equation of the line that passes through the point (-8,-1) and is parallel to the line x-4y=4x−4y=4?

Answers

Answer:

Step-by-step explanation:

x - 4y = 4

-4y = -x + 4

y = 1/4x - 1

y + 1 = 1/4(x + 8)

y + 1 = 1/4x + 2

y = 1/4x + 1

Round the decimal to the nearest whole number 5.8??

Answers

Answer:

6

Step-by-step explanation:

Because 5.8 is closer to 6 than it is to 5.

6

If you want to round to the nearest whole number, the answer would be 6. Remember, if the number right after the decimal is higher than 5, you want to round up, if the number is lower that 5, you will want to round down. I hope this helped!! :)

From The Graph Below Determine the total percentage found of each substance expect hydrogen and helium

Answers

Answer:

80%

Step-by-step explanation:

Since we're excluding hydrogen and helium, we are looking for the % of nitrogen and oxygen.

From the graph, we can see that we found 75% oxygen (blue).

We can also see that of nitrogen, green, we found 5%.

We simply need to add these two together.

75% + 5% = 80%

Given the conditional: If the game is field hockey, then the game is a team sport. Find the converse and determine its truth value.

Answers

Answer:

"If the game is a team sport, the game is field hockey"

Truth value → True

Step-by-step explanation:

The conditional statement is,

"If the game is field hockey, then the game is a team sport"

There are two statements,

Statement p → The game is a field hockey.

Statement q → Game is a team sport.

For the converse statement,

If p then q (q → p)

So the converse will be,

"If the game is a team sport, the game is field hockey"

Since, both the statements p and q are TRUE, truth value will be TRUE.

(Converse is false only when q is false and p is true)

Answers

Answer:

y = 2x2

y + 3x = 2x2 – 8

Step-by-step explanation:

The equations that are quadratic in nature are -

y = 2x²2x² - 8 - 3 = 0y = 2x² - 3x - 8

What is a quadratic equation?

A quadratic equation is a equation that is of the form -

y = f{x} = ax² + bx + c.

Given are the set of equations.

A quadratic equation is a equation of degree 2. The equation with degree 2 are -

y = 2x²2x² - 8 - 3 = 0y = 2x² - 3x - 8

Therefore, the equations that are quadratic in nature are -

y = 2x²2x² - 8 - 3 = 0y = 2x² - 3x - 8

Answer:

$1802.47; $1784.47; $1733.20; $2121.83; $2224.59

Step-by-step explanation:

Variable x = answer

Part 1:

1023.49 + 778.98 = x

$1802.47 = x

Part 2:

1023.49 + 778.98 - 18.00 = x

1802.47 - 18.00 = x

$1784.47 = x

Part 3:

1023.49 + 778.98 - 18.00 - 51.27 = x

1802.47 - 18.00 - 51.27 = x

1784.47 - 51.27 = x

$1733.20 = x

Part 4:

1023.49 + 778.98 - 18.00 - 51.27 + 388.63 = x

1802.47 - 18.00 - 51.27 + 388.63 = x

1784.47 - 51.27 + 388.63 = x

1733.20 + 388.63 = x

$2121.83 = x

Part 5:

1023.49 + 777.98 - 18.00 - 51.27 + 388.63 + 102.76 = x

1802.47 - 18.00 - 51.27 + 388.63 + 102.76 = x

1784.47 - 51.27 + 388.63 + 102.76 = x

1733.20 + 388.63 + 102.76 = x

2121.83 + 102.76 = x

$2224.59 = x

A simpler way to do this is by using the last number and adding or subtracting to that. I showed it this way to give you a better understanding.

If t = -3, what is
[tex] \sqrt{6 - 25t} [/tex]

Answers

Answer:

[tex]9[/tex]

Step-by-step explanation:

So we have the expression:

[tex]\sqrt{6-25t}[/tex]

And we want to find the value of the expression when t is -3.

So, substitute -3 for t:

[tex]\sqrt{6-25(-3)}[/tex]

Multiply:

[tex]=\sqrt{6+75}[/tex]

Add:

[tex]=\sqrt{81}[/tex]

Evaluate:

[tex]=9[/tex]

So, our answer is 9.

And we're done!

If t=-3, then the square root would look like this:
6-75 squared. 6-75 is 69. 69 squared is 8.3.

Tony is 1/2 of a mile ahead of Laura on a jogging path. If Tony is running at 5 miles per hour, and Laura is running at 7 miles per hour, how long will it take Laura to catch up with Tony?

Answers

Answer: Another way of looking at this problem, is that Laura will "gain" 2 miles on Tony in 1 hour. Why? She is going 7 miles in 1 hour, while Tony is only going 5. 7-5 = 2.

 

However, Tony is only .5 miles ahead and the question asks how long will it take for her to catch up, not to overtake him or beat him in some race.

 

I would make a simple ratio here. If in 1 hour/she beats him by 2 miles, x hours/she beats him by .5 miles.  

 

Another way to write that is 1/2 = x/.5

 

If you solve the equation, you get (by cross-multiplication) 2x = .5, x = .5/2, x =1/4.

 

Now, we are dealing with hours, so since there are 60 minutes in one hour, multiple the value you obtain for x by 60 minutes (60*1/4) = 15 minutes.  

 

Therefore, it will take Laura 1/4 of an hour, or 15 minutes, in order to catch up with Tony

HELP!!!Find the measures of angles 1, 2, and 3. Show your work. Choose the correct measures of each angle. A. m∠1=77° m∠2=103° m∠3=77° B. m∠1=77° m∠2=103° m∠3=76° C .m∠1=75° m∠2=103° m∠3=75°

Answers

angle 2 = 103° ( vertically opposite angles )

angle 1 = angle 3

103° + 103° + 2 ( angle 1 ) = 360° ( angle 1 = angle 3 )

or, 206° + 2 (angle 1) = 360°

or, 2(angle 1) = 360 - 206

or, 2(angle 1) = 154°

or, angle 1 = 154/2 = 77°

Answer:

angle 2 = 103° (vertically opposite angles)

angle 1 = angle 3 = 77° (vertically opposite angles)

The domain of a quadratic function is all real numbers and the range is y ≤ 2 how many x intercepts does the function have?

Answers

Answer:3

Step-by-step explanation:

Just #9 please I need help (30 points)

Answers

Answer:

Step-by-step explanation:

The graph starts at x = - 3 and ends x = 2. For all x between -3 and 2, there points on the graph. Hence the domain, in interval notation, is written as

[-3 , 2]

We have closed circles at x = - 3 and x = 2 because -3 and 2 are included in the domain which is indicated by the closed brackets at x = - 3 and x = 2.

The range is the set of possible output values, which are shown on the y-axis.

This is why our graph goes from (-3,8) to (2,3)
