Y=5x-5 (0,-5) (1,0) (-5,0)
-5=5(0)-5
-5=-5
0=5(1)-5
0=5-5
0=0
0=5(-5)-5
0=-25-5
0=-30
the following point that does not lie on the graph of y=5x-5 is point (-5,0)
9. √105 is irrational (105 is not the square of an integer) Its value is near +10.
-4 is an integer (and rational)
4/3 is a rational number
Smallest to largest, these are -4, 4/3, √105.
10. The nearest square less than 14 is 9 = 3×3. The nearest square greater than 14 is 16 = 4×4. 14 is closer to 16 than to 9, so we expect 4 to be the integer closest to its square root. (√14 ≈ 3.74, closer to 4 than to 3.)
11. The numbers are in the same order; only the location of parentheses has changed. The property that lets you do that with addition is the associative property.
Answer:
(-5/2, -33/4)
Step-by-step explanation:
-b/2a
-5/2 = x
f(-5/2) = (-5/2)^2 + 5(-5/2)-2 = -33/4
