Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the g

Shtirlitz [24]

Answer:

The equation in the slope-intercept form is

y = -5x - 41

Step-by-step explanation:

The given equation in the question is;

y = -5x + 2

The equation of a straight line graph can be written in the form;

y = mx + c

where m is the slope and c is the intercept

From here, we can see that the slope m is -5

Since the line is parallel to the new line we are trying to write its equation, it means that they have the same value of intercept.

Hence, the slope of the new line is also -5

Now, we can write the equation of the new line as;

y = -5x + c

we need to get the value of c here however

To get the value of c, we need to input the value of x and y

From the graph, x = -7 and y = -6

Substituting these values, we have;

-6 = -5(-7) + c

-6 = 35 + c

c = -6 -35

c = -41

So the equation of the new line will be;

y = -5x - 41

The lengths of the sides of the triangle are 13cm, 14 cm, and 15 cm. Is the triangle a right triangle?

Helga [31]

Answer:

No, it is not a right triangle.

Step-by-step explanation:

If the triangle was a right triangle, then the Pythagorean Theorem states that a^2 + b^2 = c^2. Let's test it on this triangle:

13^2 + 14^2 = 365, or c^2. If this is a right triangle, c should equal 15.

However, sqrt(365) = 19.1, which is not 15. So, the triangle is not a right triangle.

Jeff can weed the garden twice as fast as his sister Julia. Together they can weed the garden in 3 hours. How long would it take

Leona [35]

<h2>Hello!</h2>

The answer is:

The correct option is:

A) Jeff, 4.5 hours; Julia 9 hours.

<h2>Why?</h2>

To solve the problem, we need to write two equations using the given information.

So, writing the first equation we have:

We know that Jeff can weed the garden twice as fas as his sister Julia, so:

$JeffRate=2JuliaRate$

Also, from the statement we know that they can weed the garden in 3 hours, so, writing the second equation we have:

$JeffRate+JuliaRate=\frac{1garden}{3hours}$

Then, we need to substitute the first equation into the second equation in order to isolate Julia's rate, so, solving we have:

$JeffRate+JuliaRate=\frac{1garden}{3hours}$

$2JuliaRate+JuliaRate=\frac{1garden}{3hours}$

$2JuliaRate+JuliaRate=\frac{1garden}{3hours}$

$3JuliaRate=\frac{1garden}{3hours}$

$JuliaRate=\frac{1garden}{3hours*3}=\frac{1garden}{9hours}$

We have that Julia could weed the garden by herself in 9 hours.

So, calculating how long will it take to Jeff, we have:

$JeffRate=2*JuliaRate\\\\JeffRate=2*\frac{1garden}{9hours}=\frac{2garden}{9hours}=\frac{1garden}{4.5hours}$

We have that Jeff could weed the same garden by himself in 4.5 hours.

Hence, the correct option is:

A) Jeff, 4.5 hours; Julia 9 hours.

Have a nice day!
