Step 1: Define
f(x) = x/3 - 2
f(42) is x = 42
Step 2: Evaluate
Substitute in x: f(42) = 42/3 - 2Divide: f(42) = 14 - 2Subtract: f(42) = 12Could someone please explain what an "infinite" and "finite" number is?
I'd also appreciate examples of both. :)

Answer:
v = 4
Step-by-step explanation:
u + at = v
a (-2) multiplied by t (3) = -6
-6 + u (10) = 4
Answer:
[tex]v=4[/tex]
Step-by-step explanation:
[tex]v=u+at[/tex]
Substitute u=10, a=-2 and t=3 in above equation
[tex]v=10-2(3)[/tex]
[tex]v=4[/tex]

Need help on this please
Answer:
It's D
Step-by-step explanation:
2t - 30([tex]\frac{1}{5}[/tex]) = 20
2t - [tex]\frac{30}{1}[/tex] ([tex]\frac{1}{5}[/tex]) = 20
2t - [tex]\frac{30}{5}[/tex] = 20
2t - 6 = 20
2t - 6 + 6 = 20 +6
2t = 26
[tex]\frac{2t}{2}[/tex] = [tex]\frac{26}{2}[/tex]
t = 13

a || b . Find the value of the star.
Record your answer as a decimal. Round to the nearest hundredth if necessary.
Answer:
The star equals 96
Step-by-step explanation:
The star will be equal to 5x-14 because they are vertically opposite.
The two exterior angles are supplementary. Set up the equation
5x - 14 + 3x + 18 = 180 Combine the terms on the left.
8x + 4 = 180 Subtract 4 from both sides
8x = 180 - 4 Combine
8x = 176 Divide by 8
x = 176 / 8
x = 22
===================
5x - 14
5*22 - 14
96

The diameter of the sphere is 12cm and the radius is half of the diameter, so the radius would be 6cm
Solve for s.
-7 = 7s + 28
Answer:
s= -5
Step-by-step explanation:
have a good day
Answer:
Step-by-step explanation:
subtract 28 on both sides that will cancel the 28
-35 = 7s, divide both sides by 7, this cancels the 7
- 5 = s
s=-5
|-1|=-1 is this true
Answer:
False
Step-by-step explanation:
The question is asking for the absolute value of -1. The absolute value is the distance of a number from 0. Think of a number line. -1 is one place away from 0, so the absolute value of -1 is 1. Therefore, the statement is not true.

What is the difference between a rational and irrational number?
Answer:
Rational numbers are the numbers which are integers and fractions
Irrational numbers are the numbers whose expression as a fraction is not possible
Examples of Rational Number
1/9 – Both numerator and denominator are integers.
7 – Can be expressed as 7/1, wherein 7 is the quotient of integers 7 and 1.
√16 – As the square root can be simplified to 4, which is the quotient of fraction 4/1
0.5 – Can be written as 5/10 or 1/2 and all terminating decimals are rational.
0.3333333333 – All recurring decimals are rational.
Examples of Irrational Number
√2 – √2 cannot be simplified and so, it is irrational.
√7/5 – The given number is a fraction, but it is not the only criteria to be called as the rational number. Both numerator and denominator need to integers and √7 is not an integer. Hence, the given number is irrational.
3/0 – Fraction with denominator zero, is irrational.
π – As the decimal value of π is never-ending, never-repeating and never shows any pattern. Therefore, the value of pi is not exactly equal to any fraction. The number 22/7 is just and approximation.
0.3131131113 – The decimals are neither terminating nor recurring. So it cannot be expressed as a quotient of a fraction.

Try graphing at desmos com
Step-by-step explanation:
Write two multiplication equations that compare the number of blue fish 16 to the number of yellow fish 4
Answer:
b = 4y
y = 1/4 * b
Step-by-step explanation:
Number of Blue fish = 16
Number of yellow fish = 4
Let:
Blue fish = b
Yellow fish = y
b = 4y
b = 4(4)
b = 16
From ;
b =4y
y = b/4
y = 1/4 * b
Hence,
y = 1/4 * 16
y = 16/4
y = 4
