Answer:
∠DCE is congruent to ∠CBA by the Vertical Angles Theorem and 15 over 5 equals 12 over 4 shows the corresponding sides are proportional; therefore, ΔABC ~ ΔEDC by the SSS Similarity Postulate.
Step-by-step explanation:
Answer: f(2) = 6
Step-by-step explanation: In this problem, we are given the function
f (x) = (x + 1) 2 and we are asked to find f(2). In other words, if we put an "x" into our function, we get a (x + 1) 2 out.
f we put a 2 into the function, we get f(2) = (2 + 1) 2 out. Now all we have to do is simplify on the right side.
2 + 1 gives us 3 and if we multiply 3 by 2, we get a product of 6.
Therefore, f(2) is 6.
Answer:
62.2x=y
Step-by-step explanation:
cost/ticket (c)
5000c = 311000
c = $62.20
Minust 5x both sides
7x-5x<5x-5x-8
2x<-8
divide by 2 both sides
x<-4
Answer:
They are identical triangles.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
The triangle with 39 and 90 has a missing angle of 51 degrees, and the triangle with 51 and 90 vice versa.
