Answer:
15 white cubes
Step-by-step explanation:
Given
Required
Determine the number of white cubes needed to represent 0
To solve this question, we make use of the following equation.
If there are 15 black cubes, the the 15 black cubes is worth: +1 * 15
Substitute +1 * 15 for the Black Cubes
Collect Like Terms
Recall that 1 white cube is worth -1
So, the number of white cubes is:
<em>Hence, the student needs 15 white cubes</em>
The answer is (4,-1). The reason why is because if you graph the three coordinates you have, the place where the the coordinates meet that you don't have a coordinate is (4,-1).
I hope this helps.
I would say A because tyler is walking faster
The equation for slope intercept is y=mx+b
M represents the slope of the equation while b represents the y-intercept.
Slope formula is y2-y1/x2-x1
The slope would be 2/3
Plug in the slope and the equation would be y=2/3x+b
Now you need to find the intercept, choose on of the coordinates and plug it into the equation. I chose (6,-1)
The final equation would be y=2/3x-5
We write system of equations:
O = 5*a
P = 15*a
a,b,c =?
------------------
a + b + c = 5a b + c = 4a
a*b/2 = 15a b/2 = 15
Now we calculate b and remaining sides:
b = 30
30 + c = 4a
c^2= 30^2 + a^2
(4a - 30)^2 = 900 + a^2
16a^2 - 240a + 900 = 900 + a^2
15a^2 = 240a
a = 16
that means that c = 4*16-30 = 34
