Sub j(x)=-5 into the first eq.
-5=(4/5x)+7
Add 7 to both sides
2=4/5x
Muliply both sides times 5x
10x=4
Divide both sides by 10
X=4/10
Simplify
X=2/5
Answer:
x=3.6
Step-by-step explanation:
You subtract 0.68 from 5 and you get 1.2=4.32
Then you put 1.2 under 1.2 and 4.32 to get x on its own on that side you equation now looks like this x=3.6 So that is your answer
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of a line given two points first find the slope of the line and use the formula
y - y1 = m( x - x1) to find the Equation of the line using any of the points given
Slope of the line using points
(3,2) and (4,6) is
So the equation of the line using point
( 3 , 2 ) and slope 4 is
<h3>y - 2 = 4( x - 3)</h3>
Hope this helps you
Domain 0≤x≤12 this means the domain (x values) are between x=0 and x=12 and you started measuring the degree of temperature starting at a time of 0 and stopped measuring the temperature at a time of 12 hours
Range -4≤y≤4 this means the range (y values) are between y=-4 and y=4. The range is referring to the degree in celcius based on what time you measured it
Hope this helps!
