What value of m satisfies the equation<br> m-2=2-m?<br>

zhuklara [117]

Hello,

Answer: m = 2

Step-by-step explanation:

m - 2 = 2 - m

⇔ m - 2 + m = 2 - m + m

⇔ 2m - 2 = 2

⇔ 2m - 2 + 2 = 2 + 2

⇔ 2m = 4

⇔ 2m/2 = 4/2

⇔ m = 2

When converting from inches to feet , the measurement in inches,m, of an object varies directly with its measurement in feet, f,

aleksandr82 [10.1K]

Answer:

m = 12f

m/12 = f

Step-by-step explanation:

The conversion from inches to feet involves a constant factor of variation which is 12. Inches is a smaller unit while feet are obtained by dividing the inches with 12.

As we know,

1 foot = 12 inches

Given in the question:

m = measurement in inches

and

f= measurement in feet

Hence the equation will be:

m = 12f

m/12 = f ..

What is the equation of the line that goes through (-5,0) and (-4,4)

Tasya [4]

Answer:

$y=4x+20$

Step-by-step explanation:

To write an equation, use the slope-intercept equation:

$y=mx+b$

M is the slope and b is the y-intercept.

First, find the slope by using the slope formula for when you have two points:

$\frac{y(2)-y(1)}{x(2)-x(1)}=\frac{rise}{run}$

Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:

$(-5,0)(-4,4)\\(-5(x1),0(y1))\\(-4(x2),4(y2))\\\\\frac{4-0}{-4-(-5)}$

Simplify parentheses (two negatives make a positive) and simplify:

$\frac{4-0}{-4+5}\\\\\frac{4}{1}=4$

The slope, m, is 4. Insert this information into the equation:

$y=4x+b$

Now, take one of the points and insert into the slope-intercept formula:

$(-5,0)\\(-5(x),0(y))\\\\0=4(-5)+b$

Solve for b, the y-intercept. Simplify multiplication:

$0=-20+b$

Add 20 to both sides and simplify:

$0+20=-20+20+b\\20=b\\b=20$

The y-intercept, b, is 20. Insert this value into the equation:

$y=4x+20$

Done.

A piece of cloth is required to completely cover a solid object. The solid object is composed of a hemisphere and a cone surmoun

Otrada [13]

Answer:

▶(B) 463.39 m²

<h3>Step-by-step explanation:</h3>

$\space$

Surface area of hemisphere = 2πr²

=> 2×22/7× (7)² = 308 m²

☯<u>For calculating the surface area of a cone we need to calculate its slant height,</u>

$\sf{ \leadsto \: 1 = \sqrt{49 + 1} = \sqrt{50 \: } m}$

$\space$

$\sf{ \leadsto \: \pi \ r1 = \frac{22}{7} \times 7 \times \sqrt{50} = 463.39 \: {m}^{2} }$

$\: \:$

Hope it helps!

Have a great day! :)
