For the equation to be equal it should have a slope of -3
a is part of the equation of the second line.b. <span>is</span> not part because x-3y=-3 -3y=-x-3 y= 1/3x+1 so it is not part of <span>the</span> equation of the second line<span>c</span> is part because y= -3x-6
d. <span>is</span> part because 6x+2y=2 2y=-6x+2 y= (-6x+2<span>)</span>/2 y=-3x+1
So <span>yor</span> answer is B.
Answer:
-20, -18, -16
Step-by-step explanation:
For consecutive integer problems, it often works well to let a variable represent the middle one (or their average value).
__
Here, we can let x represent the second integer. Then the first is (x-2), and the third is (x+2). The given relation can be written as ...
(5 +x)(-7) = 11 +5(-(x+2))
-35 -7x = 11 -5x -10 . . . . . . eliminate parentheses
-36 = 2x . . . . . . . . . add 7x -1
-18 = x . . . . . . . . divide by 2
The three integers are -20, -18, -16.
Answer:
12 miles = 72 minutes
1/6 miles = 1 minute (divide both side by 72)
15 miles = 90 minutes (multiply both sides by 90)
Step-by-step explanation:
answer - 15 miles
Answer: 28- 36t to the second power
Step-by-step explanation:
Answer:
C. Amount needed to fence around a circular garden
Step-by-step explanation:
The Circumference of a circle can be referred to as the length of the circle. It also called the perimeter of a circle.
The circumference of a circle can be defined as the distance roundabout a circle.
The circumference of a circle is calculated mathematically as:
a) 2πr or
b) πD
Where r = radius of the circle.
D = Diameter of the circle
From the above question, the situation can be modeled by circumference of a circle based on the definition that the circumference of a circle is the distance around a circle is Option C. "Amount needed to fence around a circular garden"
