Answer:
x = -2.585
Step-by-step explanation:
You will have to plug this into your graphing calculator.
In y=, type 5(1/2)^x in the Y1 and type 30 in Y2.
When you hit 2nd trace and hit find intersections, you will get (-2.585, 30).
The answer is x = -2.585
Answer:
You're trying to buy a video game that costs $40 with a $50 bill. The cashier gives you $10 change, which is the remainder.
Step-by-step explanation:
Answer:
Slope = 4/3x; y-intercept = -1
Step-by-step explanation:
y + 1 = 4/3x
You have to write this equation in slope-intercept form (solve for y) if you want to find the slope and y-intercept
y + 1 = 4/3x
Subtract one from both sides
y + 1 - 1 = 4/3x - 1
y = 4/3x - 1
Now that we have the equation, you can now find the slope and y-intercept
y = mx + b; m is the slope and b is the y-intercept
So for y = 4/3x - 1, the slope is 4/3x and the y-intercept is -1
Answer:
y = 3x + 3
Step-by-step explanation:
The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept of the line. I will calculate the slope using the points (0, 3) and (1,6)
Slope =
= 
= 3
The y-intercept, based on the graph, is 3. Thus, the equation is: y = 3x + 3.
