The answer could be 48/5 or 9 and 3/5 or 9.6 These all mean the same exact thing. You get the answer by multiplying 12/1 and 4/5 to get 48/5.
Answer:
- x = 0 or 1
- x = ±i/4
- x = -5 (twice)
Step-by-step explanation:
Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.
1. x^2 -x = 0
x(x -1) = 0 . . . . . x = 0 or 1
__
2. 16x^2 +1 = 0
This is the "difference of squares" ...
(4x)^2 - (i)^2 = 0
(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)
__
3. x^2 +10x +25 = 0
(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2
Answer:
[see below]
Step-by-step explanation:
Using the Pythagorean Theorem:

Hope this helps.
Answer:
y =
x + 7
Step-by-step explanation:
Given
x = 3t ( divide both sides by 3 )
x = t
Substitute this value into y = 2t + 7
y = 2 ×
x + 7 =
x + 7
His meal has a total of 551 calories.
300+150 = 450
450 + 101 = 551
