Indicate the equation of the given line in standard form. The line through point (-3, 4) and perpendicular to a line that has sl
statuscvo [17]
To be perpendicular the product of the two slopes must equal -1.

2m/5=-1

2m=-5

m=-2.5

since y=mx+b we have so far

y=-2.5x+b, using point (-3,4) we can solve for b

4=-2.5(-3)+b

4=7.5+b

b=-3.5 so

y=-2.5x-3.5  We can multiply the whole equation by two so that the coefficients are integers...

2y=-5x-7  add 5x to both sides

5x-2y=-7

Ice cream is best stores at 4 degree F with an allowance of 3 degree F. What is the best range to store ice cream?
zhuklara [117]

Answer:

1°F to 7°F  is the best range to store ice cream.

Step-by-step explanation:

The ideal storage temperature of ice cream = 4°F

The allowance in the temperature is 3°F

So, the range of the store = 4°F ±  3°F

Now, 4°F + 3°F  =  7°F

and    4°F -  3°F  =  1°F

Hence, 1°F to 7°F  is the best range to store ice cream.
