5x-4y=-18 and x-4y=6

Answers

Answer 1

Answer:

x = -6 and y = -3

Step-by-step explanation:

x- 4y =6

x =4y +6......(i)

5x -4y =-18

20y +30 - 4y = -18

16y = -48

y = -3

x = -12+6

x = -6

Answers

Answer:

29.) y = -1.5x - 20

30.) y = 6 - 3x

Step-by-step explanation:

29.) For parallel lines; M1 = M2

put the equation in the form y = mx + c

the equation becomes 2y = 14 - 3x

therefore y = 7 - 1.5x.

For the points, introduce another point; (x,y) and the initial (-6,-11)

(y - - 11) ÷ ( x - - 6) = -1.5

y+11 = -1.5x - 9

y= -1.5x - 20

30.) still following the same procedure, only that M1 × M2 = -1

M1 = 1/3, M2 = -3

(y + 9)/(x - 5) = -3

y + 9 = 15 - 3x

y = 6 - 3x

The big square is divided into 4 with a side length of 25cm. 2 small square side lengths make up the big squares.

25 * 2 =

What are the leading coefficient, constant term and degree, if any, of the algebraic expression -7

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

We know that the degree of a certain polynomial will be the largest degree of any term.

For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 7x⁵ has the highest exponent of x i.e. 5. Thus, the polynomial has a degree of 5.

We also know that the coefficient of the term with the largest degree of the polynomial is called the leading coefficient of the polynomial.

For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 7x⁵ has the highest degree of 5. Thus, the leading coefficient of the polynomial

will be 7.

We also know that the constant term of a polynomial has the degree zero. i.e. the term which involves no variable.

For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 3 does not have any variable involved in it. Thus, the constant term of the polynomial

will be 3.

Coming back to the question:

Given the expression

-7

As the expression has only 1 constant term i.e. -7 which does not involve any variable, hence the expression -7 has the degree zero.As the expression does not involve any variable, so it does not have any leading coefficient.As the expression contains only 1 term i.e. -7, and the term does not involve any variable. Thus, the expression has the constant term -7.

Answer:

leading coefficient: -7

constant term: -7

degree: 0

Juan has 35 pairs of shoes. Every week he gets rid of 3 pairs. After how many weeks
will he have less than 10 pairs of shoes?
I need the inequality

Answers

Answer: w < 9

Step-by-step explanation:

Answer:

9 weeks

Step-by-step explanation:

Divide the total pairs of shoes by how many you lose in a week and it will give you about how many weeks it'll take to get rid of all of the shoes:

35 / 3 = 11.67

Knowing your multiplication table is key for this! You will know that the best answer for this is 9 (and not 8 or 10) because...

3 x 8 = 24

3 x 9 = 27

3 x 10 = 30

Which will give you less than 10 pairs:

35 - 27 = 8

A paint color requires the ratio of green paint to yellow paint to be 4 : 9. A container of this paint has 36 pints of yellow paint. How many pints of paint are in the container all together? *

Answers

Answer:

16:36

Step-by-step explanation:

If the ratio is 4:9 and yellow paint is 36 that means you have multiple 9 by a number and that number would be 4 to get 36 and you just multiply 4 by 4 which is 16 and your new ratio will be 16:36

Answer:

16

Step-by-step explanation:

If the ratio is 4:9 and there is 36 pints of yellow then it would be 4:9=x:36. 36 divided by 9 is 4 so you would multiply 4 to 4 and get 16.

Which of the following is a true statement?
1. CM = CD
2. 2(AB) = AM
3. 2(MB) = AB
4. 1/2 (AM) = AB

Answers

Answer:

3. 2(MB) = AB

Step-by-step explanation:

1. This is not true because CM is less than CD.

2. This is not true because 2(AB) is greater than AM.

3. This is true because AB = 2(MB) or 2(AM).

4. This is not true because 1/2(AM) is less than AB.

Let's put some values on number 3 to check if it's, indeed, true.

Let's say AB's distance is 50 meters, then AM and MB should be half of it; that is: AM/MB = 25 meters. Let's check:

2(MB) = AB

2(25) = 50

50 = 50
