Answer:
Step-by-step explanation:
3(1) + 4(3) + 9 = 0
3 + 12 + 9 = 0
24 ≈ 0
Answer: the number is -3
Step-by-step explanation:
Four times a number is three times the difference of that number and one
Let the number be x. Four times the number means 4×x = 4x
three times the difference of that number and one. This means
Difference of the number and one is (x-1). Three times the difference of the number and one would be 3(x-)
Four times a number = three times the difference of that number and one. Therefore,
4x = 3(x-1)
Opening the bracket
4x = 3x -3
4x-3x = -3
x =-3
Check
4×-3 =3(-3-1)
-12 = -3×4
-12 = -12
So the number is -3
The function 
sits with its starting point at the origin. The function 
is translated h units to the left or right and k units up or down. Since our radicand, the value under the square root sign, is x+7, putting that into our standard form it would be x-(-7) because minus a negative is a positive. So we move the parent graph to the left (-7 moves to the left) 7 units. There is no number k so our function is not moving up or down. Only to the left 7.
Answer:
two real solution
Step-by-step explanation:
x^2 + 10x − 25 = 0
we can solve this by finding out the value of x
lets assume the equation is a\times x^{2}+b\times x+c=0
x=-b\pm \sqrt{(b^{2}-4ac)}\div 2a
x=-10\pm\sqrt{100+4*25}\div2
x=-5\pm5\sqrt2
then we get both real value of x
so two real solution
Answer:
k = 24
y = 24x
Step-by-step explanation:
72/3 = 24
y = 24x
72 = 24(3)
72 = 72
Hope this helps!
