A. Because 4 * 5 = 20, that makes it blank/20 then 1 * 4 is 4 and 1 * 5 is 5 and add 4 and 5, 9. that makes it 9/20

Well one week she'd have 23.50$. So per week you multiply that number by the number of weeks.

√(5-2x) - √(2-x) = 1
Eva8 [605]
Square both sides. (5-2x) - (2-x) = 1^2. 5 - 2x - 2 + x = 1. Simplify to get 3 - x = 1. X=2

Given that y varies directly with x in the table below, what is the value of y if the value of x is 7?
Black_prince [1.1K]
Write out the governing equation:

y = kx.

Take any point from the given table.  You haven't shared the table, so I will invent a point:  (2, 9).

Then find k:  k = 9/2        Then the equation becomes   y = (9/2)x.

Now let x = 7 and find y:                           y = (9/2)(7) = 63/2     

Answer:         y = 63/2

Can someone please help me with this math question .
Alona [7]

No, Yes, No, Yes

using the laws of exponents

(1)

(4^{3})³ = 4^{9}

4³ × 4³ = 4^{6}

4^{9} ≠ 4^{6} → No

(2)

(3^{4})^4 = 3^{16}

3^{8} × 3^{8} = 3^{16} → Yes

(3)

18^{8} = (6 × 3 )^8 = 6^{8} × 3^{8} ≠ 6^{4} × 3^{4} → No

(4)

20^{3} = (4 × 5 )³ = 4³ × 5³ → Yes
