The easiest thing to do is to convert it all to the smallest units.
3 yard = 108 inches
10 ft = 120 inches
17 inch
108 +120 + 17 = 245 inches
Note that the 2nd equation can be re-written as y=8x-10.
According to the second equation, y=x^2+12x+30.
Equate these two equations to eliminate y:
8x-10 = x^2+12x+30
Group all terms together on the right side. To do this, add -8x+10 to both sides. Then 0 = x^2 +4x +40. You must now solve this quadratic equation for x, if possible. I found that this equation has NO REAL SOLUTIONS, so we must conclude that the given system of equations has NO REAL SOLUTIONS.
If you have a graphing calculator, please graph 8x-10 and x^2+12x+30 on the same screen. You will see two separate graphs that do NOT intersect. This is another way in which to see / conclude that there is NO REAL SOLUTION to this system of equations.
Answer:
8.0<x<8.5
Step-by-step explanation:
Answer:
55
Step-by-step explanation:
substitute 2 into j
so do 18 x 2= 36
36+19=55
j=55
The fixed fee is $5.75. This part of the equation is called the constant. There are no variable being multiplied or divided meaning it is not being grouped in any way. This tells us it stands alone and represents a number that is non -changing or fixed.
