Answer:
y = -3.5x + 15
Step-by-step explanation:
Your slope-intercept equation is always y = mx + b
Using this formula, we need to find slope first: m = (y2-y1) / (x2-x1)
Step 1: Find slope
m = (1-8) / (4-2)
m = -7/2
Step 2: Plug in into slope-intercept form
y = -3.5x + b
Step 3: Find <em>b </em>(Plug in a coordinate given)
1 = -3.5(4) + b
1 = -14 + b
b = 15
Step 4: Combine it all together
y = -3.5x + 15
And you have your final answer.

Step-by-step explanation:
A polynomial is the sum of terms with variables having positive integer exponents. Coefficient numbers need not be integers.
The term 3/x^4 = 3x^-4 is not such a term, so the expression containing it is not a polynomial.
Answer:
x = 84
y = 96
Step-by-step explanation:
Alternate interior angles are a pair of nonadjacent interior angles that are on opposite sides of the transversal. Alternate interior angles are equal.
Therefore, x = y - 12
Angles on a straight line add up to 180°
Therefore, x + y = 180
Substituting x = y - 12 into x + y = 180 and solve for y:
⇒ y - 12 + y = 180
⇒ 2y - 12 = 180
⇒ 2y = 192
⇒ y = 96
Substitute found value for y into x = y - 12 and solve for x:
⇒ x = 96 - 12
⇒ x = 84
Answer:
This system have 9000 different numbers.
Step-by-step explanation:
We know that the internal telephone numbers in the phone system on a campus consists of 4 digits, with the 1st not equal to 0.
We have total 10 digits.
In the first place we have 9 possibilities, because from the conditions of the task in the first place there cannot be 0.
In second, third and fourth place we have 10 possibilities.
Therefore, we get
This system have 9000 different numbers.
