Answer:

x = -4y + 5/2

Step-by-step explanation:

step 1: 2x +8y + -8y = 5 + -8y

2x = -8y+ 5

step 2: divide both sides by 2

2x /2 = -8y+5/2

x= -4 + 5/2

Which set of polar coordinates describes the same location as the rectangular coordinates (-3,3)
Readme [11.4K]
To convert from rectangular coordinates (x,y) to polar coordinates (r, θ), the following equations should be used:

r = sqrt( x^2 + y^2)
<span>θ = tan^-1 (y/x)
</span>
Substituting (-3,3) accordingly to the equations, we obtain r equal to 3*sqrt(2) and θ equal to -π/4. Thus, the polar coordinates equivalent to (-3,3) is (3*sqrt(2), -π/4).

Find the distance between each pair of points
dolphi86 [110]

Answer: the correct answer is 20

Step-by-step explanation:

The formula for determining the distance between two points on a straight line is expressed as

Distance = √(x2 - x1)² + (y2 - y1)²

Where

x2 represents final value of x on the horizontal axis

x1 represents initial value of x on the horizontal axis.

y2 represents final value of y on the vertical axis.

y1 represents initial value of y on the vertical axis.

From the graph given,

x2 = - 7

x1 = 5

y2 = - 7

y1 = 9

Therefore,

Distance = √(- 7 - 5)² + (- 7 - 9)²

Distance = √(- 12²) + (- 16)²

= √(144 + 256) = √400

Distance = 20

A grocery clerk put only packages of flour tortillas and packages of corn tortillas on a shelf . The ratio of the number of pack
Artist 52 [7]

Answer:

The number of packages of flour tortillas is a 9 multiple.

Step-by-step explanation:

Given there are only packages of flour tortillas and packages of corn tortillas on the shelf.

Let the number of flour tortillas be x and the number of corn tortillas be y

therefore the total number of packages are x+y.

Given the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16.

which means \frac{y}{x+y} = \frac{7}{16}

16y = 7x+7y

7x=9y

x=\frac{9y}{7}

since both x and y are integers y is in the form of 7k where k∈N.

x=9k

Therefore x is a 9 multiple.
