Step-by-step explanation:

Becuase 81 is greater than 9 and 9 is less than 12 (I hope this helps) :)

Step-by-step explanation:

12 less ( subtracting 12 from something else)

the quotient-Dividing between two values

A number: let's use Y

so we want to substract 12 from the product of y/9

(Y/9) -12.

So 81 is greater than 9 but 9 is less than 12.

Answer:

C. 4 Dollar and 45 cent

Step-by-step explanation:

7.45 subtract 3.00 is 4.45

aka

7.00 subtract 3.00 which is 4.00 and add the 0.45

Answer:

c. I am writing extra stuff to be able to send it lol

Step-by-step explanation:

7 45 - 3 =4. 45

The derivative at x = 3 does not exist.

To see why, recall the definition of absolute value:

[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]

If x - 3 ≥ 0, then

2 + |x - 3| = 2 + (x - 3) = x - 1

and the derivative of this piece is 1 for all x > 3.

If x - 3 < 0, then

2 + |x - 3| = 2 - (x - 3) = 5 - x

and its derivative is -1 for all x < 3.

The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.

Answer:

$2.57

Step-by-step explanation:

Create an equation.

7x + 3 = 21

Subtract 3 from both sides of the equation.

7x = 18

Divide 7 from both sides to find x.

18/7 = x,

x = 2.57

Answer:

C.  Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

Answer:

200

Step-by-step explanation:

You can simply just graph it and see where the points intersect, or you can do it algebraically.

0.45x+29.99=0.40x+39.99 subtract 29.99 both sides

0.45x=0.40x+10.00 subtract .40x both sides

0.05x=10.00 divide both sides by 0.05

x=200

Answer: 6003.2

Step-by-step explanation:

Answer:

m∠1 = 52, m∠2 = 60

Step-by-step explanation:

68 and ∠2 are interior angles. 128 is exterior angle.

Formula : -

Sum of two interior angles = Exterior angle

68 + ∠2 = 128

∠2 = 128 - 68

∠2 = 60

∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,

∠1 + 128 = 180

∠1 = 180 - 128

∠1 = 52

Answer:

BD=5, AB=15

Step-by-step explanation:

Because AB = AC, AC =15, SO AB = 15

Because Δ DAB ≅ Δ DAC, So BD = DC =5

Answer:

Negative 9.5

Step-by-step explanation:

3(0.5 - 2) - 4(2 - 0.75)

3(-1.5) - 4(1.25)

-4.5 - 5

-9.5

Answer:

I believe it is answer b.

Step-by-step explanation:

You multiply 4x and - 7 by 1/5 which gives you 4/5x and 1 2/5. You add 4/5x and 2/5x as they are like terms and get 1 1/5x. The equation then becomes 1 1/5 - 1 2/5

b) -2.133a+6

y=-2x+7

Step-by-step explanation:

line segment xy has endpoints x(5 7) and y(-3 3)

for the equation of the perpendicular bisector of line segment xy

slope of line segment xy = 7-3 / 5+3

= 4/8

=1/2

so slope of perpendicular bisector is -2

as m1m2= -1 or m1= -1/m2

As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy

midpoint(x,y) = (5-3 / 2 , 7+3 / 2)

=(2/2, 10/2)

=(1,5)

find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2

y-5 = -2(x-1)

y-5 =-2x+2

y=-2x+7

Answer:

f(x) = x³ + 19x² + x + 19

Step-by-step explanation:

Zeros: -19 , -i, complex conjugate root: +i

Function: (x+19)(x+i)(x-i) = 0

(x + 19) (x² - i²) = (x + 19) ( x² + 1) = x³ + 19x² + x + 19

check: when x = 1

f(1) = 1 + 19 + 1 +19 = 40

Answer:

3y = -2x + 24

y = -2/3x + 8

Step-by-step explanation:

Answer:

The slope-intercept form is y=mx+b y = m x + b

Step-by-step explanation:

where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by 3 3 and simplify. Divide each term in 3y=24−2x 3 y = 24 - 2 x by 3 3 .
