Answer:
D
Step-by-step explanation:
A) Incorrect. x = 4 means that all points on the line must have x coordinate equal to 4. Neither points satisfy this.
B) Incorrect. We can rewrite the equation to be y=x/4. If we calculate the slope between the two points we get a slope of 0, not 1/4.
C) Incorrect. If y = 3, all points must have y coordinate equal to 3. Neither points satisfy this.
D) Correct. If y = 4, all points must have y coordinate equal to 4. Both points satisfy this.
The length of each side of the tiles is 7.2 in
<u>Explanation:</u>
Given:
Height of the tile, h = 3 in
Area of each tile, A = 21.6 in²
Length of each side, a = ?
We know:
A rhombus is a type of quadrilateral whose opposite sides are parallel and equal.Also, the opposite angles of a rhombus are equal and the diagonal intersect each other perpendicularly.
To find the area of a rhombus when the measures of its height and side length are given, use the formula
A = Base X height
21.6 in² = a X 3 in
a = 7.2 in
Therefore, the length of each side of the tiles is 7.2 in
The answer is k is greater than or equal to 18
The expression represents a straight line equation of the form y=mx+c. where m is the slope and c is the y-intercept. From the given expression,
m=1.10 and c=0
therefore since a(w)=1.10w+0 is a straight line equation, the domain of the equation will be:
(-∞,∞)
and the range will be:
(-∞,∞)
This is because the domain and range of the straight line is always (-∞,∞).
Carlos factored incorrectly because he didn't simplify the trinomial like Sophie did. They both will have the same answer, but Carlos needs to simplify before factoring.
