Answer:7c +6d +12

Step-by-step explanation:3c + 7 + 12d - 6d + 4c + 5 = ?c + ?d + ?

3c + 4c +12d - 6d +7 +5

= 7c +6d +12

You combine like terms which are 3c and 4c which gives you 7c .Next you combine 12d and 6d but this time u need to subtract since it has subtact sign in between 12d and 6d which gives you 6d.After that you combine 7 and 5 which u get 12 .Lastly you put all of the tersm together which are 7c and 6d and 12 which get you 7c +6d +12 as your equivalent expression.

Find an equation of the circle that satisfies the given conditions. Endpoints of a diameter are P(−2, 1) and Q(8, 9)

IrinaK [193]

Answer:

Equation of the circle (x-3)²+(y-5)²=(6.4)²

x² -6x +9 +y² -10y +25 = 40.96

Step-by-step explanation:

Step(i):-

Given endpoints of diameter P(−2, 1) and Q(8, 9)

Centre of circle = midpoint of diameter

Centre = $(\frac{-2+8}{2} ,\frac{1+9}{2} )$

Centre (h, k) = (3 , 5)

Step(ii):-

The distance of two end points

PQ = $\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }$

$PQ= \sqrt{(8+2 )^{2} +(8 )^{2} }$

PQ = √164 = 12.8

Diameter d = 2r

radius r = d/2

Radius r = 6.4

Final answer:-

Equation of the circle

(x-h)²+(y-k)² = r²

(x-3)²+(y-5)²=(6.4)²

x² -6x +9 +y² -10y +25 = 40.96

x² -6x +y² -10y = 40.96-34

x² -6x +y² -10y -7= 0

3[5x - 4] - [-30 - 45x]

Nimfa-mama [501]

$3(5x - 4) - (-30-45x)$
$= 15x - 12 + 30 + 45x$ <- Distributive Property
$=60x + 18$ <- Combine Like Terms

If you're trying to solve for 0:

$0 = 60 x + 18$
$-18 = 60x$ <- Subtracted 18 from both sides
$x = \frac{-18}{60} = \frac{-9}{30}$ <- Divided both sides by 60 and then simplified.

$x = \frac{-9}{30}$ <- Fraction Form
$x = -0.3$ <- Decimal Form
