<span>2(x - 5) + 7 = x + 8
Use distributed property
2x - 10 + 7 = x + 8
Add 7 to -10
2x - 3 = x + 8
Subtract x from both sides
x - 3 = 8
Add 3 to both sides
Final Answer: x=11</span>
The pythagorean theorem states that a^2+b^2=c^2.
3^2 is 9.
9+9=18
The square root of 18 is approximately 4.24.
a.
b.
c.4.24
Answer:
A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.Step-by-step
First the question is sayin that x will be substituted for -10
so for every x put -10
8(-10)=6(-10)-20
then you multiply to get the next expression
so you know that 6 times -10 =-60 and you know that 8 times -10=-80 so now you have
-80=-60-20
now you just solve so you would just subtract -60-20 which would equal -80
so your answer is -80=-80 which is true
