Answers

Answer: 37 km

Step-by-step explanation:

Given

The total length of the three roads is 245 km

Suppose the length of PQ is  [tex]x\ km[/tex]

According to question

The Length of PR is  [tex]x+15[/tex]

The length of QR is  [tex]3(x+15)[/tex]

The Sum of PQ, PR, and QR is

[tex]\Rightarrow x+x+15+3(x+15)=245\\\Rightarrow 5x+60=245\\\Rightarrow 5x=185\\\Rightarrow x=37 km[/tex]

length of PQ=37 km

The answer is y=2x+2

Answer:

y = 2x + 2

Step-by-step explanation:

First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.

(0, 2) & (6, 14)

Plug in these values:

(14 - 2) / (6 - 0)

Simplify the parentheses.

= (12) / (6)

Simplify the fraction.

12/6

= 2

This is your slope.

Now plug this into the standard slope-intercept equation: y = mx + b

y = 2x + b

b is the y-intercept, or the value of y when x = 0. If y=we look at the table, we can see that when x = 0, y = 2.

Therefore, our b-value is 2.

Plug this into our equation.

y = 2x + 2

Hope this helps!

C and A are congruent since they are alternate interior angles.
Angles B and A are a linear pair. Linear pairs are supplementary as well. Since we know A is 44, all the have to do is 180-44 . That equals 136.

Answers

Answer:

D. y - 2 = 2(x + 1)

Answers

Answer: the statement “measure of <4 is 105 degrees” is incorrect.

Explanation: This is because since both angles 1 and 3 are vertical, this means they are both 95. This gives us 190 (95x2). Now we subtract this from 360 which gives us 170. Since angles 2 and 4 are vertical, we divide by 2, which gives us 85, not 105.

Three friends were playing a game of marbles. At the end of the game, Marcy had 25% of the marbles, Roger had21of the marbles, and Ann had the rest of the marbles. If there were 100marbles altogether, how many marbles did Ann have at the end of the game​

Answers

Answer:

54

Step-by-step explanation:

total no. of marbles=100

no. of marbles Marcy had

=25% of 100

=25/100×100

=25

no. of marbles Roger had=21

Let the no. of marbles Ann had=x.

So, 25+21+x=100

46+x=100

x=100-46=54

Therefore, Ann had 54 marbles at the end of the game.

Answer:

Look below.

Step-by-step explanation:

K(x)=x^2 isnt graphed but P(x)=x^2+n is. We could use this information to figure out what n is. In a quadratic function we always have the same points unless we are transforming it.

X   Y  

2   4

1    1

0   0

-1    1

-2   4

If we compare what the points were in the parent function to what is shown now we could see that the graph went down 6. From this information we can conclude that n must be -6.
