Answer:
Yes. This equation defines y as function of x.
Step-by-step explanation:
Step 1:
Solve the equation for y (this puts the equations in terms of y)
2x+y=8 becomes
y = 2x - 8
This is a linear equation, which is a funtion.
*Another way to solve this is to look at the graph. Graphing this equation gives us a line. Use the vertical line test to see if it's a function.
To pass the vertical line test (VLT), there can only be one y value to each x value along the graph. If it passes the VLT, the equation is a function.
If it fails the VRT, the equation is not a function.
Millimeter is the smallest and blood cells are really small. I’d say something smaller though, if that’s an option.
Answer:
distribute -5 and -4
Step-by-step explanation:
-5(-6x-9y)-4(-10x+7y)
(30x + 45y) - (- 40x + 28)
30x + 45y + 40x - 28
45y + 70x - 28
Answer:
girls = 125
boys = 87
Step-by-step explanation:
Total number of students in the 8th grade class = 212
Let g represent girls and b represent boys
Number of girls, g = 2b -49
Note that boys and girls in the class give a total of 212
So,
g + b = 212 ....eq 1
Slot in the value of g in the equation
2b - 49 + b = 212
2b + b - 49 = 212
3b - 49 = 212
Add 49 to both sides
3b - 49 + 49 = 212 + 49
3b = 261
Divide both sides by the coefficient of b which is 3
b = 87
Now that we've found the number of boys, let's find that of girls
We will slot in the value of b in eq 1
g + 87 = 212
Subtract 87 from both sides
g + 87 - 87 = 212 - 87
g = 125
So the number of boys is 87 and the number of girls is 125
Answer:
The graph of y=log(x)+4 is the graph of y=log(x) translated 4 units up.
Step-by-step explanation:
The translation ...
y = log(x -h) +k
translates the log function right h units and up k units.
The only description matching the equation is ...
The graph of y = log(x)+4 is the graph of y = log(x) translated 4 units up.
