Which expression is the sun of cubes?

Mathematics
1 answer:
Nina [5.8K]3 years ago
7 0

Answer:

Step-by-step explanation: We have been given 4 expressions. We are asked to choose the expression that represents sum of cubes.

We know that sum of cubes is in form .

We can see that 1st and 2nd option has a negative sign. Therefore, these options cannot be sum of cubes.

Let us check 3rd and 4th options one by one.

We can rewrite our expression by writing terms as cubes:

Therefore, expression  is a sum of cubes.

In 4th expression, we can see that . We cannot represent it as a cube. Similarly, we cannot represent  as a cube. Therefore, 4th expression is not correct.

Line m in xy plane contains the points (2,4) and (0,1) which of the following is the equation of M
HACTEHA [7]

Answer:

The equation of line M in slope intercept form is    y=\frac{3}{2}x+1

The equation of line M in standard form is  3x-2y=-2

Step-by-step explanation:

step 1

Find the slope of line M

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(2,4) and (0,1)

substitute

m=\frac{1-4}{0-2}

m=\frac{-3}{-2}

m=\frac{3}{2}

step 2

Find the equation of the line M in point slope form

y-y1=m(x-x1)

we have

m=\frac{3}{2}

point\ (0,1)

substitute

y-1=\frac{3}{2}(x-0)

y-1=\frac{3}{2}x ----> equation in point slope form

step 3

Find the equation of line M in slope intercept form

y=mx+b

Isolate the variable y in the equation of the line in point slope form

y-1=\frac{3}{2}x

Adds 1 both sides

y=\frac{3}{2}x+1

step 4

Find the equation of the line M in standard form

Ax+By=C

where

A is a positive integer

B and C are integers

we have

y=\frac{3}{2}x+1

Multiply by 2 both sides

2y=3x+2

3x-2y=-2 ---> equation in standard form

Using a property of operations, what can you say about the sums of (-13.2) 8.1 and 13.2 (-8.1)
artcher [175]
No matter where the negative sign is, the product will always be negative, so is the number itself.

13.2(-8.1)=-106.92

twice of that would be -213.84.

first do the multiplying, then the adding(the adding of negative numbers, so it would be basically subtracting).
