Answer:
3 - B
4 - D
Step-by-step explanation:
Hey There!
they are asking for the slope in slope intercept form
y = mx + b
where m = slope and b = y intercept
The slope is change in y over change in x
as y goes up 4 x goes up 2
4/2=2 so the slope (or m ) is 2
The y intercept is at point (0,-4)
So the y intercept (or b) is -4
now we add everything together and get that the equation of the line is
y=2x-4
for 4
the best rule is D 2n+2
Why? because the rate of change is 2
and the y intercept is at (0,2) so the best rule would be 2n+2
Answer:
76
Step-by-step explanation:
PQRS is a Rhombus.
Property of Rhombus : -
All sides are equal.
So,
PQ = QR = RN = NP
RN = 5x + 16
QR = 9x - 32
QR = RN
5x + 16 = 9x - 32
9x - 32 = 5x + 16
9x - 5x = 16 + 32
4x = 48
x = 48 / 4
x = 12
Substitute x = 12 in RN,
RN = 5x + 16
= 5 ( 12 ) + 16
= 60 + 16
RN = 76
Since,
PQ = QR = RN = NP
Therefore,
PQ = 76
Answer:
D
Step-by-step explanation:
On the graph, the first action you see is a straight line going up. The key word you look for in the word explanations are "increase" and "constant rate". Then, the 2nd action you see is a straight line not going up or down, just staying on the same level. This could be called "remaining the same" or stopping/resting. Then, you see a straight line going down. You look for "decrease" at a "constant rate." D matches all of those.
Answer:
B
Step-by-step explanation:
- y = 7 , that is y = - 7
Is a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of - 7
