Solve each system by the addition method.
bagirrra123 [75]

Answer:

(x, y) = (2, -1.5)

Step-by-step explanation:

x + 2y = -1

5x - 4y = 16

<=>

(2)x + (2)2y = (2)(-1)

5x - 4y = 16

<=>

2x + 4y = -2

5x - 4y = 16

<=>

7x = 14

<=>

x = 2

(*)x + 2y = -1

=> 2 + 2y = -1

=> 2y = -3

=> y = -1.5

=> (x, y) = (2, -1.5)

I don’t understand this
Dahasolnce [82]

Answer:

Yes

Step-by-step explanation:

Statement 1: If JK and LM bisect each other then, they divide each other in 2 equal parts.

So,

JP = PK [Because of statement 1]

MP = PL [Because of statement 1]

∠JPM = ∠LPK [Because they are vertically opposite angles]

So, ΔJPM ≅ to ΔKPL [By SAS congruence criteria of triangle]

(1.) decide if function f is invertible.
Lubov Fominskaja [6]
<span>a) f(n) is the number of students in your calculus class whose birthday is on the nth day of the year.

f(n) is not invertible because several different days, n, may have the same number of students, f(n). Then for one specific f(n) you cannot determine a unique n.

b) f(x) is the volume in litters of x kilograms of water at 4 degrees celsius.?

f(x) is invertible because each x gives a different f(x), then you can determine unambiguously which f(x) corresponds to each x.
