Step-by-step explanation:

you would flip the 9^-2 which would be 1/9^2

which would simplify to 1/81

Answer:

StartFraction 1 Over 81 EndFraction

Step-by-step explanation:

To get the equivalent expression for 9^-2, we will use the law of indices to solve it.

First we will remove the minus sign at the power, the removal of this sign will convert the value into a fraction. For example, one of the law of indices states;

a^-n = 1/a^n

Applying this law to the value given;

9^-2 = 1/9²

Next is to find the square of 9

9² = 9×9 = 81

Therefore our final answer will give;

9^-2 = 1/9²

= 1/81

The answer is B. StartFraction 1 Over 81 EndFraction

Answer: y = -1/2

Step-by-step explanation:

Subtract both sides by 7/8

y = 3/8 - 7/8

Then combine like terms

y = -4/8

Then simplify

y = -1/2

Question 1
vivado [14]

Answer:

For Lin's answer

Step-by-step explanation:

When you have a triangle, you can flip it along a side and join that side with the original triangle, so in this case the triangle has been flipped along the longest side and that longest side is now common in both triangles. Now since these are the same triangle the area remains the same.

Now the two triangles form a quadrilateral, which we can prove is a parallelogram by finding out that the opposite sides of the parallelogram are equal since the two triangles are the same(congruent), and they are also parallel as the alternate interior angles of quadrilateral are the same. So the quadrilaral is a paralllelogram, therefore the area of a parallelogram is bh which id 7 * 4 = 7*2=28 sq units.

Since we already established that the triangles in the parallelogram are the same, therefore their areas are also the same, and that the area of the parallelogram is 28 sq units, we can say that A(Q)+A(Q)=28 sq units, therefore 2A(Q)=28 sq units, therefore A(Q)=14 sq units, where A(Q), is the area of triangle Q.

O a Olivia went to a dance party. She paid $12 as an entry fee. Once inside the dance party, she paid $2 per snack. She started
Oduvanchick [21]

Answer: 2x + 12 = 30

12 is the initial fee, then x is the unknown variable. Since each snack costs 2 dollars, and we don't know how many she had, we can use the equation:

2x +                   12 =               30

|                           |                     |

snack          initial                total

fee                fee                 $ spent
