Alex17521 [72]

Answer:

Grayson has to walk 1.7 miles across the field.

Step-by-step explanation:

We have drawn the diagram for your reference.

Given:

Grayson usually walks 1.5 miles west on the side walks

According to Diagram we can say;

CA = 1.5 miles

Also Given:

Grayson also walks 0.8 miles north on the sidewalks

So According to Diagram we can say;

BA =0.8 miles

Now we need to find number of miles Grayson have to walk across the field.

According to diagram we can say;

We have to find CA.

Assuming the diagram  to be right angled triangle.

We can find CA using Pythagoras theorem.

{CA}^2 = {CB}^2+{BA}^2

Substituting the given values we get;

{CA}^2 =1.5^2+0.8^2 = 2.25 +0.64 =2.89

Taking square root on both side we get;

\sqrt{{CA}^2} = \sqrt{2.89} \\\\CA = 1.7 \ mi

Hence Grayson has to walk 1.7 miles across the field.

Write an equation of a line perpendicular to x = -7 and passes through the<br> point (4,9).
AlladinOne [14]

Answer:

y = 9

Step-by-step explanation:

The line x = -7 is a vertical line, so the perpendicular line will be horizontal.

Horizontal lines have a slope of 0.

Using this slope and the point given, plug them into y = mx + b to solve for b and create the equation

y = mx + b

9 = 0(4) + b

9 = b

Plug this and the slope into the equation:

y = mx + b

y = 0x + b

y = 9

So, y = 9 is the equation

Select the correct answer. two triangles, abc and cde, share a common vertex c on a grid. in triangle abc, side ab is labeled 4x
LekaFEV [45]

The value of x based on the information given in the triangle is D. x = 1.

<h3>How to compute the value?</h3>

From the information given, it stated that the triangles are similar.

In this case, both triangles have side 4 and 5. Therefore, we are to find the last side. This will be:

4x - 1 = x + 2

Collect like terms

4x - x = 2 + 1

3x = 3

x = 3/3

x = 1

Therefore, the correct option is D.
