Answer:
-3 and -2
Step-by-step explanation:
7x² + 19x + 21 = 4x² + 4x + 3
combine like terms:
3x² + 15x + 18 = 0
3(x² + 5x + 6) = 0
(x + 3)(x + 2) = 0
x = -3
x = -2
Step-by-step explanation:
y = 2x + 3
When x = 2
y = 2.2 + 3
y = 4 + 3
y = 7
When x = 0
y = 2.0 + 3
y = 0 + 3
y = 3
When x = -2
y = 2.(-2) + 3
y = -4 + 3
y = -1
When x = -4
y = 2.(-4) + 3
y = -8 + 3
y = -5
When x = -7
y = 2.(-7) + 3
y = -14 + 3
y = -9
Step-by-step explanation:
draw a horizontal line from the vertical axis where 1.5 ft is, which indicates the length in feet then if it touches the line of the graph, then from the point, it touches the line Trace it down to the horizontal axis. and get the answer. the point where it touches the horizontal axis indicates the length in inches.
Answer:
d(P,Q) = 5.83 units
Mid-point = (23.5,25.5)
Step-by-step explanation:
Given points are:
P(21,24) = (x1,y1)
Q(26,27) = (x2,y2)
The distance formula is given by:
Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point.
Putting the given values in the formula
Rounding off: 5.83 units
The mid-point of two points is given by the formula:
Putting the values:
Hence,
d(P,Q) = 5.83 units
Mid-point = (23.5,25.5)
Answer:
4:50
Step-by-step explanation:
The clock shows 4:40
It takes 10 minutes to get home, so add 10 minutes to 4:40 and you will get 4:50.
