Which expression is equivalent ?

Answer: $2.11

Step-by-step explanation:

A customer brings a bag of chips with a regular price of $2.19 to the register which is marked down 10% the price to pay will be:

= $2.19 - (10% × $2.19)

= $2.19 - $0.219

= $1.971

After a 7% sales tax on the final price, the amount paid by the customer will be:

= $1.971 + (7% × $1.971)

= $1.971 + $0.13797

= $2.11

Step-by-step explanation:

The roots of the function g(x) are -4 and 1.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the roots of the given function, we need to find the values of x that make the function equal to zero.

This can be done by factoring the function and setting each factor equal to zero.

g(x) = (x² + 3x - 4) (x² - 4x + 29)

Setting each factor equal to zero.

x² + 3x - 4 = 0

(x + 4)(x - 1) = 0

x² - 4x + 29 = 0

This quadratic has no real roots since its discriminant is negative.

The roots of g(x) are the values of x that satisfy either of these equations, which are:

x = -4 or x = 1

Thus,

The roots of the function g(x) are -4 and 1.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Fig.2 is harder to drive on. Because the gravity is pulling you to opposite direction. Thats why there's no such roads on hills, they always go round and round to make the roads easier to drive on.

2. Fig.2 will build up more speed, because gravity will pull unidirectional from you.

3. (Realitiscally) no, DONT TEXT AND DRIVE. Even if you are driving on a flat ground.

4. No, of course not. In situation no.1 and 2, you can drive like that because there is gravitational pull coming from x and y axis. But from situation no.4, the gravitational pull is from y axis only, so it will only pull you down.

Hey there!

The answer to your question is Crew A

We can find this by first finding the unit rate, or acres per hour. We can divide the amount of acres by the amount of hours.

Crew A : 6/7.5 = 0.8 acres per hour

Crew B : 4.5/6 = 0.75 acres per hour

With the data above, we can see that Crew A is faster.

Hope it helps and have an amazing day! Remember, You've got this!

Step-by-step explanation:

(4 × 2) + (4 × 0.3) = 9.2 grams

Answer: C) x = 2

2^{2x + 2} = 2^{3x}

Since both terms (above) have the same base, set the exponents to be equal:

2x + 2 = 3x (Rearrange to solve for x)

x = 2

∴ x = 2

Yes Noah's method will always work

Step-by-step explanation:

Noah's method states that:

To find 20% of a number he divides the number by 5. For example, 20% of 60 is 12.

Noah's method will always work because:

20% = 20/100

Simplifying 20/100 to the least fraction = 20/100 = 1/5

20% of x = 1/5 × x

= x/5 = x ÷ 5

Applying this to the examples

20% of 60 = 1/5 × 60

= 60/5 = 12.

Therefore, Noah's method will always work.

Mathematical domain is all numbers, as all numbers can be multiplied by 4. However, this is not reasonable as negative lengths don't exist, so the reasonable domain would be all positive numbers.

Answer:

Step-by-step explanation:

This warm-up prompts students to carefully analyze and compare quadratic expressions. In making comparisons, students need to look for common structure and have a reason to use language precisely (MP7, MP6). The activity also enables the teacher to hear the terminology students know and how they talk about characteristics of the different forms of expressions.

As students discuss in groups, listen for rationales that are based on the structure of the expressions. Select those students or groups to share their thinking during class discussion.

Launch

Arrange students in groups of 2–4. Display the expressions for all to see. Give students 1 minute of quiet think time and then time to share their thinking with their small group. In their small groups, ask each student to share their reasoning about why a particular item does not belong, and together find at least one reason each item doesn't belong.
