Answer:

y = -7/5x - 6.7

Step-by-step

y = -7/5x + 6. A Line that is parallel will always have the same slope. The slope is m. m in this situation = -7/5x. A lines equation is y = mx + b. m = -7/5. y = -7/5x + b. Now to find b we can substitute the given point which goes through the new line, (2, -6). In this point x =2 and y = -6. Now substitute the x and y values into our equation. y = -7/5x + b is now -6 = -7/5(2) + b. -7/5(2) = -7/10. -6 = 7/10 + b. Subtract 7/10 from -6. Its -6 and 7/10 or -6.7 . -6.7 = b. b = -6.7. Now substitute the b value into the equation. y = -7/5x -6.7.

An amusement park sold 27 child tickets. The other 23 tickets it sold were adult tickets. What is the ratio of the number of adu

amm1812

Answer:

23/50

Step-by-step explanation:

27 + 23 = 50 (Implying that 50 is the total amount of tickets).

23 of them were sold to adults, so basically 23/50.

Remember a ratio can be written in 3 forms, so it can be either of these:

23:50

23/50

23 to 50

Given line LM and point R that lies on line LM, identify the following ratios given that point R lies a/b of the way along line

gavmur [86]

Answer:

See explanation

Step-by-step explanation:

If point R lies $\frac{a}{b}$ of the way along line LM, closer to L than M, then

$LR=ax\\ \\LM=bx$

Find all needed ratios:

1. $\dfrac{LR}{LM}=\dfrac{ax}{bx}=\dfrac{a}{b}$

2. By segment addition postulate,

$LR+RM=LM\\ \\RM=bx-ax=(b-a)x,$

$\dfrac{RM}{LM}=\dfrac{(b-a)x}{ax}=\dfrac{b-a}{a}$

3. $RL=LR=ax\\ \\RM=(b-a)x,$

then

$\dfrac{RL}{RM}=\dfrac{ax}{(b-a)x}=\dfrac{a}{b-a}$

calculation with distribuation would be multipling each fraction by 6 first then add them together

1/2 becomes 3 2/3 becomes 4 3/4 becomes 9/2 now add them together 23/2 or 11 1/2 Now without distribuation you woud add everything togther then mutiply by 6 adding together would give you 23/12 then multiplying by 6 gives you 23/2
