Answer:
B) x^2y + 7
Step-by-step explanation:
we are given
We can use grouping method to factor it
now, we can factor common terms
so, we get
we can see that x^2y+7 is one of factor
Answer:
4x+10=y
hope it is correct answer for it.
C
Because the graph of the line is y = 2x + 2
The graph is shaded above the line, so we want y values above the line and since it is shaded in (red and not dashed), we want the values above and on the line (aka greater than or equal to SIGN)
Answer:the price for one shirt is $7.5
the price for one pair of pants is $18.5
Step-by-step explanation:
Let x represent the price for one shirt.
Let y represent the price for one pair of pants.
Lisa goes to the mall one day and buys four shirts and three pairs of pants for $85.50. This means that
4x + 3y = 85.5 - - - - - - - - - -1
She returns the next day and buys three shirts and five pairs of pants for $115.00. This means that
3x + 5y = 115 - - - - - - - - - - - 2
Multiplying equation 1 by b3 and equation 2 by 4, it becomes
12x + 9y = 256.5
12x + 20y = 460
Subtracting, it becomes
- 11y = - 203.5
y = - 203.5/ -11 = 18.5
Substituting y = 18.5 into equation 1, it becomes
4x + 3×18.5 = 85.5
4x + 55.5 = 85.5
4x = 85.5 - 55.5 = 30
x = 30/4 = 7.5
Answer:
the last one
Step-by-step explanation:
when looking for the function we have to know that none of the x values can repeat
in the first one the x value -5 repeats twice so that cannot be the answer
in the second one the x value 2 repeats twice so that cant be the answer
in the third one the x value -7 repeats twice so that also cannot be the answer
in the last one each x value has a different y value or every input has a different output therefore this one is the right answer
hope this helps :D
