Answer:
Dilations just make a shape bigger or smaller
Step-by-step explanation:
Answer:
<u>The numbers are -61 and -68</u>
Step-by-step explanation:
x = Smaller number
y = Larger number
x + y = - 129
y = x + 7
*********************************
x = - 129 - y
*********************************
Substituting x and solving for x and y, we have:
y = -129 - y + 7
2y = - 129 + 7
2y = -122
y = -122/2
y = -61 ⇒ x = -68
<u>The numbers are -61 and -68</u>
So in these problems, we're dealing with absolute value. Absolute value is the real amount of the number, or it's real place value without a negative sign.
Part A: if the absolute value of X was 17, then X could equal -17 or 17.
Part B: |x+9|=15. We know that 6+9=15, so X could equal -6 or 6.
Part C: |x-10| ≤ 13. We know that 23-10 is 13. So 23 would be the greatest value of X. Then, for the smallest value of X, if we insert -3 in the equation to take the place of the variable, we get |-3-10|=13. So -3 would be the smallest value of the equation. X≤ 23 and X≥-3.
