B. 0
C. 3
D. 2

Answer:

Final equation: y = -7x -19

Step-by-step explanation:

You are looking for slope intercept correct?

Formula: y = mx + B

Y = y-value of point ( coordinates )

M = slope

X = x - value of point ( coordinates )

B = Y - intercept

Equation:

2 = -7(-3) + B

2 = 21 + B

-21 = -21 = B

------------------

-19 = B

Final equation: y = -7x -19

Unless if it asks you to plug back the numbers for anything else then you do that but this is how you get slope intercept.

Answer:

AB=1

Step-by-step explanation:

Colinear means all points are on the same line. We need to find the measure of AB.

Using the segment addition postulate,

ab+bc=ac

Subsitue this for our known values

[tex]2x + 15 + 9 = x + 17[/tex]

Solve for x

[tex]2x + 24 = x + 17[/tex]

[tex]x + 24 = 17[/tex]

[tex]x = - 7[/tex]

Plug this in for AB

[tex]2( - 7) + 15 = 1[/tex]

Answer:

The answer is 2. It is the commutative property of addition. This states that the order of numbers does not matter in addition or multiplication. As long as all the numbers are there, it will give the same answer :)

Answer:

A. step 1

Step-by-step explanation:

I think its A , because a negative plus a negative is a postive

Answer:

step 2 is the incorrect step

Answer:

y = -58

Step-by-step explanation:

You have to isolate the y:

-2+y/10 = -6

First step, multiply both sides by 10:

-2+y = -60

Second step, add 2 on both sides:

y = -58

It's done!

Answer:

-2=-40/10=-6

Step-by-step explanation:

-2/10 alone is -0.2.

Using PEMDAS your problem should look more like, (-2)+((y)÷10)=

Using this new formula let's start plugging in numbers.

(-2)+((0)÷10)= -2

(-2)+((-1)÷10)= -2.1

(-2)+((-2)÷10)= -2.2

Now there is a pattern, you can calculate or just keep moving up the latter until you reach the desired sum.

After finding the plug-in use PEMDAS to solve.

(-2)+((-40)÷10)=

((-40)÷10)= -4

-4+-2=-6.

So (-2)+((-40)÷10)= -6

Replace x and y’all with the point and solve the equations

1. 2(0.5)+ 4(-6.75) = 1 + -27 = -26

This is true so is an answer.

2. Y = 0.5-7.5 = -7, -7 is not -6.75 so this is not true.

3. 2(-6.75) = 0.5 + 13

13.5 = 13.5

This is true so is also an answer.

4. -6.75 = 0.5(0.5) -7

-6.75 = 0.25-7

This is true so also an answer.

Answers are 1, 3 and 4

Answer:

Equation 1 and 4

Step-by-step explanation:

Point = (x,y) = (0.5,-6.75)

Hence,

x = 0.5 , y = -6.75

Equation 1:

2(0.5) + 4(-6.75) = -26

1 - 27 = -26

-26 = -26

This equation is true for the given point.

Equation 2:

-6.75 = 0.5 - 7.5

-6.75 ≠ -7

The equation is not true for the given point.

Equation 3:

2 (-6.75) = 0.5 + 13

-13.5 ≠ 13.5

The equation is not true for the given point.

Equation 4:

-6.75 = 0.5(0.5) - 7

-6.75 = 0.25 - 7

-6.75 = -6.75

This equation is true for the given point.

Answer:

A rhombus is a geometric figure that lies in a plane. It is defined as a quadrilateral all of whose sides are congruent. It is a special type of parallelogram, and its properties (aside from those properties of parallelograms) include:

Its diagonals divide the figure into 4 congruent triangles.

Its diagonals are perpendicular bisectors of eachother.

If all of a rhombus' angles are right angles, then the rhombus is a square.

Answer:yes it does have perpendicular lines

Step-by-step explanation: Though the times might be confusing, the problem itself is simple addition- if the temperature rises, or goes up, by a certain number, in this case three, you're just going to add that number to the initial number, two.

Answer: d = 39

Solve:

Given

d / 3 = 13

In order to get the value of d, we need to isolate d, which means we should multiply 3 on both sides to delete the 3 on the left-hand side

d / 3 × 3 = 13 × 3

d = 39

Check:

Left-hand side = d / 3 = 39 / 3 = 13

Right-hand side = 13

13 = 13

Hope this helps!! :)

Please let me know if you have any questions

Answer:

39

Step-by-step explanation

so d ÷ 3 = 13

first we want to change these numbers into a fraction so

d ÷ 3 = [tex]\frac{d}3}[/tex]

13 is whole but we can still display it as 13÷1 =[tex]\frac{13}{1}[/tex]

line these up like this

[tex]\frac{d}{3} \frac{13}{1}[/tex]

now cross multiply the numbers that always line up diagonally so 13 and 3

13x3=39

next divide that answer by the number diagonal to the unknwon so 39÷1 = 39

that means d = 39

Step-by-step explanation:

what do you need to do ? draw the line ? or find some intercepts on the x- or y-axis ? or ?

in any case it is important to bring this into the typical line equation form :

y = ax + b

so,

-4x = -1 + y

we leave y alone on one side

y = -4x + 1

to draw the line you need 2 points.

so, let's find some.

one typical choice is x = 0.

then y = -4×0 + 1 = 1

so, P1 = (0, 1)

and then e.g. let's pick x = 1

then y = -4×1 + 1 = -4 + 1 = -3

so, P2 = (1, -3)

there you have it

mark the two points on the coordinate graph, then take a ruler and draw the line all the way from top left to bottom right so that it goes through the two points.
