Answer:

{ x > 1 } [ -10, 10, -5, 5 ]

Step-by-step explanation:

13. To graph this we will draw a vertical line at 1 on the horizontal axis.

The lne will be a dashed line because the inequality operator does not contain an "or equal to" clause.

We will shade t the right side of the line because the inequality operator contains "greater than" clause.

14. Intersepted as : y < ( -1 ) x 2 x X + 4

Solution : 2x + y -4 < 0

15. Solution : -2x + 3y -6 > 0

Evaluate:

(-1) X 2 X x + 3y > 6

Multiply the terms:

-2x + 3y > 6

Solution: -2x + 3y -6 > 0

A box of cereal states that there are 87 calories in a 3-4cup serving. What is the unit rate for calories per cup? How many ca

riadik2000 [5.3K]

Answer: for 2 cups, There are 232 Calories.

Step-by-step explanation:

Step 1

Let the calories in one cup be represented as C

Therefore

3/4 x C = 87 calories

C = 87 X 4 / 3 = 116

unit rate is 116 calories per cup.

Step 2- Solving the number of calories in 2 cups

1 cup serving = 116 calories

2 cups servings = 116 x 2= 232 calories

Rewrite the form In exponential form: Log100 = x

andrey2020 [161]

Answer:

$10^x=100$

Step-by-step explanation:

You know how subtraction is the opposite of addition and division is the opposite of multiplication? A logarithm is the opposite of an exponent. You know how you can rewrite the equation 3 + 2 = 5 as 5 - 3 = 2, or the equation 3 × 2 = 6 as 6 ÷ 3 = 2? This is really useful when one of those numbers on the left is unknown. 3 + _ = 8 can be rewritten as 8 - 3 = _, 4 × _ = 12 can be rewritten as 12 ÷ 4 = _. We get all our knowns on one side and our unknown by itself on the other, and the rest is computation.

We know that $3^2=9$ ; as a logarithm, the exponent gets moved to its own side of the equation, and we write the equation like this: $\log_3{9}=2$ , which you read as "the logarithm base 3 of 9 is 2." You could also read it as "the power you need to raise 3 to to get 9 is 2."

One historical quirk: because we use the decimal system, it's assumed that an expression like $\log1000$ uses base 10, and you'd interpret it as "What power do I raise 10 to to get 1000?"

The expression $\log100=x$ means "the power you need to raise 10 to to get 100 is x," or, rearranging: "10 to the x is equal to 100," which in symbols is $10^x=100$ .
