Note that two negatives = one positive

so: -(-13) = +13

Combine the two numbers

-11 + 13 = 13 - 11

13 - 11 =2

2 is your answer

hope this helps

Answer:

x = 3 and y = 1

Step-by-step explanation:

The given equations are :

6x + 14y = 32 ...(1)

6x - 14y = 4 .....(2)

Add equation (1) and (2) :

6x + 14y + 6x - 14y = 32 + 4

12x = 36

x = 3

Put the value of x in equation (1)

6(3) + 14y = 32

18 + 14y = 32

14y = 32-18

14y = 14

y = 1

Hence, the value of x is 3 and y is 1.

The mean age of 5 people in a room is 40 years. A person enters the room. The mean age is now 36. What is the age of the person

Igoryamba

Answer:

$\boxed{\sf \ \ \ age = 16 \ \ \ }$

Step-by-step explanation:

Hello,

as the mean age of 5 people is 40

it means that the sum of the 5 ages is 40*5=200

now a person enters the room, let's note x his age

the new mean is

$\dfrac{200+x}{6}=36$

$200+x=6*36=216\\ x = 216-200=16\\$

So the age of the new person is 16

hope this helps

Write the equation of the line perpendicular to y = *x+7 with a y-intercept of (0-1)

I am Lyosha [343]

Answer: y = -x - 1

Step-by-step explanation:

Use the Point-Slope formula: $y - y_1=m_{\perp}(x-x_1)$ where

(x₁ , y₁) is the given point (0, -1)
$m_{\perp}\ \text{is the opposite reciprocal slope of the given line}\implies m_{\perp}=-1$

Insert those values into the formula and solve for y:

y - (-1) = -1(x - 0)

y + 1 = -x

y = -x - 1
