Answer:
smart dot company would be c=.50t+12
communication plus would be c=2.50t
Step-by-step explanation:
smart dot starts with $12 a month and adds $0.50 for each hour of internet use. communication plus has no starting fee so it just adds $2.50 for each hour of internet use.
So then for the table you would put the number given for time in for the letter t and find what c would be. This would then find your cost for that amount of hours. To get you started smart dot company starts off with 0 hours so put that in for t being c=0.50(0)+12 and c=12. Communication plus also starts with 0 so it would be c=2.50(0) and c=0
Then you graph once you have both values you can graph having x=time and y=cost

Answer:
Correct option is C). {(0, −5), (2, 9), (−3, −26)}
Step-by-step explanation:
Given function is f(x)=7x-5.
Here, Options are given ordered pair
Let, x=0
f(x)=7x-5
f(0)=7(0)-5
f(0)=(-5)
The ordered pair is (0,-5)
Let, x=2
f(x)=7x-5
f(2)=7(2)-5
f(2)=9
The ordered pair is (2,9)
Let, x=(-3)
f(x)=7x-5
f(-3)=7(-3)-5
f(-3)=(-26)
The ordered pair is (-3,-26)
Thus, Correct option is C). {(0, −5), (2, 9), (−3, −26)}
Answer:
Step-by-step explanation:
To round 4.9 to nearest tenth means to round the numbers so you only have one digit in the fractional part. 4.9 already has only one digit in the fractional part. Thus, 4.9 is already rounded as much as possible to the nearest tenth and the answer is: 4.9
Answer:
There are 78 female members of the House of Representatives and 14 female members of the Senate.
Step-by-step explanation:
Let h equal the amount of female members of the House of Representatives and s equal the amount of female members in the Senate.
Since the amount of female officials in Congress is 92, and is made up of the House of Representatives and the Senate, we can represent this as the equation h+s=92
Since there are 64 more female members in the House of Representatives than female Senators, the senators would need 64 more female members to have the same amount as the House of Representatives. We can represent this as h=s+64.
Substituting, we get s+64+s=92, which simplifies to 2s+64=92. Subtracting 64 from both sides, we get 2s=28, which equals to s=14. There are 14 female senators. Substituting back into h+s=92, 14+s=92, and s=78. Therefore, there are 78 female members of the House of Representatives and 14 female members of the Senate.
