Answer:

19.95t - $10

Step-by-step explanation:

I think this is the answer but i could be absolutely wrong

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:

117 is the answer of your questions

Step-by-step explanation:

supplement=180

given angle=63

180-63=117

Step-by-step explanation:

y+x-2-6x = y-5x-2

2x+3-x-4 = x-1

5xy+4x-5xy-3 = x

26² - 10² = 676 - 100 = 576

√576 = 24

The height of the Flagpole is, 24 feet.

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

The base length = 10 ft

And, The hypotenuse length = 26 ft

Now, Let height of the Flagpole = x

So, By Pythagoras theorem we get;

⇒ Hypotenuse² = Base² + Perpendicular²

⇒ 26² = 10² + x²

⇒ 676 = 100 + x²

⇒ x² = 676 - 100

⇒ x² = 576

⇒ x = √576

⇒ x = 24 feet

Thus, The height of the Flagpole = 24 feet

Answer:

3.6

Step-by-step explanation:

sorry for the weird looking numbers, I used my mouse to write this

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:

B

Step-by-step explanation:

3(2x-50)=2(8x-7)+4x

6x-150=16x-14+4x

x=136/14

x=9.7=10

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

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.

Answer:

509/561

Alternate form is 0.9073

Step-by-step explanation:

The L.C.M is 561.

561/11 × 2 is 102.

561/17 × 1 is 33

561/3 ×2 is 374

102/561 + 33/561 + 374 /561

= 509/561

Alternate form is 0.9073

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

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.
