Answer:

B. domain is all integers 0 through 9

Step-by-step explanation:

Domain values area usually plotted along the horizontal axis. In this case, the number of days is the domain of the of the function.

The domain of the function that is plotted on the graph ranges from 0, 1, 2 to 9.

1, 2, 3 to 9 are all integers. Therefore, we can conclude that the "domain is all integers 0 through 9."

Determine the ordered pair that satisfies the equation, 6x - 3y = 5.

Kazeer [188]

Given the equation $6x-3y=5.$

Check all options:

A. $\left(9,\dfrac{16}{3}\right)$ , this means that $x=9, y=\dfrac{16}{3}.$ Substitute these numbers into the left side of the equation equation:

$6\cdot 9-3\cdot \dfrac{16}{3}=54-16=38\neq 5.$

This option is false.

B. $\left(6,-3\right)$ , this means that $x=6, y=-3.$ Substitute these numbers into the left side of the equation equation:

$6\cdot 6-3\cdot (-3)=36+9=45\neq 5.$

This option is false.

C. $\left(1,-\dfrac{11}{3}\right)$ , this means that $x=1, y=-\dfrac{11}{3}.$ Substitute these numbers into the left side of the equation equation:

$6\cdot 1-3\cdot \left(-\dfrac{11}{3}\right)=6+11=17\neq 5.$

This option is false.

D. $\left(-2,-\dfrac{17}{3}\right)$ , this means that $x=-2, y=-\dfrac{17}{3}.$ Substitute these numbers into the left side of the equation equation:

$6\cdot (-2)-3\cdot \left(-\dfrac{17}{3}\right)=-12+17=5.$

This option is true.

Answer: correct choice is D.

Which represents the solution(s) of the graphed system of equations, y = x2 + 2x – 3 and y = x – 1?

aev [14]

Answer:

y = -4/3 x=-1/3

Step-by-step explanation:

y = x2 + 2x – 3 and y = x – 1

y= (y + 1)2 + 2(y + 1) - 3 and x= y+ 1

y= 2y + 2 + 2y +2 and x= y+ 1

-3y = 4 and x= y+ 1

y = -4/3 and x = (-4/3) + 1 = -1/3

x2 is x squared or x multiplied by two
