Match the coordinates with the points on the coordinate plane

Mathematics
1 answer:
Gnesinka [82]3 years ago
5 0

Answer:

Step-by-step explanation:

(-2\frac{1}{2},3\frac{1}{2})

Since, x-coordinate is negative and y-coordinate is positive, point will lie in the 2nd quadrant.

Answer is point P.

(-3, 6)

Point L represents the given coordinates.

(-4\frac{1}{2},2)

Point P represents the given coordinates.

(2\frac{1}{2},2\frac{1}{2})

Since, x and y coordinates are positive, point will lie in the 1st quadrant.

Point Q represents the given coordinates.

(-1\frac{1}{2},-3\frac{1}{2})

Since, both x and y coordinates are negative, point will lie in the 3rd coordinate.

Point R represents the given coordinates.

Answer:

the three boxes should be filled with

2 8 -12  

respectively

Step-by-step explanation:

The general equation of the parabola in this problem is

y = a(x-h)^2 + k

vertex is at (-2, -20), => k=-20, h = 2

so the equation is

y = a(x+2)^2 - 20

To have y-intercept = -12, we set x = 0

-12 = a(0+2)^2 - 20

a(2^2) = 8

a = 2

therefore the equation of the parabola is

y = 2 (x+2)^2 -20 = 2x^2 + 8x - 12

the three boxes should be filled with

2 8 -12  

respectively

Kenneth solved a certain number of problems and Harold solved 2 more than twice as many. Together they
Inessa [10]

H(arold) = 2 + 2*K(enneth)

H = 2 + 2K

H + K = 38

Substitution:

2 + 2K + K = 38

3K = 36

K = 12

Kenneth solved 12 problems and Harold solved (2(12) + 2 = 24 + 2 =) 26 problems

a bowler knocks down at least 6 pins 70% of the time. Out of 200 rolls, how many times can you predict the bowler will not down
Naddik [55]
Since he knocks at least 6 pins 70% of the time.

For 200 rolls:

70% of 200

= (70/100) * 200

= (7/10) * 200

= 140

140 times. 

hope this helps :)
