Answer:

(5, -7)

Step-by-step explanation:

Let the point (6, -5) be M, and point B has coordinates of (x, y)

As the point A(7, -3) reflects over the point M, it becomes the midpoint of segment AB

<u>Using midpoint formula, finding the coordinates of the point B</u>

6 = (7 + x)/2 ⇒ 7 + x = 12 ⇒ x = 12 -7= 5
-5 = (-3 + y)/2 ⇒ -3 + y = -10 ⇒ y = -10 + 3 = -7

So the point B is (5, -7)

Prove: If a^2-a is even then a is even.

Alla [95]

This is not always true. Consider $a=3$ . Then $3^2-3=9-3=6$ is even, but $a$ is odd.

Write the Recursive Rule for the sequence:

skad [1K]

A formula is recursive if it expresses the term $a_n$ in terms of the previous one(s) $a_{n-1},\ a_{n-2},\ \ldots,\ a_1$

In this case, every term is 7 more than the previous one, so the formula for $a_n$ will only involve $a_{n-1}$ :

$a_n = a_{n-1} + 7$

In fact, this formula is simply saying: for every index $n$ , the term with that index is 7 more than the term before.

Also, we have to specify the starting point (otherwise we would go backwards indefinitely), so the complete recursive formula is

$a_n = a_{n-1} + 7,\quad a_1 = 2$

which means: start with 2 and generate every other term by adding 7 to the previous one.

Find the sum of the squares of the roots of 3x^2 + 4x + 12 = 0

Contact [7]

Answer:

-56/9

Step-by-step explanation:

Let p and q be the roots of the equation.

So, here's how we're gonna work it out:

${p}^{2} + {q}^{2} = \\ {p}^{2} + {q}^{2} +2 pq - 2pq = \\ ( {p}^{2} +2pq + {q}^{2}) - 2pq = \\ {(p + q)}^{2} - 2pq$

Vieta's formulas give us the sum and the product of the roots of a quadratic equation. Using them we obtain:

p + q = -b / a = - 4 / 3
p × q = c / a = 12 / 3 = 4

${(p + q)}^{2} - 2pq = \\ {( - \frac{ 4}{3} )}^{2} - 2 \times 4 = \frac{16}{9 } - 8 = \\ \frac{16 - 72}{9} = - \frac{56}{9}$

33% of what number is 1.45

MAVERICK [17]

33% of 4.3939 is 1.45

Convert your percentage into a decimal:
$\frac{33}{100} = 0.33$

Divide both of your decimals:
$1.45 \div 0.33 = 4.3939$
