Answer:

$(3, 7)$

Step-by-step explanation:

(4/3)P -(4/3)A + A = B . . . . . . add A

(4P -A)/3 = B . . . . . . . . . . . . . simplify

Then the coordinates of point B are ...

B = (4(1, 6) -(-5, 3))/3 = (9, 21)/3

B = (3, 7)

If m<2=35° and <1and <2 form a right angle. Find m <1.

yaroslaw [1]

To solve this problem, we just need to set up a simple equation. We have that angles 1 and 2 add up to equal a right angle, or 90°, and that m<2 is 35°, so we just have to do a bit of subtraction.

<1 + <2 = 90 Given
<1 + 35 = 90 Substitute 35 for <2
<1 = 55° Subtract 35 from both sides to get rid of it, since subtraction is the opposite of addition.

Therefore, m<1 = 55°.

Hope this helps!

The product of a positive number and 14 more than seven times the number is 105. Find the two numbers. first number =______ and

Nostrana [21]

Let the positive number be $x$

The expression is
$x(14+7x)=105$ ⇒ expanding the bracket gives,
$14x+7 x^{2} =105$ ⇒ rearranging to equate one side to zero
$7x^{2} +14x-105=0$ ⇒ Dividing each term by 7 to simplify
$x^{2} +2x-15$ ⇒ Factorising gives
$(x+5)(x-3)=0$
$x=-5$ and $x=3$

Hence, the first number is -5 and the second number is 3
