Answer:
y = -1/9x - 18
Step-by-step explanation:
Using the equation of line
y - y_1 = m(x - x_1)
y = mx + C
First first the slope of the equation
y = 9x - 4
Note: if two lines are perpendicular, their slope will be negative reciprocal
Slope = 9, but because it is perpendicular
m = -1/9
Using the equation
y - y_1 = m(x - x_1)
With the point (-9,-17)
x_1 = -9
y_1 = -17
y - (-17) = -1/9(x - (-9)
y + 17 = -1/9(x + 9)
y = -1/9(x + 9) - 17
Open the bracket.
y = (-x -9)/9 - 17
Lcm is 9
y = -x -9 - 153 / 9
y = -x - 162 / 9
Let's separate
y = -x/9 - 162/9
y = -x/9 - 18
y = -1/9x - 18
Therefore, the equation of the line is y = -1/9x - 18
Answer:
28 blue marbles
Step-by-step explanation:
since the ratio s 7/4, we have to make 49/x=7/4. 7 times 7 is 49, so 4 times 7 must be x. 4 times 7 is 28, so there are 28.
Answer:
A
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6, thus
sum = 180° × 4 = 720°
Thus each interior angle = 720° ÷ 6 = 120° and therefore
3x = 120 ( divide both sides by 3 )
x = 40 → A
Answer:
<h2><em><u>126</u></em></h2>
Step-by-step explanation:
<em>In</em><em> </em><em>number</em><em> </em><em>4</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>figure</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>parallelogram</em><em>, </em>
<em><u>So</u></em><em><u>,</u></em>
Base of the parallelogram = 14
Height of the parallelogram = 9
<em><u>Therefore</u></em><em><u>, </u></em>
Area of the parallelogram = <em><u>Base</u></em><em><u> </u></em><em><u>×</u></em><em><u> </u></em><em><u>Height</u></em><em><u> </u></em>
= 14 × 9
= 126
<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>figure</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>question</u></em><em><u> </u></em><em><u>no</u></em><em><u>.</u></em><em><u> </u></em><em><u>4</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>12</u></em><em><u>6</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
