Answer:
D - x = 19 x = -17
Step-by-step explanation:
Factor the equation to make the problem easier - you should have this:
(x - 18) (x + 18) = 1
Set each binomial to 1:
x - 18 = 1
x + 18 = 1
This should give you x = 19 and x = -17
Answer: The side highlighted is 6.3 units long
Step-by-step explanation:
You can use Pythagorean therum to solve this problem
a² + b² = c²
We already know the length of two of the sides, a and b. So we will replace those variables with the given values
2² + 6² = c²
And now we solve
2² + 6² = c²
4 + 36 = c²
c² = 40
<em>√40 = 6.3</em>
(-1,3)(0,0)
slope(m) = (0 - 3) / (0 - (-1) = -3/1 = - 3
y = mx + b
slope(m) = -3
y int (b) = 0
ur equation is : y = -3x
function notation is : f(x) = -3x <==
Answer:
2n+5 =3
n=-1
The number is -1
Step-by-step explanation:
Let n be the number
Twice the number
2n
Plus 5
2n+5
is means equals
2n+5 =3
Now we want to solve
Subtract 5 from each side
2n+5-5 = 3-5
2n = -2
Divide each side by 2
2n/2 = -2/2
n = -1
Slope: -3
y intercept: 0,5
