A linear function has a slope of 2 and passes through the point (0,6). What is the equation of the line?
pychu [463]
A linear function means you’re working with a line. Lines can be stated in slope-intercept form: y=mx+b.

To make it a linear function, you simply replace “y” with “f(x)” notation: f(x) = mx + b

The information you gave told you m=2 and b=6, since (0,b) is the y-intercept.

Putting that all together you have:
f(x) = 2x + 6

Suppose you are interested in how participants behave in different color conditions. You select 30 participants and assign them
ArbitrLikvidat [17]

The answer is the color of the room

Explanation:

In this study, the color of the room is the factor or variable that is modified by the researcher. Also, it is expected the color of the room affects participants' behavior but not the opposite. This shows the color of the room is an independent variable because this factor is not affected by other variables, and it modifies the dependent variable (behavior). Moreover, in studies, the independent variable is always the one that is changed by the researcher.

Helppppppppppppppppp asappppppp
Pani-rosa [81]

Answer:

140

Step-by-step explanation:

<u>As per picture:</u>

∠PTQ  and ∠RTS are vertical angles and they are equal

  • ∠PTQ = (x + 28)°
  • ∠RTS = (2x + 16)°
  • ∠PTQ  = ∠RTS
  • x + 28 = 2x + 16
  • 2x - x = 28 - 16
  • x = 12

∠PTR is supplementary with ∠PTQ  and their sum is 180°

  • ∠PTQ = 12 + 28 = 40°
  • ∠PTR = 180 - 40 = 140°

A candy store charges $12 per pound for truffles and $8 per pound for caramels. How much of each kind of candy should they put i
ira [324]

Answer:

1.25 pounds truffles + 1.75 pounds caramels

Step-by-step explanation:

12x + 8 ( 3-x) = 29  

12x +24 -8x = 29  

4x = 5  

x = 5/4

1.25 X 12 = $15.00  

1.75 X 8 = $ 14.00  

$15.00 + $14.00 = $29.00
