the sequence is arithmetic because it's incrementing by a constant ratio of -4
Answer:
A
Step-by-step explanation:
To determine if the ordered pairs lie on the graph, substitute the x- coordinate of the point into the equation and if the value agrees with the y- coordinate of the point then it lies on the graph
A
x = - 2 : y = -2(- 2) + 7 = 4 + 7 = 11 ≠ 3 ← (-2,3) not on graph
B
x = - 1 : y = - 2(- 1) + 7 = 2 + 7 = 9 ← (- 1, 9) lies on graph
C
x = 3 : y = -2(3) + 7 = - 6 + 7 = 1 ← (3, 1) lies on graph
D
x = 4 : y = - 2(4) + 7 = - 8 + 7 = - 1 ← (4, - 1) lies on graph
Step-by-step explanation:
________________________________
Step 1:
Wright the equation
________________________________
Step 2:
Transfer the power of y ie ¹² up to subtract it
________________________________
Step 3:
by subtracting the powers we get 0
________________________________
Step 4:
so the results comes 1 because anything ⁰=1

Answer:
x =4
Step-by-step explanation:
2/3(x-7)= -2
Multiply each side by 3/2 to clear the fractions
3/2 * 2/3(x-7)= -2 *3/2
x-7 = -3
Add 7 to each side
x-7+7 = -3+7
x =4
2(2y^4 + 7y^3 - 4y^2 -20)
