Answer:
Step-by-step explanation:
Given that the line passes through two points (-1,2) and (6,3)
Slope of the line passing through (x1,y1) and (x2,y2) is y2-y1
x2-i1
Hence slope of our line =
(3-2)/(6+1) = 1/7
So in slope intercept form the equation would be
y = 1/7 x +C
to find C
Since (-1,2) lies on the line substitute these in the line equation
2 = 1/7(-1)+c
C = 2+1/7 = 15/7
Hence equation in slope intercept form is y=x/7+15/7
Answer:
infinite solutions
Distributive Property
Step-by-step explanation:
5x + 3(x − 5) = 6x + 2x − 15
Distribute
5x+3x -15 = 6x+2x -15
Combine like terms
8x -15 = 8x-15
Subtract 8x from each side
8x-8x-15 = 8x-8x-15
-15=-15
This is always true so there are infinite solutions
We used the Distributive Property
And the Subtraction Property of Equality
The answer is D. Hope this helps
The total mass was 149.5 grams.
Setting up an equation, we have that the sample size, 39.1, is 5 3/4 (5.75) grams less than 3/10 of the total mass; this gives us
39.1 = 3/10x - 5.75
Adding 5.75 to both sides, we have
44.85 = 3/10x
Multiplying both sides by 10,
448.5 = 3x
Dividing both sides by 3,
149.5 = x
