Answer:
d = -1/3, 0
Step-by-step explanation:
Subtract the constant on the left, take the square root, and solve from there.
(6d +1)^2 + 12 = 13 . . . . given
(6d +1)^2 = 1 . . . . . . . . . .subtract 12
6d +1 = ±√1 . . . . . . . . . . take the square root
6d = -1 ±1 . . . . . . . . . . . .subtract 1
d = (-1 ±1)/6 . . . . . . . . . . divide by 6
d = -1/3, 0
_____
Using a graphing calculator, it is often convenient to write the function so the solutions are at x-intercepts. Here, we can do that by subtracting 13 from both sides:
f(x) = (6x+1)^ +12 -13
We want to solve this for f(x)=0. The solutions are -1/3 and 0, as above.
B, no
Subtract 2c from both sides to get
-c=-4
Multiply by -1 to get
c=4
Answer:
A because if you solve for x then it becomes x<5. So obviously x has to be less than 5, and since you can not have a decimal of a tablet, the answer is 4.
Step-by-step explanation:
Y=-6x+8 is a linear equation because the x is not an exponent. It also is a straight line, not a curve (parabola) or exponential growth rate. I hope I helped! ^u^
