Select ALL equations that are functions.
functions can't be with exponents -
the correct answers are b,c,d
Answer:
These 3:
y = 2, y = 1/2x + 5, y = x
Step-by-step explanation:
Y can't be squared that would give a sideways function, that doesn't pass the vertical line test
Question 2
The value of a car y (in thousands of dollars) can be approximated by the model y = 24(0.83)* where t is the number of years since the car was new. Identify the percent increase or decrease in the car's value. Estimate when the car's value will be $6500.
Select the appropriate percent increase or decrease, and when the car will be worth $6500.

4x^4+12x^2+8 solve ✖➖➕➗
Step-by-step explanation:
Simplifying 4x4 + -12x2 + 8 = 0 Reorder the terms: 8 + -12x2 + 4x4 = 0 Solving 8 + -12x2 + 4x4 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4'. 4(2 + -3x2 + x4) = 0 Factor a trinomial. 4((1 + -1x2)(2 + -1x2)) = 0 Factor a difference between two squares. 4(((1 + x)(1 + -1x))(2 + -1x2)) = 0 Ignore the factor 4.
Subproblem 1
Set the factor '(2 + -1x2)' equal to zero and attempt to solve: Simplifying 2 + -1x2 = 0 Solving 2 + -1x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x2 = 0 + -2 -1x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -1x2 = -2 Divide each side by '-1'. x2 = 2 Simplifying x2 = 2 Take the square root of each side: x = {-1.414213562, 1.414213562}
Subproblem 2
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1
Subproblem 3
Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1
Solution
x = {-1.414213562, 1.414213562, -1, 1}

a recipe calls for 3 1/2 teaspoons of mustard seeds, 4 cups of tomato sauce, and 6 3/4 cups of beans, you use 2 2/3 cups of tomato sauce. how many teaspoons of mustard seeds don you need? how many cups of beans do you need?
Answer:
For a recipe call,
Number of teaspoons of mustard seeds =
Number of cups of tomato sauce = 4
Number of cups of beans =
For 4 cups of tomato sauce, the number of teaspoons of mustard seeds needed =
For 1 cup of tomato sauce, the number of teaspoons of mustard seeds needed =
For cups of tomato sauce, the number of teaspoons of mustard seeds needed =
Hence, for cups of tomato sauce, the number of teaspoons of mustard seeds needed is .
For 4 cups of tomato sauce, the number of cups of beans needed =
For 1 cup of tomato sauce, the number of cups of beans needed =
For cups of tomato sauce, the number of cups of beans needed =

How many times smaller is 2 × 10 to the negative 8th power than 4 × 10 to the negative 7 power?
A. 20
B. 200
C. 0.2
D. 2,000
Answer:
A. 20Step-by-step explanation:
How many times smaller is 2 × 10⁻⁸ than 4 × 10⁻⁷ ?
Rewrite the numbers with the same power of 10:
2 × 10⁻⁸ and 40 × 10⁻⁸Divide the second number by the first, cancel the powers as they are same:
40/2 = 20Correct option is A
The values are
2×10-⁸ and 4×01^{-7}Divide to find how many times smaller
4/2×10^{-7+8}2(10)20timesRewrite the following equation in slope-intercept form. 4x - y =12
