Answer:

(7,-3)

Step-by-step explanation:

y = -3

substitute in the first equation

3x - y^2 = 12

3x - (-3)^2 = 12

3x - 9 = 12

3x = 12 + 9

3x = 21

x = 7

Nutka1998 [239]

let's plug the value of x and y as 5 and 4 respectively to find the value of given expression :

$7 {y}^{2} + 15x - 22$

$7(4) {}^{2} + (15 \times 5) - 22$

$(7 \times 16) + 75 - 22$

$112 + 53$

$165$

The population of bacteria in a certain culture can be modeled by the function P(t)=10000(1.03)^t. Is the population of bacteria

ch4aika [34]

Answer:

The population of bacteria is increasing.

Step-by-step explanation:

The function modelling the population of bacteria in the given culture is an exponential function; We have a base 1.03 and an exponent t. An exponential function is said to be increasing if the base is strictly greater than 1, this implies that the population of the bacteria is increasing as t increases from 0 to infinity.
