Answer:
1a - no
1b - yes
1c - no
2 - 1.5 grams of protein
3 - a solution to this equation tells us how many grams of protein/fat there could be depending on how many grams of the other there are. a solution to this is 6 grams of protein and 4 grams of fat.
Step-by-step explanation:
1a
4(5)+9(2)=60
20+18=60
38=60
the equation is false
1b
4(10.5)+9(2)=60
42+18=60
60=60
the equation is true
1c
4(8)+9(4)=60
32+36=60
68=60
the equation is not true
2
plug in 6 for the f value
4p+9(6)=60
4p+54=60
subtract 54 from both sides
4p=6
divide both sides by 4 to get p alone
p=1.5
3
a possible solution can be seen by graphing the equation using the intercepts. the intercepts for this equation are (15,0) and (0,6.6). attached is an image of the graph. the points where the line crosses are possible solutions. the line crosses the point (6,4) on the graph, which represents 6 grams of protein and 4 grams of fat. you can also check this by plugging these values into the equation.
You need to use PEMDAS
So first you do the parenthesis.
8*1=8.
So now re-write the problem.
50+10*8+2
Now you are going to multiply.
10*=80
Now re-write the problem again.
10+80+2
10+80=90+2=92
So the answer to this problem is 92.
Answer:
Step-by-step explanation:
b would be 0
your slope is rise/run. up one and over three. up one and over three. so 1/3
write it as y=1/3x+0, or y=1/3x
It would be 0.008 because you line up the decimals and multiply
