3 x 3 = 9
81 + 9 = 90
square root of 90 = 9.5

Answer:

The equation of the circle is given by:

(x-a)^2+(y-b)^2=r^2

where:

(a,b) is the center of the circle

given that the center of our circle is (2,3) with the radius of 5, the equation will be:

(x+2)^2+(y+3)^2=5^2

expanding the above we get:

x^2+4x+4+y^2+6y+9=25

this can be simplified to be:

x^2+4x+y^2+6y=25-13

x^2+y^2+4x+6y=12

Solve the inequality -5/4(8x+4)<6-3x. Show your work.

Debora [2.8K]

Answer:

$x>-\frac{11}{7}$

Step-by-step explanation:

Step 1: Distribute

$-\frac{5}{4} (8x+4)$

$(-\frac{5}{4} *8x)+(-\frac{5}{4} *4)$

$-\frac{40x}{4}-\frac{20}{4}$

$-10x-5$

Step 2: Add 10x to both sides

$-10x-5\mathbf{+10x}$

$-5$

Step 3: Subtract 6 from both sides

$-5\mathbf{-6}$

$-11$

Step 4: Divide both sides by 7

$-11\mathbf{/7}$

$x>-\frac{11}{7}$

Answer: $x>-\frac{11}{7}$

Y varies directly with x. If y=25 when x=5, find y when x =-4 y =

alina1380 [7]

Answer:

y = -20

Step-by-step explanation:

Given that y varies directly with x it means changing x will also cause change in y

Mathematically it can be written as:

y∝x

Removing the proportionality symbol

y = kx

Given y=25 when x=5 Putting the values

$25 = k(5)\\k = \frac{25}{5}\\k = 5$

Now

$y = 5x$

We have to find the value of y when x = -4

Putting x=-4

$y = 5(-4)\\y = -20$

Hence,,

y = -20
