Jack got the expression 7x + 1 and then wrote his answer as 1 + 7x. Is his answer an equivalent expression? How do u know? Explain using extended vocabulary

Answers

Answer 1

Answer: Yes, it is an equivalent expression because even though you move two pieces of an equation it will still equal the same thing, unless there are parentheses involved.

Answer 2

Answer: 7x + 1 is composed by + 7x and + 1

1 + 7x is composed by + 1 and + 7x

So
7x + 1 = 1 + 7x

Madeline is on a diet. She exercises every day in order to lose some weight. she currently has 210 pounds. Make a graph with a number of pounds she loses and with the amount of time she takes (in months) to lose that weight.

Well,

The example I will use will be the relationship between the Celsius scale and the Fahrenheit scale.

The formula for the conversion between Fahrenheit and Celsius:

$F= (9)/(5) C+32$

We can immediately see that this is a linear equation if we substitute y for F and x for C.

$y= (9)/(5) x+32$

or

$f(x)= (9)/(5) x+32$

It is a line that has a y-intercept of (0,32), and has a slope of 9/5.

I have attached the line below.

Answers

To find perimeter all you have to do is add all numbers together, but some may be missing so you'd have to look at other numbers around the shape, so the answer to your shape is: 132 ft Hope it helps!!

Answer:

What is 6.95 to one decimal place?I know how to round to the nearest tenth but if you round this,it just goes to a whole number!

Answers

The answer is 7.0. When you want to round to the nearest tenth, you need to leave only one decimal. The second decimal is 5. So, the first decimal will be rounded to the first bigger number. In this case 6.95, the first decimal number 9 will increase to 10 which means that the number 6.95 will be rounded to a whole number: 6.95 = 7.0
