Answer:
Step-by-step explanation:
slope of required line=5
point is (-1,0)
reqd. eq. of line is 
y-0=5(x-(-1))
y=5(x+1)
y=5x+5

Answer:
Hey there!
y=3/4x shows that the y-value is always 3/4 of the x-value.
Thus, if x is 4, y is 3. It always fits the 4:3 ratio.
The ordered pairs that satisfy this equation are: 28:21 and 16:12

The answer is:  " 
11 " .
____________________________________________________            →     " 
x  =  11  "  .
____________________________________________________Explanation:____________________________________________________Set up the ratio/ proportion as a fraction:
6 cm / 48 cm = 5 cm / (3x + 7) ; 
→ The "cm" units cancel out; since:  "cm/cm = 1 " ; 
→ The "6/48" = "(6 ÷ 6) / (48 ÷ 6) =  " 1/8 " ; 
→ Rewrite as:  

 ;
Now, we can "cross-multiply" :
__________________________________________________<u>Note</u>:  
 ;  

 ; 
              {b

 ;  d 

} .
__________________________________________________ As such:       
    1 * (3x + 7) = 8 * 5 ; 
   →  3x + 7 = 40 ; 
Subtract "
7" from each side of the equation:
   →  3x + 7 − 7 = 40 <span>− 7 ; 
</span>
to get:  
   → 3x = 33 ; 
Now, divide each side of the equation by "
3" ; 
   to isolate "x" on one side of the equation; & to solve for "x" ; 
   →  3x / 3 = 33 / 3 ; 
to get: 
____________________________________________________     →    " 
x = 11 " .
____________________________________________________   →   
The answer is:  "
 11 " .

Answer:
41.5
Step-by-step explanation:
So you see the first five lines are for 19 dollars.
Multiply 7.75 by 3 since there are 3 additional lines. (Answer: 23.25)
Add 19 and 23.25 together. (Answer: 42.25)
