In this question, it is given that y varies inversely as x . So the equation is

y = \frac{k}{x}

And here k is the proportionality constant .

And when x=6, y=12

12 = \frac{k}{6}
\\
k =72

So the values of the proportionality constant k is 72 and the correct option is B.

Find the area of a trapezoid , given the bases b1 = 14 mi and b2 = 25 mi and hight h= 6 mi​
elena55 [62]

Answer:

area = 117

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = \frac{1}{2} h (b₁ + b₂ )

here h = 6, b₁ = 14 and b₂ = 25

A = \frac{1}{2} × 6 × (14 + 25) = 3 × 39 = 117

Could someone explain this to me
Bond [772]

Answer:

Step-by-step explanation:

The question is asking you to graph the equations.

The equations are in slope intercept form so y=mx+b

M is the slope and b is the y-intercept

First draw the y & x axis and label/number them

The y-intercept for the first equation is -1 so draw a dot on the -1 on the y-axis

The slope is 2/5 and you use rise/run to continue the slope.

you rise 2 on the y-axis and go right 5 times on the x-axis (for a negative number you go left/down)

For the second equation, you have to turn it into slope intercept form.

You should get y=2/3x+3

You graph this equation the same as you did the first one.
