Answer:

The first, third and the fifth.

Step-by-step explanation:

First one is equivalent

√(8^2*8^2)

= √64*64

= √64.

8^1/2 * 8^1/2

= 8^1

= √64.

√(16*4)

= √64.

Which statement is true about the line represented on the equation y + 7 = -3 (x - 2/9) ?

Zarrin [17]

ANSWER

The point $(\frac{2}{9},-7)$ lies on the straight line $y+7=-3(x-\frac{2}{9})$

EXPLANATION

The given line is $y+7=-3(x-\frac{2}{9})$ . It can be observed that the given straight line is in the point-slope form.

We can rewrite the equation in the point-slope form to obtain,

$y--7=-3(x-\frac{2}{9})$ .

When we compare this to the general point-slope form, which given by the formula;

$y-y_1=m(x-x_1)$ ,

We can observe that,

$x_1=\frac{2}{9}$ and $y_1=-7$ .

Hence the point, $(x_1,y_1)=(\frac{2}{9},-7)$ lies on $y+7=-3(x-\frac{2}{9})$

PLEASE HELP. I know how to do these but I'm stuck on this one.

Nezavi [6.7K]

Steve ran 11 miles

let the distance Steve ran be x

Then distance Kevin ran is x + 4 ( 4 miles more than Steve )

x + x + 4 = 26 ( the sum of their distance is 26 )

2x + 4 = 26 ( subtract 4 from both sides )

2x = 22 ( divide both sides by 2 )

x = 11

Steve ran 11 mies and Kevin ran 11 + 4 = 15 miles

check 11 + 15 = 26
