Answer: Equation of st line is Y= -9X + 141
Step-by-step explanation: Given Y= 24 when X = 13 and Y = 87 when X = 6
Let the equation be Y = mX + C
24 = m*13 +C
and 87 = m* 6 +C
Give m = -9 and C = 141
Equation of st line is Y= -9X + 141
In Pattern 1, they all contain the blue points. In Pattern 2, they all seem to share a center point. I'm not sure about Challenge 1 though.
<span>10x+y=19
when x = 10:
substitute with x=10 into the equation given:
10(10) + y = 19
or:
100 + y = 19
bring 100 to the other side to be -100
y = 19 - 100
y = -81
That's it

Answer: 8
Step-by-step explanation
Write as a decimal
7 11/18 is equal to 7.6111
Round the decimal to the nearest whole number:
If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.
If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.
Since 6 is in the tenths place we round up. 7 11/18 can be written as 8 (as whole number)
