Answer:
19x²-2x+2
Step-by-step explanation:
stepss
4x^2-5x+3*5x^2+3x+2
then group the terms
4x²+3*5x²-5x+3x+2
add sim elements
4x²+3*5x²-2x+2
multiy the numbers
4x²+15x²-2x+2
add sim elements
19x²-2x+2
the answer is 19x²-2x+2
4. line them up least to greatest and the one in the middle is the median, which is 4.
Answer:
The answer is y=3x+2
Step-by-step explanation:
y-y=m(x-x¹)
y-5=3(x-1)
y-5=3x-3
+5 +5
y=3x+2
For this case, the first thing we must do is define variables.
We have then:
n: number of cans that each student must bring
We know that:
The teacher will bring 5 cans
There are 20 students in the class
At least 105 cans must be brought, but no more than 205 cans
Therefore the inequation of the problem is given by:
Answer:
105 <u><</u> 20n + 5 <u><</u> 205
the possible numbers n of cans that each student should bring in is:
105 <u><</u> 20n + 5 <u><</u> 205
It is 350% I think, because you are trying to find how many groups of 2 go into 7. So, you have to divide 7 by 2. You get 3.5. 3.5 in percentage form is 350%
