Answer:
5/7 and -7/5
Step-by-step explanation:
slope is - 7/5
if line is written as Ax + By + C = 0
the slope is -A/B
if you work that equation you have
By = - Ax - C
y = (-A/B) × x - C/B
and term multiplying the x is the slope in case you had doubts about the - A/B
the multiplication of the slopes of 2 lines that are perpendicular is - 1
x × -7/5 = -1
x = 5/7
the slope of 2 lines that are parallels is the same, so slope = -7/5
You can plug 1350 or less watts without overloading the circuit.
Step-by-step explanation:
Given,
Circuit overloads at = 2400 watts
Electricity consumed by portable heater = 1050 watts
Let,
x be the additional number of watts you can plug in.
Portable heater + additional watts ≤ Overloading limit
1050 + x ≤ 2400
Subtracting 1050 from both sides

You can plug 1350 or less watts without overloading the circuit.

Complementary angles add up to 90 degrees.
The complement angle to 35 is:
90 - 35 = 55 degrees.
The answer is D.
Answer: 20%
Step-by-step explanation:
First you have to take 1008 and subtract 806.4. Once you get that answer you put it into a division problem. So answer over the first number, being 1008. Then multiply that answer by 100. and that is your percentage.
