Pretend these are coordinates that you can use to find the slope of the line.
(10, 40) and (15, 60). Fit these into the slope formula to find the slope of the line you are looking for:
and the slope is 4. Now use one of the points and the slope of 4 to solve for b, the y-intercept:
40 = 4(10) + b so b = 0. The equation of the line then is y = 4x + 0 or just
y = 4x

Answer:
1680 ways
Step-by-step explanation:
In this question, we are tasked with finding the number of ways in which we can select 4 trips out of 8 to make today.
Let us label the the trips we are to select as A B C D, one after the other
For selection A, we have 8 different trips waiting to be selected
For selection B, we have 7 trips to select from
For C, we have 6 to select from
while for D, we have 5 to select from. Thus, the total number of ways in which we can select these trips can be calculated as = 8 × 7× 6× 5 = 1,680 ways

Answer:
a) 230
b) 300
c) 2×10^-2
d) 1.1×10^-6
Step-by-step explanation:
a) 0.26 × 890 ≈ 1/4 × 900 ≈ 225 ≈ 230
b) 1.95/(.67×10^-2) ≈ 2/(2/3)×10^2 ≈ 300
c) 2010×10^-5 ≈ 2×10^3×10^-5 = 2×10^-2
d) 9.98×10^-4/(9×10^2) = 9.98/9×10^(-4-2) ≈ 1.1×10^-6

YMMV depending on how you do the rounding and approximate multiplication and division.
The first one can be done multiple ways. For most accurate results, increasing one number while decreasing the other is recommended. (You don't want to compute 0.3×900, for example.)
Answer:
-14
Step-by-step explanation:
forget the parenthesis. just think of it as -6-8, for instance on a number line, if you start on -6 and you SUBTRACT 8, then youre going left, so youd be going further into the negative numbers. you can also think of it as 6+8, which would be 14, then slapping the negative sign back on it.
