Answer:

x=40/21

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−3x−3(6x−11)=−7

−3x+(−3)(6x)+(−3)(−11)=−7(Distribute)

−3x+−18x+33=−7

(−3x+−18x)+(33)=−7(Combine Like Terms)

−21x+33=−7

−21x+33=−7

Step 2: Subtract 33 from both sides.

−21x+33−33=−7−33

−21x=−40

Step 3: Divide both sides by -21.

Answer:

y = 2/3x +6  for x< -3

y = 2/3x +1     for x> 3

Step-by-step explanation:

The graph is a line for  x < -3

( - 6,2) and ( -3,4)

The slope is m= ( y2-y1)/(x2-x1)

m = ( 4-2)/(-3 - -6) = 2/ ( -3+6) = 2/3

The slope is 2/3

Using point slope form

y-y1 = m(x-x1)  and the point ( -6,2)

y -2 = 2/3(x - -6)

y -2 = 2/3(x +6)

y-2 = 2/3 x +4

y = 2/3x +6 x< -3

The graph is a line for  x > 3

(3,3) and ( 6,5)

The slope is m= ( y2-y1)/(x2-x1)

m = ( 5-3)/(6-3) = 2/ (3) = 2/3

The slope is 2/3

Using point slope form

y-y1 = m(x-x1)  and the point (6,5)

y -5 = 2/3(x - 6)

y-5 = 2/3 x -4

y = 2/3x +1   x> 3

Answer:

C.

Step-by-step explanation:

Answer:

92

Step-by-step explanation:

If the 4 consecutive even integers have a sum of 380, then the average value is 380/4.

380/4 = 95

There must be 2 integers less than 95 and 2 grater than 95.

The 4 integers are: 92, 94, 96, 98

Sum: 92 + 94 + 96 + 98 = 380

Answer: 92

The 4 consecutive even integers are 92,94,96 and 98 whose sum is 380.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The  4 consecutive even integers has a sum of 380.

x+2+x+4+x+6+x+8=380

Add the like terms

4x+20=380

Subtract 20 on both sides

4x=380-20

4x=360

Divide both sides by 4

x=90

So the four consecutive integers are

x+2=90+2=92

x+4=90+4=94

x+6=90+6=96

x+8=90+8=98

Hence, the 4 consecutive even integers are 92,94,96 and 98 whose sum is 380.

Answer:

George's mistake would be:

Instead of 2x + 40, she has made - x + 20.

Step-by-step explanation:

Slope - Intercept Form = y = mx + b

y + 20 = 2(x +20)

y + 20 = 2x + 40

   - 20          - 20

----------------------

y = 2x + 20

(Should have been the answer)

BUT,

George's Solving:

y + 20 = 2(x + 20)

y + 20 = -x + 20

George's Mistake would be her miscalculation during her 2nd step. Where instead of distributing 2 to (x + 20), she has changed it to -x + 20, when in reality, it should have been 2x + 40.

Answer:  see proof below

Step-by-step explanation:

Use the following Half-Angle Identities:

sin² A = (1 - cos 2A)/2

cos² A = (1 + cos 2A)/2

Proof LHS → RHS:

LHS:                          sin⁴ A

[tex]\text{Simplify:}\qquad \qquad \dfrac{\frac{2}{2}[1-2\cos (2A)]+\frac{1+\cos (4A)}{2}}{4}[/tex]

                         [tex]=\dfrac{2-4\cos (2A) + 1 + \cos (4A)}{8}[/tex]

                         [tex]=\dfrac{1}{8}\bigg(3-4\cos (2A)+\cos (4A)\bigg)[/tex]

LHS = RHS  [tex]\checkmark[/tex]

Let's start from LHS...

LHS = sin^4A = sin^2A * sin^2A

We can apply a few formulas here;

cos 2A = 1 - 2sin^2A

sin^2A = (1 - cos2A) / 2

cos2A = 2cos^2A - 1

cos^2A = (1 + cos2A) / 2

According to the second formula, sin^2A * sin^2A = (1 - cos2A) / 2 * (1 - cos2A) / 2.

(1 - cos2A) / 2 * (1 - cos2A) / 2 = 1/4(1 - cos2A)^2

We can simplify "(1 - cos2A)^2." Remember that (a - b)^2 = a^2 - 2ab + b^2. Similarly (1 - cos2A)^2 = (1 - 2cos 2A + cos^2 2A);

1/4(1 - cos2A)^2 = 1/4(1 - 2cos 2A + cos^2 2A)

According to the fourth formula, cos^2 2A = (1 + cos4A) / 2;

1/4(1 - 2cos 2A + cos^2 2A) = 1/4(1 - 2cos 2A + (1 + cos4A) / 2)

= (taking LCM) 1/4( (2 - 4cos 2A + 1 + cos4A)/2 )

= (simplified) 1/8(3 - 4cos 2A + cos 4A)

Step-by-step explanation:

Answer: K= 12

A=10

P= 6

B=pi/3

Equation: y=10sin(pi/3(x))+12

Step-by-step explanation: You can find k by finding the midline, or adding the minimum and maximum y values together and then dividing by 2.

You find a by using the midline value (12) and subtracting it from the maximum y value to get the amplitude.

To find the period, find the difference between the min and max x values, which is 3, then double it to get the full period.

To find the b value, plug it into the 2pi/b=p equation, using the period value you found before you should get pi/3.

When assembling the equation use this format: y=asin[b(x-h)]+k.

You can also graph it with a graphing calculator to check to be sure the max and min points line up.

A sine function is represented as: [tex]\mathbf{y = A\sin(Bx) + k}[/tex]

The given parameters are:

[tex]\mathbf{(x_1,y_1) = (4.5,2)}[/tex]

[tex]\mathbf{(x_2,y_2) = (1.5,22)}[/tex]

(a) The vertical shift (k)

The vertical shift is calculated using:

[tex]\mathbf{k = \frac{y_1 + y_2}{2}}[/tex]

So, we have:

[tex]\mathbf{k = \frac{2 + 22}{2}}[/tex]

[tex]\mathbf{k = \frac{24}{2}}[/tex]

[tex]\mathbf{k = 12}[/tex]

(b) The amplitude (A)

The amplitude is calculated using:

[tex]\mathbf{A = \frac{y_2 - y_1}{2}}[/tex]

So, we have:

[tex]\mathbf{A = \frac{22 - 2}{2}}[/tex]

[tex]\mathbf{A = \frac{20}{2}}[/tex]

[tex]\mathbf{A = 10}[/tex]

(c) The period (p) and the frequency factor (b)

The period is calculated using:

[tex]\mathbf{p = x_1 + x_2}[/tex]

So, we have:

[tex]\mathbf{p = 4.5 + 1.5}[/tex]

[tex]\mathbf{p = 6}[/tex]

The frequency factor (b) is calculated using:

[tex]\mathbf{b = \frac{2\pi}{p}}[/tex]

So, we have:

[tex]\mathbf{b = \frac{2\pi}{6}}[/tex]

[tex]\mathbf{b = \frac{\pi}{3}}[/tex]

(d) The equation of the sine function

A sine function is represented as:

[tex]\mathbf{y = A\sin(Bx) + k}[/tex]

So, we have:

[tex]\mathbf{y = 10\sin(\frac{\pi}{3}x) + 12}[/tex]

Answer:

(-162)/7 or -23 1/7 as mixed fraction

Step-by-step explanation:

Simplify the following:

(-36)/14 (-18) (-3)/6

Hint: | Express (-36)/14 (-18) (-3)/6 as a single fraction.

(-36)/14 (-18) (-3)/6 = (-36 (-18) (-3))/(14×6):

(-36 (-18) (-3))/(14×6)

Hint: | In (-36 (-18) (-3))/(14×6), divide -18 in the numerator by 6 in the denominator.

(-18)/6 = (6 (-3))/6 = -3:

(-36-3 (-3))/14

Hint: | In (-36 (-3) (-3))/14, the numbers -36 in the numerator and 14 in the denominator have gcd greater than one.

The gcd of -36 and 14 is 2, so (-36 (-3) (-3))/14 = ((2 (-18)) (-3) (-3))/(2×7) = 2/2×(-18 (-3) (-3))/7 = (-18 (-3) (-3))/7:

(-18 (-3) (-3))/7

Hint: | Multiply -18 and -3 together.

-18 (-3) = 54:
