Leo drew a line that is perpendicular to the line shown on the grid and passes through point (F. G). Which of the following is t

tensa zangetsu [6.8K]

The equation of the perpendicular line drawn by Leo is $y-G=\dfrac{-1}{2}(x-F)$ . Option C is the correct answer.

<h3>How to determine the equation of a line?</h3>

A line is drawn perpendicular to the line shown in the image. The perpendicular line passes through the coordinate point (F,G).

The slope of the line from the graph is-

$m=\dfrac{y-intercept}{x-intercept}\\\\\\m=2$

Therefore, the slope of the perpendicular line is $\dfrac{-1}{2}$ .

Also, it is being given that Leo's line is passing through the coordinate point .

So, the equation of the Leo's line is-

$y-G=\dfrac{-1}{2}(x-F)$

Thus, the equation of the perpendicular line drawn by Leo is .

$y-G=\dfrac{-1}{2}(x-F)$

A quarter of the sum of a number and 20 is equivalent to 30. Find the number.

Alisiya [41]

Answer:

X = 100

Step-by-step explanation:

X + 20 over 4 = 30

1/4x + 5 = 30

-5 -5

1/4x = 25

multiply both sides by 4

x = 100

Eghh I'm so bad at Algebra >.< Help? The length of a rectangle is 9.7 cm more than 4 times the width. If the perimeter of

lina2011 [118]

L = 4w + 9.7
2l + 2w = 91.4
2(4w + 9.7) + 2w = 91.4
8w + 19.4 + 2w = 91.4
10w = 72
w = 72/10 = 7.2 cm
l = 4(7.2) + 9.7 = 38.5

Dimension = 38.5 by 7.2

Let x be the number of days for which the costs are the same, then
110 + 46x = 70 + 54x
54x - 46x = 110 - 70
8x = 40
x = 5
Therefore, it will take 5 days for the cost to be the same.

The whole number 4 is equivalent to what percent?

Zarrin [17]

This would be 400%. To get a percent you multiply the number by 100. For example, .62 x 100 equals 62%.
