Lila wrote an equation of the cost for printing brochures, where x represents the number of brochures and y represents the total

cost. The total cost for 35 brochures is $41.45. The total cost for 65 brochures is $55.55.
Step 1: Write the ordered pairs mc017-1.jpg and mc017-2.jpg.

Step 2: Find the slope. mc017-3.jpg

Step 3: Find the y-intercept to write the equation in slope intercept form. mc017-4.jpg

Which explains the error that Lila made?
Lila made in error in Step 1 by reversing the ordered pairs.
Lila made an error in Step 2 by not using the slope formula.
Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair.

How much greater is the weight of the large box at 3/4lb than the small box at <br> 1 1/8lbs
spin [16.1K]
Well, is just their difference, let's first convert the mixed fraction to "improper" and then subtract.

\bf \stackrel{mixed}{1\frac{1}{8}}\implies \cfrac{1\cdot 8+1}{8}\implies \stackrel{improper}{\cfrac{9}{8}}\\\\&#10;-------------------------------\\\\&#10;\cfrac{9}{8}-\cfrac{3}{4}\impliedby \textit{our LCD is then 8}\implies \cfrac{(1\cdot 9)~~-~~(2\cdot 3)}{8}&#10;\\\\\\&#10;\cfrac{9-6}{8}\implies \cfrac{3}{8}

PLZ HELP!!!<br> I will give you brainliest
Artist 52 [7]

Answer:

141

Step-by-step explanation:

CD = | 4-(-2)| = 6

DB = |3-(-7)| = 10

area of a right triangle

A = (leg 1 x leg2)/2 = (6 x 10)/2 = 30

EB = |3-(-3)| = 6

EF = |-8-(-2)| = 6

area of a square = side^2

A = 6^2 = 36

segment G(and a point with same x coordinate of H)

|8-3| = 5

segment H(and the same point)

|-10-(-8)| = 2

A = (5x2)/2 = 5

segment I(and the same point)

|-8-6| = 14

Area of a rectangle

A = base x width

A = (5 x 14) = 70

total area = 70 + 5 + 36 + 30 = 141
