What is the equation of this line?
у=2x

y= -2x

y= -1/2x

y= 1/2x


What Is The Equation Of This Line?=2xy= -2xy= -1/2xy= 1/2x

Answers

Answer 1

Answer:

y = -2x

Step-by-step explanation:

since the y-int starts at 0, you would go down 2 (negative) and to the right by 1, 2/1=2

use the equation y=mx+b to find the equation of a graph

m is the slope and b is the y-int

you can also use the method rise/run, where in this case, the rise (down when it’s a negative) is -2 and the run (across) is 1

2 represents the change in y and 1 represents the change in x

when finding the equation of a graph, always check the y-axis for the point then start there. that represents your y-int. then you look for a solid point and see how much units away across and up or down it is from the y-int.

in this case, i went to the point (1, -2).

hope this helps !!

Answers

Answer:

4 and 8

Step-by-step explanation:

4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.

4 and 3 are supplementary angles (they both add up to 180°).

4 and 1 are vertically opposite angles and are equal to each other.

From the above explanations, only 4 and 8 are corresponding angles.

Laura collects nickels and dimes she has a total of 47 nickels and dimes she calculated the value of the coins and found out she has $4.05 how many nickels and dimes does laura

Answers

Answer:

Number of dimes = 34

Number of nickels = 13

Step-by-step explanation:

Total number of coins = 47

Coins are in the form of nickels and dimes.

Value of a nickel = 5 cents

Value of a dime = 10 cents

Total value of coins = $4.05 or 405 cents

To find:

Number of nickels and dimes?

Solution:

Let number of nickels = [tex]x[/tex]

Money value of nickels = 5[tex]x[/tex]

Let number of dimes = [tex]y[/tex]

Money value of dimes = 10[tex]y[/tex]

Total value of coins = [tex]5x+10y[/tex]

This value is given as equal as 405.

As per question statement, the equations can be written as:

[tex]5x+10y = 405 ..... (1)\\x+ y = 47 ...... (2)[/tex]

Multiplying equation (2) with 5 and subtracting from equation (1):

[tex]10y - 5y = 405 - 235 \\\Rightarrow 5y = 170\\\Rightarrow y = 34[/tex]

Number of dimes = 34

Number of nickels  = 47 - 34 = 13

Answers

Answer:

a. is congruent by SSS

b. is congruent by AAS

c. is congruent by ASA

d. is congruent by SAS

Step-by-step explanation:

a. is SSS because all sides are marked

b. is AAS because the point where the two triangles meet are vertical angles and the one side of the triangle is marked congruent making AAS

c. is ASA because the angles are on segment FG and segment BC and there is a congruent line in between the two angles making ASA

d. is SAS because the triangles share the segment QS and when two triangles share a segment, that segment is congruent. the outside segment is congruent and then there is an angle and then the inside segment is congruent

B. The school prom committee sold presale tickets for
$18 each. Couples that showed up on the day of the
dance has to pay $24 each. There were 334 tickets
that were sold and the committee made $7320. How
many students purchased tickets at the dance?

Answers

Answer:

218 students purchased tickets at the dance.

Step-by-step explanation:

Let,

x be the number of presale tickets

y be the number of tickets sold at the dance

According to given statement;

x+y=334      Eqn 1

18x+24y=7320    Eqn 2

Multiplying Eqn 1 by 18

18(x+y=334)

18x+18y=6012      Eqn 3

Subtracting Eqn 3 from Eqn 2

(18x+24y)-(18x+18y)=7320-6012

18x+24y-18x-18y=1308

6y=1308

[tex]\frac{6y}{6}=\frac{1308}{6}\\y=218[/tex]

Therefore,

218 students purchased tickets at the dance.

Twice a number increased by seven is equal to five. Which of the following represents the equation and solution for this statement?

2 n + 7 = 5; n = -4.5
2 n = 7 + 5; n = 6
2 n + 7 = 5; n = -1
2( n + 7) = 5; n = -4.5

Answers

Hey there!

The answer to your question is the third option: 2n + 7 = 5; n = -1

"twice a number increased by 7" would represent 2n + 7, and if it's equal to 5, it would be 2n + 7 = 5. That rules out the last option, and the second option. Now, we have to solve for "n":

2n + 7 = 5         Step 1: Write the equation.

     2n = -2        Step 2: Subtract 7 from both sides.

       n = -1         Step 3: Divide both sides by 2.

Therefore, "n" is equal to -1, and the third option would be correct.

Hope it helps! Have a great day, and good luck on your assignment!

Answers

Answer:

m=-2 b=0

Step-by-step explanation:

first, in order to understand anything, you gotta know what y=mx+b means :)

first, m is just there so you can substitute it for a number. x represents the slope, and b represents the y-intercept, which you also substitute for a number.

so in y= -2x, there's no y intercept, because there is no number that represents the y intercept.

so if we use y=mx+b, we can just substitute the numbers.

which would be, y= -2.

Answer: 3/4= 15/20, 4/5= 16/20

Answer:

15/20    16/20    <

First, make a common denominator for both, which is 20. So, 3/4 = 15/20. Then 4/5= 16/20. 15/20 < 16/20, so 3/4 < 4/5.
