Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:
x=1.25, y=2.5
Step-by-step explanation:
x = # of soft tacos
y = # of double deckers
3x+3y=11.25 *4 => 12x+12y=45
4x+2y=10 *-3 =>-12x-6y=-30
6y=15
y=2.5
4x+2(2.5)=10
4x+5=10
4x=5
x=1.25
Answer:
D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.
Step-by-step explanation:
Let us assume x = selling price of each soccer ball
y = daily profit earned from selling of soccer balls
Given that
Y=
where,
a = -6
b = 100
c = -180
Now we have to applied the formula which is as follows
x
x^1 = -2.05285
Now
x^2
x^2 = 14.6138
Based on this the option D is most appropriate as per the given situation
Answer:
y = 1/2x + 5
Step-by-step explanation:
The first thing you should know about a perpendicular line is that the slope is the opposite reciprocal. So, the slope is 1/2. This is your current equation: y= 1/2x + b. Plug in your point to the equation, it should look like this: 6 = 1/2(2) + b. 1/2 x 2 equals 1. This is what it should look like: 6 = 1 + b. Subtract 1 from both sides to get 5 = b. Go back to your original equation and plug in 5. This is your final equation: y = 1/2x + 5. Hope this helped!
