What is equation?A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter. Frequently, the logo and the particular software are identical. like in 2x - 4 = 2, for example.
It is hard to tell which equation may be the equation of the parabola without further details on the parabola's orientation and location.
The equations in options A and B are parabolas with upward or downward openings and a vertex at the origin. The equation of a parabola with its vertex at the origin and an opening to the right or left is in Option C. The equation of a parabola with an upwards or downwards opening and its vertex at the point is in Option D. (0,0).
The position and direction of the relevant parabola will determine the appropriate response.

Find the value of x.
Hanz’s class had a goal to collect 250 cans of food for the school food drive. They collected 290 cans. What percent of their goal did they achieve?
Given:
Goal = 250 cans
Number of collected cans = 290
To find:
The percent of their goal they achieved.
Solution:
The percent of their goal they achieved is:
[tex]\text{Required percent}=\dfrac{\text{Number of collected cans}}{\text{Goal}}\times 100[/tex]
[tex]\text{Required percent}=\dfrac{290}{250}\times 100[/tex]
[tex]\text{Required percent}=\dfrac{29}{25}\times 100[/tex]
[tex]\text{Required percent}=29\times 4[/tex]
[tex]\text{Required percent}=116[/tex]
Therefore, they achieved 116% of their goal.

Solve the equation x^2 - 4x + 6 = 9 by completing the square.
Hello!
x² - 4x + 6 = 9 <=>
<=> x² - 4x + 6 - 9 = 0 <=>
<=> x² - 4x - 3 = 0 <=>
<=> x = -(-4)±√(-4)²-4×1×(-3)/2×1 <=>
<=> x = 4±√16+12/2 <=>

Answer:
140
Step-by-step explanation:
Angles 1, 2 and 3 are in a straight line,
Straight line has 180 degrees,
∠1 = ∠3 = 20
∠1 + ∠2 + ∠3 = 180
20 + ∠2 + 20 = 180
∠2 + 40 = 180
∠2 = 180 - 40
∠2 = 140

The legs of a right triangle have the following measurements: 5 and 10 inches. What is the length of the hypotenuse??
show work.
Answer:
[tex]5\sqrt{5}[/tex]
Step-by-step explanation:
1. [tex]5^2 +10 ^2 = c^2[/tex]
2. [tex]c^2 = 125[/tex]
3. [tex]c = 5\sqrt{5}[/tex]
Answer:
approximately 11.18 inches or [tex]5\sqrt{5[/tex] inches
Step-by-step explanation:
We have to use Pythagorean Theorem for this problem. a^2 + b^2 = c^2, where c is the hypotenuse and a/b are legs of the right triangle.
5^2 + 10^2 = c^2, 25 + 100 = c^2, 125 = c^2, sqrt125 = c
sqrt125 can be simplified to 5sqrt5 (25 * 5 = 125, sqrt25 = 5)
The hypotenuse is approximately 11.18 inches or [tex]5\sqrt{5[/tex] inches.
