pshichka [43]

Answer:

y-7 = 4(x+9)

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is the point

y-7 = 4(x--9)

y-7 = 4(x+9)

Solve for z: 4 (z+6) -11 = 25 I need to show my work

mafiozo [28]

Answer:

z=3

Step-by-step explanation:

4(z+6)-11=25

add 11 to both sides

4(z+6)-11+11=25+11

simplify

4(z+6)=36

divide each side by 4

(4(z+6))/4=36/4

Simplify

z+6=9

subtract 6 from each side

z+6-6=9-6

simplify

z=3

Multiply or divide. Show your work. 5x+10/x+2*2x/4x-10

jolli1 [7]

$\frac{5x + 10}{x + 2} * \frac{2x}{4x - 10} = \frac{5(x) + 5(2)}{x + 2} * \frac{2x}{2(x) - 2(5)} = \frac{5(x + 2)}{x + 2} * \frac{2x}{2(x - 5)} = \frac{5}{1} * \frac{x}{x - 5} = \frac{5x}{x - 5}$

Find the coordinates of the center of the following circle. (x - 3)² + (y - 7)² = 49

Zepler [3.9K]

When you write the equation of a circle in the form

$(x-x_0)^2+(y-y_0)^2=r^2$

Then the center of the circle has coordinates $(x_0, y_0)$ and the radius is $r$

So, in your case, the center of the circle is $(3,7)$
