The sum of -19ab and 7ab = -19ab + 7ab = -12ab
the sum of -11ab and -23ab = -11ab + (-23ab) = - 34ab

So
<span>Subtract the sum of -11ab and -23ab from the sum of -19ab and 7ab:

</span> (-12ab) - (-34ab) = -12ab + 34ab = 22ab

Answer
22ab

The sum of two numbers is 64 and their differences in 10. Find the numbers
uranmaximum [27]

Answer:

37 and 27

Step-by-step explanation:

Lets say that the two numbers are x and y. We get the equations x + y = 64 and x - y = 10. We can then add these two equations together to get, 2x = 74. Then we divide by two on both sides and get x = 37. We then plug this value back into the second equation and get that 37 - y = 10. We can simplify this and we get that y = 27. So our two numbers are 37 and 27.

What is the rate of change of the function y = − 1/4 x + 1
scoray [572]

Answer:

-1/4

Step-by-step explanation:

Hello!

The rate of change is also known as the slope.

Standard equation of a line: y = mx + b

  • y: output
  • m:  slope
  • x: input
  • b: y-intercept

So, if we match the standard form to the given function:

  • y = mx + b
  • y = -1/4x + 1

-1/4 is m, or the rate of change.
