(8.59 × 104) – (3.2 × 103)

Answer:

x=18

Step-by-step explanation:

XZ/RT=XY/RS

60/40=(5x-3)/(3x+2)

1.5=(5x-3)/(3x+2)

1.5(3x+2)=5x-3

4.5x+3=5x-3

9=0.5x

18=x

Answer:

5. yes

6. yes

7. no

8. no

Step-by-step explanation:

5. Divide 20 and 10 by 10, and you'll get 2:1

6. Divide 20 and 15 by 5, and you'll get 4:3

7. If you divide 20 and 10, you'll get 2:1 not 1:2

8. 14 is not a multiple of 3

87/14 or 6 3/4. That's an improper fraction and then a mixed fraction. Same answer though

Answer:

The answer is

D. V= 19200- 12t

Step-by-step explanation:

in this problem, we already know that the pool contains 19200 gallons of water

and the pool is draining at 12 gallons per minutes, hence the volume is decreasing at that rate

Therefore for t minutes it will decrease by 12t

hence the volume after t minutes will be

V= 19200-12t

Answer:

{9,19,39,79}

Step-by-step explanation:

Recursive Sequences

The recursive sequence can be identified because each term is given as a function of one or more of the previous terms. Being n an integer greater than 1, then:

f(n) = 2f(n-1)+1

f(1) = 4

To find the first four terms of the sequence, we set n to the values {2,3,4,5}

f(2) = 2f(1)+1

Since f(1)=4:

f(2) = 2*4+1

f(2) = 9

f(3) = 2f(2)+1

Since f(2)=9:

f(3) = 2*9+1

f(3) = 19

f(4) = 2f(3)+1

Since f(3)=19:

f(4) = 2*19+1

f(4) = 39

f(5) = 2f(4)+1

Since f(4)=39:

f(5) = 2*39+1

f(5) = 79

A.

Divide the numbers

1 + 4x 2/2 • x =5x

1 + 4x + 1x =5x

Multiply by 1

1 + 4x + 1x=5x

Combine like terms

1 + 4x + x =5x

1 + 5x =5x

Subtract 1 from both sides of the equation

5x + 1 = 5x

5x + 1 - 1 =5x -1

Simplify

Subtract the numbers

5x = 5x -1

Subtract 5x from both sides of the equation

5x = 5x -1

5x - 5x = 5x -1 -5x

Simplify

0= -1

Result

0= -1

idk the ans in letter B

Finding slope:

Take two pairs of cordinate points from the table and use the formula y2-y1 divided by x2-x1

I choose (4,3) and (2,2)

2-3 divided by 2-4

= -1/2

Then to get the y intercept you use the formula: y=mx+b

For the x and y pick a cordinate to plug in. For m plug in your slope.

I pick (6,4)

4=-1/2×6+b

Multiply -1/2 and 6 to get -3 and plug that in

4=-3+b

Now add 3 to the -3 canceling that out to 0 and add three to the 4 making that 7

7=b

Y-intercept =7

Now plug in the slope and y-intercept into the slope intercept format and get:

Y=-1/2x+7

Answer:

-0.6

Step-by-step explanation:

The answer is negative because -45 was a negative number.

Answer:

Step-by-step explanation:

1) h(t) = 5t + 10

2) plugging in t as 12 to our function, h(12) = 5 * 12 + 10 = 70

3) h(5) = 35 is the function representing the height, 35 feet, travelled in a period of time, 5 seconds.

Answer:

[tex]m=-54[/tex]

Step-by-step explanation:

We have the equation [tex]3-\frac{m}{6}=12[/tex] and we want to solve for m using the Properties of Equality.

Steps:

1) Subtraction Property of Equality (subtract 3 from both sides):

[tex](3-\frac{m}{6})-3=(12)-3[/tex]

[tex]-\frac{m}{6}=9[/tex]

2) Multiplication Property of Equality (multiply both sides by -6):

[tex]-6(\frac{m}{-6})=-6(9)[/tex]

[tex]m=-54[/tex]

Therefore, our final answer is [tex]m=-54[/tex]

Question:

Which description could be written as a linear function?

Answer:

Option a)

Explanation:

Let 2 numbers be x1 and x2.

For the first option:

Eight more than twice a number.

The graph would be y = 8 + 2x1 which is a linear function.

For the second option:

Three more than the product of two numbers.

The graph would be y = 3 + x1x2 which is a graph function.

For the third option:

Ten more than the square of a number.

The graph would be y = 9 + (x1)² which is a graph function.

For the fourth option:

Nine more than one divided by a number.

The graph would be y = 9 + 1/x1 which is a double-parabole function.

Hopefully this answer will help you.
