Answer:

There are 5 steps. The solution is (5/4,5)

Step-by-step explanation:

1. In the y+5x=x+10 equation, subtract 5x from both sides to get y=-4x+10.

2. Set y=-4x+10 and y=4x equal to each other to get -4x+10=4x

3. Add 4x to both sides, which leaves you with 10=8x

4.Divide both sides by 8 to get x=10/8 or 5/4 when you simplify

5. Plug 5/4 into the y=4x equation and multiply 5/4 by 4/1, which leaves you with 20/4, or 5.

So the solution to this problem is (5/4,5). If you graph these two equations, you will get the same solution.

Search results for There were 35 bunches of roses and tulips. Each brunch at 12 of the same flowers. There were seven more bunch

KIM [24]

If it is supposed to say <span>seven more bunches of tulips than roses, that would mean, if there are 35 bunches in all, and if each bunch had 12 of the same flowers.... that must mean each bunch had 12 flowers so, 12*1/2/35. 35/1/2 would be 35/0.5 that would equal... 17.5. so, 12*17.5= 210. if there was seven more added, than, 7/2= 3.5 and 12*3.5= 42. 210+42=252.

That means there are 252 tulips, i might be wrong (i probably am), i am just going by logic, lol

Find the slope of a line that passes through points (-1,-5) and (6,9).

Nana76 [90]

Answer:

${ \rm{slope = \frac{y _{2} - y _{1} }{x _{2} - x _{1} } }} \\ \\ { \rm{slope = \frac{9 - ( - 5)}{6 - ( - 1)} }} \\ \\ { \rm{slope = \frac{14}{7} }} \\ \\ { \boxed{ \rm{ \: \: slope = 2 \: \: }}}$

I need help I don’t understand

lara [203]

you'll first need to understand the symbols, I've attched a cheat sheet :)

you'll need to see if AB is linked to CD reversed.

If not then it's not A

For B you'll have to see if the angles are parralel to each other.

and for C you'll have to see if the angles are the same.

and D is the same as C

so the answer is ab=cd

<h2>now you understand :)</h2>

You will need the same dataset used for problem 3 in homework 1 (the dataset obtained from the yahoo website with the company yo

stepladder [879]

Answer:

a) The probability of sampling at random a fish that is smaller in size than the value you would obtain by subtracting half the standard deviation from the average is 0.3085.

b) The probability of sampling at random a fish that is greater in size than the value you would obtain by adding half the standard deviation from the average is 0.3085.

c) The probability of sampling at random a fish that has a size between the two values is 0.383.

d) The 25th and 75 percentiles of fish size for the population using the normal distribution table is 5.69 and 5.87 respectively.

e) The probability that the average calculated will be less than the value is 0.3707.

Step-by-step explanation:

For the given data set mean $(\mu) = 5.75913$
