The area of a trapezoid is the height times the average of the two bases, mathematically:

A=h(b1+b2)/2, in this case h=6in, b1=9in, and b2=7in so

A=6(9+7)/2

A=6*16/2

A=48in^2

Explain how you can use multiplication to find the quotient 3/5 divided by 3/15. Then evaluate the expression

sveta [45]

when you divide 2 fractions, you reverse the second fraction then use multiplication

3/5 divided by 3/15 becomes

3/5 x 15/3 = 45/15 = 3

Graph by using the slope and the y intercept.

Mashutka [201]

1. a) equation of the line :

$y = \dfrac{2}{5}x - 7$

y - intercept = -7

so, it will pass through point (0, -7)

and if we plug the value of x as 5, we get

$y = (\dfrac{2}{5} \times 5) - 7$

$y = 2 - 7$

$= - 5$

so, it will pass through point (5, -5) too

now, just plot the points (0 , -7) and (5 , -5) and join them.

2. b) equation of line is :

$y = - 3x + 5$

here, y - intercept = 5

so the line passes through point (0 , 5)

now, Plugging the value of x = 1 we get :

$y =( - 3 \times 1) + 5$

$y = - 3 + 5$

$y = 2$

so, the given line passes through point (1 , 2)

plotting the points, we can get our required line.
