well first you have to multiply 6 by 1/4 and then you have to do this: 1.5*1.5*1.5*1.5 to get your answer i think....

Answer:

Step-by-step explanation:

you have to distributw the 4 to the 1/4 so essentially youre multiplying the exponents. think of it as 4*1/4 and youll have 4/4 which equals to 1. 6^1 is just 6 so thats the answer

Which of the following lines is not parallel to the graph of y = 4x +7?

Bas_tet [7]

Answer:

c. 4y -x = 8

Step-by-step explanation:

Each of the equations can be put into slope-intercept form (solved for y) as follows:

a: y = 4x +9

b: y = 4x -8

c: y = (1/4)x +2

d: y = 4x -4

___

The equations containing the term "4x" all describe parallel lines. The equation containing (1/4)x describes a line that intersects the given line. It is not parallel to the others.

1) Write the equation parallel to the following equations that would go through (2,7):

myrzilka [38]

Note: Your option 'b' is somewhat ambiguous, so I am assuming you meant to write the equation y=2x+3 for the 'b' option.

Answer:

the equation y = 2x + 3 has slope m=2 and the y-intercept is 3, and also PASSES through the point (2, 7).

Step-by-step explanation:

An equation parallel to the given line equation will have the same slope.

Given the point (2, 7) from which the equation passes through.

so checking all the equations in the options to check whether any equation passes through or not.

Checking the option 'a':

y = 3x - 2

Putting (2, 7)

7=3(2)-2

7=6-2

7=4

L.H.S is not equal to R.H.S

Therefore, the option 'a' is NOT correct.

So, the equation y = 3x - 2 will NOT PASS through the point (2, 7)

Checking the option 'b':

y = 2x + 3

Putting (2, 7)

7=2(2)+2

7=7

L.H.S is equal to R.H.S

Therefore, option 'b' is the CORRECT option.

So, the equation y = 2x + 3 will PASS through the point (2, 7)

Checking the option 'c':

y = x-6

Putting (2, 7)

7=2-6

7=-4

L.H.S is not equal to R.H.S

Therefore, the option 'c' is NOT correct.

So, the equation y = x-6 will NOT PASS through the point (2, 7)

Checking the option 'd':

y + 2x = 8

Putting (2, 7)

7+2(2)=8

7+4=8

11=8

L.H.S is not equal to R.H.S

Therefore, the option 'd' is NOT correct.

So, the equation y + 2x = 8 will NOT PASS through the point (2, 7)

Therefore, considering the above analysis, we conclude that:

Option 'b' is the CORRECT option.

So, the equation y = 2x + 3 will PASS through the point (2, 7).

also

The slope-intercept form of the equation is

$y=mx+b$

where m is the slope and b is the y-intercept.

Therefore, the equation y = 2x + 3 has slope m=2 and the y-intercept is 3, and also PASSES through the point (2, 7).

The volume of a rectangular prism is (x4 + 4x3 + 3x2 + 8x + 4), and the area of its base is (x3 + 3x2 + 8). If the volume of a r

vfiekz [6]

Answer:

$Height = x \frac{x^3+3x^2+4}{x^3+3x^2+8}$

Step-by-step explanation:

$Volume = Base \ Area\ * Height$

$Height = \frac{Volume}{Base \ Area}$

Where $Volume = x^4+4x^3+8x+4$ and $Area = x^3+3x^2+8$

Putting in the formula

$Height = \frac{x^4 + 4x^3 + 3x^2 + 8x + 4}{x^3 + 3x^2 + 8}$

Doing long division, we get

$Height = x + \frac{x^3+3x^2+4}{x^3+3x^2+8}$

$Height = x \frac{x^3+3x^2+4}{x^3+3x^2+8}$

This is the simplifies form and it can't be further simplified.

What is the surface area of the pyramid?

-Dominant- [34]

Answer:

166 square units

Step-by-step explanation:

Let’s find the area of the shapes that in the net.

First, we can see two of the triangles have a base of 2 and a height of 13. The formula for surface area of a triangle is bh÷2. (13x2)÷2=13. Since there are two triangles, we multiply 13 by 2 and get 26.

Second, we can see two of the triangles have a base of 10 and a height of 12. (10x12)÷2=60. Since there are two triangles, we multiply 60 by 2 and get 120.

Third, we can see a rectangle has a base of 10 and a height of 2. The formula for surface area of a rectangle is bh. 10x2=20.

Last, we add up all the areas:

20+120+26=166.
