Answer:

y=10x+75

Step-by-step explanation:

Because y-y1 = m(x-x1)

Plug in the y1(5) and x1(-7)

So, y-5 = 10(x+7)

= y=10x+75

Answer:

Step-by-step explanation:

y = -10x - 8. the slope here is -10. A parallel line will have the same slope

y = mx + b

slope(m) = -10

(-7,5)...x = -7 and y = 5

now we sub and find b, the y int

5 = -10(-7) + b

5 = 70 + b

5 - 70 = b

-65 = b

so ur equation is : y = -10x - 65 <===

Which operation will cancel out division?

emmasim [6.3K]

Answer:

The operation that will cancel out division is multiplication.

Step-by-step explanation:

For example:

$\frac{2+5x}{2} \\$

*in order to solve for x, and get the upper equation without division, you must multiply by the negative reciprocal*

$2*(\frac{2+5x}2} )$

$4+10x\\$

*to get x alone, we must subtract 4 from both sides*

$10x = -4\\\\-4 / 10 = - 2/5$

$x=- 2/5$

A circle has its center at (0,0) and passes through the point (0,9). What is the standard equation of the circle?

Alexxandr [17]

Answer:

x^2+y^2=9^2

Step-by-step explanation:

The standard equation of a circle is:

$(x-h)^2+(y-k)^2=r^2$

Where the center of a circle is (h,k) and r is the radius of the circle. In this case because a circle is equidistant from the center and we have a point where it passes through 9 that means that the radius is 9. However, since the standard equation states that we must write r in the form of $r^2$ this means that $r^2=9^2$ . Therefore by plugging in the values we have:

$(x-0)^2+(y-0)^2=9^2\\\\x^2+y^2=9^2$
