2.20 ÷ 5 = .44
.44 × 7 = $3.08 for seven stamps
Answer:
Graph 1
Step-by-step explanation:
The reason for the answer being graph one is because the equation |x| = 1 means the absolute value of x could either be 1 or -1 , resulting in points rather than lines as the equation is already solved rather then being less than or greater than.
Hope this helps!
1. y=8.9
SOLUTION
y=11 - 2.1
=8.9
2. 2x - 5y - 8 = 0
HOPE THIS HELPS :))
Step-by-step explanation:
We have cartisean points. We are trying to find polar points.
We can find r by applying the pythagorean theorem to the x value and y values.

And to find theta, notice how a right triangle is created if we draw the base(the x value) and the height(y value). We also just found our r( hypotenuse) so ignore that. We know the opposite side and the adjacent side originally. so we can use the tangent function.

Remeber since we are trying to find the angle measure, use inverse tan function

Answers For 2,5

So r=sqr root of 29

So the answer is (sqr root of 29,68).
For -3,3


Use the identity

So that means

So our points are
(3 times sqr root of 2, 135)
For 5,-3.5


So our points are (sqr root of 37.25, 35)
For (0,-5.4)

So r=5.4

So our points are (5.4, undefined)
B because 67 is not equal to 96
E because 67 is less than 96
