Answer:
Step-by-step explanation:
- 8x + 44 ≥ 60
Subtract 44 from both sides
- 8x + 44 - 44 ≥ 60 - 44
- 8x ≥ 16
Divide both sides by -8 and flip the inequality sign
-8x/-8 ≤ 16/-8
x ≤ -2
x = { ......... -4,-3,-2}
2) -4x + 50 < 58
Subtract 50from both sides
-4x + 50 -50 < 58- 50
-4x < 8
Divide both sides by -4 and flip the inequality sign
-4x/-4 > 8/-4
x > -2
x= {-1, 0 , 1 , 2....... }
F(x) = -2 * x + 8
f(-1.8) = -2 * (-1.8) + 8 = 3.6 + 8 = 11.6
Answer: The correct answer is x=5
Step-by-step explanation:
x=2−5−−75=2−5−5i3=−2.5000−4.3301i
x=2−5+−75=2−5+5i3=−2.5000+4.3301i
x=5

Answer: 1- quadrant 1 or top right
2- quadrant 4 or bottom right
3-quadrant 3 or bottom left
|TJ| = sqrt((0 - (-4))^2 + (5 - (-2))^2) = sqrt(4^2 + 7^2) = sqrt(65)
|SE| = sqrt((3 - (-1))^2 + (10 - 3)^2) = sqrt(4^2 + 7^2) = sqrt(65)
|JD| = sqrt((1 - 0)^2 + (-1 - 5)^2) = sqrt(1^2 + (-6)^2) = sqrt(37)
|EK| = sqrt((4 - 3)^2 + (4 - 10)^2) = sqrt(1^2 + (-6)^2) = sqrt(37)
|DT| = sqrt((-4 - 1)^2 + (-2 - (-1))^2) = sqrt((-5)^2 + (-1)^2) = sqrt(26)
|KS| = sqrt((-1 - 4)^2 + (3 - 4)^2) = sqrt((-5)^2 + (-1)^2) = sqrt(26)^2
Since the corresponding sides of the two triangles are equal. the two triangles are congruent by SSS.
