Answer: 4
Step-by-step explanation:
The degree is the highest exponent , in which in this problem it is 4. The 3x counts as an exponent of 1 because the variable x is 1, and the 2 counts as an exponent of zero. Which means the degree is 4.
Answer:
C. 20
Step-by-step explanation:
Take a value from the x-axis (Width) and the y-axis (Height) and substitute them into the equation. I'll use the point (5, 4).
Height = Constant/Width
4 = Constant/5 (Given)
20 = Constant (Multiplied 5 on both sides)
The answer is D: 5p = 120
The scale factor is 1/2 or .5 because 200*.5=100 and 100*.5=50 and so on
42 and 14
explanation:
x+y = 56
x = 3y
Substitute for x in the first equation:
x + y = 56
x = 3y
3y + y = 56
Combine like terms:
4y = 56
Divide both sides by 4:
y = 14
So if y = 14, and x = 3y, then x = 42.
Now substitute for both x and y in both of the original equations to prove they are the correct values.
x + y = 56
x = 42
y = 4
42 + 14 = 56
56 = 56
x = 3y
x = 42
y = 14
42 = 3*14
42 = 42
So the two numbers, x and y, are 42 and 14.
