Solve the system of equations using the elimination method. 2x - 3y = 50; 7x + 8y = -10

Klio2033 [76]

Answer:

x=10

y=-10

Step-by-step explanation:

multiply first row by 7

14x−21y=350

7x+8y=−10

multiply second row by 2

14x−21y=350

14x+16y=−20

subtract the first row by the second row

−37y=370

solve for y

y=−10

substitute y=-10

14x−21×−10=350

solve for x

x=10

and thats your answer

x=10

y=-10

The number of bacteria in a certain population increases according to an exponential growth model, with a growth rate of 3.5% pe

uysha [10]

Generic exponential growth model: y = Ao[1+r]^t

In this case: r = 3.5% = 0.035

y = 2Ao .....[the double of the initial value]

Then: 2Ao =Ao (1 + 0.035)^t

(1.035)^t =2

Take logarithm to both sides

t ln(1.035) = ln(2)

t = ln(2) / ln(1.035) = 0.693 / 0.0344 = 20.15

Answer: 20.15 hours.

A swimming pool is being drained at a constant rate of 3 inches (depth of the water) per hour. The depth of the water after 5 ho

Blababa [14]

Answer:

y-32=3(x-5)

Step-by-step explanation:

The swimming pool is being drained at a constant rate of 3 inches per hour, therefore:

The rate of change, Slope, m=3 inches per hour

If the depth of the water after 5 hours is 32 inches.

The depth is the dependent variable(as its values varies with time) while the time is the independent variable, we can write this as a pair (x,y)=(5, 32).

The point slope form of the equation of a line is of the form: $y-y_1=m(x-x_1)\\(x_1,y_1)=(5,32), m=3\\$Substituting these values, we obtain:\\y-32=3(x-5)\\This is the equation of the function in point slope form.$
