Answer: x=-1
Step by step:
2|x+6|+9=19
Subtract 9 from both sides.
2|x+6|=10
Divide both sides by 2
|x+6|=5
Use the definition of absolute value.
x+6=5
Subtract 6 on both sides
x=-1
Hope this helped! :)
Step-by-step explanation:
y = .10d + .25q
y is the total amount, if you have d dimes and q quarters
Answer:
Step-by-step explanation:
he spent 75% of his savings to buy a camera that costs 325....
so 75% of his original savings is 325
let x represent his original savings...." of " means multiply.." is " means equals
75%(x) = 325....turn ur percent into a decimal
0.75x = 325.....divide both sides by 0.75
x = 325 / 0.75
x = 433.33 <=== ur answer
check...
0.75(433.33) = 325
324.99 (rounds to 325) = 325
Welcome to the concept of the maths.
Here, we can see, that Linear equation always have highest power or degree of its variable as '1' ,
thus here, y = 3/x has degree as -1 and y = x^2 +5 has degree 2 ,
hence,
The equations that are NOT linear are
2.) y = 3/x and 5.) y = x^2 + 5
