metres.
What is the volume of the large room?
Answer:
The remaining solution to the equation is x = 1
Step-by-step explanation:
2x^2 + x - 1 = 2
First set the equation to zero by subtracting 2 from each side:
2x^2 + x - 1 - 2 = 2 - 2
2x^2 + x - 3 = 0
Factor the left side of the equation:
2x^2 + x - 3 = 0
(2x + 3)(x - 1) = 0
Now set each factor to zero and solve:
2x+ 3 = 0
2x+ 3 - 3 = 0 - 3
2x= -3
2x/2= -3/2
x= -3/2 (The given expression)
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1
Since we already knew x = -3/2, the missing solution is x = 1.
Answer:
f(t)=t²-12t+11
Step-by-step explanation:
1) Having an attentive reading, we can see from the picture two coordinate points (1,0) and (11,0).
These points, has coordinates for x and y. Since those y-coordinates are zero, we have x-intercepts. Or the zeros of a function, in a quadratic function. Those intercepts minus x values equals zero. These x-intercepts we'll rename it as t, for time.
2) Plugging it in and writing it as groups:
f(t) = returns in feet
t= for time
f(t) =(t-1)(t-11)
Distributing the factors multiplying (t-1) times (t-11), goes:
f(t) =t²-12t+11
x^2 -12x +11
We have the x intercepts so we can create the equation (x-1)(x-11). Multiply it and you get your answer
y=5-6x
Answer:
1 is the slope
Step-by-step explanation:
For perpendicular lines, you need to find the negative recipricol which would be 1 for -1
Answer:
y=x+4
Step-by-step explanation:
just flipped the sign of the slope and the line will go the other way
this question is worded a little weird because the y is not what represents slope in the formula so. Assuming that, the answer to the first part should be correct
