Step-by-step explanation:
Let the number be x. Then x + 10 = 20.
This is all you need to write out. But, for practice, find the solution as well.
The solution for the #23 equation is either x=9 or x= -3
Answer:
The answer is C
Step-by-step explanation:
You always want to get y by itself and in the form y = mx + b. So first, subtract 4x from both sides to get -y = -4x +32
You also want to get rid of that negative sign. That’s easy, divide everything by negative 1 to get:
y = 4x - 32
We can see the slope is just 4 and the y intercept is -32. The y-intercept is when x equals zero, you’ll get -32 if you do so. The x-intercept is now when y equals zero. Now solve for x. You get 4x = 32, divide by 4 to get 8
a.) 8
b.) -32
c.) 4
