If f(x) = 6x +5 and g(x) = 2x – 7 find (fºg)(x)
Answer:
f(g(x)) = 12x - 37
Step-by-step explanation:
Step 1: Define
f(x) = 6x + 5
g(x) = 2x - 7
Step 2: Find f(g(x))
f(g(x)) = 6(2x - 7) + 5
f(g(x)) = 12x - 42 + 5
f(g(x)) = 12x - 37

6. A landscaping company ordered 13 plants and 4 trees for a total of $487. If plants are $8 each write and solve a linear equation to find the cost for each tree
Answer:95.75
Step-by-step explanation:
13x + 4y = 487
13*8 + 4y = 487
4y = 487 - 13*8
y = (487 - 13*8)/4
y = dollars per tree = 95.75
Answer:
trees are $95.75
Step-by-step explanation:
13(8) + 4t =487
104 + 4t= 487
104 -104 + 4t = 487 -104
4t = 383
4/4t = 383/4
t = 95.75
What value(s) of x make the following equation true?
2x - 6 = 3x + 1 - 2x - 7
Answer:
x = 0
Step-by-step explanation:
2x−6=3x+1−2x−7
Step 1: Simplify both sides of the equation.
2x−6=3x+1−2x−7
2x+−6=3x+1+−2x+−7
2x−6=(3x+−2x)+(1+−7)(Here we Combine Like Terms)
2x−6=x+−6
2x−6=x−6
Step 2: Subtract x from both sides.
2x−6−x=x−6−x
x−6=−6
Step 3: Add 6 to both sides.
x−6+6=−6+6
x=0
