Question does not say if the straight line is the least squares best fit line. Assuming it is, we still have the question whether Wilson's score vs hours spent per week is linear, as we do see some tendance of a decline of the rate of increase at the top of the the range, which means that the function COULD be parabolic or piecewise. The score could actually decrease if Wilson has difficulty doing the homework, to a point that he spent way over the expected time to finish relatively simple homework.
To sum up, the question is incomplete in supplying necessary information, perhaps on the part of the user posting the question, perhaps the school.
Anyway, back to the question, assuming a straight line relationship according to the given straight line, rate of increase per day = (50-15)/5=7 hours/week.
Therefore if Wilson spends 6 hours to do his homework, and assuming the score follows a straight line, he expects to get 50+7=57 points, an answer that is not one of the answer choices.
Perhaps the information is incomplete, perhaps there are other possible assumptions. That's the best we can do with the question as is.

Answer:
<h3>The answer is 4.9cm</h3>
Step-by-step explanation:
To find the perpendicular distance between them that's the height we use the formula
where
a and b are the parallel sides of the trapezium
h is the perpendicular distance
From the question
Area = 31.5cm²
a = 7.5 cm
b = 5.3 cm
Substituting the values into the above formula we have
Divide both sides by 6.4
h = 4.921875
We have the final answer
<h3>h = 4.9cm</h3>
Hope this helps you

Find a point-slope form for the line that satisfies the stated conditions. Slope , passing through (-5,4)
I really need this question answered
By:
I don't see a value for the slope. We need that to set the equation, otherwise I can write an unlimited number of equations that pass through (-5,4).
I'll assume a slope so that you can see how the procedure would work. I like 6, so we'll assume a slope of 6.
The equation for a straight line has the form y = mx + b, where m is the slope and y is the y-intercept, the value of y when x = 0. We want a line that has slope 6, so:
y = 6x + b
We need to find b, so substitute the point (-5,4) that we know is on the line:
4 = 6*(-5) + b and solve for b
4 = -30 + b
b = 34
The line is y = 6x + 34
Answer:
1/2
Step-by-step explanation:
2/5 = 4/10
4/10 + 1/10 = 5/10
5/10 = 1/2
