Answer:

  a: y = x

  b: y = 2/3x

Step-by-step explanation:

A proportional relationship is described by the equation ...

  y = kx

The value of the constant k can be found from any (x, y) pair:

  k = y/x . . . . . divide both sides of the above equation by x

__

Line 'a' goes through the point (1, 1), so we have ...

  k = 1/1 = 1

  y = x . . . . . . . the coefficient 1 is not shown. Equation for line a.

__

Line 'b' goes through the point (3, 2), so we have ...

  k = 2/3

  y = 2/3x . . . . . . Equation for line b.

answer is B. 53
-------------
2x = 8
  x = 4

answer
D. 4

--------------
y = 3x (1)
y + 12 = 6x so y = 6x - 12 (2)
from (1) and (2) you haev
3x = 6x - 12
3x = 12
  x = 4
y = 4x = 4(3) = 12

answer
C. y = 12

1/7 divided by blank equals 14
kherson [118]

Answer:

1/98

Step-by-step explanation:

Step 1: Translate statement into equation.

  • \frac{1}{7}/x = 14
  • \frac{1}{7x}=14

Step 2: Multiply both sides by 7x.

  • \frac{1}{7x} * 7x = 14 * 7x
  • 1 = 98x

Step 3: Divide both sides by 98.

  • \frac{1}{98} =\frac{98x}{98}
  • x = \frac{1}{98}

Step 4: Check if solution is correct.

  • \frac{1}{7}/\frac{1}{98}
  • \frac{1}{7}*98
  • 14

Therefore, the answer is 1/98.

What is the length of ?<br><br> 3 ft<br> 4 ft<br> 9 ft<br> 18 ft
zmey [24]
Answer:
AC = 18 ft

Explanation:
There is a geometric theorem that states that:
" In a triangle, the line joining two midpoints of two sides is parallel to the third side and equals have its length"

Now, let's check the given triangle:
M is the midpoint of AB
N is the midpoint of BC

Based on the above theorem:
MN will be parallel to AC
and
length of MN = (1/2) * length of AC

We are given that:
length of MN = 9 ft
Therefore:
9 = (1/2) * length of AC
length of AC = 2 * 9 = 18 ft

Hope this jhelps :)
