Answer:
(a) $3800
(b) (a) -- April to May
Step-by-step explanation:
<h3>(a)</h3>
The least amount is found at the lowest point on the graph. That point is in May. It is on the line between 3700 and 3900, so the amount is $3800.
The least donation amount is a month is $3800.
__
<h3>(b)</h3>
The greatest month-to-month decrease is found where the line on the graph has the steepest negative slope. There are two segments with negative slope:
- April - May (decrease of $500)
- June - July (decrease of $100)
The decrease from April to May is by far the largest of these two decreases.
The greatest decrease occurred April to May.

<u>Equation of a line</u>
The general equation of a line can be written as:
Ax+By=C
The x-intercept is the point where the line crosses the x-axis, i.e. y=0, thus replacing x=3 and y=0:
A(3)+B(0)=C
3A=C
Solving for A:
A=C/3
The y-intercept is the point where the line crosses the y-axis, i.e. x=0, thus replacing x=0 and y=5:
A(0)+B(5)=C
5B=C
Solving for B:
B=C/5
Replacing into the general equation:
Simplifying by C:
The point P(k,10) belongs to the line, thus:
Operating:
Multiplying by 3:
Answer:
The answer is D.
Step-by-step explanation:
Using Pythogaras' Theorem to find the value of x. The formula is, hypo.² = side² + side² :
side = 8 units
side = 12 ÷ 2
= 6 units
hypo.² = 8² + 6²
= 100
hypo. = √100
= 10
Answer:
none of them (-9 - 4 would work if it were an option)
Step-by-step explanation:
