Which values are solutions to the inequality below?

1 answer:

4 0

Which numbers are greater than 10.
A, C, D, E, F are all greater than 10.

Small trick in remember is the open face of a greater than or less than sign wants to "eat" the larger number. i.e. 100 > 10 or 43 < 68

Answer all three for 40 points

Stolb23 [73]

So remember that with more than one pair of parentheses, you have to start from the inside and make your way outside.

Firstly, on the left side, solve 5+2 and on the right side solve 4 × 3:

$4[3(7)]=95-12$

Next, on the left side, solve 3 × 7 and on the right side solve the subtraction:

$4[21]=83$

Lastly, solve the remaining multiplication on the left side and the answer is $84= 83$

<u>Since 84 is not equal to 83, the correct answer is the second option.</u>

For this, plug 5 into the z variable to solve.

$3*5=2*5+5\\15=10+5\\15=15$

<u>Since 15 = 15 is true, your answer is the first option.</u>

So for this, it's a similar process as Question 2 except that you are plugging in 0 into the x variable to solve:

$8-4*0=4*0\\8-0=0\\8=0$

<u>Since 8 = 0 is a false statement, the correct answer is the second option.</u>

Quadratics need help making parabola

timama [110]

Answer:

The equation of the parabola is $y = \frac{1}{3}\cdot x^{2}-\frac{4}{3}\cdot x -4$ , whose real vertex is $(x,y) = (2, -5.333)$ , not $(x,y) = (2, -5)$ .

Step-by-step explanation:

A parabola is a second order polynomial. By Fundamental Theorem of Algebra we know that a second order polynomial can be formed when three distinct points are known. From statement we have the following information:

$(x_{1}, y_{1}) = (-2, 0)$ , $(x_{2}, y_{2}) = (6, 0)$ , $(x_{3}, y_{3}) = (0, -4)$

From definition of second order polynomial and the three points described above, we have the following system of linear equations:

$4\cdot a -2\cdot b + c = 0$ (1)

$36\cdot a + 6\cdot b + c = 0$ (2)

$c = -4$ (3)

The solution of this system is: $a = \frac{1}{3}$ , $b = - \frac{4}{3}$ , $c = -4$ . Hence, the equation of the parabola is $y = \frac{1}{3}\cdot x^{2}-\frac{4}{3}\cdot x -4$ . Lastly, we must check if $(x,y) = (2, -5)$ belongs to the function. If we know that $x = 2$ , then the value of $y$ is:
