GRADES A professor announces that course grades will be computed by taking 40% of a student's project score (0-100 points) and adding 60% of the
student's final exam score (0-100 points). If a student gets an 86 on the project,
what scores can she get on the final exam to get a course grade of at least 90?

how do you solve this?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

sorry i just need to anwers this to get points

step-by-step explanation:

lol.

it's ok we all do this sometimes.
