Answer 1

Answer:

g(u) = -3/2 u + 1/4

Step-by-step explanation:

Solve for v

-12u +3 = 8v +1

Subtract 1 from each side

-12u +3-1 = 8v +1-1

-12u +2 = 8v

Divide each side by 8

-12u/8 +2/8 = 8v/8

-3/2 u + 1/4 = v

v = -3/2 u + 1/4

g(u) = -3/2 u + 1/4

What is the percent of change in the cost of a DVD set that originally sold for$69.99 and is now on sale for $44.99? Round your answer to the nearest whole number.

Answers

Answer: 36%; yes, the % change is equal to the percent discount

Step-by-step explanation:

Initial price = $69.99

Final price = $44.99

change in price = |(final - initial)|

change in price = |(44.99 - 69.99)|

change in price = $25

25/69.99 = x/100

100(25/69.99) = x

100(0.357) = x

35.7% = x

x = 36%

Answers

Answer:

4% account - $1500

4.75% account - $3000

Step-by-step explanation:

x = amount of money in the account that pays 4% interest

y = amount of money in the account that pays 4.75% interest

x + y = 4500

0.04x + 0.0475y = 202.50

4x + 4y = 18000

4x + 4.75y = 20250

  4x + 4y = 18000

- (4x + 4.75y = 20250)

= -0.75y = -2250

y = 3000

x + 3000 = 4500

x = 1500

This is how I do!

Step-by-step explanation:

51-2z-8z=23

We simplify the equation to the form, which is simple to understand  

51-2z-8z=23

We move all terms containing z to the left and all other terms to the right.  

-2z-8z=+23-51

We simplify left and right side of the equation.  

-10z=-28

We divide both sides of the equation by -10 to get z.

2.state the measure of angle 5 and how you know

Thank you!

Answers

Answer:

1. No, Joe is not correct

2. [tex]\angle 5=72^{\circ}[/tex]

Step-by-step explanation:

Given: b and c are parallel lines

To find:

1. whether the given statement is correct or not

2. [tex]\angle 5[/tex]

Solution:

1.

Sum of two angles that form a linear pair is equal to [tex]180^{\circ}[/tex]

[tex]\angle 3+72^{\circ}=180^{\circ}[/tex] (linear pair)

[tex]\angle 3=180^{\circ}-72^{\circ}=108^{\circ}\neq 90^{\circ}[/tex]

So, Joe is not correct

2.

If two lines are parallel then alternate interior angles are equal.

As b and c are parallel lines,

[tex]\angle 5=72^{\circ}[/tex] (alternate interior angles)

Next you can solve it by moving all the unrelated terms to the other side :

[tex] - 2 < x + 3 \\ - 2 - 3 < x + 3 - 3 \\ - 5 < x \\ x > - 5[/tex]

[tex]x + 3 < 5 \\ x + 3 - 3 < 5 - 3 \\ x < 2[/tex]

Answer:

What's the eleventh term of a sequence with an explicit rule of ƒ(n) = 2 + 3(n – 1)?

Question 16 options:


A)


ƒ(11) = –31


B)


ƒ(11) = 32


C)


ƒ(11) = 23


D)


ƒ(11) = –22

Answers

Answer:

B. F(11) = 32

Step-by-step explanation:

From the explicit equation,

F(n) = 2 + 3(n - 1)

F(11) = 2 + 3(11 - 1)

F(11) = 2 + 33 - 3

F(11) = 35 - 3

F(11) = 32

The 11th term of the sequence with an explicit rule is 32
