Answer:
x = ±4
Step-by-step explanation:
3x^2 =48
Divide by 3
3x^2/3 = 48/3
x^2 = 16
Take the square root of each side
sqrt(x^2) = ±sqrt(16)
x = ±4
Answer:
Step-by-step explanation:
Perform the indicated multiplication (squaring):
-3(y^2 + 4y + 4) - 5 + 6y
Continuing with the multiplication:
-3y^2 - 12y - 12 - 5 + 6y
Combiing the y terms in descending order by powers of y:
-3y^2 - 6y - 17
(34 + 6 ) * 3
there would be no equal sign since it is an expression
Y-2=-3/5x -6/5
(5)(y-2)=(-3/5x-6/5)(5)
5y-10=-3x-6
5y+2x=4
The standard form of a line is an easy way to solve for the properties of a line, such as slope and the intercepts. Take a line with the equation in standard form,
Ax + By = C
The slope here is given by y = -A/B.
The x-intercept here is given by (C/A, 0).
The y-intercept here is given by (0, C/B).
For this problem, the equation is 2x + 4y = 12. Thus,
slope = -2/4 = -1/2
y-intercept = (0, 12/4) = (0, 3)
