What is the constant of proportionality ​

Answer:

[tex]2x + y = 5 \\ y = 5 - 2x[/tex]

[tex]2x - y + = 5 \\ - y = 5 - 2x[/tex]

[tex]x + 2y = 5 \\ 2y = 5 - x \\ 2y = 4 x [/tex]

Answer:

  83 m

Step-by-step explanation:

The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...

  8.26(10 m) = 82.6 m ≈ 83 m

_____

The distance formula will tell you the distances are ...

  AC = √(3² +1²) = √10

  BD = √(5² +1²) = √26

The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.

Answer:

Step-by-step explanation:

[tex]f(3,7)=\frac{3+7}{2(3)+7}=\frac{10}{13}\\f(4,4)=\frac{4+4}{2(4)+4}=\frac{8}{12}=\frac{2}{3}\\f(1,5)=\frac{1+5}{2(1)+5}=\frac{6}{7}[/tex]

Answer:

7).

RT = RS + ST

[tex]10 = (2x - 20) + (2x - 18) \\ 10 = (2x + 2x) + ( - 20 - 18) \\ 10 = 4x - 38 \\ 4x = 10 + 38 \\ 4x = 48 \\ { \boxed{x = 12}}[/tex]

8).

LN = LM + MN

[tex](5x - 2) = 12 + (x + 2) \\ (5x - x) = 12 + 2 + 2 \\ 4x = 16 \\ { \boxed{x = 4}}[/tex]

Answer:

15

Step-by-step explanation:

f(x) = 5(2-x)

if f(-1)

f(-1) = 5(2-(-1))

= 5(2+1)

= 10 + 5

= 15

Answer:

wouldnt it be 7m

Step-by-step explanation:

Answer:

7m

Step-by-step explanation:

3(x)m + 4(x)m = 7(x)m

m is the same value so were adding 3+4 which is 7

an example:

lets say m = 2

ur question is now 3(x)2 +4(x)2 = 7(x)2

3x2 = 6  

4x2=8

6+8= 14

7x2 = 14

Answer:

28

Step-by-step explanation:

-7 x 2 = -14

-14 x -2 = 28

Answer:

C. 28

Step-by-step explanation:

(-7)(2) = -14

(-14)(-2) = 28

Two negatives make a positive.

Answer:

2754

Step-by-step explanation:

Given,

Length = 18 yards is equivalent to 54 feet

Width = 51 feet

So area of the field = Length * width

= 54 x 51

=2754 square feet

Answer:

  no

Step-by-step explanation:

The two short sides, 1 and 2, do not have a sum greater than the long side, 5, so these lengths do not form any sort of triangle.

__

Lengths 1, 2, √5 satisfy the Pythagorean theorem, so will form a right triangle.

  1² +2² = (√5)²

  1 + 4 = 5 . . . . . . Pythagorean theorem is satisfied

Answer:

  B. The substitution method is the best choice because one of the variables in one equation has a coefficient of 1

Step-by-step explanation:

We find the easiest choice to be using a graphing calculator (see attached). It shows the solution to be (x, y) = (94, 234).

__

The only coefficient with a magnitude of 1 is the coefficient of y in the second equation. That coefficient is -1, not 1. The only coefficients related by an integer are the coefficients of y: the coefficient of y in the first equation is a multiple of that in the second equation.

Strictly speaking, none of the answer choices matches the reasoning.

__

We could use substitution, because the coefficient of y in the second equation is -1.

  y = 2x+46

  5x -2(2x +46) = 2

  x = 2+92 = 94

  y = 2(94) +46 = 234

The solution by substitution is (x, y) = (94, 234).

__

We could use elimination, because the coefficient of y in the first equation is a multiple of the coefficient of y in the second equation.

  (5x -2y) -2(2x -y) = (2) -2(-46)

  x = 94 . . . . . . simplified

  2(94) -y = -46 . . . . substitute into the second equation

  y = 2(94) +46 = 234

The solution by elimination is (x, y) = (94, 234).

_____

Additional comment

Here, I like the substitution best, because once we solve for y, we can use that with our solution for x. It seems like less work than using the elimination method, though both solutions are shown here in 4 lines.
