Arthimetic sequence so use the formula
The slope of the line = (2- -8) / (3 - - 5) = 10 / 8
= 5/4
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line so here we have:-
y - 2 = 5/4(x - 3)
y = 5/4x - 15/4 + 2
y = 5/4 x - 7/4 is the answer
Subtract the sine term and take the square root.
This load will weigh
1.5 TONS ALTOGETHER.
So, the truck is delivering a
ton of cement blocks, and a
of bricks. To find how much this load weighs, we'd have to add the two fractions together, which proves to be quite easy, because the denominators are already the same, so we wouldn't have to change anything.
+
=
And now, we would want to convert that fraction into a whole number, or at least a decimal, to find how many tons the truck is carrying. So we would divide. Once the work is done, here is what would happen:
12 ÷ 8 = 1.5
And there's your answer. The truck is carrying
1.5 TONS.
Think: You're treating the numerator and the denom. in precisely the same way. In doing so you are NOT changing the value of the fraction, only the appearance.
Example: start with 2/3. Mult num. and den. both by 7: 14/21.
2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.
