Then ,according to the Pythagorean theorem:

$b = \sqrt{a^2 + c^2}$

$= \sqrt{6^2 + 7^2}$

$= \sqrt{36 + 49}$

$= \sqrt{85}$

Is this right ? Im honestly confused

Answer:

In step by step

Step-by-step explanation:

For #1, everything is perfect.

For #2, you wrote your functions out incorrectly, but your x input and y output are correct

#3 is a little messed up.

Your function is f(x)=-3x+1. Your given x's are -3, -1, 0, 1, 2, and 3. Plug all of these in.

1. f(-3)=-3(-3)+1

f(-3)=9+1
f(-3)=1

2. f(-1)=-3(-1)+1

f(-1)=3+1
f(-1)=4

3. f(0)=-3(0)+1

f(0)=0+1
f(0)=1

4. f(1)=-3(1)+1

f(1)=-3+1
f(1)=-3

5. f(2)=-3(2)+1

f(2)=-6+1
f(2)=-5

Solve for a . 326 = 5( 8a + 8 )

Stels [109]

Answer:

Answer is below

Step-by-step explanation:

Always remember to simplify both sides of the equation.

$326=5(8a+8)\\326=(5)(8a)+(5)(8)\\(Distribute)\\326=40a+40\\$

Flip the equation

$40a+40=326$

Subtract 40 from both sides.

$40a+40-40=326-40\\40a=286$

Divide both sides by 40.

$40a/40=286/40\\Answer:a=143/20 \\(decimal 7.15)$
