Answer: If you want the graph of f(x)=3x-2 and f(x)=x-2 then
Step-by-step explanation:
the blue line is f(x)=3x-2 and the green line is f(x)=x-2
f(x) is the same thing as y so all you have to do is y=3x-2 in a graphing calculator and you will get your answer
1. Since 12 took both, subtract 12 from 20 and 25.
Now we have 8 taking only chemistry, 13 taking only biology, and 12 taking both. Add all those together to get 33.
Subtract 33 from 50 to get 17, which is the number of students taking neither.
2. He had 3 nickels, 1 quarter, and 6 dimes.
This is an equation that represented his coins:
3n + 1q + 6d = 1.00
3 x .5 = .15 1 x .25 = .25 6 x .10 = .60 .60 + .25 = .85 .85 + .15 = 1.00
3. Add together 7 and 11 to get the 5th and 6th graders: 18 students.
The remaining 4th graders make up 1/3 of the team, so 18 is 2/3 of the team.
Find 1/3 by dividing 18 by 2 to get 9.
There are 9 4th graders.
Hope this helps!
Answer:
9y+45
Step-by-step explanation:
just multiply 9 by (y+5) that's what it means when it's right next to the parentheses without a sign in the middle.
Answer: -4
Step-by-step explanation: I am guessing you meant ...99 + 2(8*3)...
3x + 99 + 2(8 x 3) = 135
3x + 99 + 2(24) = 135
3x + 99 +48 = 135
3x + 147 = 135
(3x + 147) - 147 = (135) - 147
3x = -12
(3x) ÷ 3 = (-12) ÷ 3
x = -4
The answer should be B) False because it can only be contained in exactly one plane.
