Answer:

The equation of line is y=-\frac{9}{4}x+12

Step-by-step explanation:

We have been given the equation of line as y=\frac{4}{9}x-2

Comparing this equation with the slope intercept form of a line y = mx+b , we get

m=\frac{4}{9}\\\\ b=-2

We know that the slopes of two perpendicular lines are negative reciprocal of each other.

Therefore, the slope of the required line is

m=-\frac{1}{4/9} =-\frac{9}{4}

Now, this line passes through the point (4,3)

Hence, using the point slope form of the line, the required equation is

y-y_1=m(x-x_1)\\\\y-3=-\frac{9}{4} (x-4)\\\\y=-\frac{9}{4}x+12

Therefore, the equation of line is

y=-\frac{9}{4}x+12

Y - y₁ = m(x - x₁)
 y - 3 = -2¹/₄(x - 4)
 y - 3 = -2¹/₄(x) + 2¹/₄(4)
 y - 3 = -2¹/₄x - 9
   + 3            + 3
       y = -2¹/₄x - 6

Find the missing length ‘x’
givi [52]

Answer:

x = 13

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = \frac{1}{2} h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here A = 55, h = 5. b₁ = x, b₂ = 9, then

\frac{1}{2} × 5 × (x + 9) = 55

2.5(x + 9) = 55 ( divide both sides by 2.5 )

x + 9 = 22 ( subtract 9 from both sides )

x = 13

vova2212 [387]

Answer:

  36 ft by 16 ft

Step-by-step explanation:

To solve this problem, you need to find dimensions of a rectangle such that the perimeter is 104 ft and the area is 576 ft. The perimeter is twice the sum of length and width, so the sum of length and width is 52 ft.

The area is the product of length and width, so if w represents the width, we have ...

  w(52 -w) = 576

  w² -52w = -576 . . . . . eliminate parentheses, multiply by -1

  w² -52w +26² = 26² -576 . . . . . .  complete the square

  (w -26)² = 676 -576 = 100

  w = 26 ±√100 =  {16, 36}

If the width is the short dimension, it is 16 feet. Then the length is 36 feet.

When a negative number multiplies a negative number, it becomes positive

since it is multiplication, just multiply across, you do not need same denominators

5/8 x 16/25 = 80/200

80/200 = 40/100 = 20/50 = 2/5

2/5 is your answer

hope this helps
