wants to compare the english skills of girls and boys in the sixth grade. She administers a series of english problems to both the groups and asks them to solve as many problems as they can within a 20-minute time period. She finds that both the groups were able to answer only 15% of the problems. The results are most likely due to a effect.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

answer: graphs are something you write or draw and equations are math problems

x > 4

step-by-step explanation:

solve for   x by simplifying both sides of the equation, then isolating the variable.
