Answer: i dont understand
Step-by-step explanation:
The computation shows that the value of blue which is represented by x is 12.
<h3>How to calculate the value?</h3>
From the information given, it was stated that 30 people were in the kindergarten.
Green = 10
Red = 8
Blue (x) = 30 - (10 + 8)
= 30 - 18
= 12
Since the teacher want to paint the class with the most favorite color, the appropriate color to use will be blue.

Answer:
29
Step-by-step explanation:
h(x) = 2 * x^2 - 3
h(-4) = 2* (-4)^2 - 3
h(-4) = 2 * 16 - 3
h(-4) = 32 - 3
h(-4) = 29
Answer:
x1= -4, x2 = 7
Step-by-step explanation:
Move expression to the left-hand side:
1/4x-3/4-7/x=0
Write all the numerators above a common denominator:
x^2 - 3x - 28 /4x =0
When the quotient of expressions equal 0, the numerator has to be 0
x^2 + 4x - 7x - 28 = 0
x(x+4) - 7(x+4) =0
(x+4) × (x-7) =0
Separate into possible cases:
x+4=0
x-7=0
Answer:
The equivalent function: 
Step-by-step explanation:
The x-intercepts of the given function on the graph can be obtained by equating the function to zero.
This is because on the x-axis, the y-coordinate is zero.
The function that has the same x-intercepts on the graph from the given options is:
Alternate Method:
The answer can also be obtained by factorizing the question.
