A class of 28 students had a mean score of 72 on a math test. After the teacher realized that one of the questions had an
alternative correct answer, he gave 4 points each to the 7
students who had given the alternative answer. What is the new
mean test score?

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

(3x-8) or (3x+8)

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
