A number is :
_________________________________
Three quarters of it means :
_________________________________
Decrease by 20 means :
_________________________________
Equals to 82 means :
_________________________________
What is that number ?
x asked so we must solve the above equation for x.
Let's do it....
Plus sides 20
Multiply sides by 4
Divided sides by 3
Simplify
So that number is 136 .

Answer:
a or c
Step-by-step explanation:
Answer:
y = 9
Step-by-step explanation:
We notice that both points have a y-coordinate of 9. Since they are the same, the equation must be y = 9 because the function can't "dip" or "rise", otherwise it would be a piecewise function and not a linear function. The equation y = 9 basically means that no matter what x is, y will always be 9.
Answer:
Step-by-step explanation:
The coefficients of the quadratic x^2 + 7x + 3 are a = 1, b = 7 and c = 3.
The discriminant is b^2 - 4ac, or 49 - 4(1)(3), or 49-12, or 37.
Because the discriminant is positive, we know that this quadratic equation has two real, different solutions.
-7 ± √37
x = --------------- => x = (-7 + √37)/2 and x = (-7 - √37)/2
2
In words: This quadratic equation has two real, unequal solutions involving the radicand 37.
