y = - 
x - 1
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange - 7x + 5y = 12 into this form
add 7x to both sides
5y = 7x + 12 ( divide all terms by 5 )
y = 
x + 
← in slope- intercept form
with slope m =
given a line with slope m then the slope of a line perpendicular to it is
perpendicular slope = - 
= -
The partial equation of the perpendicular line is
y = - x + c
to find c substitute (- 7, 4 ) into the partial equation
4 = 5 + c ⇒ c = 4 - 5 = - 1
y = - x - 1 ← in slope- intercept form
Step-by-step explanation:
Rate of drop of temperature = Change in temperature/Rate
=> (165 - 135)/15
=> 30/15
=> 2 ⁰F/min
Now, The time at which the temperature of will be 70⁰F = 70/Rate
=> 70/2
=> 35 min
Time for 110⁰ F
=> 110/2
=> 55 min
The answer is 9.2
If you want simplest form as a fraction it would be 9 1/5
Answer:
c) x^2 / y^4 is da answer
Answer:
0.85 kilograms
Step-by-step explanation:
The nearest hundredth can be defined as a place value used when rounding up numbers after the decimal.
The nearest hundredth can also mean rounding up to 2 decimal places.
We are asked to round up 0.845 to the nearest hundredth
The nearest hundredth is the second number after the decimal = 4
The third number after the decimal = 5, hence we add 1 to 4 , making it 5.
Hence:
0.845 kilograms to the nearest hundredth = 0.85 kilograms
