Answer:
x = 1/2
Step-by-step explanation:
4x-3 + 5 = 2x + 7 - 8x
Combine like terms
4x +2 = 7-6x
Add 6x to each side
4x+2+6x = 7-6x+6x
10x+2 = 7
Subtract 2 from each side
10x+2-2 = 7-2
10x = 5
Divide by 10
10x/10 = 5/10
x = 1/2
Answer:
f(x) = -7x + 1
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is slope
b is y-intercept
--------------------------
y decreases by 7 for each increase of 1 in x
slope = -7
to find "b" plug in one of the points and m = -7
using point (3, -20)
y = mx + b
-20 = -7(3) + b
-20 = -21 + b
b = 1
The equation is
f(x) = -7x + 1

Answer:
d. 23
Step-by-step explanation:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23
hope this helps
