Answer:
→ The table is:
→ x → -1 → 0 → 1
→ y → -3 → 0 → 3
The graph of the line is figure d
Step-by-step explanation:
∵ y = 3x
∵ x = -1, 0, 1
→ Substitute the values of x in the equation to find the values of y
∴ y = 3(-1) = -3
∴ y = 3(0) = 0
∴ y = 3(1) = 3
→ The table is:
→ x → -1 → 0 → 1
→ y → -3 → 0 → 3
∵ The form of the linear equation is y = m x + b, where
∵ y = 3x
→ Compare the equation with the form
∴ m = 3
∴ b = 0
→ That means the slope is positive, then the direction of the line must
be from left tp right and passes through the origin
∴ The graph of the line is figure d
Answer:
90 degrees, 60 degrees and 30 degrees
Step-by-step explanation:
90/3 = 30
30 x 2 = 60
Answer:
C. x = 40
Step-by-step explanation:
1. Get the supplementary angle of ∠9: 180 - m∠9 = 180 - (4x-10)
2. The inside angles of that triangle add up to 180: 30 + 3x + 180 - (4x-10) = 180
3. Solve for x:
30 + 3x + 180 - (4x-10) = 180
30 + 3x + 180 - 4x + 10 = 180 Distribute negative to parenthesis
220 - x = 180 Combine like terms
-x = -40 Subtract 220 on both sides
x = 40 Divide both sides by -1
Answer is (1,3)
I took algebra 2 years ago so hope it helps
