I think the answer is 0.
Sorry if it is wrong..
Answer:
x = 1
y = -5
Step-by-step explanation:
In this question, we need to find what the values of "x" and "y" are.
To do this, we must solve the equations.
Solve:
6x + 2y = -4
3x + 4y = -17
Lets solve for "y" first:
6x + 2y = -4
-2(3x + 4y = -17) = -6x - 8y = 34
Now subtract the two equations from each other.
6x + 2y = -4
-6x - 8y = 34
-6y = 30
Divide both sides by -6
y = -5
Now, we know that the "y" variable's value is -5.
Lets find the value of "x" by plugging -5 to "y" in one of the equations:
6x + 2(-5) = -4
6x - 10 = -4
Add 10 to both sides.
6x = 6
Divide both sides by 6.
x = 1
The value of "x" is 1.
they are parallel, so they have the same slope. subtract y2 from y1 (7-1) and divide it by x2-x1 (4-1). you get 6/3, which is 2
The value of the "6" in 49.62 is in the<u> tenth</u> place
Given:
The image of a lens crosses the x-axis at –2 and 3.
The point (–1, 2) is also on the parabola.
To find:
The equation that can be used to model the image of the lens.
Solution:
If the graph of polynomial intersect the x-axis at c, then (x-c) is a factor of the polynomial.
It is given that the image of a lens crosses the x-axis at –2 and 3. It means (x+2) and (x-3) are factors of the function.
So, the equation of the parabola is:
...(i)
Where, k is a constant.
It is given that the point (–1, 2) is also on the parabola. It means the equation of the parabola must be satisfy by the point (-1,2).
Putting in (i), we get
Divide both sides by -4.
Putting in (i), we get
Therefore, the required equation of the parabola is .
Note: All options are incorrect.
