-2/(a+b)
Explanation: you are dividing negative two by the sum of a and b so you would put a+b in parentheses as the denominator and then put -2 as the numerator

Select the two values of x that are roots of this equation.<br>x + 2x - 6 = 0

VLD [36.1K]

For this case we must solve the following quadratic equation:

$x ^ 2 + 2x-6 = 0$

Where:

$a = 1\\b = 2\\c = -6$

The solution is given by:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Substituting:

$x = \frac {-2 \pm \sqrt {2 ^ 2-4 (1) (- 6)}} {2 (1)}\\x = \frac {-2 \pm \sqrt {4 + 24}} {2}\\x = \frac {-2 \pm \sqrt {28}} {2}\\x = \frac {-2 \pm \sqrt {2 ^ 2 * 7}} {2}\\x = \frac {-2 \pm2 \sqrt {7}} {2}\\x = -1 \pm \sqrt {7}$

Thus, we have two roots:

$x_ {1} = - 1+ \sqrt {7}\\x_ {2} = - 1- \sqrt {7}$

ANswer:

$x_ {1} = - 1+ \sqrt {7}\\x_ {2} = - 1- \sqrt {7}$

Which graph represents y = RootIndex 3 StartRoot x EndRoot + 2?

mojhsa [17]

Answer:

see attachment

Step-by-step explanation:

We want to choose the graph that represents:

$y = \sqrt[3]{x} + 2$

We know the parent function will be:

$y = \sqrt[3]{x}$

There has been a vertical shift upward by 2 units.

Therefore the graph of

$y = \sqrt[3]{x} + 2$

is obtained by shifting the parent function up 2 units.

Its y-intercept will move from 0 to 2.

The graph is shown in attachment.

In triangle XYZ, mZZ > mZX + mZY. Which must be true about AXYZ?

Semmy [17]

Answer:

D. m∠X + m∠Y < 90°

Step-by-step explanation:

<h3>Given</h3>

ΔXYZ with m∠Z > m∠X + m∠Y

<h3>Options</h3>

<u>m∠X + m∠Z < 90°</u>

incorrect, the sum of these two angles should be > 90°

<u>m∠Y > 90°</u>

incorrect, it should be < 90°

<u>∠X and ∠Y are complementary</u>

incorrect as angle Z is greater that the sum of angles X and Y, then sum of three angles would be greater than 180°

<u>m∠X + m∠Y < 90°</u>

correct, this is the only possible option
