Answer:

5 square 10 yards

$40

Step-by-step explanation:

Mario:

20 + 4x

Her competitor:

10 + 6x

Where,

x = number of 10 square yards

Equate the expressions

20 + 4x = 10 + 6x

Collect like terms

20 - 10 = 6x - 4x

10 =2x

Divide both sides by 2

x = 10 / 2

= 5

x = 5 square 10 yards.

Charge at that moment

Using any of the cost equation

10 + 6x

= 10 + 6(5)

= 10 + 30

= 40

$40

Or

20 + 4x

= 20 + 4(5)

= 20 + 20

= $40

Write an equation for the line shown in the graph
koban [17]

Answer:

y= -x+10

Step-by-step explanation:

ok, so the basic formula is y=mx+b

m=slope and b= the intercept

the line crosses the y-axis at 10, so we know that 10=b. it is a downward going slope, so its negative. the formula for slope is rise/run, or in our case, fall/run. for every 2 it falls, it runs 2. that is -2/2, which can be simplified to -1. looking at the graph , it's hard to comprehend the question at first and it took me multiple times looking at the graph. I hope I helped some!
