Answer:
Step-by-step explanation:
The line rises to the left so the slope is negative.
The slope m = -24/12 = -2.
Using the point-slope formula and taking the point (12, 0) on the line:
y - y1 = m(x - x1) where m = -1, x1 = 12 and y = 0:
y - 0 = -2(x - 12)
y = -2x + 24 <------- this is the required equation.
first, I would round down/up 21.25 to just 21, 19.89 to 20, and 6.52 to 7. then add up 21+20=41, 41+7=48 so 48 is the answer
The side of the edge of the cube is 7. 07cm
<h3>How to determine the length</h3>
Given that a diagonal of a cube measures the square root of 150 cm and the diagonal of a face measures 10 cm.
Let's find the edge of the face
Note that the face of the cube is in the shape of square .
The diagonal of the face is 10 cm.
The formula for diagonal of square =
a is the side of the square face
We have that,
Make 'a' subject of formula
a =
Find the surd of the equation, we have
a = ×
a =
a =
a =
Thus, the side of the edge of the cube is 7. 07cm

To find the slope given two points, you need to subtract the two y values over the two x values
(-5,-3) (9,-6)
-5 will be x1, and -3 will be y1. 9 will be x2, and -6 will be y2. You then need to put the numbers in the correct place in the equation.
y2-y1 -6-(-3) -9
-------- = -------- = ----
x2-x1 9-(-5) 14
Now that we have the slope (-9/14) you can use one of the coordinates to find the value of b.
Let's use (9,-6).
-6=-9/14(9)+b
-6=-81/14+b
+81/14
b=-3/14
Your final equation is y=-9/15x-3/14
