Step-by-step explanation:

First, know that: y—y0 = m (x—x0)

y+3=2(x+1)

y = 2x —1

11)

m=∆y/∆x

m=(3—5)/(—1+2) = —2/1 = —2

y—3 = —2(x+1)

y=—2x+1

y+2=—2(x+5)

y=—2x—12

y—10=3(x)

y=3x+10

y—12=—1(x+6)

y=—x+6

m=∆y/∆x

m=(3—5)/(—1+2) = —2/1 = —2

y—3 = —2(x+1)

y=—2x+1

13)

m=(10+5)/(—6—2) = 15/—8

y+5=(15/—8)(x—2)

y=(15/—8)x — (5/4)

15)

m=(3—10)/(—3—4) = —7/—7 = 1

y—3=1(x+3)

y=x+6

Examine the diagram, where BD is tangent to circle M at point D, and BA is secant to the same circle at points E and A.

Stella [2.4K]

Answer:

19 = x

Step-by-step explanation:

The square of the tangent segment = The product of (whole secant segment) (the outside part of the secant segment)

BD²= (BA)(BE)

8² = (4 + x - 7) (4) BA = BE + EB

8² = (x - 3)(4)

64 = 4x - 12

64 + 12 = 4x

76 = 4x

19 = x

Write 3,200 in scientific notation

spin [16.1K]

Answer:

The answer is 3.2 E 3 or 3.2 x 10^3

You move back 3 spaces which is 3.2, since you moved back 3 spaces, you put 3 as the power/exponet.

To be more satisfied, 3.2 is your base number, it is the big number Below the power/exponent. The power/exponent is 3, you moved 3 spaces and you moved to the left, so it is represented as a positive power/exponent.

Hope this helps.

Look at the figure shown below

Setler79 [48]

Answer:

Answer is given below with explanations.

Step-by-step explanation:

Answer is option 1) 85 : 51

$given \: that \: \\ triangle \: SPT \: is \: similar \: to \: triangle \: QPR \\ corresponding \: sides \: of \: similar \: \\ triangles \: are \: in \: proportion \\ then \: \\ \frac{SP}{ QP} = \frac{PT }{ PR} \\ \frac{3x}{3x + 24} = \frac{51}{85} \\ taking \: reciprocal \: on \: both \: sides \\ \frac{3x + 24}{3x} = \frac{85}{51}$

Option 1 is correct.

ΔABC is a right triangle in which angle B is a right angle, AB = 1, AC = 2, and BC = square root of 3 . cos C × sin A equals wha

ad-work [718]

Remark

Study the triangle carefully. It may not be exactly as you have drawn it, but it will work if you just follow the givens.

Givens

AC = 2

AB = 1

BC = sqrt(3)

Step One

Find Cos C

Cos(C) = adjacent / Hypotenuse

Cos(C) = BC / AB

Cos(C) = sqrt(3)/2

Step Two

Find Sin(A)

Sin(A) = opposite / hypotenuse

Sin(A) = AB / AC

Sin(A) = 1/2

Step Three

Find Cos(C) * Sin(A)

Cos(C) * Sin(A) = sqrt(3)/2 * 1/2 = sqrt(3) / 4 <<<< Answer
