If you're trying to solve for x, you need to use the quadratic formula.
Plug in the numbers from the standard form of a quadratic equation
(which is
)
From here, this solves down to
Take the square root of 196, which is 14
Now, you can solve for both the + and - variations on the equation.
The solutions to your equation are 1.5 and 5/8 (probably)
Answer:
4/5
Step-by-step explanation:
We can find the slope when given two points by using
m= (y2-y1)/(x2-x1)
= (8-0)/(10-0)
=8/10
= 4/5
The area of the triangle with the coordinate of the vertice will be 6 square units.
<h3>What is the triangle?</h3>
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
Triangle RST, with vertices R(5,-9), S(9,-5), and T(7,-4), is drawn on the coordinate grid below.
Then the area of the triangle will be
Area = 1/2 [(x₁y₂ + x₂y₃ + x₃y₁) - (y₁x₂ + y₂x₃ + y₃x₁)]
Area = 1/2 [{5 x -5 + 9 x -4 + 7 x -9} - {-9 x 9 + -5 x 7 + -4 x 5}]
Area = 1/2 [{-124} - {-136}]
Area = 1/2 [ -124 + 136]
Area = 1/2 x 12
Area = 6 square units

Answer:
<h3>30%</h3><h3>
Step-by-step explanation:</h3>
No. of boys = 50 - 35
= 15
Percentage of boys
= No. of boys / Total Students * 100
=> 15/50 * 100
=> 30%
So, the percentage of boys in the school is 30%
