Answer:

The equation of a line in point-slope form is.

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯∣∣aay−y1=m(x−x1)aa∣∣−−−−−−−−−−−−−−−−−−−−−−

where m represents the slope and (x1,y1) a point on the line.

To calculate the slope use the gradient formula

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯∣∣∣aam=y2−y1x2−x1aa∣∣∣−−−−−−−−−−−−−−−−−

where (x1,y1) and (x2,y2) are 2 coordinate points.

here the 2 points are (-3 ,4) and (0 ,3)

let (x1,y1)=(−3,4) and (x2,y2)=(0,3)

⇒m=3−40+3

Step-by-step explanation:

this is guid to answer that hope it help to you mahar

Answer:

Here we want to graph the equations:

f(x) = y =(8/3)*x

and

g(x) = y = -(8/3)*x

To graph these you need to find some coordinate points of each one, and then connect them, such that the graph of these two equations can be seen below.

Where the blue one is f(x) and the green one is g(x)

We now want to look at the graph and find the point of intersection p.

By looking at the graph below, we can see that the intersection is at the origin, then p = (0,0)

Also remember that an intersection of two functions means that:

f(x) = g(x)

for that particular x value, then we can solve this for our functions and get:

(8/3)*x = -(8/3)*x

That equation is only true when x = 0

Then we have the intersection at x = 0, and the correspondent y value is given by f(0) or g(0) (will be the same value)

y = f(0) = (8/3)*0 = 0 = -(8/3)*0 = g(0)

Then we also found analytically that the intersection is in the point (0, 0)

Answer:

∠CBA = 132

Step-by-step explanation:

Bisectors split up an angle into two identical angles

Thus, 7x - 11 = 2x + 44

This is the equation we will use to solve for x

7x - 11 = 2x + 44

step 1 add 44 to each side

44 + 11 = 55

-11 + 11 cancels out

we now have 7x = 2x + 55

step 2 subtract 2x from each side

7x - 2x = 5x

2x - 2x cancels out

we now have 5x = 55

step 3 divide each side by 5

5x / 5  = x

55 / 5 = 11

we're left with x = 11

The question is asking for the measure of ∠CBA

To find the measure of ∠CBA we plug in 11 for x in one of the given expressions and multiply that by 2 ( this is because the two angles are identical so there is no need to find the measures of both because ∠CBD≅∠ABD )

7(11) - 11

7 * 11 = 77

77 - 11 = 66

66 * 2 = 132

Answer:

-3 - 1 = 4/9(-5 - 4)

Step-by-step Explanation:

Point-Slope form uses the formula y-y1=m(x-x1).

m is the slope, which they gave you, so you can substitute it into the formula:

y - y1 = 4/9(x - x1).

They also gave you a first point (-5, -3) So you can substitute the x and y of those into the formula as well.

-3 - y1 = 4/9(-5 - x1)

y1 and x1 are for another point. By drawing a graph and then using the rise and run of the slope (up 4 and over 9), you can get another point (as shown in the picture).

Substitute the x and y values of that point into the equation as well and you have your answer:

-3 - 1 = 4/9(-5 - 4)

Answer:

5 days.

Step-by-step explanation:

Jasmine has two options:

Rent skis at the resort for $30 per day.

Then if she rents the skis for N days, the cost will be:

C(N) = N*$30

Buy skis for $150

Now we can ignore the lift pass because she will pay that in both cases.

Now we want to find the number of days N such that the cost of renting is the same as the cost of buying.

Then we need to solve:

C(N) = $150

N*$30 = $150

N = $150/$30 = 5

So if you rent the skis for 5 days, you will pay the same as if you bought the skis.

Given :

A Straight line passes through A(-2,1) and B(2,-k).

The  line is perpendicular to a line 3y+2x=5 .

To Find :

The value of k.

Solution :

Let, slope of line is m.

We know, product of slope of in straight line is -1.

[tex]m \times \dfrac{-2}{3} = -1\\\\m = \dfrac{3}{2}[/tex]

We know, slope is given by :

[tex]\dfrac{y_2-y_1}{x_2-x_1} = \dfrac{3}{2}\\\\\dfrac{1-(-k)}{-2 - 2} = \dfrac{3}{2}\\\\\dfrac{1+k}{-4} = \dfrac{3}{2}\\\\k = -7[/tex]

Therefore, the value of k is -7.

Answer:

29 3/4 cups

Step-by-step explanation:

total amount of tanner in the 3 containers = sum of tanners in each container

total cups in containers b and c = 2/3 x 12 3/4

2/3 x 51/4 = 17/2 cups or 8 1/2 cups

total capacity = 8 1/2 + 8 1/2 + 12 3/4 = 17 + 12 3/4 = 29 3/4

Answer:x=57

Step-by-step explanation:

isolate x by subtracting 17 from both sides, you should get x = 74-17, which is 57.

The Area of the lens is equal to 50.24 cm²

The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.

Given here: Elliana is using a magnifying glass and radius of the magnifying glass has radius of 4 cm.

The formula for the area of a circle is A = πr², where r is the radius of the circle. The unit of area is the square unit, for example, m², cm², in², etc.

Thus Area of the lens of the glass is equal to A=πr²

                                                                              =3.14×4²

                                                                              =50.24 cm²

Therefore the len's Area is 50.24 cm²

Hence, The Area of the lens is equal to 50.24 cm²

Answer: C

Step-by-step explanation:

Answer:

42 minutes.

Step-by-step explanation:

We know that:

y = 0.2*x

is the equation that that defines the distance, in miles, that the boat travels in x minutes.

We know that the dolphins are at 8.4 miles from the boat.

Then when we have y = 8.4, this will mean that the boat reached the dolphins.

Then we need to solve the equation:

y = 8.4 = 0.2*x

for x

To do that, we just need to isolate x in one side of the equation, so we can just divide both sides by 0.2 to get:

8.4/0.2 = (0.2*x)/0.2

42 = x

And x is time in minutes, thus, the boat needs to travel for 42 minutes to reach the dolphins.
