2.2x+3y=15.25 <br>4.6x+2.1y=18.325<br>USING ELIMINATION<br>SHOW WORK PLEASE
Artist 52 [7]

-4.6(2.2x+3y=15.25) = -10.12x - 13.8y = -70.15

2.2(4.6x+2.1y=18.325) = 10.12x - 4.62y = 40.315

simplify

-4.62y = -29.835

divide both sides by -4.62 to isolate y

y= 6.46

2.2x + 3 (6.46) = 15.25

2.2x + 19.38 = 15.25

subtract 19.38 to both sides

2.2x = -4.3

divide 2.2 to both sides

x= -1.95

I hope that this helped :)

HELP FAST PLEASE I'LL MARK YOU BRAINLIEST What is the slope of a line perpendicular to the line whose equation is x+2y=14. Fully
sashaice [31]
Turn it into slope-intercept form.
2y = -x + 14
y = -x/2 + 7
The slope is -1/2.
Perpendicular lines have slopes that are opposite reciprocal, so the slope of the perpendicular line is 2.

1. What is the radius<br> (1 Point)<br> 11 cm
mr_godi [17]

Given that we need to determine the radius of the circle.

<u>Radius:</u>

By definition of radius of circle, the radius is the  length of the line which is drawn from the center of the circle to any point on the circle.

From the figure, we need to determine the radius of the circle.

As, we can see that, the distance from the center of the circle to the point on the circle is 11 cm.

Since, we know that, the radius is the distance from the center of the circle to the point on the circle then, the radius of the given circle is 11 cm

Thus, radius of the circle is 11 cm.
