Answer:
The point (2, -1 ) is not on the graph of the line.
Step-by-step explanation:
3x–4y–12=0 
3*2 - 4*(-1) - 12= 0
6 + 4 - 12 =0
10 - 12 = 0
- 2 = 0 , false, so the point (2, -1 ) is not on the graph of the line.
 
        
                    
             
        
        
        
Answer:
The first blank is 81 +9=x-1
+9=x-1
The second blank is 9x+3=x^2-1
Step-by-step explanation:
For the first part, you must set up the equation (9x+3)^2       then you must multiply the exponent to the inside exponents  +
+ next, simplify.
 next, simplify.
81 +9=x-1
+9=x-1
For part two, set up equation.  Then simplify 9x+3=
 Then simplify 9x+3= 
 
        
             
        
        
        
Answer:
Aldo's shirt was made of 13/15 meters of fabric.
Step-by-step explanation:
We need to add these fractions. However, in order to do so, we need to find the LCM, which in this case, is 15.
1/5 + 2/3 =
3/15 + 10/15 =
13/15
This fraction is also written in simplest form. Therefore, Aldo's shirt was made of 13/15 meters of fabric.
Hope this helps! :D
