All values increase by a scale factor of 10.
f(x)= x+10
Answer:
Function 1
Step-by-step explanation:
The y-intercept is the y-value when the x-value = 0.
In Function 1 the y-intercept is 1 because (0, 1).
In Function 2 the y-intercept is -3 because x = 0 y = -3.
And 1 > -3 so Function 1 is the answer.
Answer:
20%
Step-by-step explanation:
Use the percent change formula: difference = % * original cost
12 - 10 = 2
The difference is 2 and the original cost is 10. Now, we have the equation
2 = % * 10. We don’t know the percentage right? So now we have to find the percentage. To do this, you will have to do 2 divided by 10, which is 0.20. Lastly, we have to turn 0.20 into a percentage by multiplying it by 100, leaving you with 20%. So therefore, 20% is the percent increase. Hope this helps!
Answer:
The y-intercept is at (0,2)
Step-by-step explanation:
If you loom at the vertical line in bold on the graph, you will see that the blue line is going through the y-axis.
<u>Given</u>:
Given that the parallelogram with the lengths 5x, 3x + 1, 2y - 5 and y.
We need to determine the values of x and y.
<u>Values of x and y:</u>
We know the property that the opposite sides of a parallelogram are congruent.
Thus, we have;
------- (1)
------- (2)
The value of x and y can be determined using the substitution method.
Substituting equation (2) in equation (1), we have;
Thus, the value of x is 3.
Substituting x = 3 in equation (2), we have;
Thus, the value of y is 10.
