Answer:
a. when x=1 so substitute 1 to any X in the given equation.
y=-3(1)+2.5
y=-3+2.5
y=-0.5
b.when x is -1.5 so substitute -1.5 to any x in the equation
y=-3(-1.5)+2.5
y=-4.5+2.5
y=-2
Answer:
D
Step-by-step explanation:
30.20 * 15% (or 0.15) = 4.53
4.53 is about 4.50
We determine line m as follows:
*First, by theorem we have the following:

Here m1 & m2 are the slopes of two perpendicular lines. For all lines that are perpendicular that is true, so we calculate the slope of line m using the slope of the function given [Which has a slope of 7/4]:

So, the slope of line m is -4/7. Now, using this slope and the point (-1, 4) we replace in the following expression:

Here x1, y1 & m1 are the x-component of the point, the y-component of the point, and the slope of the line respectively, so we replace and solve for y:


And that last function of y is the line m.
2a(b+3+4bc)
just take out the greatest common factor :)
