Answer: a=4
b=1600x
Step-by-step explanation:
<u> 8b - 7 = 7b - 2</u>
Subtract 7b from each side: b - 7 = -2
Add 7 to each side: <em> b = 5</em>
Answer:
C. AC/BC = DF/EF
Step-by-step explanation:
Hi en that ∆ABC ~ ∆DEF, the corresponding sides of ∆ABC and ∆DEF would be proportional to each other.
AB corresponds to DE
AC corresponds to DF
BC corresponds to EF
Therefore,
hypotenuse over one of the leg of ∆ABC = hypotenuse over one of the corresponding legs of ∆DEF, which is:
AC/BC = DF/EF

Answer:
A) infinite solutions
Step-by-step explanation:
Simplify the equation.
4x -5 = 4x -5
This is true for all values of x, so there are an infinite number of solutions.
You want to use the Pythagorean Theorem: a squared+b squared=c squared
