A) -4
d) -3.1
for these questions you have to subtract the two numbers since they have different signs and the biggest sign is the ending sign
Answer:

Step-by-step explanation:
Hello!
Use the distributive property and multiply like terms.
<h3>Simplify</h3>
The simplified form is
.
Answer: (A) H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Step-by-step explanation:
Usually null hypothesis represents the claim that the values associated to the groups being tested have no statistical difference but alternative hypothesis supports the claim that there is statistical difference.
Let
be the population mean .
We are given that the mean potassium content of a popular sports drink is listed as 140 mg in a 32-oz bottle.
i.e. Null hypothesis :
Alternative hypothesis for two tail hypothesis has sign (≠).
i.e. Alternative hypothesis : 
∴ The hypotheses for a two-tailed test of the claimed potassium content:
H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Answer:
12
Step-by-step explanation:
3x+2y=12
2y=-3x+12
y=-3/2+12
Honestly you dont have to do any of this work but i did it anyways, The y coordinate is always at the end of the point intercept form (y=mx+b form)
Answer:find the slope
Step-by-step explanation:
I don't know if you know how to find the slope if not reply back. But that's what the equation wants you to do.
