QUESTION 6

18xy = 2 \times  {3}^{2}  \times x \times y

36 {y}^{2}  =  {2}^{2} \times  {3}^{2}   \times  {y}^{2}

The greatest common factor is the product of the least powers of the common factors;

GCF=2 \times  {3}^{2}  \times y

GCF=18y

15a = 3 \times 5 \times a

28a {b}^{2}  =  {2}^{2}  \times 7 \times a \times  {b}^{2}

GCF=a

QUESTION 9

24 {d}^{2}  =  {2}^{3}  \times 3 \times  {d}^{2}

30 {c}^{2} d = 2 \times 3 \times 5 \times d

GCF=2 \times 3 \times d

GCF=6d

QUESTION 10

20gh =  {2}^{2}  \times 5 \times g \times h

36 {g}^{2}  {h}^{2}  =  {2}^{2}  \times  {3}^{2}  \times  {g}^{2}  \times  {h}^{2}

GCF= {2}^{2}  \times g \times h

GCF=4gh

QUESTION 11

17 {c}^{3}  {d}^{2}  = 17 \times  {c}^{3}  \times  {d}^{2}

5 {c}^{2}  {d}^{2}  = 5 \times  {c}^{2}  \times  {d}^{2}

GCF= {c}^{2}  \times  {d}^{2}

GCF= {c}^{2}{d}^{2}

If a line contains the point (0, -1) and has a slope of 2, then which of the following points also lies on the line?
larisa86 [58]
The answer is B. because if you make an equation in the form y=mx+b then you can solve the equation by inputting x where x goes in the equation and solving. BTW the equation would be y=2x-1
