Rearrange to vertex form:-
y = x^2 - 2x - 7
y = (x - 1)^2 - 1 - 7
y = (x - 1)^2 - 8
The vertex is at the coordinates (1, -8)
Answer:
50%.
Step-by-step explanation:
Given that a math class contains 40 students, and there are 18 females (two of whom speak Spanish) and 22 males (two of whom speak Spanish), in order to know the percent of Spanish speaking students that are male with respect to the total Spanish-speaking students, the following calculation has to be made:
2 + 2 = 4
2 / 4 = 0.5
Therefore, the percentage of Spanish speaking students that are male is 50%.
Answer: -4
Step-by-step explanation:
