Find the x and y intercepts for the following equation. 2x– 7y=-14
Kisachek [45]

Answer:

C: Xint = 2, Yint. = -7

Step-by-step explanation:

Given the equation, 2x - 7y = -14:

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0.  To solve for the y-intercept, set x = 0:

2x - 7y = -14

2(0) - 7y = -14

0 - 7y = -14

-7y = -14

Divide both sides by -7 to solve for y:

-7y/-7 = -14/-7

y = 2

Therefore, the y-intercept = 2.

Next, the x-intercept is the point on the graph where it crosses the x-axis, and has coordinates, (a, 0). To find the x-intercept, set y = 0 and substitute into the given equation:

2x - 7y = -14

2x - 7(0) = -14

2x - 0 = -14

2x = -14

Divide both sides by 2 to solve for x:

2x/2 = -14/2

x = -7

x-intercept = -7.

Therefore, the correct answer is C: Xint = 2, Yint. = -7

Step-by-step explanation:

x/3/9 = 5/9

x : 3 : 9 = 5/9

x×1/3×1/9 = 5/9

x/27 = 5/9

x = 5×27/9

x = 5×3

x = 15

A sample of Iron-59 contains 50 mg. One hundred days later, the sample contains 10.75 mg. What is the half-life of iron-59, in d
exis [7]

Answer:

t_{1/2}=45.09 d    

Step-by-step explanation:

We can use the decay equation:

M=M_{0}e^{-\lambda t}

  • M(0) is the initial mass
  • M is the mass after t (1000 days) time
  • λ is the decay constant

But:

\lambda = ln(2)/t_{1/2}

  • t(1/2) is the half-life.

So, we can rewrite the initial equation:

M=M_{0}e^{-\frac{ln(2)}{t_{1/2}}t}

Now, we just need to solve it for t(1/2):

ln(\frac{M}{M_{0}})=-\frac{ln(2)}{t_{1/2}}t

t_{1/2}=-\frac{ln(2)}{ln(\frac{M}{M_{0}})}t

t_{1/2}=-\frac{ln(2)}{ln(\frac{10.75}{50})}100                

t_{1/2}=45.09 d    

I hope it helps you!
