Hello,
Let's assume top left  corner: A
top right corner : B
Bottom right corner: C
Bottom left corner :D

M= middle of [CD]

ABM is a triangle rectangular isocel:

(3√2)²+(3√2)²=y²
==>y²=2*9*2
==>y²=36
==>y=6

The triangle BCM is rectangular with MB=3√2, MC=y/2=3
x²+3²=(3√2)²
==>x²=9*2-9
==>x²=9
==>x=3

X = 16 - 4y<br> 3x + 4y =8 <br> substitution method
8_murik_8 [283]

Answer:

i think x = -4, y = 5

Step-by-step explanation:

x = 16 - 4y

3x + 4y = 8

3(16 - 4y)+4y = 8

48-12y+4y = 8

48-8y = 8

48-8 = 8y

40 = 8y

5 = y

so

x = 16 - 4y

x = 16 - 4(5)

x = 16 - 20

x = -4

Can you help me please.
Kamila [148]

9514 1404 393

Answer:

  a.  (-1/2, 5)

Step-by-step explanation:

The coefficients of x have opposite signs, so the x-terms can be eliminated by adding the two equations.

  (2y -12x) +(3y +12x) = (16) +(9)

  5y = 25 . . . . . . simplify

  y = 5 . . . . . . . . .divide by 5

This matches only answer choice A.

__

<em>Check</em>

The other part of answer choice A is x = -1/2. We can test this to make sure it works:

  2(5) -12(-1/2) = 16

  10 + 6 = 16 . . . . . . true, the selected answer works OK

Approximate square root 18 to the tenths and plot on number line
GenaCL600 [577]

Since 18 does not have a number that when multiplied by itself equal 18, then it will be a decimal number.  You can tell the closest whole number by seeing what is the closest square.  In this case we know that 16 is 4 times 4 and the next one would be 5 times 5 to equal 25, so the whole number would be 4.  

Now, the easiest way to do this is to get you calculator and take the square root of 18 to get 4.242641.  The problem wants it to be to the nearest tenth so 4.2 is your answer.  On a number line, if it is in four parts, you will plot it just before the first little line.

Hope this helps!  If you are using more small lines in you number line, comment me below and I would be happy to lead you in the right direction.
