Find the slope of the line through each pair of points use the slope formula show your work (-9,-13), (-12,15)

Answer:

OK mate don't freak out its easy

First things first x and y are height and base and 10cm is hypotenuse.

40degree is the angle

Now.

The sin angle is an trigonometric angle which deals with height and hypotenuse.

It's formulae is...... Sin angle =height /hypotenuse

So sin 40 = x/10

X= 10 * sin 40

X= 10*0.64

Hence x=6.4 cm

Remainder sin 40 is 0.64

Again

The cos angle is an trigonometric angle which deals with base and hypotenuse

It's formulae is...... Cos angle =base /hypotenuse

So cos 40 = y/10

Y= cos 40 *10

Y= 0.76*10

Hence y = 7.6cm

Remainder cos 40 = 0.76.

Thank you

Answer:

[tex]y = \frac{3}{2} x + 2[/tex]

Step-by-step explanation:

In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} } [/tex]

Using the formula above,

[tex]slope = \frac{5 - ( - 4)}{2 - ( - 4)} [/tex]

[tex]m = \frac{5 + 4}{2 + 4} [/tex]

[tex]m = \frac{9}{6} [/tex]

[tex]m = \frac{3}{2} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{3}{2} x + b[/tex]

To find the value of b, substitute a pair of coordinates into the equation.

When x= 2, y= 5,

[tex]5 = \frac{3}{2} (2) + b[/tex]

5= 3 +b

b= 5 -3

b= 2

Thus, the equation of the line is [tex]y = \frac{3}{2} x + 2[/tex].

Answer:

7/3

Step-by-step explanation:

f(x) =7/(x+2)

g(x) = (x + 5)^2

f(g(-4))=

First find g(-4)

g(-4) = (-4+5)^2

        =(1)^2 =1

Then find f(1)

f(1)= 7/(1+2)

   = 7/3

let the last number be x

we know,

[tex] \boxed{mean = \frac{sum \: \: of \: \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]

So,

[tex] \hookrightarrow \: 8 = \dfrac{22 + x}{4} [/tex]

[tex] \hookrightarrow \: 8 \times 4 = 22 + x[/tex]

[tex] \hookrightarrow \: 32 = 22 + x[/tex]

[tex] \hookrightarrow \: x = 32 - 22[/tex]

[tex] \hookrightarrow \: x = 10[/tex]

therefore, the last number is 10.

Answer:

h(0) = 7

Step-by-step explanation:

by saying h(0) it is asking you to plug in 0 as the x value

3(0)^2 = 0

0 + 7 = 7

Answer:

Step-by-step explanation:

let x = the number of pounds of cheaper coffee.

Since the merchant is mixing this with more expensive coffee, then

x + 60 = the number of pounds of medium priced mixed coffee.

The equation is gotten from this

+  =  

(x)($40)  + (60)($90)   = (x + 60)($70) or

            40x + 5400 = 70(x + 60)

Solve that equation and get x = 40

Answer: 40 pounds of $40 coffee.

Answer:

AC = [tex]\sqrt{58}[/tex]

Step-by-step explanation:

Calculate AC using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A (0, - 2) and (x₂, y₂ ) = C (3, 5 )

AC = [tex]\sqrt{(3-0)^2+(5-(-2)})^2[/tex]

     = [tex]\sqrt{3^2+(5+2)^2}[/tex]

    = [tex]\sqrt{9+7^2}[/tex]

    = [tex]\sqrt{9+49}[/tex]

    = [tex]\sqrt{58}[/tex]

Answer:

[tex]y=\displaystyle\frac{1}{2}x+1[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept

We're given that the slope is [tex]\displaystyle\frac{1}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\displaystyle\frac{1}{2}x+b[/tex]

Now, to solve for the y-intercept, plug in the point (6,4) and solve for b:

[tex]4=\displaystyle\frac{1}{2}(6)+b\\\\4=3+b\\b=1[/tex]

Therefore, the y-intercept of the line is 1. Plug this back into [tex]y=\displaystyle\frac{1}{2}x+b[/tex]:

[tex]y=\displaystyle\frac{1}{2}x+1[/tex]

I hope this helps!

Answer:

solution,

= 2{4×2+1}

=2{8+1}

=2×9

=18

Step-by-step explanation:

This is the solution

Answer:

18

Step-by-step explanation:

[tex]2(4(9 - 7) + 1)[/tex]

[tex]2(4 \times 2 + 1)[/tex]

[tex]2( 8 + 1)[/tex]

[tex]2 \times 9[/tex]

[tex] = 18[/tex]

Let's solve for b first.

Since b and 147 are opposite, b is also equal to 147 degrees.

b=147

Since c and 147 are supplementary angles, they sum to 180 degrees.

c+147 = 180

Subtract 147 from both sides

c = 33

I'd go for c , x is greater than -3

Step-by-step explanation:

how many times is the money of the elder brother ?

this is the same to ask "how many times do I need to add the money of the younger brother to get the money off the older brother ?"

this is simply done by division : how many times do 56 fit into 280 ?

280 / 56 = 5

so, the elder brother has 5 times the money of the younger brother.

Answer:

56+56+56+56+56

hence

5 times

Step-by-step explanation:

what do you mean lf speed is not given what we have tofind

Answer:

v = d/t, perhaps.

Step-by-step explanation:

Velocity (speed) is defined as distance traveled divided by the time it takes to travel that distance.

This gives an average speed.  For example, I'll be taking a trip tomorrow of about 150 miles.  If it takes me 3 hours, my average speed is v = 150/3 = 50 miles per hour.

That does not mean my speed is constantly 50 miles per hour; I sometimes go slower than that (maybe even stopping for red lights!), and sometimes I'll be going faster than that.

A lot of school math problems assume a constant speed.
