Answer:
A)
6x - y = 8
3x + 2y = 9
(Graph is attached for you⤴⤴⤴)
Step-by-step explanation:
Line m ordered pairs = (-4,-32), (2,4),
(5, 22)
Line n ordered pairs = (-5,12), (1,3), (5,-3)
Use this formula⤵⤵⤵
[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]
For line m, we'll use (2,4) and (5,22):
22 - 4 = 18
5 - 2 = 3
18 ÷ 3 = 6
Slope of line m = 6
For line n, we'll use (1,3) and (5,-3):
-3 - 3 = -6
5 - 1 = 4
Slope of line n = -6/4 or -3/2
We'll turn all the options to slope-intercept form, so we can tell which has the slopes we need.
A) - Subtract 6x on both sides to get
-y = -6x + 8, then flip all the signs to get y = 6x - 8.
- Subtract 3x on both sides to get 2y = -3x + 9, then divide 2 on both sides to get y = -3/2 x + 9/2.
B)
- Subtract 6x on both sides to get
y = -6x - 8.
- Subtract 3x on both sides to get
-2y = -3x + 9, then divide -2 on both sides to get y = -3/2 x - 9/2.
C)
- Add 6x on both sides to get -y = 6x - 8, then flip all signs to get y = -6x + 8.
- Add 3x on both sides to get 2y = 3x + 9, then divide 2 on both sides to get
y = 3/2 x + 9/2.
D)
- Subtract 6x on both sides to get
-y = -6x - 8, then flip all signs to get
y = 6x + 8.
- Add 3x on both sides to get -2y = 3x + 9, then divide -2 on both sides to get
y = -3/2 x - 9/2.
Hope this helps :)

Consider a sample of 52 football games where 32 of them were won by the home team use a 0.01 significance level to test the claim that the probability that the home team wins is greater than one half
Answers
According to the information given, it is found that:
The hypothesis tested are:C. [tex]H_0: p = 0.5[/tex], [tex]H_1: p > 0.5[/tex]
The test statistic is z = 1.66.The p-value of the test is of 0.0485.The conclusion is:Fail to reject [tex]H_0[/tex], as there is not sufficient evidence to conclude that the probability that the home team wins is greater than one half.
At the null hypothesis, it is tested if home teams win half their games, that is, if the proportion is of 0.5, hence:
[tex]H_0: p = 0.5[/tex]
At the alternative hypothesis, it is tested if home teams win more than half their games, that is, if the proportion is of more than 0.5, hence:
[tex]H_1: p > 0.5[/tex]
The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.For this problem, the parameters are:
[tex]p = 0.5, n = 52, \overline{p} = \frac{32}{52} = 0.6154[/tex]
Hence, the value of the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.6154 - 0.5}{\sqrt{\frac{0.5(0.5)}{52}}}[/tex]
[tex]z = 1.66[/tex]
The test statistic is z = 1.66.
The p-value is the probability of finding a sample proportion above 0.6154, which is 1 subtracted by the p-value of z = 1.66.
Looking at the z-table, z = 1.66 has a p-value of 0.9515.1 - 0.9515 = 0.0485.
The p-value of the test is of 0.0485.
Since the p-value is greater than 0.01, the conclusion is:
Fail to reject [tex]H_0[/tex], as there is not sufficient evidence to conclude that the probability that the home team wins is greater than one half.

Hong's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Hong $5.80 per pound, and type B coffee costs $4.20 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $700.60 . How many pounds of type A coffee were used?
Answers
Answer:
31 Pounds
Step-by-step explanation:
Let x = the number of lbs of Type A coffee.
We know that this month's blend used 4 times as many pounds of type B coffee as type A coffee.
Total lbs of coffee = x + 4x
The total cost then is:
($ cost for Type A)(x) + ($ cost for Type B)(3x) = $700.60
$5.80x + $4.20(4x) = $700.60
$5.80x + $16.8x = $700.60
$22.6x = $700.60
x = 31 lbs
Therefore they where 31 pounds of type A coffee used.
jamie baked 48 cookies, which is 8 less than twice the number of cookies gina baked what is the equation
Answers
So we know that the number x is multiplied by 2 and subtracted by 8 to get the total number of cookies that Gina baked. Lets set up this equation.
48 = 2x - 8
The 2x is our x multiplied by 2 and the - 8 is the 8 less.
Lets solve:
48 = 2x - 8
Add 8 to both sides to isolate the x variable:
48 + 8 = 2x - 8 + 8
56 = 2x
Now we divide the 2 from the 2x in order to fully isolate the variable:
56 = 2x
28 = x
Lets plug 28 in to double check the answer:
48 = 2(28) - 8
48 = 56 - 8
48 = 48
Yes!
I hope this helps! :)
