Please help! (I'll give brainliest to the first right answer.)
-BARSIC- [3]

Answer:

1. initial point is (2, 4)

reflected point is (-2, 4)

the coordinates are similar because they involve the same numbers, however, with the reflection across the Y axis, the X point became negative.

2. initial point is (2, 4)

reflected point is (2, -4)

again, same numbers but the X value becomes negative

Hope this helps!

How many cubes with side lengths of
liq [111]

The number of 1/3 cm-cubes that would fill the rectangular prism is approximately 20 cubes.

<h3>What is the Volume of a Cube?</h3>

Volume = a³, where a is the side length.

<h3>What is the Volume of a Rectangular Prism?</h3>

Volume = lwh

Given the following:

  • a = ⅓ cm
  • l = 4/2 cm = 1/2 cm
  • w = 2/2 cm = 1 cm
  • h = 3/2 cm

Volume of the rectangular prism = (1/2)(1)(3/2)

Volume of the rectangular prism = (1/2)(1)(3/2) = 0.75 cm³

Volume of the cube = (⅓)³ = 0.037 cm³

Number of cubes that would fill the prism = 0.75/0.037 ≈ 20 cubes.

The equation of the line passing through the points (−10, 0) and (−8, 20) can be expressed as y = mx + b. Give the value of b.
weeeeeb [17]

Given are the two points (-10,0) and (-8,20), and equation of the line as y=mx+b.

We can plug the given values in the equation as follows :-

0 = -10m + b .........equation(1)

20 = -8m + b .........equation(2)

Subtracting equation(1) from equation(2)

20 - 0 = (-8m + b) - (-10m + b)

20 = -8m + b + 10m - b

20 = 10m - 8m

20 = 2m

m = 10

Plugging m=10 in the equation(1)

0 = -10(10) + b

0 = -100 + b

b = 100

So final answer is b = 100.
