Answer:
3/4 or 0.75
Step-by-step explanation:
the equation is in slope-intercept form
y=mx+b
where m is the slope and b is the y-intercept.
you have already found the y-intercept to be -2, so now we just have to find the slope.
slope is also known as rise/run. so if we start at the y-intercept of -2, we can rise (go up) 3 units and then run (go over) 4 units until we reach another point on the line.
so the slope is 3/4 which is also equal to 0.75 units
Answer:
x = 5/2 = 2.5
Step-by-step explanation:
Given
f(x) = 3x-7
g(x) = x+2
g^(-1)(x) = f(x)
First find g^(-1)(x) = h(x)
x=h(x)+2
h(x) = x -2
h(x) = x - 2 = f(x) = 3x-7
solve for x
x-2 = 3x -7
-2 + 7 = 3x - x
2x = 5
x = 5/2
Answer:
A
Step-by-step explanation:
4x +3y = 7.43
5x +2y = 7.03
8x +6y = 14.86
-15x -6y = -21.09
-7x = -6.23
x = 0.89
The answer is A
