First, write it out in point-slope form and then simplify it to slope-intercept form.
(y+5)=2(x-2)
y+5=2x-4
y=2x-9
The answer is D.

The diagram show a 5cm x 6cm x 7cm cuboid pls help you
kotegsom [21]

Answer:

d ≈ 10.5

Step-by-step explanation:

The formula for the diagonal of a retangular prism (cuboid) is

d=\sqrt{l^2+w^2+h^2}

1.) Plug in all the values for l, w, and h

d=\sqrt{5^2+6^2+7^2}

2.) simplify by squaring the terms inside the square root

5 * 5 = 25

6 * 6 = 36

7 * 7 = 49

d=\sqrt{25+36+49}

3.) Add the terms

d=\sqrt{110}

4.) Simplify

d = 10.488

5.) Round to one decimal place

d ≈ 10.5

Graph the linear equation
baherus [9]
For the equation
.. x - y = 4
you can divide by 4 to put the equation into intercept form. This form shows you both interecepts at once.
.. x/4 +y/(-4) = 1

The x-intercept is (4, 0).
The y-intercept is (0, -4).

The graph is shown below.
