Answer:

Yes

Step-by-step explanation:

To determine if (1, 2 ) is a solution of the inequality, substitute the coordinates into the inequality and if satisfied then they are a solution, that is

(6 × 1) - 2 = 6 - 2 = 4 > 3

Since 4 > 3 then (1, 2 ) is a solution

Lapatulllka [165]

Step-by-step explanation:

At first you need to take its lateral surface area by using the perimeter of base of the triangle and the height of prism.

Then after calculating it you need to find out its total surface area which is asked in the question and that is calculated by adding the area of both triangles of the prism in the lateral surface area.

Then that's your answer.

92 - 16b = 12 help please

Reptile [31]

Answer:

b = -6.5

Step-by-step explanation:

92 - 16b = 12

now you want to get the number(s) and variables on different sides

92 - 16b - 92 = -16b

12 + 92 = 104

-16b = 104

now divide each side by -16

-16b / -16 = b

104 / -16 = -6.5

b = -6.5

Sav [38]

Answer:

1. $\frac{7^8}{7^6}=49$

2. 7

3. 18

Step-by-step explanation:

Question 1:

Given:

The expression to simplify is $\frac{7^8}{7^6}$ .

We use the property of exponent $\frac{a^m}{a^n}=a^{m-n}$

Therefore, $\frac{7^8}{7^6}=7^{8-6}=7^2=7\times 7 = 49$

Question 2:

Given:

The expression to simplify is $7(\frac{1}{2}+\frac{1}{2})$ .

We add the fractions first inside the parenthesis.

So, $\frac{1}{2}+\frac{1}{2}=\frac{1+1}{2}=\frac{2}{2}=1$

Now, $7(1)=7$

Question 3:

The first five prime numbers are 1, 2, 3, 5, and 7.

Therefore, the sum of these five numbers is given as:

$1+2+3+5+7=18$
