Answer:

a) x = 13

b) x = 7

Step-by-step explanation:

A) Since they have the same base of 2 so

x + 4 + (-5) = 12

x - 1 = 12

x = 13

b) Since they have the same base of -3 so

8 + x + 4 = 19

x + 12 = 19

x = 7

The radius, r, of a circle is one-half of the length of its diameter, d. r= r= d + r = d 2 r = d r = d

PIT_PIT [208]

If the radius is HALF of the diameter, then the expression would be 1/2r=d or d/2=r.

hope it helps!

The following system has a solution: x=10, y=-3, z=14

wolverine [178]

<h2>Answer:</h2><h3>False</h3>

<h2>Step-by-step explanation:</h2>

In this problem, we have the following System of Three Equations in Three Variables, so our goal is to determine whether $x=10, \ y=-3, \ z=14$ is the solution to this system, that is, the ordered triple $P(x,y,z)$ where three planes intersect.

The easier way to find the answer is to plug in the x, y and z values in the equations and figure out whether the equations satisfy the solutions. Then:

$First \ Equation: \\ \\ 3(10)+7(-3)-14=-5 \\ \\ It \ satisfies \ the \ first \ equation \\ \\ \\ Second \ Equation: \\ \\ 9(10)-(-3)-4(14)=37 \neq 17 \\ \\ It \ doesn't \ satisfy \ the \ second \ equation$
