Let's verify each case to determine the solution to the problem
we know that
The equation of the vertical parabola is of the form
where
is the vertex of the parabola
<u>case A)</u>
In the case A) the vertex is the point
Therefore
the case A) is not the solution of the problem
<u>case B)</u>
In the case B) the vertex is the point
Therefore
the case B) is not the solution of the problem
<u>case C)</u>
In the case C) the vertex is the point
Therefore
the case C) is not the solution of the problem
<u>case D)</u>
In the case D) the vertex is the point
Therefore
the case D) is the solution of the problem
<u>the answer is the option D</u>
Answer:
a. x = 24
b. x = 40
Step-by-step explanation:
a.
You are given a right triangle, so use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + 18^2 = 30^2
x^2 + 324 = 900
x^2 = 576
x = 24
b.
The sum of the measures of all angles is 360 degrees.
x + 2x + 2x + 20 + 3x + 20 = 360
8x + 40 = 360
8x = 320
x = 40
<span>w = 0.4444444444x
becase you gotta divide each side by 9 so if you simplify it its
</span><span>w = 0.4444444444x</span>
Answer:
(-2, 3).
Step-by-step explanation:
x + 3y = 7
2x + 4y = 8
1 . x = 7 - 3y.
2. 2(7 - 3y) + 4y = 8
3. 14 - 6y + 4y = 8
-2y = -6
y = 3
4. Substitute y in the second equation:
2x + 4(3) = 8
2x = -14
x = -2..
