The base formula for this equation can be represented as;
y=a√(x-h)+k <-- now substitute in the values
y=3√(x+1)+7
Just for your information;
a: vertical stretch/compression of the graph of √x, along with direction
h: translates the function to the left/right
k: translates the function upwards/downwards.
So, for something to be a function see that we want one x value to correspond to only one y value. Solving for y here gives us:
So we see that for every x, there are actually two y values output, so it is not a function.
Answer: $19
Step-by-step explanation: We know Giana earned $10 for shoveling. We know she makes $2 for every inch of snow on the ground. She shoveled 4.5 inches.
To find how much money she got from shoveling 4.5 inches, simply multiply $2 by 4.5
$2.00 x 4.5 = $9 from shoveling 4.5 inches of snow.
Now add $9 to the initial value of $10
$10 + $9 = $19 earned in total.
The answer is 55. 8 times 6 is 48, and then 48 plus 7 is 55.
