What is the equation of the line that passes through the points four over 5 , and one over five and then one half , and three ov

Scorpion4ik [409]

Your answer is y = -(13/3)x + 11/3. I have put the brackets to show that the entire fraction is negative, they do not do anything else.
First we need to find the slope of the line using the equation (y2 - y1)/(x2 - x1), so we get (3/2 - 1/5)/(1/2 - 4/5). To make this easier, I did each subtraction separately:
3/2 - 1/5 = 15/10 - 2/10 = 13/10
1/2 - 4/5 = 5/10 - 8/10 = -(3/10)
And then we need to divide 13/10 by -(3/10), so:
13/10 ÷ -(3/10) = 13/10 × -(10/3) = -(130/30) = -(13/3), which is our slope.
Then, we can write the equation y = -(13/3)x + c, and substitute in coordinates:
3/2 = (-13/3 × 1/2) + c
3/2 = -(13/6) + c
c = 11/3
So the final equation is y = -(13/3)x + 11/3.
I hope this helps!

Describe the transformation f(x) = Vx+ 1 - 5 in words.

ivanzaharov [21]

Answer:

The translation is 1 unit to the left and 5 units down

Step-by-step explanation:

The explanation is given below;

Given that

The transform function is $f(x) = \sqrt{x+1} - 5$

It can be seen that

The parent function is

$f(x) = \sqrt{x}$

After that

The parent function would be transform 1 units to the left $\sqrt{x+1}$

And afterwards it would be transform in 5 units down $\sqrt{x+1} - 5$

The parent function $f(x) = \sqrt{x}$ would be translate in 1 unit to the left and 5 units down

What is the volume of the entire figure?

ch4aika [34]

This is just a shape with a peace of it cut out so if we imagine how would this figure be before it was cut. it would give us an 4×12×6 cuboid (we can use that) so first, lets caculate the volume of the bigger cuboid

$6 \times 12 \times 4 = 288$
then we need to caculate the valume of the two smaller cuboids.
$4 \times 4 \times 4 = 64$
$2 \times 4 \times 12 = 96$
by subtracting the valume of the bigger cuboid from our two smaller ones we will have the valume of the three-dimensional figure.
65+96=160
288-160=128
