Pleaseeeeeeeeee help me

Mathematics
1 answer:
Slav-nsk [51]3 years ago
4 0

Answer:

y - 35 = 6(x - 5)

Step-by-step explanation:

The point-slope equation of a line is

y - y_1 = m(x - x_1) ,

where

m = slope = \dfrac{y_2 - y_1}{x_2 - x_1}

and the point is

(x_1, y_1)

Let's find the slope.

m = slope = \dfrac{-31 - 35}{-6 - 5}

m = \dfrac{-66}{-11}

m = 6

We are asked to use the first point in the equation, so

x_1 = 5  and y_1 = 35

The equation is:

y - 35 = 6(x - 5)

PLZ HELP ASAP SIMILARITY
PIT_PIT [208]
LY = 5.2  ,  TY = 3.9
Δ LTN is a right triangle , ∠T = 90° , TY⊥LN
∴ TY² = LY * YN
∴ 3.9² = 5.2 * YN
∴ YN = 3.9²/5.2 = 2.925

∴ LN = LY + YN = 5.2 + 2.925 = 8.125

Δ LYT is a right triangle , ∠Y = 90°
LT² = LY² + YT² = 5.2² + 3.9² = 42.25
∴ LT = √42.25 = 6.5

Δ NYT is a right triangle , ∠Y = 90°
NT² = NY² + YT² = 2.925² + 3.9² = 23.765
∴ NT = √23.765 = 4.875

The preimeter of the rectangle LINT = 2 * (LT + TN)
                                                          = 2 * ( 6.5 + 4.875 )
                                                          = 2 * 11.375
                                                          = 22.75

Can someone please help with the last problem
Brut [27]

Answer:

  18x +9h

Step-by-step explanation:

Such problems are tedious, but not difficult. The trick is to avoid making mistakes in the algebra.

  \dfrac{f(x+h)-f(x)}{h}=\dfrac{(9(x+h)^2)-(9x^2)}{h}\\\\=\dfrac{9(x^2+2xh+h^2)-9x^2}{h}=\dfrac{18xh+9h^2}{h}=\boxed{18x+9h}

It takes 36 nails to weigh one pound. How many nails would it take to weigh 7 wholes and 2/3 pounds?
o-na [289]
36 * 7  gives you the number of nails in the whole pounds
36 * 2/3 gives you the fraction part

7 * 36 = 252
2/3 * 36 = 24

Total nails = 252 + 24 = 276 nails
