Answer:

slope =[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope, or [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:

[tex]m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}[/tex]

Thus, the slope is [tex]-\frac{2}{3}[/tex].

Answer:

Greatest common factor of 17

So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!

Step-by-step explanation:

Add and subtract the second term to the expression and factor by grouping.

- (m - 1 )( 7m + 17 )

Answer:

e= -10/9

Step-by-step explanation:

Answer:

e = 10

Step-by-step explanation:

1.) We need to manipulate the equation to get e by itself.

2.) To solve the equation, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e (Combine like terms)

9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)

e + 4 = 14 (Combine like terms)

e + 4 - 4 = 14 - 4 (Subtract 4 from each side)

e = 10 (Combine like terms.

3.) Answer: e = 10.

Now lets check our work. To check your work, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e

9(10) + 4 = 14 + 8(10)

90 + 4 = 14 + 80

94 = 94

By doing those steps we can confirm the answer, e = 10, is true.

Answer:

x^2 - 6x + 9

Step-by-step explanation:

(x-3)^2

(x-3)(x-3)

x^2 -3x -3x + 9

x^2 - 6x + 9

^2 means (x - 3) times itself twice.

(x - 3)(x - 3)             multiplying polynomials- Firsts, Outs, Inners, Lasts (FOIL)

                                 Firsts (x* x)   Outs (x*-3)   Inners (-3 * x)   Lasts (-3*-3)

xx -3x -3x +9            Combine like terms.

      -3x -3x             Adding/subtracting integers- same signs means you add          

                                     and keep the sign.

Answer:

Where is it?

Step-by-step explanation:

Where is the question exactly?

Answer:

x=1 and y= 5[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

To solve this, lets take the first equation and find the x value.

Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.

5x+4y=16

-5x       -5x

4y=-5x+16

÷4   ÷4  ÷4

y=[tex]\frac{-5}{4}[/tex]+4

or

y=-1[tex]\frac{1}{4}[/tex]+4

or

y= 5[tex]\frac{1}{4}[/tex]

Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:

5x+4([tex]\frac{-5}{4}[/tex]+4)=16

5x-5+16=16

5x+11=16

    -11 -11

5x=5

÷5 ÷5

x=1 and y= 5[tex]\frac{1}{4}[/tex]

Answer:

download photo math you can take pictures of math problems and will solve them.

Angle 1 and 2 are equal because of correspondence angle

so , (78-2x) = (89-3x)

x = 89 - 78

x = 11

hence angle 1 = ( 78 - 2*11) = 56

and angle 2 = ( 89-3*11) = 56

So, both of angle is 56

Answer:

576

Step-by-step explanation:

f(2) = 4f(1) = 4*9 = 36

f(3) = 4f(2) = 4 * 36 = 144

f(3) = 4f(3) = 4 * 144 = 576

【Rep.】The least common multiple of 12 and 24 is 24.

To obtain the least common multiple (lcm) we must do it by simultaneous decomposition.

This method consists of extracting the common and uncommon prime factors, then

Answer:

m = 7

Step-by-step explanation:

21 = m + 14

21 - 14 = m

m = 7

Find the gradient first

m = (y2-y1)/(x2-x1) = 3-(-1)/2 - (-2) = 4/4 = 1

then find the equation of the... slope ._.

y - y1 = m(x - x1)

y - (-2) = 1(x - 3)

y + 2 = x - 3

y =x -3 - 2

y = x - 5

So the equation is y = x - 5

Answer:

I think its gon be 24 guests

Answer:

24 people can be there at most :)

Step-by-step explanation:

$32 divided by 16(guests) is $2

so its $2 per person

so 48$ divided by $2 is 24

So Camille can invite 24 people at the cost of 48$ being her total at most :)
