Hello,

9k - 2 88

⇔ 9k - 2 + 2 ≥ 88 + 2

⇔ 9k ≥ 90

⇔ 9k/9 ≥ 90/9

⇔ k ≥ 10

S = [10 ; + ∞ [

Answer:

k ≥ 10

Step-by-step explanation:

9k - 2 ≥ 88

Step 1 : Add 2 on both sides.

9k - 2 + 2 ≥ 88 + 2

9k + 0 ≥ 90

9k ≥ 90

Step 2 : Divide 9 on both sides.

9k/9 ≥ 90/9

k ≥ 10

Each of the 3 twins sleep in a twin bed. They all need sheets. At a store they have sheets that are 50% off and each sheet is 18

Debora [2.8K]

Each sheet is $9 with the discount. 2 sheets would cost $18 because 9x2 is 18. 6 sheets would cost $54 dollars because 9x6 is 54.

Given M is the midpoint ABA. The coordinate of A are (-4,2) and the cordinates of M are (1,1). Find the coordinate of B. Choose

4vir4ik [10]

Answer:

The coordinate of B is (6,0)

Step-by-step explanation:

Given;

coordinate of A = (-4,2) = (x₁, y₁)

coordinate of M = (1,1)

let coordinate of B = (x₂, y₂)

Mid-point is given by;

$M = \frac{X_1 + X_2}{2} , \frac{Y_1 + Y_2}{2}\\\\M= (1,1)\\\\1,1 =\frac{X_1 + X_2}{2} , \frac{Y_1 + Y_2}{2}\\\\ \frac{X_1 + X_2}{2} = 1 ----equation (1)\\\\\frac{Y_1 + Y_2}{2} = 1 -----equation(2)\\\\Solving \ equation(1)\\\\\frac{-4+ X_2}{2} = 1\\\\-4+ X_2 = 2\\\\X_2 = 2+4\\\\X_2 = 6\\\\Solving \ equation(2)\\\\\frac{Y_1 + Y_2}{2} = 1\\\\\frac{2+ Y_2}{2} = 1\\\\2+Y_2 = 2\\\\Y_2 = 2-2\\\\Y_2 = 0\\\\B = (X_2, \ Y_2)\\\\B = (6, \ 0)$

Therefore, the coordinate of B is (6,0)

Which equation represents seven times a number decreased by 2 is 19? A) 7 + x - 2 = 19 B) 7x + 2 = 19 C) 2x - 7 = 19 D)

Helen [10]

Answer:

7n - 2 = 19

Step-by-step explanation:

7 times a number is 7n.

7 times a number, decreased by 2, is 7n - 2.

7 times a number, decreased by 2, is 19 is represented by 7n - 2 = 19

For the equation, decide if it is always true or never true. 2(x + 3) = 5x + 6 − 3x

SCORPION-xisa [38]

Answer:

always true

Step-by-step explanation:

Given

2(x + 3) = 5x + 6 - 3x ← distribute left side

2x + 6 = 2x + 6

Since both sides are equal then any real value of x is a solution.

Thus the equation is always true
