<h3>
<u>Given</u> - </h3>
➙ a quadratic equation in which Harry lagged due to an error made by him, 2x² - x - 6= 0
<h3>
<u>To solve</u> - </h3>
➙ the given quadratic equation.
<h3>
<u>Concept applied</u> - </h3>
➙ We will apply the quadratic formula as given in the question. So, let's study about quadratic equation first because we are supposed to apply the formula in equation.
What is quadratic equation?
➙ A quadratic equation in the variable x is an equation of the form ax² + bx + c = 0, where a, b, c are real numbers, a ≠ 0.
Now, what is quadratic formula?
➙The roots of a quadratic equation ax + bx + c = 0 are given by 
provided b - 4ac ≥ 0.
<h3>
<u>Solution</u> - </h3>
here as per the given quadratic equation,
a = 2, b = -1 and c = -6
putting in the formula,
Solving one by one,

the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
Kimtoya is riding according to the equation y = 12.5x, which is in slope-intercept form where the slope is 12.5, so her rate is 12.5.
now, Sidney's rate... hmmm we don't know, but we have her table ahaa!, well, let's use that to get the slope or rate for Sydney let's pick two points from it hmmm say (2 , 25) and hmmm (5 , 62.5)
holy molly!, whaddaya know, they're both riding at the same rate, 12.5 km/hr
Answer:
66 cm³
Step-by-step explanation:
Volume of the oblique prism = Area of the base× height
V = Area of the triangular base × height
V = (bh/2)H.................. Equation 1
Where V = Volume of the prism, b = bas of the triangle, h = height of the triangle, H = height of the prism.
From the diagram,
b = 3 cm, h = 4 cm, H = 11 cm.
Substitute these values into equation 1
V = [(3×4)/2]×11
V = 6×11
V = 66 cm³
Hence the volume of the oblique prism is 66 cm³
Parallel lines have the same slope.The equation of a line is y=mx+b
where m is the slope
so look at lines where m=2
d is the correct answer
because y=2x-10 so m=2
Answer:
(- 2, - 3) and (1, 0)
Step-by-step explanation:
The solution to a system of equations given graphically are at the points of intersection of the 2 graphs.
The solutions are therefore (- 2, - 3 ) and (1, 0 )
