Answer:
<h3>x = 5</h3>
Step-by-step explanation:
f(x) = 2(x + 6)
f(x) = 22
thereofre we have the equation:
2(x + 6) = 22 <em>use distributive property</em>
2x + 12 = 22 <em>subtract 12 from both sides</em>
2x = 10 <em>divide both sides by 2</em>
x = 5
Y=total cost. x=# of days.
y=17x+130.
substitute in 9 for x days.
y=17(9) +130 = 153 +130 = 283
y=$283
Answer:
Steady rate
Step-by-step explanation:
It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
Answer:
3x
Step-by-step explanation:
-(x-1) +5 = 2(x+3) - c
C is the unknown term
Distribute the negative sign and the 2
-x+1 +5 = 2x+6 -c
Combine like terms
-x+6 = 2x +6-c
Solve for c
Add x to each side
-x+x +6 = 2x+x +6-c
6 = 3x+6 -c
Add c to each side
6+c = 3x +6 -c+c
c+6 = 3x+6
Subtract 6 from each side
c+6-6 = 3x+6-6
c = 3x
When c = 3x, the two sides of the equation are equal, and the solutions are infinite.
12 cups of flour is 4 times the quantity in the recipe, so 4 times as much brown sugar is needed, 4×2=8 cups of brown sugar.
