How do you solve 8a squared plus 2 = 634

Inga [223]

Answer:

a ≈ 8.9

Step-by-step explanation:

Set up the equation as so:

8a^2 + 2 = 634

First, subtract two from both sides:

8a^2 = 632

Then, divide by 8 to further isolate the variable.

a^2 = 79

To get rid of the squared, you have to take the square root of both sides. The square root of 79 is roughly 8.9. Ergo, a ≈ 8.9

What is mZDAR in circle A?

Andreas93 [3]

Answer:

68°

Step-by-step explanation:

Since, angle subtended on the circumference of the circle is half angle subtended on the center of the circle.

$\therefore m\angle DBR = \frac{1}{2} \times m\angle DAR\\\\\therefore 34\degree = \frac{1}{2} \times m\angle DAR\\\\\therefore 34\degree \times 2= m\angle DAR\\\\\therefore 68\degree = m\angle DAR\\\\\therefore m\angle DAR=68\degree$

Given that 3x + y = 0 and 2x - y = 5, find the value of y.

professor190 [17]

Answer:

3x + y = 0

x = -y/3

Now, 

2x - y = 5

2 (-y/3) - y = 5

(-2y - 3y)/3 = 5

-5y/3 =5

y=-3
