Segment AB has endpoints on the coordinate grid where A is (- 18, 5) and B is (- 4, 5) Point Z is located exactly 1/8 of the dis
fenix001 [56]

Given:

Endpoints of segment AB are A(- 18, 5) and B(- 4, 5).

Point Z is located exactly 1/8 of the distance from A to B.

To find:

The value of the x-coordinate of point Z.

Solution:

Point Z is located exactly 1/8 of the distance from A to B.

AZ:AB=1:8

AZ:ZB = AZ:(AB-AZ)= 1:(8-1) = 1:7

It means point Z divided segment AB in 1:7.

Using section formula, the x coordinate of point Z is

x-coordinate=\dfrac{mx_2+nx_1}{m+n}

x-coordinate=\dfrac{1(-4)+7(-18)}{1+7}

x-coordinate=\dfrac{-4-126}{8}

x-coordinate=\dfrac{-130}{8}

x-coordinate=-16.25

Therefore, the required x-coordinate of point Z is -16.25.

Solve the following proportion for x. 3/13 = x/5 Round your answer to the nearest tenth.
anastassius [24]

To solve, isolate the x. Cross multiply

3/13(13)(5) = x/5(5)(13)

3(5) = (13)x

Simplify

13x = 15

Isolate the x. Divide by 13.

13x/13 = 15/13

x = 15/13

x = 1.2

1.2 is your answer

hope this helps

Answer:

I will try:

Step-by-step explanation:

Note: ∈ means 'belongs to the set of' and <em>R</em> is 'the set of all real numbers'

Inequality:

- Domain is: x ∈ <em>R</em>

- Range is: x ≥ -2

Set:

-Domain is: {x| x ∈ <em>R</em>}

- Range is: {y| y ≥ -2}

Interval:

- Domain is: (-∞,∞)

- Range is: [-2, ∞)

g(x) is stretched by a factor of 4 and translated 2 units down.
