Find two numbers whose sum is 49 and whose difference is 9?
a + b = 49 a - b = 9 Add both together to get (a+a)+(b-b) = 58 2a=58 a = 29 ◄ plug that into the second equation to get 29 - b = 9 so b = 20 ◄ Check: 29 + 20 = 49 29 - 20 = 9
Write a rule that is an example of a non-linear function when b is 49 a is 7 and a is a function of b?
Below is a rule that is an example of a non-linear function when b is 49, a is 7 and a is a function of b: a = square root of b 7 = square root 49 7=7
What is the answer to 7 b plus 15 equals -34?
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
How do you find the intercepts to the equation x2 plus y-49 equals 0?
x2 + y - 49 = 0At the x-intercepts, y=0:x2 - 49 = 0(x+7)(x-7) = 0x = -7 and x = +7At the y-intercept, x=0:y - 49 = 0y = 49General Solutionset x=0 to find your y-intercept and set y=0 to find your x-intercept. That's how you will always find your intercepts, no matter what the equation is.Ex. So if you find that when x=0, y=a, then the y-intercept is at the point (0,a).Similarly, if you find that when y=0, x=b, then the x-intercept is at the point (b,0).You can solve any problem from here.
What is the percentage when you have 8 wrong out of 49?
About 83% if rounded 84% which is a B.
