<span>If you imagine a straight line, with -9 all the way on the left, then mark along the line in one number increments until you get up to 7, you will find that in total the line is 16 segments in total. Mathematically, this is a question of absolute value, ie absolute value of -9 = +9, and therefore 9 + 7=16.</span>
Answer:
C is correct, D might be correct if you forgot 000 at the end of the question.
Step-by-step explanation:
005 = 5x1 so A is incorrect
945 = 9x100 + 4x10 + 5x1 so B is incorrect
15.859 = 1x10 + 5x1 + 8/10 + 5/100 + 9/1000 + so C is correct
973.001 = 9x100 + 7x10 + 2x1 + 1/1000 so D is incorrect
Use the y-intercept formula: y=mx+b
Plug in one of the points for x and y
Using that, solve for either x or y
Answer:
f(-5) = -43
Step-by-step explanation:
Step 1: Define
f(x) = -2x² + 7
f(-5) is x = -5
Step 2: Substitute and Evaluate
f(-5) = -2(-5)² + 7
f(-5) = -2(25) + 7
f(-5) = -50 + 7
f(-5) = -43
Answer:
A square
Step-by-step explanation: A square is a parallelogram. This is always true. Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides.
