Answer:
x = (h-12y-2)/4
Step-by-step explanation:
Here, we want to make x the subject of the formula
We have this as:
h = 4x + 12y + 2
4x = h-12y-2
x = (h-12y-2)/4
Answer:
The slope of the line is -3. in the y-intercept form (y=mx + b) m is the slope.
Just remeber that! :)
Step-by-step explanation:
Answer: x=7
/2
Step-by-step explanation:
1 Simplify both sides of the equation.
−1=6+−2x
−1=−2x+6
2 Flip the equation.
−2x+6=−1
3 Subtract 6 from both sides.
−2x+6−6=−1−6
−2x=−7
4 Divide both sides by -2.
−2x
/−2 -7
/-2
I think I did it correctly, I don´t know how you learned it, so I am truly sorry if I am incorrect.
Area = length x width
Area = 1.25 x 3.4 = 4.25 square meters
<span>The function f is defined by f(x)=x^2+3x-10 If f(x+5)=x^2+kx+30, k= Find the smallest zero of f(x+5), x=
By definition, the zero of a polynomial function is a number a such that f(a)=0. For quadratic equation, the zeros can be found on equalizing f to 0. First, f(x+5)=(x+5)²+3(x+5)-10=x²+10x+25+3x+15-10=x²+13x+30, and it is told that If f(x+5)=x^2+kx+30 = x²+13x+30, it implies k=13, so let’s find the zeros. x²+13x+30=0 is to solve: D= 13²-4x1x30=169-120=49, sqrt49=7, so x=-13-7 / 2=-20/2 = -10, and x= -13+7/ 2 = -6 /2= -3. Obviously, we know that -10< -3, so the smallest zero is -10.
