Mathematics
1 answer:
valentinak56 [21]3 years ago
7 0

Answer:

The equation of the Parallel line to the given line is  5x+y-7=0

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the line y = - 5x+4 and point (1,2)

The equation of the Parallel line to the given line is  ax+by+k=0

Given straight line  5x + y -4 =0

The equation of the Parallel line to the given line is  5x+y+k=0

This line passes through the point (1,2)

             5x+y+k=0

            5(1)+2+k=0

⇒              7+k=0

                   k =-7

<u>Final answer:-</u>

The equation of the Parallel line to the given line is  5x+y-7=0

Which decimal is greater: 0.347 or 0.437?
trapecia [35]

Answer:

0.437

Step-by-step explanation:

Decimals are read the same as whole numbers, starting with the first digit, which is the largest, to the right. So, to find the larger decimal you need to look at the first digit. If this digit is the same then continue to the right until there is a difference in the number. In this case, the first digit is different. Therefore, whichever has the larger first digit must be the greater one. Since 4 > 3, 0.437 must be greater than 0.347.

Find the product using model or drawing
antiseptic1488 [7]

Fraction multiplication involves multiplying the numerators and the denominators to get the numerator and the denominator of the product respectively

Please find the attached diagrams

1. \dfrac{2}{15}, 2. \dfrac{3}{8}, 3. \dfrac{1}{12}, 4. \dfrac{7}{21}, 5. \dfrac{3}{10}

6. 51, 7. 1, 8. 22, 9. \dfrac{36}{55}, 10. 5\dfrac{1}{3}

Reasons:

The process of multiplication of factors using a model includes;

  • Creating a table that have the number of rows and columns equal to the values in the denominator of the two fractions respectively
  • Shading the number of columns given by the numerator of the fraction that has a denominator equal to the number of columns in the table
  • Shading the number of rows given by the numerator of the  fraction that has a denominator equal to the number of rows in the table
  • Ensuring that the common area are shaded to a different color
  • Simplifying the result

1. \dfrac{2}{3}   \times \dfrac{1}{5} = \dfrac{2}{15}  

2. \dfrac{1}{2}   \times \dfrac{3}{4} = \dfrac{3}{8}

3. \dfrac{1}{4}   \times \dfrac{2}{6} = \dfrac{2}{24} = \dfrac{1}{12}

4. \dfrac{1}{7}   \times \dfrac{2}{3} = \dfrac{7}{21}

5. \dfrac{4}{8}   \times \dfrac{3}{5} = \dfrac{12}{40} = \dfrac{3}{10}

Second part

6. When calculating fractions, 'of' means to 'multiply by', therefore, we have;

\dfrac{17}{25}   \times 75= \dfrac{17}{25}   \times 25 \times 3 = 17 \times 3 =  51

7. \dfrac{7}{6}   \times \dfrac{24}{28} = \dfrac{7}{6}   \times \dfrac{6 \times 4}{7 \times 4} = \dfrac{7}{6}   \times \dfrac{6}{7 }  = 1

8. 12   \times 1\dfrac{5}{6} =6 \times 2   \times \dfrac{11}{6} =2   \times {11} = 22

9. \dfrac{4}{5}   \times \dfrac{9}{11} = \dfrac{4 \times 9}{5 \times 11} = \dfrac{36}{55}

10. 6\dfrac{2}{3}     \times \dfrac{12}{15} =\dfrac{20}{3}  \times \dfrac{12}{15} = \dfrac{4 \times 5}{3}  \times \dfrac{4 \times 3}{5 \times 3} = \dfrac{4}{3}  \times {4} = \dfrac{16}{3} = 5\dfrac{1}{3}
