Answer:

$120

Step-by-step explanation:

12 ears = $2

600 ears = ?

to determine the cost of 600easrsof corn we find the cost of 1 ears of corn first

1 ears = 2/12 =0.1666

= 0.2 approximately

so 600ears of corn = 0.2 × 600 =120

For your rock collection display, you want to have at most 25 samples.

mezya [45]

Answer:

$\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.$

The graph is attached.

Step-by-step explanation:

Let be "x" the number of metamorphic samples and "y" the number of sedimentary samples.

You know that you want to to have at most 25 samples, then:

$y\leq 25-x$

And you want to have at least 3 times as many sedimentary samples as

metamorphic samples, then:

$y\geq 3x$

Therefore, the system of inequalities that model the situation is:

$\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.$

The y-intercept of the line $y=25-x$ is:

$y=25-(0)\\\\y=25$

And the x-intercept is:

$0= 25-x\\\\x=25$

Knowing this, you can graph the line

The y-intercept of the line $y= 3x$ is:

$y=3(0)\\\\y=0$

And the x-intercept is:

$0= 3x\\\\x=0$

Knowing this, you can graph the line.

Observe the graph attached, where the solution of the system of inequalities is the intersection of the regions.

Find the slope to y=8/9x-9 and the y intercept

Liula [17]

$The \ general \ form \ of \ a \ straight-line \ equation \ is: \\\\ y=mx+b\\\\where \ "m " \ is \ the \ slope \ of \ the \ line \ and \ "b" \ is \ y -intercept \\ \\ y= \frac{8}{9}x-9 \\\\m=\frac{8}{9}\\b=-9 \\ \\Answer: \ Slope \ is \ equal \ to \ 6 \\ y-intercept \ is \ equal \ ( -9).$
