Got a fairly simple looking system of equations, 2k+4y=20, and 3x+6y=30 Don't understand how to prove what values of k provide -
Leya [2.2K]

Answer:

2kx+4y=20 ⇒ kx+2y=10

3x+6y=30 ⇒ x+2y= 10

k is the coefficient of x, so it is the slope of the line

  • when k=1, both equations will be same, then there are many solutions
  • when k=0 there is one solution
  • when k is anything different, then the lines will be parallel, so no solutions

Analyze the diagram below and complete the instructions that follow.
Phantasy [73]

Answer:

Option (B)

Step-by-step explanation:

From the figure attached,

ΔBCD and ΔACE are the similar triangles.

Therefore, by the property of similar triangles, corresponding sides of these similar triangles will be proportional.

\frac{AC}{BC}= \frac{EC}{DC}

\frac{AB+BC}{BC}= \frac{ED+DC}{DC}

\frac{AB+6}{6}= \frac{24+8}{8}

\frac{AB+6}{6}= \frac{32}{8}

\frac{AB+6}{6}=4

AB + 6 = 24

AB = 18

Option (B) will be the answer.
