Answer: The A coordinate will not be moved because it lies on the y-axis. Point B will be placed at (2,1) as point C will be placed at (4,2).

Step-by-step explanation:

The simple way to work these types of questions out is to use the rule for reflections :

Reflection over the Y-axis- (x,y)--> (-x,y)

Solve for x! 37m,12m,5xm

Answer:

$\Huge\boxed{x=7}$

Step-by-step explanation:

Hello there!

The first thing we want to do is find the measure of the large leg

To do so we use the Pythagorean theorem which says $a^2+b^2=c^2\\$

where a and b are legs and c is the hypotenuse

we want to find b given the hypotenuse and short leg

so $b^2=c^2-a^2$

all we have to do is plug in a ( a = short leg so a would equal 12) and c ( c = hypotenuse so c would equal 37)

$b^2=37^2-12^2\\37^2=1369\\12^2=144\\1369-144=1225\\b^2=1225\\\sqrt{b^2} =b\\\sqrt{1225} =35\\b=35$

so the longer leg is equal to 35

35=5x

divide each side by 5

5x/5=x

35/5=7

we're left with x=7

10. In the drawing below, the dashed line segment represents the distance across a pond. What is the actual

GarryVolchara [31]

Answer:

D. 20 yds

Step-by-step explanation:

✔️First, find the distance across across the pond on the drawing using Pythagorean Theorem:

Distance across = √(6² + 8²) = √100

Distance across on drawing = 10 in.

✔️Next, find the actual distance using the scale of 1 inch : 2 yards:

The scale implies that,

1 inch represents 2 yards

Therefore:

10 inches will represent = 10 × 2 = 20 yards
