The answer would be the first choice.  15 cm^{2}

Explanation: The reason for this is that the question was pretty much just asking what the area of the resulting two-dimensional cross section would be -the shape in gray- (which can be found by using the formula lw. To add on, since the dimensions of the shape are already given (5 and 3) all you've to do is multiply: 3*5=15

That's how you get to the answer.

Construct the graph of the equation y=kx if it is known that the point B belongs to the graph. The graph of which of these two e
PIT_PIT [208]

Answer:

The graph with B(2,-3) i.e) y=\frac{-3}{2} x goes through the point M(-10,15).

Step-by-step explanation:

Consider M(-10,15) and given that equation is y = kx.

Now, substitute M(-10,15) in the equation

⇒ 15 = k × -10

⇒ k = \frac{15}{-10} = \frac{-3}{2}

⇒ y = \frac{-3}{2} x

Now, check with the given points B(2,-3) and B(3\frac{1}{3} , -2)

1) B(2,-3)

y = \frac{-3}{2} x

⇒(-3) = \frac{-3}{2} × 2

⇒ -3 = -3 ⇒ LHS = RHS

⇒ B(2,-3) is the required point.

2) for b(3\frac{1}{3} , -2)

LHS ≠ RHS.

So,The graph with B(2,-3) i.e) y=\frac{-3}{2} x goes through the point M(-10,15).

The sum of two numbers is 40 and their difference is 6.5, what is their product? show work please
Finger [1]
Let b>a, 

a+b=40 so we can say a=40-b

We are told that b-a=6.5, using a found above in the equation gives us:

b-(40-b)=6.5

b-40+b=6.5

2b-40=6.5

2b=46.5

b=23.25, and since  a=40-b

a=40-23.25

a=16.75

So a=16.75 and b=23.25

check...

16.75+23.25=40, 40=40

23.25-16.75=6.5, 6.5=6.5
