Step 1: Rewrite equations

2x - 3y = 16
5x - 3y = 13

Step 2: To be able to eliminate, multiply the second equation by -1

-1(5x - 3y = 13) —> -5x+3y=-13

Step 3: Use the elimination method to solve, using new equation

2x-3y=16
-5x+3y=-13
_________
-3x=3

x=-1

Step 4: Using x, substitute it into an equation for y

2x - 3y = 16

2(-1) - 3y =16
-2 -3y =16
+2 +2
________
-3y=18

y=-6

Final answer: A) (-1,-6)

Situation:

Gala2k [10]

Answer:

5.5 days (nearest tenth)

Step-by-step explanation:

Given formula:

$\sf N=N_0e^{-kt}$

$\sf N_0$ = initial mass (at time t=0)
N = mass (at time t)
k = a positive constant
t = time (in days)

Given values:

$\sf N_0$ = 11 g
k = 0.125

Half-life: The time required for a quantity to reduce to half of its initial value.

To find the time it takes (in days) for the substance to reduce to half of its initial value, substitute the given values into the formula and set N to half of the initial mass, then solve for t:

$\begin{aligned}\sf N & = \sf N_0e^{-kt}\\\\\implies \sf \dfrac{11}{2} & = \sf 11e^{-0.125t}\\\\\sf \dfrac{1}{2} & = \sf e^{-0.125t}\\\\\sf \ln \left(\dfrac{1}{2}\right) & = \sf \ln e^{-0.125t\\\\\sf \ln \left(\dfrac{1}{2}\right) & = \sf -0.125t \ln e\\\\\sf \ln \left(\dfrac{1}{2}\right) & = \sf -0.125t(1)\\\sf t & = \sf \dfrac{\ln \left(\dfrac{1}{2}\right)}{-0.125}\\\\\sf t & = \sf 5.545177444...\\\\\sf t & = \sf 5.5\:\:days\:\:(nearest\:tenth)\end{aligned}$

Therefore, the substance's half-life is 5.5 days (nearest tenth).

Linear pair angles are

guajiro [1.7K]

Answer:

Step-by-step explanation:

Linear Pair Angles are always congruent because you can see that the parallel lines are cut by a transversal, which creates special angle pairs. The angles would be Alternate Exterior Angles; angles on opposite sides of a transversal but outside the two parallel lines form supplementary angle pairs. The angles also are Corresponding Angles.
