Write the standard equation of a circle that passes through (-5 5) with center (-10 -5) brainly

timama [110]

Answer:

The equation of the circle is (x + 10)² + (y + 5)² = 125 in standard form

Step-by-step explanation:

* lets study the standard form of the equation of a circle

- If the coordinates of the center of the circle are(h , k) and its radius

is r, then the standard equation of the circle is:

(x - h)² + (y - k)² = r²

* Now lets solve the problem

∵ The coordinates of the center of the circle are (-10 , -5)

∵ The standard form of the equation is (x - h)² + (y - k)² = r²

∵ h , k are the coordinates of the center

∴ h = -10 , k = -5

∴ The equation of the circle = (x - -10)² + (y - -5)² = r²

∴ The equation of the circle = (x + 10)² + (y + 5)² = r²

- To find the value of the radius lets use the point (-5 , 5) to

substitute their coordinate instead of x and y in the equation

∵ The circle passes through point (-5 , 5)

∵ (x + 10)² + (y + 5)² = r²

- Use x = -5 and y = 5

∴ (-5 + 10)² + (5 + 5)² = r² ⇒ simplify

∴ (5)² + (10)² = r²

∴ 25 + 100 = r²

∴ r² = 125

* Now lets write the equation in standard form

∴ (x + 10)² + (y + 5)² = 125

* The equation of the circle is (x + 10)² + (y + 5)² = 125 in standard form

I need help, help me plz !!!!! Match the verbal expression (term) with its algebraic expression (definition). Match Term Definit

Talja [164]

Answer:

Four less than an unknown value E) $y-4$

Quotient of a variable and four B) $\frac{z}{4}$

Some number to the power of four A) $a^4$

Four times an unknown value D) $4x$

Four more than some number C) $b+4$

Step-by-step explanation:

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling $y$ the unknown value, it means we have to write

$y-4$

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling $z$ the unknown variabl, it means we have to write

$\frac{z}{4}$

- Some number to the power of four --> this means that we have to write the power of a number, in the form $a^m$ , where m in this case is equal to 4. Calling $a$ the unknown number, it means we have to write

$a^4$

- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling $x$ our unknown values, we have to write

$4x$

- Four more than some number --> this means we have to add 4 to an unknown number. Calling $b$ the unknown number, it means we have to write

$b+4$
