Which point lies inside the circle with equation (x − 2)2 + (y + 3)2 = 4? a(0, −3) b (2, 0) c (2, −5) d(2, −4)

Stolb23 [73]

Answer:

d. (2, -4)

Step-by-step explanation:

The equation describes a circle centered at (2, -3) with a radius of 2.

Any points with an x-coordinate of 2 must have a y-coordinate in the interval -3±2 = (-1, -5) to be inside the circle. One such point is ...

(2, -4) . . . . choice D

Plz help me with this sum, see the pic. Thank you

lozanna [386]

Answer:

${5}^{8} {x}^{6}$

Step-by-step explanation:

$\bigg( \frac{125 {x}^{ - 3} }{ {5}^{ - 3} \times 25 \times {x}^{ - 6} } \bigg)^{2} \\ \\ = \bigg( \frac{ {5}^{3} {x}^{ - 3} }{ {5}^{ - 3} \times {5}^{2} \times {x}^{ - 6} } \bigg)^{2} \\ \\ = {( {5}^{3 + 3 - 2} {x}^{ - 3 + 6} })^{2} \\ = {( {5}^{6 - 2} {x}^{3} )}^{2} \\ = {( {5}^{4} {x}^{3}) }^{2} \\ = {5}^{4 \times 2} {x}^{3 \times 2} \\ = {5}^{8} {x}^{6} \\$

Factor each completely. <br><br>10a² - 9a + 2 <br><br>

Sophie [7]

Answer:

a= $\frac{2}{5}$ or $\frac{1}{2}$

Step-by-step explanation:

Equate the equation to zero

$10a^{2}$ -9a+2=0

$10a^{2}$ -5a-4a+2=0

5a(2a-1)-2(2a-1)=0

Write out the factors

(5a-2)(2a-1)=0

Then equate each factor to zero

5a-2=0 OR 2a-1=0

5a=2 OR 2a=1

a= $\frac{2}{5}$ OR a= $\frac{1}{2}$

a= $\frac{2}{5}$ or $\frac{1}{2}$

What is the solution to the following equation?

MrRa [10]

I believe the answer is 3.
If you would like me to show my work please reply saying so.
Sorry if I'm wrong, but I hope this helps.

4(3x - 6) +15 = 27
Distributive Property
12x + -24 + 15 = 27
Add the two constants (numbers without variables)
12x + -9 = 27
Because 9 is negative, add 9 to both sides.
12x = 36
Divide both sides by the coefficient (number with x)
x = 3
