Answer:

= 4y

Step-by-step explanation:

y - ( - 3y)

we know that,

( - ) \times ( - ) = ( + )

so,

y - ( - 3y) \\ y + 3y \\  = 4y

hope this helps

brainliest appreciated

good luck! have a nice day!

Find the area of the largest trapezoid that can be inscribed in a circle of radius 1 and whose base is a diameter of the circle.
ki77a [65]
<span>Answer:
        let x = shortest base of the trapezoid
   A = h (x/2 + r) = âš(r² - (x/2)²) (r + x/2)
   = âš(1 - (x/2)²) (1 + x/2) .... if r = 1
   dA/dx = (2 - x - x²) / (2âš(4 - x²))
   = 0 at x = 1 .... which is a relative maximum because d²A/dx² < 0
   A = (3/4) âš3</span>

Find the coordinates of the reflection: B (5, 4) is reflected over the line x=1
zepelin [54]

Answer:

The coordinates of point B' are (-3, 4) ⇒ C

Step-by-step explanation:

If the point (x, y) reflected across the line x = a, then a is the x-coordinate of the midpoint of the segment joining the point and its image

∵ The coordinates of point B are (5, 4)

∴ x = 5 and y = 4

∵ The point B is reflected over the line x = 1

→ From the rule above

∴ a = 1

∵ The rule of the midpoint is M = (\frac{x1+x2}{2} , \frac{y1+y2}{2})

→ The point B is (x1, y1) and the point B' is (x2, y2)

∵ a is the x-coordinate of the midpoint of segment BB'

∴ a = \frac{x1+x2}{2}

∵ x1 = 5 and x2 = x

→ Substitute the value of a, x1 and x2 in the rule above

∴ 1 = \frac{5+x}{2}

→ Multiply both sides by 2

∵ 2 = 5 + x

→ Subtract 5 from both sides

∴ 2 - 5 = 5 - 5 + x

∴ -3 = x

∴ The x-coordinate of B' = -3

→ y-coordinate of B' = y-coordinate of B because the reflection across

   x = a does not change the y-coordinate

∴ y-coordinate of B' = 4

∴ The coordinates of point B' are (-3, 4)

Jonah collects rainwater in a large barrel that weighs 30 pounds. When there are 10 gallons of water in the barrel, the total we
Serjik [45]
The first thing we are going to do for this case is define variables.
 We have then:
 x: number of gallons of water
 y: total weight
 We then have an equation of the form:
 y-yo = m (x - xo)&#10;
 Where,
 m = (y2 - y1) / (x2 - x1)&#10;
 Substituting values:
 m = (196.8 - 113.4) / (20 - 10)&#10;&#10;m = 8.34
 We choose an ordered pair:
 (xo, yo) = (10, 113.4)&#10;
 Substituting values:
 y-113.4 = 8.34 (x - 10)&#10;
 Rewriting:
 y = 8.34x - 83.4 + 113.4&#10;&#10;y = 8.34x + 30
 Answer:
 
y = 8.34x + 30
