If there is supposed to be a “y” after 6 the answer would be y=6 but if it isnt the answer is y= - 26
Answer:
or ![y=-0.625x+7.5](https://tex.z-dn.net/?f=y%3D-0.625x%2B7.5)
Step-by-step explanation:
The question is
Find the slope intercept form of the line parallel to the line 5x+8y=120 passing through (4,5)
step 1
Find the slope of the given line
we have
![5x+8y=120](https://tex.z-dn.net/?f=5x%2B8y%3D120)
isolate the variable y
![8y=-5x+120](https://tex.z-dn.net/?f=8y%3D-5x%2B120)
![y=-(5/8)x+15](https://tex.z-dn.net/?f=y%3D-%285%2F8%29x%2B15)
The slope of the given line is m=-5/8
step 2
Find the slope of the line parallel to the given line
we know that
If two lines are parallel, then their slopes are the same
so
The slope of the parallel line to given line is m=-5/8
step 3
Find the equation of the line into slope intercept form
The equation of the line into slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
we have
m=-5/8 and point (4,5)
substitute and solve for b
![5=-(5/8)(4)+b](https://tex.z-dn.net/?f=5%3D-%285%2F8%29%284%29%2Bb)
![b=5+(20/8)](https://tex.z-dn.net/?f=b%3D5%2B%2820%2F8%29)
![b=60/8=15/2=7.5](https://tex.z-dn.net/?f=b%3D60%2F8%3D15%2F2%3D7.5)
substitute
![y=-(5/8)x+(15/2)](https://tex.z-dn.net/?f=y%3D-%285%2F8%29x%2B%2815%2F2%29)
or
![y=-0.625x+7.5](https://tex.z-dn.net/?f=y%3D-0.625x%2B7.5)
Answer:
i think its B
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
You are trying to find which t value gives you the answer of 13. Set the equation equal to 13 and solve for t.
-2t + 5 = 13
-2t + 5 - 5 = 13 - 5
-2t = 8
-2t/-2 = 8/-2
t = -4
