Short answer: It's a circle.
Argument
A parabola has a power of x on one side of the equal sign.
A circle (like this one) has variables raised to the second degree (x and y). The number in front of x^2 and y^2 is equal, usually 1.
An ellipse has x^2 and y^2 present, the numbers in front of x^2 is different from the number in front of y^2
hyperbola has a minus sign between the x^ and y^2. or between the y^2 and x^2
These are the main characteristics of each. They are not the only ones.
Answer:
Step-by-step explanation:
For this construction, you want to mark off the distance BC on two segments that are perpendicular to each other. A suitable pair of such segments is FD and FG.
The arcs intersect those segments at points that will become the vertices of the new triangle. Connecting those points will form the hypotenuse of the new triangle. The legs are already drawn as part of segments FD and FG.
4.50 per walk
At least 50
we can write an equation to solve for how many walks, w,
4.50w = 50
divide both sides by 4.50
w = 11.111...
That is, he will have to walk about 12 times to earn at least $50 when charging $4.50 for a walk with the dogs.
Hope this helps :)
Lets x is the amount of money Paul spent
y is the amount of money John spent
<span>Henry spent 3 times as much as paul = 3x
so
</span>John and paul spent $45 altogether: <span>x + y = 45
</span> john and henty spent $65 altogether: 3x+y = 65
solve the equations
3x+y = 65
x + y = 45
---------------subtract
2x = 20
x = 10
x + y = 45
y = 45 - x
y = 45 - 10
y = 35
3x = 3(10) = 30
so
Paul spent $10 (x)
John spent $ 35 (y)
Henry spent $30 (3x)
answer: John spent $ 35
double check:
$ 35 + $ 10 = $45 (<span>John and Paul spent $45 altogether)
</span>$ 35 + $30 = $65 (<span> John and Henry spent $65 altogether)</span>
