 18.

Third is 20.

Fourth, 22.

And fifth, 24.

You can add them to see if you are correct.

16+18+20+22+24=100

The numbers are 16,18,20,22, and 24.

Answer:

s=29

Step-by-step explanation:

==========================================================

Work Shown

Rule: The three interior angles of any triangle always add to 180

(angle1)+(angle2)+(angle3) = 180

(64)+(2s)+(2s) = 180

4s+64 = 180

4s+64-64 = 180-64 ..... subtracting 64 from both sides

4s = 116

4s/4 = 116/4 ............ dividing both sides by 4

s = 29
