Determine the slope between (4, 2) and (-3, 5) ~hurry please~
SpyIntel [72]

Answer:

A.-3/7

Step-by-step explanation:

the slope formula is

m = (y2 - y1) / (x2-x1)

The point (4, 2) is (x1, y1) and the point (-3, 5) is (x2, y2). Now you have to substitute in the slope formula:

m = (5 - 2) / (-3 - 4)

m = 3 / -7

m = -3/7

Find the solution set (x,y,z) of the system:<br> 3x-2y+4z=6<br> 2y-3z=20<br> 6z=12
gizmo_the_mogwai [7]

Answer:

The solution is x = 8, y = 13 and z = 2.

Step-by-step explanation:

We are given a system of equations with the variables x, y, and z from which we have to solve for x, y, and z.

The equations are

3x - 2y + 4z = 6 ........ (1)

2y - 3z = 20 .......... (2)

6z = 12 ......... (3)

Now, from equation (3),  we get z = 2.

Now, putting z = 2 in equation (2) we get

2y = 20 + 6 = 26  

⇒ y = 13

Now, from equation (1), putting y = 13 and z = 2, we get  

3x = 6 - (4 × 2) + (2 × 13) = 24

⇒ x = 8

So the solution is x = 8, y = 13 and z = 2. (Answer)

-(-5 - 6x) = 4 (5x +3)
tatiyna

-(-5 - 6x) = 4 (5x +3)

Pretend that there is a -1 in front of the first bracket

-1(-5-6x)= 4(5x+3)

Mutiply the first bracket by -1

(-1)(-5)(-1)(-6x)= 5+6x

Mutiply the second bracket by 4

(4)(5x)(4)(3)= 20x+12

5+6x= 20x+12

move 20x to the other side

5+6x-20x= 20x-20x+12

5+6x-20x= 12

5-14x= 12

move 5 to the other side

sign changes from +5 to -5.

5-5-14x= 12-5

-14x=7

divide by -14

-14x/-14= 7/-14

x= -1/2

Answer: x= -1/2

After observing this pattern, Amira made a conjecture for the next number in the pattern. 4, 12, 36, 108, 324, …
Alinara [238K]
First, lets observe this pattern.
We can notice that each number when multiplied by 3 gives the following number as:
4 x 3 = 12
12 x 3 = 36
36 x 3 = 108
108 x 3 = 324

Based on this, the next number in the pattern will be: 
324 x 3 = 972

The right choice is:
c. 972

Find the value of b/2a+b, when a=5 and b=-2​
Murrr4er [49]

Answer:

-\frac{1}{4} or -0.25

Step-by-step explanation:

\frac{b}{2a+b}

Plug in a=5 and b=-2

\frac{-2}{2(5)+(-2)}=

\frac{-2}{10-2}=

\frac{-2}{8}=

-\frac{1}{4} or -0.25
