Answer:

=8p−7.25

Step-by-step explanation:

=(5)(p)+(5)(−1)+(3)(p)+(3)(−0.75)

=5p+−5+3p+−2.25

=5p+−5+3p+−2.25

=(5p+3p)+(−5+−2.25)

=8p+−7.25

92 - 16b = 12 help please
Reptile [31]

Answer:

b = -6.5

Step-by-step explanation:

92 - 16b = 12

now you want to get the number(s) and variables on different sides

92 - 16b - 92 = -16b

12 + 92 = 104

-16b = 104

now divide each side by -16

-16b / -16 = b

104 / -16 = -6.5

b = -6.5

The lines are parallel. Find the slope-intercept form of the equation y₂.
Bas_tet [7]
Since the lines are parallel and you know the slope of y_{1} is -2, you know the slope of line y_{2} will also be -2. You can see on the coordinate grid that line y_{2} crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get y_{2} = -2x - 1.

Which expression is a difference of cubes? 9w^33-y^12 18p^15-q^21 36a^22-b^16 64c^15- a^26
LiRa [457]

we know that

A polynomial in the form a^{3}-b^{3} is called adifference of cubes. Both terms must be a perfect cubes

Let's verify each case to determine the solution to the problem

<u>case A)</u> 9w^{33} -y^{12}

we know that

9=3^{2} ------> <u>the term is not a perfect cube</u>

w^{33}=(w^{11})^{3} ------> the term is a perfect cube

y^{12}=(y^{4})^{3} ------> the term is a perfect cube

therefore

The expression 9w^{33} -y^{12} is not a difference of cubes because the term 9 is not a perfect cube

<u>case B)</u> 18p^{15} -q^{21}  

we know that

18=2*3^{2} ------> <u>the term is not a perfect cube</u>

p^{15}=(p^{5})^{3} ------> the term is a perfect cube

q^{21}=(q^{7})^{3} ------> the term is a perfect cube

therefore

The expression 18p^{15} -q^{21} is not a difference of cubes because the term 18 is not a perfect cube

<u>case C)</u> 36a^{22} -b^{16}

we know that

36=2^{2}*3^{2} ------> <u>the term is not a perfect cube</u>

a^{22} ------>  <u>the term is not a perfect cube</u>

b^{16} ------> <u>the term is not a perfect cube</u>

therefore

The expression 36a^{22} -b^{16} is not a difference of cubes because all terms are not perfect cubes

<u>case D)</u> 64c^{15} -a^{26}

we know that

64=2^{6}=(2^{2})^{3} ------>  the term is a perfect cube

c^{15}=(c^{5})^{3} ------>   the term is a perfect cube

a^{26} ------> <u>the term is not a perfect cube</u>

therefore

The expression 64c^{15} -a^{26} is not a difference of cubes because the term a^{26} is not a perfect cube

I'm adding a new case so I can better explain the problem

<u>case E)</u> 64c^{15} -d^{27}

we know that

64=2^{6}=(2^{2})^{3} ------>  the term is a perfect cube

c^{15}=(c^{5})^{3} ------>   the term is a perfect cube

d^{27}=(d^{9})^{3} ------>  the term is a perfect cube

Substitute

64c^{15} -d^{27}=((2^{2})(c^{5}))^{3}-(d^{9})^{3}

therefore

The expression 64c^{15} -d^{27} is a difference of cubes because all terms are perfect cubes
