Because y is 8 and x is 3 you just have to add it in the equation which means to times it,(8)2-3(3)
8x2=16
3x3=9
16-9=7

(-4,1) and (-8,7) <br><br> write an equation in slope-intercept form
Alchen [17]

Answer:

y = -2x - 9

Step-by-step explanation:

so we have our two points, (-4,-1) and (-8,7) What we need to do to find our slope is y2 - y1 over x2 - x1. Once plugging in the numbers and subtracting it should give you 8/-4. 8 divided by -4 is -2. m = -2. Now to find our "b" we plug in our slope, and plug in one of the two points into the format of y = mx + b.

-1 = -2(-4) + b

multiply -2 and -4

-1 = 8 + b

we subtract 8 from itself and -1

-9 = b

Our equation is y = -2x - 9

SHOW THE SOLVING FOR <br> 4v+18&gt;_ 6v+10
SOVA2 [1]
Remember you can do anything to an equaiton as long asyou do it to both sides

4v+18≥6v+10
minus 4v both sides
4v-4v+18≥6v-4v+10
0+18≥2v+10
18≥2v+10
minus 10 both sides
18-10≥2v+10-10
8≥2v+0
8≥2v
divide both sides by 2
8/2=(2v)/2
4≥(2/2)v
4≥1v
4≥v
v≤4

Two owners of a cattle ranch, Jo and Val, want to find the average weight for the ranch's 200 cows. Instead of weighing all of t
Zolol [24]

Answer:

The  value  is E =19.6

Step-by-step explanation:

From the question we are told that

  The mean of Jo  cows is  \= x_1 = 1350

  The standard deviation of Jo cow is  s_1 =  50

  The mean of Val  cows is \= x_2  = 1420

   The standard deviation of Val  cows  is  s_2 =  50

    The sample size for both Val  and  Jo  is  n = 25

Let assume that the level of significance is  \alpha = 0.05

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.96

Generally the margin of error is mathematically represented as  

      E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }

Hence margin of error for Jo is  

=>   E = 1.96 *  \frac{50}{\sqrt{25} }

=>   E =19.6
