Answer:

Step-by-step explanation:
First create an equation in slope-intercept form, y = mx + b. To do this, find the rate of change or slope (m), and the y-intercept (b).
Using two pairs, (-7, -3) and (-8, -4),

m = 1
To find b, substitute m = 1, x = -7 and y = -3 into y = mx + b.
Thus:
-3 = (1)(-7) + b
-3 = -7 + b
-3 + 7 = b
4 = b
b = 4.
Replace y with f(x), m with 1 and b with 4 in y = mx + b.
The function would be:

Answer:
x = 4y/3
Step-by-step explanation:
y = 3x/4
Multiply both sides by 4.
4y = 3x
Divide both sides by 3.
x = 4y/3
Answer:
x=11/2
Step-by-step explanation:
1/2x-4=7+1/6x
1/2x-1/6x=7+4
6*1/2x-1/6*6=11 As 6 is the Lcm and we have to multiply it to the fractions.
3x-x=11 As 6 divided by 2 is 3 and 3 multiplied by x is 3x.
2x=11
x=11/2 OR 5 1/2
Answer:
Step-by-step explanation:
x / x + 7 = 21/27
cross multiply
27x=21x+147
6x = 147
x=24.5
