Answer:

Let the integers are p and q.

In case both integers are positive or negative, you add the numbers up and apply their sign to the sum.

Examples:

10 + 88 = 98
-20 + (-15) = -35

In case one of the integers is negative and one positive.

p < 0, q > 0

Use absolute value in this case.

Subtract the numbers and apply the sign of the number with the greater absolute value.

Examples:

- 10 + 15 = |15 - 10| = |5| = 5
- 15 + 10 = - |15 - 10| = - |5| = -5

kari74 [83]

Given:

The equation of given line is

$y=3x-4$

A line is perpendicular to the given line and passes through the point (9,5).

To find:

The equation of the perpendicular line.

Solution:

We have,

$y=3x-4$

On comparing this equation with slope intercept form $y=mx+b$ , we get

$m=3$

It means, the slope of the given line is 3.

The product of slopes of two perpendicular lines is -1.

$m\times m_1=-1$

$3\times m_1=-1$

$m_1=-\dfrac{1}{3}$

Point slope form of a line is

$y-y_1=m(x-x_1)$

Where, m is the slope.

The slope of perpendicular line is $-\dfrac{1}{3}$ and it passes through the point (9,5). So the equation of the line is

$y-5=-\dfrac{1}{3}(x-9)$

$y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)$

$y-5=-\dfrac{1}{3}x+3$

Adding 5 on both sides, we get

$y-5+5=-\dfrac{1}{3}x+3+5$

$y=-\dfrac{1}{3}x+8$

Therefore, the equation of required line is $y=-\dfrac{1}{3}x+8$ .

Answer:

$\frac{1}{25}$

Step-by-step explanation:

using the rule of exponents

• $a^{-m}$ = $\frac{1}{a^{m} }$ , then

$5^{-2}$ = $\frac{1}{5^{2} }$ = $\frac{1}{25}$

The function y=60/x relates y, the time in hours that it takes Michael to travel to his grandparents’ house, to x, his average s

Paha777 [63]

Answer:

b) 60 is the distance in miles that must be travelled to get to Michael's grandparents' house

Step-by-step explanation:

hello

at the speed of x mph in 1 hour he travels x miles

so in 60/x hour he travels 60 miles

so 60 is the distance in miles that must be travelled to get to Michael's grandparents' house

another way to see it is as below

distance = vitesse * time so

time = distance / vitesse

hope this helps
