One of the rows in the table has an error and does not have the same ratio as the other rows. Which explains how to correct the
hram777 [196]
<span>Row 1 3 ft  91.44 cm
The ratio is 91.44 cm/ 3 ft = 30.48 cm/ft

</span><span>Row 2 6 ft 172.88 cm
The ratio is 172.88 cm / 6 ft = 28.81 cm/ft which ius not the same as 30.48 cm/ft.

</span><span>Row 3 7 ft 213.36 cm
</span>
<span>The ratio is 213.36 cm/ 7 ft = 30.48 cm/ft, which is the same as the first ratio.

Since 2 rows have the ratio 30.48 cm/ft, this ratio is correct. The ratio 172.88 cm / 6 ft is incorrect.

6 ft * 30.48 cm/ft = 182.88 cm

Answer: </span>
<span>B.Row 2 should show 6 feet is equivalent to 182.88 centimeters.</span>

Write the linear equation from the given information in slope intercept form (-1,3); slope=-3​
nadya68 [22]

Answer:

<h3>y = -3x</h3>

Step-by-step explanation:

The standard expression of equation of a  line in slope-intercept form is expressed as;

y = mx+c

m is the slope

c is the intercept

Given

slope m = -3

Point (x, y) = (-1, 3)

x = -1 and y = 3

Get the intercept

To get the intercept c, we will substitute the given values into the equation above to have;

y = mx+c

3 = -3(-1)+c

3 = 3 + c

c = 3-3

c = 0

Substitute m = -3 and c = 0 into the equation above;

y = mx+c

y = -3x+0

y = -3x

Hence the required linear equation is y = -3x

Identify the solution(s) of the system of equations, if any. -4x-2y=16 2y=-4x-16
Elodia [21]
-4x-2y = 16
2y = -4x-16

Get one variable alone on both equations

-4x - 16 = 2y
-4x - 16 = 2y

You'll realize that they're the same equation.
Use substitution

-4x-16 = -4x-16
0 = 0
x = all solutions

Use x = all solutions in an earlier equation to find y

-4x - 16 = 2y
SInce x can be all solutions y is also all solutions
y = all solutions
