Archy [21]3 years ago
6 0

Answer:

True

Step-by-step explanation:

The answer is "True". Let me explain.

Let's say that we have a line segment which we will call AB, construct a perpendicular bisector. The following steps will be taken;

1) Draw a semi circle with its centre at point A and passing through point B.

2) Draw a semi circle with its centre at point B and passing through point A.

3) The two semicircles will intersect at two points with one being above and the other being below the straight line segment AB. Now, a line will have to be drawn that passes through those two intersecting points. This drawn line is called the perpendicular bisector for line segment AB.

Write an equivalent expression using distributive property and simplify for each question
Akimi4 [234]

Answers:

Here we have to solve each expression applying the distributive property (when necessary) and taking into account the rules related to algebraic addition:

A) 2x+10x=12x

B) -4(3x-10)+5(2-6x)=-12x+40+10-30x=-42x+50

Factoring the result with 2 as a common factor:

-42x+50=2(-21x+25)=2(25-21x)

C) 2(x-4)+x=2x-8+x=3x-8

D) -3-7(3-4x)+8x=-3-21+28x+8x=36x-24

Factoring the result with 12 as a common factor:

36x-24=12(3x-2)

Anusha needs to find a rectangular container large enough to hold a volume of 130 in.3. Which container should she use?
leonid [27]

Option C

Container with the dimensions 3 by 5 by 10 inches has a volume of 150 cubic inches, which is large enough to hold a volume of 130 cubic inches

<em><u>Solution:</u></em>

Anusha needs to find a rectangular container large enough to hold a volume of 130 cubic inches

The volume of rectangular container is:

volume = length \times width \times height

<em><u>Option A</u></em>

Container with the dimensions 2 by 5 by 10 inches

Therefore, volume is given as:

Volume = 2 \times 5 \times 10 = 100

Thus volume is 100 cubic inches

<em><u>Option B</u></em>

Container with the dimensions 3 by 4 by 10 inches

Therefore, volume is given as:

Volume = 3 \times 4 \times 10 = 120

Thus volume is 120 cubic inches

<em><u>Option C</u></em>

Container with the dimensions 3 by 5 by 10 inches

Therefore, volume is given as:

Volume = 3 \times 5 \times 10 = 150

Thus volume is 150 cubic inches

<em><u>Option D</u></em>

Container with the dimensions 4 by 2 by 10 inches

Therefore, volume is given as:

Volume=  4 \times 2 \times 10 = 80

Thus volume is 80 cubic inches

Thus Container with the dimensions 3 by 5 by 10 inches has a volume of 150 cubic inches, which is large enough to hold a volume of 130 cubic inches

What is the equation of the line that passes through (4, -1) and (-2, 3)?
Mrac [35]

Answer:

2x + 3y - 5 = 0

Step-by-step explanation:

(4 , -1)  & (-2,3)

Slope =\frac{y_{2}-y_{1}}{x_{2}-x_1}}\\\\=\frac{3-[-1]}{-2-4}\\\\=\frac{3+1}{-6}\\\\=\frac{4}{-6}\\\\=\frac{-2}{3}

m = -2/3;   (4 , -1)

y - y1 = m(x - x1)

y - [-1]= \frac{-2}{3}(x-4)\\\\y + 1 =\frac{-2}{3}x -4*\frac{-2}{3}\\\\y + 1 =\frac{-2}{3}x+\frac{8}{3}

Multiply the equation by 3

3y + 3 = -2x + 8

3y = -2x + 8 - 3

3y = -2x + 5

2x + 3y - 5 = 0
