The table of values models the quadratic function y = x2 + 7x – 9. What are the missing y-values in the table for the x-values?
Answers
The answer is letter B.
y = x² +7x-9
y= (-2)²+7(-2)-9
y=4+-14-9
y=-19
y=(-1)²+7(-1)-9
y=1+-7-9
y=-6+-9
y= -15
y=(0)²+7(0)-9
y=0+0-9
y=-9
y=(1)²+7(1)-9
y=1+7-9
y=8-9
y= -1
y=(2)²+7(2)-9
y=4+14-9
y=18-9
y=9
The missing values of the given quadratic function are option (b)-19,-15,-9,-1,9
What is a quadratic function?Quadratic function is an function which contains one unknown variable and the highest power of this unknown variable is 2. Let x be the unknown variable then the quadratic function y in x is given by
y = ax²+bx+c, where a, b, c are constants and a≠0
Given that a quadratic function y is:
y = x² +7x -9
Value of y when x = -2
y(-2) = (-2)² +7(-2) -9 = -19
Value of y when x = -1
y(-1) = (-1)² +7(-1) -9 = -15
Value of y when x = 0
y(0) = (0)² +7(0) -9 = -9
Value of y when x = 1
y(1) = (1)² +7(1) -9 = -1
Value of y when x = 2
y(2) = (2)² +7(2) -9 = 9
The missing values in the table are -19,-15,-9,-1,9
Therefore, option b is correct option.

O 7x - 2
O x + 2
Ox-4
O None of the above
Answers
Answer:
We conclude that 'None of the above' is the correct answer.
Step-by-step explanation:
Given the expression
[tex]7x^2\:-\:12x\:-\:4[/tex]
Breaking the expression into groups
[tex]7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)[/tex]
Factor out [tex]x[/tex] from [tex]7x^2\:+\:2x[/tex]
[tex]=x\left(7x+2\right)[/tex]
Factor out -2 from [tex]\left(-14x-4\right)[/tex]
[tex]=-2\left(7x+2\right)[/tex]
so the expression becomes
[tex]7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)[/tex]
[tex]=x\left(7x+2\right)-2\left(7x+2\right)[/tex]
Factor out the common term [tex]7x+2[/tex]
[tex]=\left(7x+2\right)\left(x-2\right)[/tex]
Therefore, from the given options, we conclude that 'None of the above' is the correct answer.

71 2/3 as a fraction
Answers
Answer:
215/3
Step-by-step explanation:
71 multiplied by 3 (denominator) + 2 (remainder) divided by 3
The improper fraction for the given mixed fraction is 215/2.
The given fraction is [tex]71\frac{2}{3}[/tex].
These are just improper fractions written as a sum of whole number and a proper fraction. (improper fraction has the upper value(also called numerator) bigger or equal to denominator(the bottom value) and proper fraction has numerator value is less than that of the denominator)
They are written and can be converted to fraction as: [tex]a\frac{b}{c} = \frac{(a\times c)+b}{c}[/tex]
Now, [tex]71\frac{2}{3}=\frac{71\times3+2}{3}[/tex]
= (213+2)/3
= 215/3
Therefore, the improper fraction for the given mixed fraction is 215/2.
