Answer:
y = - 2x + 4
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (- 1, 6) into the partial equation
6 = 2 + c ⇒ c = 6 - 2 = 4
y = - 2x + 4 ← equation of line
Answer:
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
There are 6 rectangular flower gardens each measuring 18 feet by 13 feet in a rectangular city park. The area of each garden is
Area = 18 × 13 = 234 ft²
Since there are 6 gardens, the total area covered by the 6 gardens is
6 × 234 = 1404 ft²
The rectangular park measures 70 feet by 160 feet. The total area of the park is
Area = 70 × 160 = 11200 ft²
The number of square feet of the park that is not used for flower gardens is
11200 - 1040 = 10160 ft²
The formula for determining the perimeter of a rectangle is
2(length × width)
Total number of feet covered by rectangular city park is
2(70 + 160) = 460 ft
Number of feet covered by the 6 rectangular gardens is
6[2(18 + 13)] = 372 ft
The number of feets not used for flower gardens is
460 - 372 = 88 feet
120 / 72 = 1 2/3
5/3 x 6/1 = 30/3 = 10

Shape 1: TRIANGLE
Formula: A = 1/2 x bh
1/2 x (10)(5) = 25
AREA: 25 square yards
Shape 2: RECTANGLE
Formula: A = lw
(12)(10) = 120
AREA: 120 square yards
Sum (ADD)
25 yd^2 + 120 yd^2 = 145 yd^2
The area of the composite figure is 145 yd^2

<span>12 is what percent of 30:
Ok let’s try to analyze the problem.
First, this problem is asking us to determine what the percentage of 12 out of
30 is.
=> 30 is equals to 100% of the number
=> 12 is the X% of the number.
Solutions:
=> 12 / 30 = 0.4
now, multiply this with 100% to get the percentage rate of this decimal number.
=> .4 * 100% = 40%
Therefore, 1 is 40% of the number 30.</span>
