True [87]

The distance between the coordinates in meters is 138.92m

Using the distance formula to calculate the distance between the coordinates as shown:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\$

Given the coordinate points C(-5, 8) and V (7, 1)

Substitute the given coordinates into the formula

$D = \sqrt{(7+5)^2+(1-8)^2} \\D = \sqrt{(12)^2+(-7)^2} \\D = \sqrt{144+49} \\D = \sqrt{193} \\D=13.892 units$

Given that 1 unit = 10metres

D = 13.892 * 10

D = 138.92 meters

Hence the distance between the coordinates in meters is 138.92m

Tomás is using this recipe to make

Aloiza [94]

Step-by-step explanation:

For 2 people it uses 1 1/3 cups

1 1/3 = 1.33

So for 4 people Tomas will use

1 1/3 + 1 1/3 = 2.66 or 2 2/3 cups

Simplify: (2x2 − 9x + 3) + (−7x2 + 4x − 2)

Leokris [45]

Combine like terms
2x^2 + -7x^2 = -5x^2
-9x + 4x = -5x
3 + -2 = 1
put back together
-5x^2 - 5x +1
