Find the slope the line passes through (-1,7) and (5,-12)

Answer:its 4/5

Step-by-step explanation:

Answer:

Question 9) [tex]y=\frac{-3}{2}x+2 \\\\[/tex]

Question 10) [tex]y=-x-6\\[/tex]

Step-by-step explanation:

Well there are two methods of determining an equation of line

Method 1 (Using the slope-intercept form):

[tex]y=mx+b[/tex]

This method is mostly used when the y-intercept also known as b is given and the slope also known as m is given

Method 2 (Using the point-slope form):

[tex]y-y_1=m(x-x_1)\\[/tex]

This method is used when a point is given also known as (x1 , y1) and the slope is given which is denoted by m.

Since in Question 9 there is no y-intercept given only two points we will use the second method so here goes,

Q9)

Two points are  (0 , 2) and (4 , -4) first step to find out the equation of line is to calculate the slope which is as follows:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-4-2}{4-0} \\\\m=\frac{-6}{4}\\\\m=-3/2 \\[/tex]

Now we have our slope which is m = -3/2 now since we have two points we can use any point in the point-slope form equation because both of these points lie on the line hence satisfying the desired equation that we need so we select the point (0 , 2) [YOU CAN TRY OUT FINDING THE EQUATION OF LINE BY USING THE OTHER POINT THE ANSWERS WOULD BE SAME]

so now we have the point (0 , 2) and value of m = -3/2

[tex]y-y_1=m(x-x_1)\\y-2=\frac{-3}{2}(x-0)\\\\y-2=\frac{-3}{2}x\\\\y=\frac{-3}{2}x+2\\\\[/tex]

Question 10)

Two points are (-2 , -4) and (-3 , -3) we use the same method as shown above,

First step calculate the slope:

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

now we insert the value of m = -1 and take any point of the two points that are given, we select the first point (-2 , -4)

[tex]y-y_1=m(x-x_1)\\y-(-4)=(-1)(x-(-2))\\y+4=(-1)(x+2)\\y+4=-x-2\\y=-x-2-4\\y=-x-6\\[/tex]

Answer:

8/10 or 4/5 (simplified)

Step-by-step explanation:

3/5      >      6/10   (x2 by numerator and denominator to match with 7/10)

6/10 + 7/10 = 13/10

13/10 - 1/2      >      13/10 - 5/10 = 8/10

8/10 or 4/5 (simplified)

-6

Answer:

x = 22

Step-by-step explanation:

Okay since they give you the measurement of 96 degrees and the lines are parallel, this means that 6x - 36 equals 96 degrees. However we are trying to find out what the variable x equals so we are going to put 6x - 36 and 96 degrees into a equation:

6x - 36 = 96

Now we are going to get all variables on one side of the equal sign and all numbers on the other, starting with adding 36 to both sides of the equal sign.

6x - 36 = 96

   + 36   +36

So now the equation looks like this:

6x = 132

Now we are going to segregate the variable x from 6x by dividing 6x by 6 and what you do to one side of the equal sign you do to the other:

6x/6 = 132/6

to equal:

x = 22

Now to check our work we are going to replace the variable x with 22 into the equation:

6x - 36 = 96 Now 6(22) - 36 = 96

132 - 36 = 96

96 = 96

I hope this helps you!!

Answer: f(-2) = -26

Step-by-step explanation:

Substitute -2 in x, it would look like:

8(-2) - 10

-16 - 10

= -26

Answer: (3 + 8i) + (7 -- 2i) - (6 - 5i) = 4 + 15i

Answer:

-4.5

Step-by-step explanation:

-12-3x=x+6

-4x=18

x=-4.5

Answer:

-4.5=x

Step-by-step explanation:

First you would distribute the -3 to the 4 and x inside the parentheses

It would be -3 x 4= -12

Then  -3 x X= -3x

So your equation would now be -12+ -3x = x + 6

Now you add  3x to the -3x to cancel it out and then add it to the x

So your equation now looks like -12=4x +6

Then you subtract 6 from the 6 to cancel it out and add it to the -12

Now your equation looks like -18=4x

Then you divide 4 from the 4x to cancel it out and then divide 4 from the -18

Finally you have  -4.5=x

I'm unsure if this is correct but hopefully this helps :)

Answer:

27x+49

Step-by-step explanation:

1. Start by distributing the 5 to 6x+9. This means to multiply 6x and +9 by 5.

6x times 5 = 30x

5 x 9 = 45.

5(6x+9) simplifies to 30x+45

2. Rewrite the expression as 30x+45-3x+4

3. Combine like terms.

30x - 3x = 27x

45 + 4 = 49

27x+49

Answer:

$360

Step-by-step explanation:

Calculation for what would be the total cost of next month's order

First step is to calculate how much they paid per the two cases of printer papers

Two cases of printer paper=$48 /2

Two cases of printer paper=$24 per case

Second step is to calculate the cost of each package of printer paper

Cost of each package of printer paper=$24/12 packages of paper

Cost of each package of printer paper=$2

Last step is to calculate the total cost of next month's order

Total cost=180 packages*$2

Total cost=$360

Therefore what would be the total cost of next month's order is $360
