Answer:
false
Step-by-step explanation:
<u>Step :1</u>
Given x- 2 y =5 .......(1)
put x=1 and y= -3 on left hand side of given equation
1 - 2 (-3) = 5
1 + 6 = 5
7 ≠ 5
both sides are not equal
so it is false
Y=5x-4. 5x4=20,5x-4=20
y=-20
9x2=18) 9x3=27) 9x4=36) 9x5=45) 9x6=54) 9x7=63) 9x8=72) 9x9=81) 9x10=90) Multiples of 9. Now it says 9 more than twice a number so you could do like 24 + 24 = 48 + 9 = 57 Now just do that for what ever problem you have just add the numbers together and add 9! Hope this helps! ;D
Answer:
units
Step-by-step explanation:
The given triangle is an isosceles right triangle.
This implies that, the second leg is also x units.
We use the Pythagoras Theorem to obtain:
Divide both sides by 2; to get
Take positive square root to get:
I could tell u it's not 'D' it could be 'A' or 'C', I think it's 'B'
