what will be the new coordinate of vertex b if the triangle is dilated with a center at the origin by a scale factor of 1/3

Answer:

c

Step-by-step explanation:

First, I'll isolate the x in x+4y=5 to match with the other equation.

The new equation would be x= -4y+5

Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.

-1(-12y + 15 = 3x )

3(-4y + 5 = x)

The new equations would be :

12y - 15 = -3x

-12y + 15 = 3x

Add the equations and you get

0 = 0

The equation has an infinite amount of solutions

Step-by-step explanation:

The two given equations have slope -1/2 and 2 and are perpendicular lines.

The lines on the graph are different from the equations at left.

Their slopes are 2 and 1/2. Since they are not opposite reciprocals, they are not perpendicular.

Step-by-step explanation:

1). [tex]\frac{2}{3}n-\frac{3}{4}n+\frac{1}{6}n+2\frac{2}{9}n[/tex]

= [tex]\frac{2}{3}n-\frac{3}{4}n+\frac{1}{6}n+(2+\frac{2}{9})n[/tex]

= [tex](\frac{2}{3}-\frac{3}{4}+\frac{1}{6})n+(2+\frac{2}{9})n[/tex]

= [tex](\frac{8}{12}-\frac{9}{12}+\frac{2}{12})n+(2+\frac{2}{9})n[/tex]

= [tex]\frac{(8-9+2)}{12}n+(2+\frac{2}{9})n[/tex]

= [tex]\frac{1}{12}n+(2+\frac{2}{9})n[/tex]

= [tex](\frac{1}{12}+2+\frac{2}{9})n[/tex]

= [tex](\frac{3}{36}+\frac{72}{36}+\frac{8}{36})n[/tex]

= [tex]\frac{83}{36}n[/tex]

= [tex]2\frac{11}{36}n[/tex]

2). [tex]\frac{2}{5}g-\frac{1}{6}-g+\frac{3}{10}g-\frac{4}{5}[/tex]

= [tex](\frac{2}{5}-1+\frac{3}{10})g-(\frac{1}{6}+\frac{4}{5})[/tex]

= [tex](\frac{4}{10}-\frac{10}{10}+\frac{3}{10})g-(\frac{5}{30}+ \frac{24}{30})[/tex]

= [tex](\frac{4-10+3}{10})g-(\frac{5+24}{30})[/tex]

= [tex]\frac{-3}{10}g-\frac{29}{30}[/tex]

= [tex]-\frac{3}{10}g-\frac{29}{30}[/tex]

3). [tex]i+6i-\frac{3}{7}i+\frac{1}{3}h+\frac{1}{2}i-h+\frac{1}{4}h[/tex]

= [tex]7i-\frac{3}{7}i+\frac{1}{2}i+\frac{1}{3}h-h+\frac{1}{4}h[/tex]

= [tex](7-\frac{3}{7}+\frac{1}{2})i+(\frac{1}{3}-1+\frac{1}{4})h[/tex]

= [tex](\frac{98}{14} -\frac{6}{14}+\frac{7}{14})i+(\frac{4}{12}-\frac{12}{12}+\frac{3}{12})h[/tex]

= [tex](\frac{98-6+7}{14})i+(\frac{4-12+3}{12})h[/tex]

= [tex]\frac{99}{14}i-\frac{5}{12}h[/tex]

-72/-12 equals 6.

Answer:

What is the sum of the measures of the interior anles of a convex 13-gon? There is a formula... the sum of the measures of the interior angles of a convex n-gon is (n-2)180 degrees. For a triangle, n=3, so it's (1)180=180 degrees.

Step-by-step explanation:

180(n-2)

n=number of sides

from question, number of sides=13

substitute 13 into the equation given above

180(13-2)

180(11)

1980 is the answer

Answer:

255.682%

Step-by-step explanation:

From the above question:

The planet mercury makes its circuit around the sun in 88 days.

Venus takes 225 days to complete it's circuit.

Venus's travel time is what percent of Mercury's travel time?

This is calculated as:

(Number of days Mercury take to complete it's circuit/Number of days Venus takes to complete it's circuit) × 100

= 225/88 × 100

= 2.5568181818181817 × 100

= 255.68181818%

Approximately = 255.682%

Venus's travel time is 255.682 percent of Mercury's travel time

Answer:

3 hours and 40 minutes I think

Step-by-step explanation:

Answer:

3 hours and 40 mins

Step-by-step explanation

First, you check 3 hours times 50 miles and 3 hours times 60 miles to get how close they are. 3x50=150, and 3x60=180. 150+180=330. Then you multiply 4/6 or 2/3 by 5 and 6 then add them (because 40 mins is 2/3 of an hour) 50x2/3/2=100/3 and 60x2/3=120/3=40. 40+50/3=73 1/3. 73 1/3+330= 3 hours and 40 mins.

Answer:

Sqaure root of 3 divided by 2

Step-by-step explanation:

The value of function  sin 60° is √3/2.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We need to find the value of sin 60°

Sin 60 degrees is nothing but sin π/3

The sine function we obtain by dividing the opposite side by hypotenuse.

sin theta = Opposite side/ hypotenuse

sin 60=√3/2

The value of sin 60 degrees is square root of three by two.

Hence, the value of function  sin 60° is √3/2.

He scored 22 points.

Step-by-step explanation:

Anthony scored 5 points. Chareles scored 3 times as much and thats 15. minus 4 is 11. 11 times 2 is 22!

THe correct option is the 3rd option

Answer:

x > 1

Step-by-step explanation:

15 - 1 = 14

The inequality is 15 - 1 < 14, but this is incorrect. 14 can not be less than 14. In order for the left side to be less than 14, the x value (currently representing 1) should be larger than what it currently is to make the statement true.

Therefore, x>1

Answer:

12

Step-by-step explanation:

x² - 16x + 60 = -12

→ Add 12 to both sides

x² - 16x + 72 = 0

5 + 4.5 + 2.5 = 12 ÷ 3 = 4

how I know mean is when you add each together then divide it by how many things you added together so we added 3 things together so just divide your answer by 3.

[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ A \ is \ correct . }}}[/tex]

For the number line refer to the attachment :

A linear inequality is given to us . And we need to find the correct number line. So the given linear inequality is :-

[tex]\bf \implies 5x + 3 > 4x + 7 \\\\\bf\implies 5x - 4x > 7 - 3 \\\\\bf\implies \boxed{\red{\bf x > 4 }}[/tex]

This implies that the value of x is Greater than 4 . That is the inequality can have all the values more than 4. So when we see the given number lines we see that the first number line represents all values greater than 4 .

Answer: B is correct
