Answer:
Hey there!
There are 3+4+6+3, or 16 females.
3 of the females are seniors.
Thus, the percent is 3/16, or 19%
Let me know if this helps :)
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.
since by the provided tickmarks WE ≅ ER, and QE ≅ ET, then both triangles are congruent by LL theorem, Leg Leg.
anyhow, since those legs are congruent, their hypotenuses must also be congruents, and we could use the HL theorem as well.
