The factor that changes when the manipulated, or independent, variable is changed is known as the dependent variable. This variable is one of the two variables that are being investigated. When graphing the results of an experiment, the independent variable's values are placed on the x-axis of the graph and the values of the dependent variable are placed on the y-axis. An example of a manipulated variable and dependent variable relationship is seen in an investigation where the effect of temperature (manipulated) is seen on the amount of sugar that can be dissolved in water (dependent).
Answer:
x=9 and angle B = 40°.
Step-by-step explanation:
Since angles A and B are corresponding angles, they both equal one another. Your equation should be set up like this:
5x-5° = 3x+13°
Once you solve for x, you'll get 9.
To solve for angle B, plug the value of x in the equation:
3(9)+13°
27+13°
Angle B = 40°.

Distance formula is:
Sqrt of (x-x1)^2+(y-y1)^2
So define which coordinate is (x,y) and what (x1,y1)
I’m going to define (-10,-7) as (x,y) and (2,9) as (x1,y1)
So plug in your variables!
Sqrt(-10-2)^2+(-7-9)^2
Sqrt-12^2+-16^2
Sqrt144+256
Sqrt400
So sqrt of 400 is 20! :))
Answer: 5
Step-by-step explanation:
f(x)=3-x
f(-2)=3-(-2)
f(-2)=3+2
f(-2)=5
Hope this helps!! :)
Please let me know if you have any question
75/4=25 pages per hour, so, now we have to divide 250 by 25.
250/25=10
So, it would take Joan 10 hours to read 250 pages. :)
