Solve for r in terms of s, t, and u. <br> t=u-s+r

Verdich [7]

Answer:

r = t - u - s

Step-by-step explanation:

To solve for r in terms of s, t, and u, means to have r on one side and have t, u, and s.

t = u - s + r

t - u = s + r

t - u - s = r

Write the equation in standard form of a circle with center (-7,2), tangent to the y-axis.

Vesna [10]

Answer:

$(x+7)^2+(y-2)^2=7^2$

Step-by-step explanation:

Tangent to y-axis means that the side of the circle TOUCHES the y axis.

Since the center is at (-7,2) and it touches the y axis, we can figure out the radius. It goes from (-7,2) to y-axis. Horizontally, the center is 7 units left of y-axis, so that is the radius ----- 7 units

The standard form of a circle is:

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

Where

(h,k) is the center

r is the radius

Putting the information into the form, we have:

$(x-h)^2+(y-k)^2=r^2\\(x-(-7))^2+(y-(2))^2=7^2\\(x+7)^2+(y-2)^2=7^2$

THis is the standard form.

Jesse Stroh the coin in her bank she made 7 stacks of 6 diamonds and 8 stacks of 5 nickels she then found one diamond and 1 nick

fiasKO [112]

So there are 8 stacks of 5 nickels which means that the equation would be simply 8 * 5 which equals 40 nickels. Then, 7 stacks of 6 dies would equal 42. Then she found one more dime and one more nickel which means she has 41 nickels and 43 dimes. In all, she has 84 dimes and nickels.
