Answer:

(0, -6) is the y-intercept, (2, 0) is the x-intercept

<u>Skill(s) needed: Standard Form Evaluation</u>

Step-by-step explanation:

1) We are using standard form in this problem here, where you have Ax+By=C

2) Now, regarding the y-intercept, the y-intercept is when the line intersects with the y-axis, so when x=0.

----> (0,y_1)

3) In this scenario, we can plug in 0 for x, and solve for y to get the y-intercept. Let's see it below:

---> 27x-9y=54

--->  27(0)-9y=54

---> 0-9y=54

---> -9y=54

---> y=-6

Above, y=-6, so the y-intercept is (0, -6) (Note: This coordinate point is verbally defined as: When x equals zero, y equals negative six)

-------------------------------------------------------------------------------------------------------------- The x-intercept works the same way, it is the intersection with the x-axis, and is when y=0.

Plugging it in:

27x-9(0)=54 \\ 27x=54 \\ x=2

x equals two, when y =0, so (2,0) is the x-intercept

74 is a rational number but not a whole number. 74 is a whole number but not a rational number. 74 is a whole number and a ratio
Lady_Fox [76]

Answer:

Option C: 74 is both a whole number and a rational number.

Step-by-step explanation:

A rational number is defined as a number which can be written as a fraction of two integers, an integer, a whole number and a natural number. The integer could be positive or negative.

Examples include -1/4, 1/2, 12

So it's obvious that the given number of 74 is a rational number.

Now, a whole number is simply a non - negative integer.

An integer is a number that is not a fraction.

Thus, examples of whole numbers are 0, 1, 2, 3, 4...

So 74 is clearly a whole number.

Therefore, we can conclude that 74 is both a whole number and a rational number.

ST=<br> Help me please thank u
dmitriy555 [2]

Step-by-step explanation:

RS + ST = 8

(RS + ST)×RS = (4 + 2)×4

8 × RS = (4 + 2) × 4 = 6 × 4 = 24

RS = 24/8 = 3

RS + ST = 8

3 + ST = 8

ST = 5
