Answers
Answer:
m=2
Step-by-step explanation:
6m - 8 = 1/2(-4m + 16)
Distribute
6m -8 = -2m +8
Add 2m to each side
6m-8+2m = -2m +8+2m
8m -8 = 8
Add 8 to each side
8m-8+8 = 8+8
8m = 16
Divide each side by 8
8m/8 = 16/8
m=2

ed made a large cube by gluing together a number of identical small cubes together
Answers
Answer:
thats cool not realy a question tho can I have brainlest
Step-by-step explanation:
Ed painted 95 faces of a large cube.
What is the Cubic equation?Cubic equations are polynomials of degree 3. That means the maximum degree of the polynomial is three.
And the standard form of the cubic equation is;
f(x) = ax³ + bx² +cx +d, where a, b, c, and d are constant coefficients a ≠ 0.
Let's assume that the original cube that Ed made had n small cubes along each edge.
Then the total number of small cubes in the large cube is n³.
Let p be the number of faces that Ed painted.
Each small cube has 6 faces, and if a face is painted, it will not be visible after the large cube is assembled.
So the total number of unpainted faces is 6n³ - p.
When Nicole drops the cube, each small cube will be separated from the others, and all painted faces will become visible.
So the total number of painted faces is equal to p minus the number of small cubes that don't have any painted faces, which is 45.
Therefore, we have a cubic equation:
p - 45 = 6n³ - p.
Simplifying this equation, we get:
2p =6n³ + 45
p = 3n³ + 22.5
We know that p is an integer, so 3n³ + 22.5 must be an integer.
This means that n³ must be a multiple of 2/3.
The smallest integer value of n that satisfies this condition is n = 3.
So Ed made a cube with 3 small cubes along each edge, and he painted:
the value of the cubic equation at 27,
p = 3n³ + 22.5 = 3(27) + 22.5 = 94.5 ≈ 95 faces of the large cube.
Therefore, 95 faces of the large cube.

The complete question:
Ed made a large cube by gluing together a number of small identical cubes and then he painted some of the faces of the large cube. His sister Nicole dropped the cube and it broke into the original small cubes. 45 of these small cubes didn't have any painted faces. How many faces of the large cube did Ed paint?

How do you solve:
g(x) = x - 2
( I think the answer is 2 but how?!)
Answers
Answer:
x-2 =0
x=2
Step-by-step explanation:
we take -2 to the anther side it becomes 2
Answer:
-2
Step-by-step explanation:
A function is a rule for working out the values y for the given values x
For example, h = 3x and y = x^2 are functions. The notation g(x) is read as g of x. g is the function. g(x) = 3x means the function of x is 3x
So, when solving to find the value of x, you must substitute x for any given value.
For example, f(x) = 10/x. Work out f(5), you must substitute the 5 into the denominatior of the fraction 10/x . This becomes 10/5, which equals to 2.
But for your question, to find the value of x, substitute x with 0
You end up with -2

Answers
Answer:
y ≤ -2x - 2
Step-by-step explanation:
Slope- intercept form is y = mx + b, m being the slope and b being the y-intercept.
The slope is the rise of the line over the run. We can choose two points that are exactly on the line. Let's try points (-1, 0) and (0, -2). The line slopes down, so we already know the slope is negative. From point (-1, 0), the line goes down 2 units and over 1 unit. So, the slope is -[tex]\frac{2}{1}[/tex]. We can also simply say that the slope is -2.
The line intersects with the y-axis at point (0, -2), so the y-intercept is -2.
Because the shading is on the left side of the line and the line is solid, we can tell that y is less than or equal to -2x - 2. So, the equation is-
y ≤ -2x - 2

Answers
Answer:
With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:
C(x)=20+4x,where:
x is the number of rides
The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.
