Using proportions, it is found that the coordinates of point B are given as follows:

A. (1.6, 0).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Point B is 3/4 of the way from AB to AC, hence:

B - A = \frac{3}{4}(C - A)

The points are:

  • A(-2,-3).
  • B(x,y).
  • C(3,1).


Then, to find the x-coordinate:

x + 2 = \frac{3}{4}(3 + 2)

x + 2 = 3.6.

x = 1.6.

For the y-coordinate:

y + 3 = \frac{3}{4}(1 + 3)

y + 3 = 3

y = 0.

Hence option A is correct.

1) A rectangle has the lengths shown <br> Find the perimeter of the rectangle.
maks197457 [2]

Hi there! :)

\large\boxed{P = 32cm}

Find the perimeter by solving for y.

We know that a rectangle contains two pairs of parallel and congruent sides, therefore:

5y - 1 = 2y + 8

We can solve for y using this expression. Begin by subtracting 2y from both sides:

5y - 2y - 1 = 2y - 2y + 8

3y - 1 = 8

Add 1 to both sides:

3y - 1 + 1 = 8 + 1

3y = 9

Divide both sides by 3:

y = 3

Recall that the perimeter of a rectangle is:

P = 2l + 2w

Plug in the given expressions for the side lengths to find one equation:

P = 2(5y - 1) + 2(y - 1)

Simplify by distribution:

P = 10y - 2 + 2y - 2

Combine like terms:

P = 12y - 4

Plug in the solved value of y into this equation:

P = 12(3) - 4

P = 36 - 4

P = 32 cm.

Which of these is a point-slope equation of the line that is perpendicular to y-25 = 2(x - 10) and passes through (-3, 7)?
nydimaria [60]

Answer:

B. y-7 = 1/2(x+3)

Step-by-step explanation:

The coordinates in the question must be inverted (so -3 would become +3 and +7 would become -7)

We know that the line would be perpendicular when (x+3) is preceded by -2

You can double check this by going to a website that graphs equations and overlapping the lines.

Find the zeros of the polynomial p(x) 5-10x​
Charra [1.4K]

Answer:

Step-by-step explanation:

The given polynomial is :

p(x) = 5-10x​

We need to find the zeros of the above polynomial. To find it, put p(x) = 0

5-10x​ = 0

Subtract 5 from both sides

5-10x​-5=0-5

-10x=-5

or

10x=5

Divide both sides by 10.

x = 0.5 = 1/2

Hence, the zeros of the polynomial is 1/2.

Given that f(x) = 4x√3x + 3 and g(x) = 2√x+1, find (f/g)(x)
Tresset [83]

Answer:

2x\sqrt{3}.

Step-by-step explanation:

\frac{f}{g}(x)=\frac{4x\sqrt{3x+3}}{2\sqrt{x+1}}=\frac{2*2*x*\sqrt{3}*\sqrt{x+1}}{2*\sqrt{x+1}}=2x\sqrt{3}.
