First lets simplify the equation by removing the parenthesis

m + n + 3 + m + n + 4

Gather the like terms

(m + m) + (n + n) + (3 + 4)

Now simplify it add 3 + 4 so it can be 7

Answer: C) 2m + 2n + 7 or the third option.

16. Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

il63 [147K]

Answer:

Given equation are:

$y = -\frac{1}{4}x+8$ ......[1]

$-2x+8y = 4$ .....[2]

The two lines are parallel lines then their slopes will be equal.

When two lines are perpendicular then, the slope of lines are the negative reciprocals of each other.

Now, Equation of a line is in the form of y =mx+b where m is the slope of the line.

Slope $(m_1)$ of equation of line in [1] is;

$y = -\frac{1}{4}x+8$

then;

$m_1= -\frac{1}{4}$

Slope $(m_2)$ of equation of line in [2];

$-2x+8y = 4$

Add both sides 2x we get;

-2x + 8y + 2x = 2x + 4

Simplify:

8y = 2x +4

Divide both sides by 8 we get;

$y = \frac{1}{4} x + \frac{1}{2}$

then;

$m_2 = \frac{1}{4}$

Therefore, the given two lines are neither parallel nor perpendicular.

Find the slope between the points (−3,−5) and (10,-5)

balandron [24]

Answer:

Step-by-step explanation:

$m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$m = \dfrac{-5 - (-5)}{-3 - 10}$

$m = \dfrac{0}{-13}$

$m = 0$

If the scale factor of a scale drawing is greater than one, the scale drawing is larger than the actual object

galina1969 [7]

False, for example, if the scale factor is 2, the scale drawing would still be smaller because it would be twice as smaller than the actual object.

Find the volume of a right circular cone that has a height of 11.7 m and a base with a

yulyashka [42]

Answer:

volume of the cone = 247.98 cubic meter

Step-by-step explanation:

Height of the cone= 11.7 m

Circumference= 9 m

Radius= 9/2= 4.5 m

Volume of the cone;

= $\pi r^2\frac{h}{3}$

As, $\pi =\frac{22}{7}= 3.14$

Putting the values in the formula:

Volume of the cone is:

$=3.14*(4.5*4.5)*\frac{11.7}{3} \\\\=3.14*(4.5*4.5)*3.9\\\\=3.14*20.25*3.9\\\\=3.14*78.98\\\\=247.98m^3$

The volume of the cone is 247.98 cubic meter
