Graph the linear equation. Find three points that solve the equation, then plot on the graph. -3x+2y=2

aleksandrvk [35]

First you need to put the equation into slope form which is y = mx + b

-3x + 2y = 2

2y = 3x + 2

y = 1.5x + 1

In this equation the y-intercept is 1 and the slope is 1.5 or 3/2.

To graph the line you can start at the y-intercept then move up 3 and to the right 2 or down 3 and to the left 2.

Three points are (2, 4) , (-2 ,-2), (4, 7).

Hope this helps! Mark as Brainliest please! :)))

Answer:

(x-8)^2+(y-16)^2 = 4

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2+(y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-8)^2+(y-16)^2 = 2^2

(x-8)^2+(y-16)^2 = 4

Segment CD has endpoints (-4, 3) and (8, -1). Find the coordinates of the point that divides the line segment directed from C to

Diano4ka-milaya [45]

Answer:

$A(0.8,\ 1.4)\ \text{or }\ A\left(\dfrac{4}{5},\dfrac{7}{5}\right)$

Step-by-step explanation:

If point $A(x,y)$ divides the segment with endpoints $C(x_1,y_1)$ and $D(x_2,y_2)$ in the ratio $m:n,$

then

$x=\dfrac{nx_1+mx_2}{m+n}\\ \\y=\dfrac{ny_1+my_2}{m+n}$

In your case,

$C(-4,3)\\ \\D(8,-1)\\ \\m:n=2:3$

then

$x=\dfrac{3\cdot (-4)+2\cdot 8}{2+3}=\dfrac{-12+16}{5}=\dfrac{4}{5}=0.8\\ \\y=\dfrac{3\cdot 3+2\cdot (-1)}{2+3}=\dfrac{9-2}{5}=\dfrac{7}{5}=1.4$

Thus,

$A(0.8,\ 1.4)\ \text{or }\ A\left(\dfrac{4}{5},\dfrac{7}{5}\right)$

ASAP HELP HIGH POINTS <br> find the value of x.

Westkost [7]

Answer:

x ≈ 4.2 (nearest tenth)

Step-by-step explanation:

The chord of length 4 is the base of an isosceles triangle with height of 3.7 and sides equal to the radius (x).

An isosceles triangle comprises two right triangles, each with:

base = 2 units
height = 3.7 units
hypotenuse = x units

Therefore, to find x use Pythagoras' Theorem: a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

⇒ a² + b² = c²

⇒ 2² + 3.7² = x²

⇒ x² = 17.69

⇒ x = √(17.69)

⇒ x = 4.2 (nearest tenth)
