What would x+2y=-2 in slope intercept form?

3(2v-1)=6v-4 can someone pls help me with this

ZanzabumX [31]

Answer:

Step-by-step explanation:

dy/dx= -(2x+3y+1)/(3x-2y+1)

Let x= X+p. and y = Y+q. then dy/dx = dy/dX.

dy/dX= -(2X+2p+3Y+3q+1)/(3X+3p-2Y-2q+1) =

dy/dX = -{2X+3Y+(2p+3q+1)}/{3X-2Y+(3p-2q+1)}

Now 2p+3q+1=0……………..(1)

3p-2q +1=0…………………………(2)

p/(3+2)=q/(3–2)=1/(-4–9)

NEED ANSWER ASPA.... PLS HURRY

We have that
$y=- x^{2} +36$

we know that
Is the equation of a vertical parabola open down
so
the vertex is a maximum

step 1
convert the equation of the parabola in the vertex form
$y=- x^{2} +36 \\ y-36=- x^{2}$

the vertex (h,k) is the point (0,36)

Part a) The point on the graph where the height of the tunnel is a maximum is (0,36)

Part b) The points on the graph where the height of the tunnel is zero feet is when y=0
so
for y=0
$- x^{2} +36=0 \\ x^{2} =36 \\ x= (+/-) 6$

the points are (-6,0) and (6,0)

see the attached figure

Answer:

$\approx 26.16\:\mathrm{m}$

Step-by-step explanation:

Let $h$ be the height of the tree. In reference to the tree and bird, a right triangle is formed. We can write the following trig function for that right triangle:

$\tan28^{\circ}=\frac{h}{15},\\h=15\tan28^{\circ},\\h\approx 7.98\:\mathrm{m}$ .

Now we can use this to find the hypotenuse of this triangle (the distance between the cat and the bird):

Let the distance between the cat and bird be $k$ . Then,

$7.98^2+15^2=k^2,\\k\approx 16.99\:\mathrm{m}$ . This is one side of the triangle that is formed by the cat, bird, and mouse.

The right triangle formed by the tree, cat, and mouse shares the height $h$ with the other right triangle, as we found earlier. Let $l$ represent the hypotenuse of this triangle or the distance between the cat and mouse. We then have the following trig function:

$\sin 40^{\circ}=\frac{7.98}{l},\\l=\frac{7.98}{\sin40^{\circ}}\approx 12.41\:\mathrm{m}$ . This is another side of the triangle that is formed by the cat, bird, and mouse.

The triangle that is formed by the cat, bird, and mouse has shares an angle of $125^{\circ}$ with the base of the auxiliary pyramid. The other angles, however, are not shared.

Since we have two sides and the angle between these two sides, we can use the Law of Cosines to find the other side (the distance between the mouse and bird). The Law of Cosines is given by:

$m^2=k^2+l^2-2kl\cos M$ , where $m$ is the distance between the bird and the mouse and the other variables are defined above.

Plugging in values, we get:

$m^2=16.99^2+12.41^2-2\cdot16.99\cdot12.41\cdot\cos 125^{\circ}$

Solving, we get:

$m\approx \fbox{$26.16\:\mathrm{m}$}$ .

Please help me for 3 and 4

Linear functions always go up by the same value. You can subtract 2 y values and divide it by the corresponding x values (subtracted the same way) and you will get the same number. Here is an example from ur chart. 3). (9-7)/(3-2) = 2. Now try it for another two values. You get 2. That means it is linear. The equation for it would be y=2x+3
Now do the next one good luck!
