Answer:
-32
Step-by-step explanation:
-4 + f(8) + 3 x g(-7) = ?
To find f(8), look at each of the f(x) function and find x = 8. The y value is the answer you will plug in for f(8). The same goes for g(-7), but you will be looking at the g(x) function at x = -7.
f(8) = -4
g(-7) = -8
Make sure you solve in the correct order using PEMDAS.
-4 + (-4) + 3 x (-8) = -32
Answer:B At least 4 pounds but less than 6 pounds.

Answer:
y = -1/2x +11/2
Step-by-step explanation:
slope finding: -5+6/1-3 = -1/2
equation making: y+5 = -1/2(x-1)
rearranging: y = -1/2x +11/2
2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.

Answer:
38 or 38.33 cups of water.
Step-by-step explanation:
You need 5 cups of water for every 3 ounces of medication. We can set up a proportion: #oz of medication/#cups of water= #oz of medication/# cups of water. We can plug in some numbers from the problem.
3/5=23/n. You can use any variable, but I'm using n for how many cups of water Jim will need for 23 ounces of medication.
We can cross multiply: 3*n=5*23.
3n=115
We divide both sides by 3.
n=38.3333333.......
Rounding to the nearest whole number, Jim will need 38 cups of water, or 38.33 cups if you're rounding to the nearest hundredth.
Hope this helps :)
