63 = 9 × 7

So that means we need to multiple numerator and denominator by 7 to get the denominator to be 63.

So that would be \dfrac{7\times7}{9\times7}=\boxed{\dfrac{49}{63}}.

Hope this helps.

Solve the given system, using the substitution method.
Aleksandr-060686 [28]
Y = 3x - 7
6x - 2y = 12

6x - 2(3x-7) = 12
6x - 6x -7 = 12
-7 = 12

6x - 2y = 12
6x = 12 + 2y
x = 12/6 + 2y/6
x = 2 + y/3

y = 3x - 7
y = 3(2 + y/3) - 7
y = 6 + 3y/3 - 7
y = 6 + y - 7
y - y = 6-7
0 = -1

........ help ASAP please....
Anna11 [10]

Answer:

See below

Step-by-step explanation:

In the second step there should be (1 - cot x) instead of (1 + cot x)

(1 + tan x) [1 + cot(-x)]

= (1 + tan x) (1 - cot x)

= 1 - cot x + tan x - tan x cot x

= 1 - cot x + tan x - 1

= tan x - cot x

Given the line below.
Grace [21]

Answer:

y+2=(x+2)

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

(-2,-2) and (2,2)

substitute the values

m=\frac{2+2}{2+2}=1

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=1\\(x1,y1)=(-2,-2)

substitute

y-(-2)=(1)(x-(-2))

y+2=(x+2)
