Answer:
Step-by-step explanation:
7x+3
The question is asking for you to plug in each number in the brackets into x and solve for y, or f(x), g(x), etc. I will do no. 19 as an example:
f(x) = -3x + 1
This problem has the domains -2, -1, and 0. First, we'll start with -2:
f(x) = -3(-2) + 1
f(x) = 6 + 1
f(x) = 7
Now -1:
f(x) = -3(-1) + 1
f(x) = 3 + 1
f(x) = 4
Lastly, 0:
f(x) = -3(0) + 1
f(x) = 0 + 1
f(x) = 1
For question 23, we can use the distance formula, which is ratextime. The domain in this case is time (t). You can set up a function like this: d(t) = 60t
1. 9,670
2. 967
3. 96.7
4. 49.32
5. 493.2
6. 4,932
7. 49,320

first brand quantity is x
2nd brand quantity is y
x+y=30
0.3x+0.55y=0.35(30) or 0.3x+0.55y=10.5
solve for x and y
multiply first equation by -0.3
-0.3x-0.3y=-9
add to 2nd equation
0.3x-0.3y=-9
<u>0.3x+0.55y=10.5 +</u>
0x+0.25y=1.5
0.25y=1.5
divide both sides by 0.25
y=6
sub back
x+y=30
x+6=30
x=24
you need 24 gallons of the first brand and 6 gallons of the 2nd brand
Answer:
The answer is= 119 Bushels and a half(119.5)
Step-by-step explanation:
Equation related to the problem= 220-(67/4)·T=bushels of Beans left
After 6 days=
220-(67/4·)6=bushels of Beans left
Bushels of beans left=119.5---> You need to change the dot for a fraction
119.5 is 119 bushes and a half so
The answer is= 119 Bushels and a half(119.5)
