Which of the following is a linear equation?

1 answer:

4 0

2x - 3y = 7 can be rewritten as y = 2/3x - 7/3, therefore, the equation that is a linear equation is: C. 2x - 3y = 7.

<h3>What is a Linear Equation?</h3>

A linear equation is expressed in the slope-intercept form as y = mx + b.

2x - 3y = 7, rewritten in slope-intercept form would be:

-3y = -2x + 7

y = -2x/-3 + 7/-3

y = 2/3x - 7/3

m = 2/3 and b = -7/3

Therefore, the equation that is a linear equation is: C. 2x - 3y = 7.

Which regular polygon has a rotation of 240 degree to carry the polygon onto itself?

kirza4 [7]

The regular polygon that has a rotation of 240 degrees to carry the polygon onto itself is the equilateral triangle.

<h3>The missing part of the question</h3>

<u>Options</u>

Equilateral triangle

Octagon

Rectangle

Pentagon

<h3>How to determine the polygon?</h3>

A polygon that can carry itself onto itself after a rotation of 240 degrees must obey the following rule:

Angle of rotation = 360/Sides

Next, we test the options:

Option (a) equilateral triangle

Angle of rotation = 360/3

Evaluate

Angle of rotation = 120

Next, we list the multiples of 120

120, 240, 360.....

See that 120 is a factor of 240.

This means that the equilateral triangle would be rotated onto itself when rotated by 240 degrees.

A ruler measures length to the nearest 0.25 inches. Which is the most appropriate way to report length using this ruler?

Dafna11 [192]

Judging by the given information i would say A. it seems like there should be a diagram to accompony. But, c is wrong because its not rounded to .25
D. is just an outliar
it's between A and B. a diagram would answer that. it depends which the point is closer to. I'm saying A. because it sounds like the exercise wants you to use the decimal.

This is the answer unless the 2/4 is meaning divide the two if thats the case the answer is 48+√2 over 8

the figure is made of up of a cone and a cylinder, to the nearest whole number what is the approximate volume of this figure. PL

Deffense [45]

The total volume is the sum of volume of cone and volume of cylinder.

Volume of cylinder = πr²h
π = 3.14
r = 4/2 = 2 mm
h = 2 mm

So, volume of cylinder equals:

$3.14 *(2)^{2}*2 =25.12$ mm³

Volume of cone = $\frac{1}{3} \pi r^{2}h$
π = 3.14
r = 2 mm
h = 3 mm

So, volume of cylinder equals:

$\frac{1}{3}*3.14* (2)^{2}*3=18.84$ mm³

Thus, total volume of the figure = 25.12 + 18.84 = 43.96 mm³

How would I solve (-2-2i)(-4-3i)(7+8)

siniylev [52]

$(-2-2i)(-4-3i)(7+8)=\\
15(-2-2i)(-4-3i)=\\
15(8+6i+8i-6)=\\
15(2+14i)=\\
30+210i$
