Answer: 87.5%
Step-by-step explanation:
From the question, we are informed that a rancher uses 1400 acres of his property for cattle grazing amd that the area of the property is 1600 acres. To get the percentage used for cattle grazing, we divide 1400 by 1600 and then multiply the result by 100%. Mathematically, this will be expressed as:
= 1400/1600 × 100
= 0.875 × 100%
= 87.5%
The percent that is used for cattle grazing is 87.5%.
The correct option regarding whether the relation is a function is:
B. The relation is a function. Each input value is paired with one output value.
<h3>When does a relation represent a function?</h3>
A relation represent a function if <u>each value of the input is paired with one value of the output</u>.
In this problem, when the input - output mappings are given by:
{(–2, 3), (–1, 3), (0, 2), (1, 4), (5, 5)}.
Which means that yes, each input value is paired with one output value, hence the relation is a function and option B is correct.

Answer:
y = 3x + 30
Step-by-step explanation:
This is what the table should look like.
Number of Bars Sold (x) Total Earnings (dollars) (y)
0 30
1 33
2 36
3 39
When x = 0, y = 30. The point (0, 30) is the y-intercept.
As x goes up by 1, from 0 to 1, from 1 to 2, from 2 to 3, y goes up by 3, from 30 to 33, from 33 to 36, from 36 to 39.
A change of 1 in x results in a change of 3 in y.
That is a slope of 3 since
slope = (change in y)/(change in x)
The equation of a line in slope-intercept form is
y = mx + b
We have m = 3 and b = 30, so the equation is
y = 3x + 30
Answer: 3x + 30
C.
if it was wrong i’m very sorry
The answer is D! good luck
