Evaluate 2(10 - d) + f, when d = 7 and f = -3. a. -2 b. 3 c. 9 d. 20

B.3

Step-by-step explanation:

2(10 - d) + f

d = 7 and f = -3

Substitute these value in

2(10 - 7) + -3

2 * (3) -3

6 -3

3

Put the values of d = 7 and f = -3 to the expression 2(10 - d) + f

Use PEMDAS:

PParentheses first

EExponents (ie Powers and Square Roots, etc.)

MDMultiplication and Division (left-to-right)

ASAddition and Subtraction (left-to-right)

2(10 - 7) + (-3) = 2(3) - 3 = 6 - 3 = 3

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
