Answer:
(3, 50) and (14,303)
Step-by-step explanation:
Given the system of equations;
y=23x–19 ....1
x²–y= – 6x–23 ...2
Substitute 1 into 2;
x²–(23x-19)= – 6x–23
x²–23x+19= – 6x–23 .
x²-23x + 6x + 19 + 23 = 0
x² - 17x + 42 = 0
Factorize;
x² - 14x - 3x + 42 = 0
x(x-14)-3(x-14) = 0
(x-3)(x-14) = 0
x = 3 and 14
If x = 3
y = 23(3) - 19
y = 69-19
y = 50
If x = 14
y = 23(14) - 19
y = 322-19
y = 303
Hence the coordinate solutions are (3, 50) and (14,303)
Answer:
Mean = 24
Variance = 107.78
Standard deviation = 10.38

Answer:
2/8
Step-by-step explanation:
Tamila traveled 5/8 of the distance to her grandmother house on Saturday
They traveled 1/3 of the remaining distance on Sunday
Therefore the total distance traveled to her grandmother's house on Sunday can be calculated as follows
5+1
= 6
8-6
= 2
2/8
Hence the distance travelled is 2/8
