What is the equation of a line that passes through the point (-4,4) and has a slope of -2

Mathematics
1 answer:
Lyrx [107]3 years ago
6 0

Equation is 2x + y = -4

Step-by-step explanation:

  • Step 1: Use the point slope form to get the equation. The point is (x1, y1) = (-4, 4) and slope, m = -2

Point slope Form ⇒ y - y1 = m(x - x1)

⇒ y - 4 = -2(x - -4)

⇒ y - 4 = -2(x + 4)

⇒ y - 4 = -2x - 8

⇒ 2x + y = -4 is the equation

Which Mean Absolute Deviation represents more consistency? 15.2 or 10.9
Firdavs [7]

Answer:

10.9

Step-by-step Explanation:

The Mean Absolute Deviation of a given data set tells us how far apart, on average, each data value is to the mean of the data set.

The smaller the Mean Absolute Deviation of a given data set is, the closer each data value is to the mean. This also implies less variability of the data set.

Invariably, the smaller the M.A.D, which connotes less variability, the more consistent the data set is.

Therefore, a M.A.D of 10.9 represents more consistency than a M.A.D of 15.2

Please help!! <br><br>is it 16?​
sweet-ann [11.9K]

Answer:

area of trapezium: -

formula...

½(sum of parallel sides)×height=area

=>240=½(12+x)×12

=>240=(12+x)×6

=>240=60+6x

=>6x=240-60

=>6x=180

=>x=180/6

=>x=30cm

therefore, the value of x is 30 cm.

What is the relationship between the discriminant of a quadratic and its graph?
faltersainse [42]

Answer:

In a quadratic equation of the shape:

y = a*x^2 + b*x + c

we hate that the discriminant is equal to:

D =  b^2 - 4*a*c

This thing appears in the Bhaskara's formula for the roots of the quadratic equation:

x = \frac{-b +-\sqrt{b^2 - 4ac} }{2a}

You can see that the determinant is inside a square root, this means that if D is smaller than zero we will have imaginary roots (the graph never touches the x-axis)

If D = 0, the square root term dissapear, and this implies that both roots of the equation are the same, this means that the graph touches the x axis in only one point, wich coincides with the minimum/maximum of the graph)

If D > 0 we have two different roots, so the graph touches the x-axis in two different points.
