Answer:
x = -31

Explanation:
To solve for x, you will need to isolate the x on one side of the equation.

This can be done as follows:
5(x-4) + 2 = -173
5x - 20 + 2 = -173
5x - 18 = -173
5x = -173 + 18
5x = -155
5x/5 = -155/5
x = -31

Hope this helps :)

So you’d distribute first, then combine like terms. After you’ve done that you’d do the inverse to isolate x

Need help for this Algebra question plz!
Vikentia [17]

Answer:

2x+5y=-15

ax+bx=c

slope=-a/b so -2/5 matches up with point slope form

then to get y intercept substitite x in point slope for 0 and solve for Y to get -3

then do c/b to get y intercept, so -15/5, which equals -3.

8 + 8r = 3 + 3r can anyone can help me out​
MAVERICK [17]

Answer:r = -1

Step-by-step explanation:

8+8r-(3+3r)=0

We add all the numbers together, and all the variables

8r-(3r+3)+8=0

We get rid of parentheses

8r-3r-3+8=0

We add all the numbers together, and all the variables

5r+5=0

We move all terms containing r to the left, all other terms to the right

5r=-5

r=-5/5

r=-1

Hope this helps

What is the rule for finding the coordinates of an image reflected over the line y=-x
joja [24]
You can find the coordinates of any graph by using a coordinate table, which looks as so in the chart provided below.

What you do is you, put in the letter x and then put what y is equal to in the second box. You plug in any number for x and you solve in order to find the y coordinate. Once you do, for example for plugging in -1 into x you get 1. So your coordinate would be (-1,1).

drug sniffing dogs must be 95% accurate in their responses because their handlers don't want them to miss durgs and also don't w
GenaCL600 [577]

Answer:

95% Confidence interval:  (0.8449,0.9951)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Number of times the dog is right, x = 46

\hat{p} = \dfrac{x}{n} = \dfrac{46}{50} = 0.92

95% Confidence interval:

\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting the values, we get:

0.92 \pm 1.96(\sqrt{\dfrac{0.92(1-0.92)}{50}})\\\\ = 0.92\pm 0.0751\\\\=(0.8449,0.9951)

(0.8449,0.9951) is the required 95% confidence interval for the proportion of times the dog will be correct.

How can I solve this does anyone knows?
Ipatiy [6.2K]
A. C = 17h + 15
b. 83 = 17h + 15 
    -15           - 15  subtract 15 from both sides 
    68 = 17h
    ------------
         17               divide both sides by 17
      4=h  
  They cleaned the house for 4 hours
c. C = 20x
to do this last part, you would put both equations into the calculator under y=, then look at the table to determine when the price is the same. According to the calculator, the price is the same at 5 hours
