Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.
Answer: A. 1 in. : 3.6 ft.
Step-by-step explanation: In order to get the scale on the blueprint we just have to divide the measure in real time by the number of the blueprint, if we know that there´s a wall that is 21.6 feet long, and in the blue print is 6 inches long we just divide it: So now we know that for every inch in the blueprint there has to be 3.6 feet on the real construction.
Answer:
Step-by-step explanation:
<u>Let the functions be</u>
- f(x)= ax + b
- g(x) = cx + d
<u>Their sum</u>
<u>Their product</u>
<h3>The answer options</h3>
<u>A. When added, the sum of the y-intercepts must be 1.
</u>
- Correct. We see point (0,1) of j(x) on the graph. b+d = 1
<u>B. When multiplied, the product of the y-intercepts must be –15.
</u>
- Incorrect. -15 is the vertex of k(x). The vertex of ax^2 + bx + c is -b/2a. So it has no relation to constants of the functions f(x) and g(x)
<u>C. Either f(x) or g(x) has a positive rate of change and the other has a negative rate of change.
</u>
- Incorrect. It refers to the value of ac. If one of a or c has opposite sign it makes k(x) to open down but it is not as per graph.
<u>D. f(x) could have a rate of change equal to 1 and g(x) could have a rate of change of 2.
</u>
- Correct. As per above statement, both linear equations could be positive as their sum and product is positive from the graphs of j(x) and k(x)
<u>E. f(x) could have a rate of change equal to 2 and g(x) could have a rate of change of –6.</u>
- Incorrect. It should result in decreasing function of j(x) with slope of -4 but it is increasing as per graph.
Answer:
no answer, but the answer to f(x)=4(3^81)^x is
Domain-{infinity,infinity}
Range-{0,infinity}
Step-by-step explanation:
its a positive exponential formula, which has these boundaries if there isn't a change in the y axis start.
Answer:
x=2
Step-by-step explanation:
The axis of symmetry goes through the vertex and is the line that makes the image the same on one side as the other
Since this is a vertical parabola, the axis is symmetry is of the form x=
The vertex is at x=2 so the axis of symmetry is x=2
