Answer: A) y = 7x - 22

Explanation: First of all, we know it cannot be D, because if the answer was D, the slope would have to be 14. Next, to find the value of b (the y intercept) we have to do 7(3) and we will then get 21. We then must subtract 21 from -1 and get the slope of -22. The reason we subtract is because we must make the x value 0, and since it is 3, we go backwards. Hope this helped!

rewrite 1/2 x 1/2 as an exponential expression with a base of 2

Answers

Answer:

2^-2

Step-by-step explanation:

According to the properties of integer exponents, 1/a^n = a^-n.

So 1/2 x 1/2 = 1/2^2 = 2^-2.

1/2 x 1/2 can be rewritten as the exponential expression 2^-2.

Edmentum answer

The expression 1/2 × 1/2 can be written as 2⁻² in the exponential form with the base 2.

What are Expressions?

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expression is 1/2 × 1/2.

We have to write the expression in an exponential form with the base 2.

1/2 × 1/2 = (1/2)²

             = 1 / 2²

We have the rule for exponentiation 1 / aᵇ = a⁻ᵇ

1/2 × 1/2 = 2⁻²

Hence the exponential form of the given expression with the base 2 is 2⁻².
