1. x= 1  y= 6
2. x=-2  y=0

answer:

Option 1

Step-by-step explanation:

Area = ½× base × height

= ½ × 34 × 6.3

= 107.1 yd²

To solve this, we need to find the length of side FE using the Pythagorean Theorem, a^2 + b^2 = c^2.  Sides FD and DE are both 3 units long.
3^2 + 3^2 = c^2
9 + 9 = c^2
18 = c^2
sqrt18 = sqrtc^2
4.2 ≈ c
Now, we will add all three sides.  4.2 + 3 + 3 = 10.2.  The correct answer is C, 10.2 units.

That symbol represents a source of DC, usually a battery.

The zig-zag line represents a resistor, and the two little circles
connected by a short line represent a switch in the closed position.,

A) A source of electrical energy.

Explanation:

The Symbol of two long lines, two short lines represents and, a positive and negative sign is a voltage source, which is a two-terminal device capable of maintaining a constant voltage.

The voltage generates an electric field, which makes the electrons inside the conductive cables to move along the circuit from the positive sign to the negative sign.

$What is the approxmate area of the figure plz look at picture and answer right will give brainlist$

Using elimination method to solve the y-value
2x + 3y = 20
-2x + y   = 4
+ (add)
4y = 24

The first mistake is when she added 20 + 4, it's supposed to be 24 not 16

4y = 24
y = 24/4
y = 6

Using subtitution method to solve the x-value
2x + 3y = 20
2x + 3(6) = 20
2x + 18 = 20
2x = 2
x = 1

The correct solution to the system is (1,6)

answer:

107.1 yards squared

Step-by-step explanation:

Area of triangle=base*height/2

34 yds*6.3 yds/2=107.1

A=107.1 yards squared

9. CheddaDsk says:

3^2 + 3^2 = 9+ 9 = 18
FE = √18 = 4.2

P = 3 + 3 + 4.2 = 10.2

answer
C . 10.2 units

Since the diamater of the two half circles is 5 ft. the area of those combined would be: pi * r ^2 = pi * 2.5^2 = 19.6349540849 (almost 20)

And the area of the rectangle would be 5 * 15 = 75

So.. the approximate area of the figure would be 75 + 20 = 95
