Find the coordinates of the points of intersection of the graphs with coordinate axes: y=− 1/4 x+2

bearhunter [10]

Answer:

Step-by-step explanation:

Here, you can use a simple formula.

To find the point of intersection you just put x=0 or y=0.

Because, if a graph intersects x-axis, then at this point y=0

Similarly, if a graph intersects y-axis, then at this point x=0

So, for our given line.

y=-1/4 x +2

when , x=0 , y=-1/4 (0)+2=2

So, the graph intersects y-axis at y=2

when , y=0 ,

then 0=-1/4 x+2

or, 1/4 x=2

or, x=8 [multiplying by 4]

So, the graph intersects x-axis at x=8

Subtract: 2x2 - 4x - 3 from x2 - 5x - 8.

VladimirAG [237]

X^2 - 5x - 8 - <span>2x^2 + 4x + 3
= -x^2 - x - 5

hope that helps</span>

For this case we have that by definition, the point-slope equation of a line is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

m: It's the slope

$(x_ {0}, y_ {0}):$ It is a point through which the line passes

According to the statement data we have:

$m = 5\\(x_ {0}, y_ {0}): (- 8,1)$

Substituting we have:

$y-1 = 5 (x - (- 8))$

By law of signs of multiplication we have to:

$- * - = +\\y-1 = 5 (x + 8)$

Answer:

The requested equation is: $y-1 = 5 (x + 8)$

Pls solve question 4b. Verrry urgent . Ok tyy

kodGreya [7K]

Answer:

$y = 3\left(x-\dfrac{3}{2}\right)^2+\dfrac{41}{4}$

Step-by-step explanation:

Given equation:

$y = 3x^2 - 9x + 17$

Factor out 3 from the first 2 terms:

$y = 3(x^2 - 3x) + 17$

Divide the coefficient of x by 2 and square it: (-3 ÷ 2)² = 9/4

Add this inside the parentheses and subtract the distributed value of it outside the parentheses:

$y = 3\left(x^2 - 3x+\dfrac{9}{4}\right) + 17-\dfrac{27}{4}$

Factor the parentheses and combine the constants:

$y = 3\left(x-\dfrac{3}{2}\right)^2+\dfrac{41}{4}$
