To prove HL you need to prove that the same leg of both of the triangles are congruent and the hypotenuse, and they must be right triangles.

HL- I'd the hypotenuse an a led if a right triangle are congruent to the hypotenuse and a led if another right triangle, then the triangles are congruent.

For SAS, the two sides and the included angle of one triangle are congruent to two sides and the included angle if anther triangle, then the two triangles are congruent.
So you basically need to prove that a side, angle, and a side are congruent......

I really hope that this made sense.....tell me if not.

Answer:

a) y = 7 - x

b) m = 24 ÷ d

c) p = 10w + 7

d) y = 3x - 5

e) b = a^2 + 7

f) p = 50 - 8n

Step-by-step explanation:

a) x - values are 4, 5, 6, 7

    y- values are 3, 2, 1, 0

y = 7 - x


b) d values are : 1, 2, 3, 4

   m values are : 24, 12, 8, 6

m = 24 ÷ d

c) w values are : 0, 1, 2, 3

p value are : 7, 17, 27, 37

p = 10w + 7

d) x values are : 0, 1, 2, 3

y values are: -5, -2, 1, 4

y = 3x - 5

e) a values are : -4, -3, -2, -1

b value are : 23, 16, 11, 8

b = a^2 + 7

f) n values are : 0, 1, 2, 3

p values are : 50, 42, 34, 26

p = 50 - 8n

Thank you.

Answer:

Dave and Anna:

1. Income highlight:

combined take home pay of $900/week

Total income: 4(900) - because 4 weeks in most months = $3600

-----------------------------

2. Expense highlights:

bi-weekly mortgage of $675

property taxes of $1800

Car expenses $160

Car insurance: $128

House insurance: $35

Saving for kids: $200

-------------

Expense calculations:

Mortgage bi-weekly = 675 x 2 = $1350/month

Property taxes = 1800/12 months/year = 150/month

everything else is already monthly

1350 + 150 + 160 + 128 + 35 + 200 = 2,023

---------------------------------------

income - expenses

$3600 - 2023 = $1,577 surplus

-----------------------------------------------------------------------------

Jacob:

Income highlights:

Canada Pension Plan $848/month

Old Age Security: $484/month

Total income: $1332

--------------------------

Expense highlights:

property tax: $3000/yr = $250/month

burial expenses: $100/month (for 6 more months)

golfing: $500/year = $41.67/month

bowling: $100/year = $8.33/month

Total expenses: 250 + 100 + 41.67 + 8.33 = 400

-----------------------------

Income - expenses:

1332 - 400 = $932 surplus

A particular style of sunglasses costs the retailer $70 $⁢70 per pair. At what price should the retailer mark them so he can sel
Alexxx [7]

After the 10% discount on marked price (P), the selling price is ...

... P×(100% -10%) = 0.90P

After a markup off 35% on cost, the value is

... $70×(100% +35%) = 1.35×$70 = $94.50

The retailer wants these two values to be equal:

... 0.90P = $94.50

... P = $94.50/0.90 = $105.00 . . . . . divide by the coefficient of P

The marked price should be $105.00.
