Justify each step used to simplify the expression. 1. 3x+ 2y− 2x+ 2 = 3x− 2x+ 2y+ 2

Answers

Answer 1

Step-by-step explanation:

We have to simplify the given expression:

1. 3x+2y-2x+23x+2y−2x+2

Combining the like terms,we get the second step as

2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)

Now, taking 'x' common from the first two terms, we get third step as:

3. (3-2)x+2y+2(3−2)x+2y+2

Now, simplifying the expressions among the like terms, we get fourth step as:

4. x+2y+2x+2y+2

A furniture store offers free setup and delivery services to all points within a 25-mile radius of its warehouse distribution center. If you live 20 miles east and 14 miles south of the warehouse, will you incur a delivery charge? JUSTIFY YOUR ANSWER!

I am confused. I don't know what to dooo

Answers

Answer:

No

Step-by-step explanation:

you can make a right triangle with 20 and 14. To find the hypotenuse, you add

20² + 14² = h²

400+196 = h²

596<25²

596<625

which is true.

Yes , the person will get free delivery as the person lives in the 25 mile radius.

What is a Right Angled Triangle ?

A right triangle is a triangle with one of its side as 90  degree.

It is given that the person lives 20 miles east and 14 miles south of the warehouse.

The warehouse gives free delivery for people in 25-mile radius

The distance between the warehouse and the house ≤ 25 mile

To determine the distance a right angled triangle is considered

The base is 20 and height is 14 , hypotenuse = ?

Hypotenuse ≤ 25

[tex]\rm \sqrt { 20^2 + 14^2}[/tex] ≤ 25

24.43 ≤ 25

So , Yes the person will get free delivery as the person lives in the 25 mile radius.

Find the area of the region bounded by the y-axis, x-axis and the line y=-2x+4.

Answers

Answer:2

Step-by-step explanation:y = 0 : 0 = -2x + 4 → x = -2 is the x-intercept. Similarly, when the line crosses the y-axis, the x-coordinate at this point will be zero and substituting x = 0 into the equation will give us the y-intercept. x = 0 : y = 0 + 4 → y = 4 is the y-intercept.

Ginger spins the spinner below and rolls the number cube. What is the probability that Ginger's spinner will land on 3 and she will roll a 4?

Answers

I’m not sure if I’m doing this right but I think 1/42

Because there is 7 numbers on the spinner and 6 on the cube so 7 times 6 is 42
Count how many sides there are on the spinner and then make a fraction to answer it. Also a cube doesn’t have just 3 sides.

i’ve had this question before, it’s C

Trevor is having trouble understanding how the degree of a nonzero constant is 0. Use the expression 3x^0 to help explain this concept to Trevor.

A. The degree of a monomial is the sum of the number of its variables. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Therefore, the degree of the nonzero constant 3 is 0.
B. The degree of a monomial is the coefficient of its variable. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Since the expression has no variables, the degree of the nonzero constant 3 is 0.
C. The degree of a monomial is always zero. Therefore, the degree of the nonzero constant 3 is 0.
D. The degree of a monomial is the sum of the exponents of its variables. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Therefore, the degree of the nonzero constant 3 is 0.

plz hury i am on a test

Answers

Answer:

72

Step-by-step explanation:

18*4

12*6

8*9

Answer: LCD = 72

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/8, 1/12, 7/18

For the denominators (8, 12, 18) the least common multiple (LCM) is 72.

LCM(8, 12, 18)

Therefore, the least common denominator (LCD) is 72.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 9/9 = 9/72

1/12 = 1/12 × 6/6 = 6/72

7/18 = 7/18 × 4/4 = 28/72
