Answer:
36.45
Step-by-step explanation:
5.50 × 3 = 16.5
16.5 + 19.95 = 36.45
sorry if wrong.
hope it helps.
Answer:
1) y=-10x+50 (it's the only negative slope / going down option and it starts at x=0 y=50)
just substitute the x with a 9
y=-10*9 +50
y= -40
2) 0.5x +5 (only positive slop and starting point at x=0 is correctly 5)
we do need to substitute y this time, with 30 obviously
30 = 0.5x +5 |-5
25 = 0.5x | *2
50 = x
3) y=-2x +50 reasoning as before
substitute x with 4
y =-2*4 +50
y = -8 +50
y = 42
For this case we have the following equation:
We must find the value of the variable "x", for this:
We apply square root to both sides of the equation:
Thus, the solutions of the equation are:
Answer:
Answer:
<em>BC, BD, BQ, CB, CD, CQ, DB, DC, DQ, QB, QC, QD </em>
Step-by-step explanation:
<em>"BC, BD, BQ, CB, CD, CQ, DB, DC, DQ, QB, QC, QD"</em> Are all the possible rays on line c.
13 ( 19 - x)
Distribute 13 into the parenthesis.
13 (19) 13 (-x)
= 247 - 13x
They aren't like terms so we leave the answer as: 247 - 13x
