If you are looking for the fraction of total income spent, the answer would be 7/8.
3/8, 2/5, 1/10
Make them similar fractions, use LCD (in this case, 40)
They become
15/40, 16/40, 4/40
Add
15/40 + 16/40 + 4/40
= 35/40, or, simplified, 7/8

Answer:
AC 5
AB = 3
Step-by-step explanation:
AC = distance between the points
C-A = 3 - -2 = 3+2 = 5
The distance is 5
AB = distance between the points
B-A = 1 - -2 = 1+2 = 3
The distance is 3
Answer:
The required linear function is: f(x) = 
Step-by-step explanation:
We are given that f(x) is a linear function and it takes the value 9 when x = 2 and 14 when x = -1.
Now the general form of any linear function is: f(x) = ax + b.
Substituting these values in the general form we get:
f(2) = 9 = 2a + b
f(-1) = 14 = -a + b
Solving these two equations we get:
b = 37/3
Substituting this in the second equation to find 'a'.
a = -5/3
Therefore, the function f(x) = 
x + 
.
Answer: {x,y} = {4,2}
[1] x - 4y = -4
[2] 5x - 4y = 12// Solve equation [1] for the variable x
[1] x = 4y - 4
// Plug this in for variable x in equation [2]
[2] 5•(4y-4) - 4y = 12
[2] 16y = 32
// Solve equation [2] for the variable y
[2] 16y = 32
[2] y = 2
// By now we know this much :
x = 4y-4
y = 2
// Use the y value to solve for x
x = 4(2)-4 = 4
Step-by-step explanation:
Answer:
The slope is -4 (c)
Step-by-step explanation:
I used the slope-intercept form y= mx + b to find the slope m.
Hope this helps:)
