Answer:
slope = -1.5
Step-by-step explanation:
A set of three or more points are said to be collinear if they all lie on the same straight line.
We have been given the following collinear set of points;
P(0, 3), Q(2, 0), R(4, -3)
This implies that P, Q, and R lie on the same line.
The slope of a line is defined as; (change in y)/(change in x)
Using the points P and Q, the slope of the line is calculated as;
(0-3)/(2-0) = -3/2 = -1.5
To arrange the given polynomial in descending order of x, we only look at the exponent of x in each term and then write it in decreasing order of the value. We do as follows:
2xy^4 + 2x^2y − 3y^2 + 10x^3<span>
10x^3 + 2x^2 + 2xy^4 - 3y^2
The degree of the third term would be 5. The degree of a term is the sum of the exponents of the variables involved in the term.

Answer:
55/43
Step-by-step explanation:
(x/y) = 7/3, (x^2/y^2)=49/9, multiply by 3 above and multiply 2 below, 3x^2/2y^2=147/18. Next apply C&D and you will get (3x^2+2y^2)/(3x^2-2y^2)=(147+18)/(147-18)=165/129=55/43
Answer:
282.5 inches squared
Step-by-step explanation:
A triangle is half the area of a square.
So we will solve the area as if we were finding the area for a square, and then we halve the result.
Length multiply by height to get the area:
28.25 × 20 = 565 inches squared
Now, half the answer to get the area of the triangle:
565/2=282.5 inches squared
7/8 = x/48
Perform cross multiplication:
a/b = c/d
ad = bc
a = 7 ; b = 8 ; c = x ; d = 48
7*48 = 8x
336 = 8x
336/8 = x
42 = x
7/8 = 42/48
42 ÷ 6 = 7
48 ÷ 6 = 8
