GEOMETRY - PLEASE HELP - WILL MARK BRAINLIEST
2 answers:
Answer:
see below
Step-by-step explanation:
1. y = mx+b where m is the slope
The first slope is -1/3
The second slope is 3
m1 = m2 means they are parallel False
m1*m2 = -1 means they are perpendicular
-1/3 *3 = -1 True
2. Squares and rhombi have all 4 sides with the same length. Squares however, have 4 angles that must equal 90 degrees. Squares are a special form of rhombi
3. To find the slope
m = (y2-y1)/(x2-x1)
= (2-11)/(-5-0)
=-9/-5
= 9/5
The distance is found by
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (-5-0)^2 + (2-11)^2)
= sqrt( 5^2 + (-9)^2)
= sqrt( 25+81)
= sqrt( 106)
Answer:
See below
Step-by-step explanation:
y = -1/3x + 2
y = 3x - 5
Slopes are -1/3 and 3, they are opposite-reciprocal, it means the lines are perpendicular
2. Difference between squares and rhombus:
The sides of a square are perpendicular to each other whereas the sides of a rhombus are not perpendicular to each other. All the angles of a square are equal whereas only the opposite angles of a square are equal. The two diagonals of a square are always equal in length while the two diagonals of a rhombus are unequal 3. points A(0,11) and B(-5,2)
Slope:
m= (y2-y1)/(x2-x1)= (2-11)/(-5-0)= -11/-5= 11/5
Distance between points:
√(x2-x1)²+(y2-y1)²= √ 25+121= √146 ≈ 12

Answer:
3
Step-by-step explanation:
y = -3x^2 + 5x <u>+ 3 </u>
↑ this is "the number at the end/constant," and according to the question the number at the end/constant is the y-intercept
Thus, the y-intercept is 3.
