Answer:

-1.25x+2

Step-by-step explanation:

x intercept = 2.5

y intercept = 2

0-y intercept/x intercept-0 = m

0-2.5/2-0 = -1.25

Equation form:

y = m*x+b where b is  the y intercept.

m = -1.25

c = 2

To put it all together,

y = -1.25x+2

What is the perimeter of trapezoid JKLM? j -7,4 k -4,4 m -8,3 l -2,3
kompoz [17]
Check the picture below.

you can pretty much just count off the grid the units for JK and MI.

now, let's check how long are KI and JM

\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
K&({{ -4}}\quad ,&{{ 4}})\quad 
%  (c,d)
I&({{ -2}}\quad ,&{{ 3}})
\end{array}\qquad 
%  distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
KI=\sqrt{[-2-(-4)]^2+[3-4]^2}\implies KI=\sqrt{(-2+4)^2+(3-4)^2}
\\\\\\
KI=\sqrt{2^2+(-1)^2}\implies KI=\sqrt{4+1}\implies \boxed{KI=\sqrt{5}}\\\\
-------------------------------

\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
J&({{ -7}}\quad ,&{{ 4}})\quad 
%  (c,d)
M&({{ -8}}\quad ,&{{ 3}})
\end{array}\qquad 
%  distance value
\\\\\\
JM=\sqrt{[-8-(-7)]^2+[3-4]^2}\implies JM=\sqrt{(-8+7)^2+(3-4)^2}
\\\\\\
JM=\sqrt{(-1)^2+(-1)^2}\implies \boxed{JM=\sqrt{2}}

so, add all sides, and that's the perimeter of the trapezoid.

HEEEEELP PLEASE need help with some math work
gizmo_the_mogwai [7]

Option B:

The value of x is 13 because corresponding angles are congruent.

Solution:

In the given figure line k is parallel to line n, and line p intersects line q at a point located on line n.

Given m∠6 = (2x + 28)° and m∠11 = (6x – 24)°

To find which statement is true for the given details.

Option A: The value of x is 13 because adjacent angles are congruent.

∠6 and ∠11 are not adjacent angles.

Therefore the given statement is false.

Option B: The value of x is 13 because corresponding angles are congruent.

∠6 and ∠11 are corresponding angles.

If two parallel lines cut by a transversal, then the corresponding angles are congruent.

Therefore, m∠6 = m∠11

(2x + 28)° = (6x – 24)°

2x° + 28° = 6x° – 24°

24° + 28° = 6x° – 2x°

52° = 4x°

x = 13°

Therefore the given statement is true.

Option C: The value of x is 55 because adjacent angles are supplementary.

∠6 and ∠11 are not adjacent angles.

Therefore the given statement is false.

Option D: The value of x is 55 because corresponding angles are supplementary.

Corresponding angles are congruent not supplementary.

Therefore the given statement is false.

Option B is correct.

The value of x is 13 because corresponding angles are congruent.

You buy a total of 25 burgers and tacos for $67.50. The burgers cost $3.50 each and the tacos cost $2.25 each. Find the number o
Ahat [919]

Answer: you bought 9 burgers and 16 tacos

Step-by-step explanation:

Let x represent the number of burgers that you bought.

Let y represent the number of tacos that you bought.

You buy a total of 25 burgers and tacos. It means that

x + y = 25

The burgers cost $3.50 each and the tacos cost $2.25 each. The total cost of the burgers and tacos that you bought is $67.50. It means that

3.5x + 2.25y = 67.5- - - - - - - - - - - - 1

Substituting x = 25 - y into 1, it becomes

3.5(25 - y) + 2.25y = 67.5

87.5 - 3.5y + 2.25y = 67.5

- 3.5y + 2.25y = 67.5 - 87.5

- 1.25y = - 20

y = - 20/ - 1.25

y = 16

x = 25 - y = 25 - 16

x = 9

14x - 9 + 8x + 3 = 9x - 8 - 3x - 14<br> One Solution<br> Infinitely Many Solutions<br> No Solution
Oliga [24]

Answer:

\large\boxed{\text{One solution.}}

14x - 9 + 8x + 3 = 9x - 8 - 3x - 14

Combine like terms:

14x + 8x - 9 + 3 = 9x - 3x - 8 - 14

22x - 6 = 6x - 22

Subtract 6x from both sides:

22x - 6x - 6 = 6x - 6x - 22

16x - 6 = -22

Add 6 to both sides:

16x - 6 + 6 = -22 + 6

16x = -16

Divide both sides by 16:

16x/16 = -16/16

x = -1. There is only one solution to this equation.
