Step-by-step explanation: I think so on edge -4 must be factored from -4x^2-7
Number of boys enrolled is 105
<em><u>Solution:</u></em>
Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls
There are 245 total preschoolers
Ratio of boys and girls = 3 : 4
Number of boys : number of girls = 3 : 4
Let the number of boys be 3x
Let the number of girls be 4x
Total number of preschoolers = 245
Therefore,
number of boys + number of girls = 245
3x + 4x = 245
7x = 245
x = 35
Number of boys = 3x = 3(35) = 105
Thus number of boys is 105

Step-by-step explanation:
X(3, -1) → x = 3, y = -1
x - no change
y:
calculate the distance between X and y = 1
1 - (-1) = 1 + 1 = 2
calculate the value of y in coordinates of X':
1 + 2 = 3
Answer: (3, 3)
