2x + y - (x + y) = 3z - 6z 
--------------------------------------------------------
<span>x = -3z </span>
------------------------------------------

<span>(-3z, 9z) </span>
 ----------------------------------
<span>(x,y,z) = (-3z, 9z, z) 
</span>--------------------------
<span>x = -3z, y = 9z
---------------------
There for the answer is </span><span>(-3z, 9z) </span>

Q # ..18 I need your help
andriy [413]

Answer: y = -5x - 3.


Explanation:


When you know the slope and the y-intercept you can directly write the slope-intercept equation of the line.


The slope-intercept equation of the line has the form: y = mx + b, where m is the slope and b is the y-intercept.


Here you know m = -5 and b =  -3, hence you just have to substitute those values in the general slope-intercept form, which is:

  • y = -5x - 3.

That equation represents the line, which means tha every point in the line will be an ordered pair of the function. For example:


  x            y = -5x - 3

- 10          -5(-10) - 3 = 50 - 3 = 47

  0            0 - 3 = - 3 (this is the y-intercept)

10            -5(10) - 3 = - 50 - 3 = - 53

Choose whether the expression is a result of multiplying
vladimir1956 [14]

Answer:

neither

Step-by-step explanation:

Take out 5 as a common factor. It will be easier to look at.

5(5c^2 + 11c + 6)

5(5C +6 )(c + 1 )

Now you can put the 5 inside.

(25c + 30)(c + 1) is one answer.

(5c + 6)(5c + 5) is another.

The answer is multiplying binomials. There is nothing that that is squared and the answers are not conjugates. They are two binomials multiplied together.

Vikki [24]

Answer:

14.4 kN

Step-by-step explanation:

cantilever balcony 2m wide 0.2m deep and 1.5m length.

= 2 x 0.2 x 1.5

= 0.6 m³

weight of the balcony

= 0.6 x 24

= 14.4 kN.

therefore the max shear 14.4 kN and is acting at support.
