Solve (x + 9)2 = 25.
Rina8888 [55]

Answer:

x = -4 and x = -14

Step-by-step explanation:

Our equation is (x + 9)² = 25

Applying the square root property we would need to take the square root of both sides: \sqrt{(x+9)^{2} } =\sqrt{25}

This give us x + 9 = ±5

Here we have two equations since taking the square root gives us a positive and negative value

Our first equation is x + 9 = 5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -4

Our second equation is x + 9 = -5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -14

NEED HELP QUICK!!
mrs_skeptik [129]

Answer:

(x - 2)² + (y - 6)² = 49

Step-by-step explanation:

Equation of a circle formula:  (x - a)² + (y - b)² = r²

where (a, b) is the center of the circle and r is the radius

Given, center = (2, 6) and radius = 7

Substitute this information in the equation of a circle formula.

⇒ Equation of the circle:  (x - 2)² + (y - 6)² = 49

8x-5y= 14<br> – 5х+бу = -3
podryga [215]

Answer:

y= 34/23

x=  123/46

Step-by-step explanation:

Solve for x

8x-5y= 14

x= 14/8 +5/8y

Sub x into second equation

– 5х+бу = -3

-5(14/8 +5/8y) + 6y= -3

-29/4 +23/8y = -3

y= 34/23

Sub y into any equation and solve for x

8x=483/23

x= 123/46
