5x + 3 = 3x + 11
• first put all the x-values on one side and the rest on the other
Remember: when the number moves to the other side of the equal sign the sign (+ OR - switches. For ex: the 3 on the left becomes negative when moved to the right side of the equal sign)
5x - 3x = 11 - 3
• subtract left and right sides separately
2x = 8
• divide both sides by 2 to solve for x
2x/2 = 8/2
x = 4 (final answer)
#6 80, 162.5
#7 .375, .4 repeating
Answer:
slope = (1 -(-3)) / (1-0) = 4/1 = 4
Step-by-step explanation:
the function is linear, so the rate of change is constant. Another word for rate of change is slope. The slope of the line is 4.
y = mx + b (m is the slope; b is the y-intercept)We can do the math if your teacher wants.
f(x) = 4x -3
f(1) = 4 -3 = 1
f(0) = 0 -3 = -3
slope = (1 -(-3)) / (1-0) = 4/1 = 4
hope this helped :) <3
Since she flipped the coin 20 times and got 4 heads and 6 tails, you put it as a fraction. So, it's 4/16 if you simplify 4 over 16 you get 1/4. You get this by dividing by 4 both numbers.
Answer:
A. 1
Step-by-step explanation:
I see only one red function line in the graph. this line represents the simple function y = 1, for x in the interval [-2,1].
the domain of a function defines the possible values for x, and the range of a function defined the possible values for y.
this function has only one possible value for y : 1
so, only A applies.
