Answer:
x = 10
Step-by-step explanation:
Use CPCTC (Corresponding parts of congruent triangles are congruent).
Set the ratios:
First, simplify. Combine like terms:
Next, cross multiply.
Isolate the variable, x. Divide 6.5 from both sides of the equation:
Check:
Plug in 10 for x (Your answer). Cross multiply, then simplify:
(True).

Hello :
answer : <span>D. (Y-1)=2(x+2)
because :
if x=1 ... y =7
if : x= -2 .... y= 1
the slope is : (1-7)/(-2-1) = -6/-3=2</span>
A = 8 C = 8
AC = C-A = 8-0 = 8
C=8 F = 20
CF = F-C = 20-8 = 12
so the ratio would be 8/12 which reduces to 2/3
answer is D
Answer: A coefficient is simply a variable that has a number with it. For example 2y has a coefficient. The coefficient is 2 because you will multiply 2 by y.
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
