A line with what type of slope contains the points (-2, 5) and (-2, 6)?
Answer:
undefined
Step-by-step explanation:
To find the slope
m = ( y2-y1)/(x2-x1)
= ( 6-5)/( -2 - -2)
= (6-5) /(-2+2)
= 1/0
We cannot divide by zero, so the slope is undefined

Solve the right triangle. Round decimal answers to the nearest tenth. I can´t figure out KL and ML.
Answer:
Me to I need that Answer en m<k is 50°
Step-by-step explanation:
The measure of KL is 5.1 unit and the measure of ML is 6.1 unit.
What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given that, MK=8 units, ∠M=40° and ∠K=50°.
We know that, sinθ=Perpendicular/Hypotenuse
Now, sin40°=KL/8
0.6427=KL/8
KL=0.6427×8
KL=5.1 units
sin50°=ML/8
0.7660=ML/8
ML=6.1 units
Therefore, the measure of KL is 5.1 unit and the measure of ML is 6.1 unit.

B B A С E D Answer. D Focus
Complete question :
Kenny is putting a brick border around his irregular shaped garden. Before installing the border, Kenny must
cut the bricks to fit the angles of the garden. Use the given measures to answer the question.
mzA=x
mZB=(5x-5)
m2C =(2x +20)
mZD=(3x-15)
mZE =(4x)
What are the angle measures of each vertex of the garden? Show your work.
Answer:
m<a=36
m<b=175
m<c=92
m<d=93
m<e=144
Step-by-step explanation:
Use the given measures to answer the question. MZA= x mZB = (5x – 5)º M2C = (2x+20)° m_D = (3x –15)° MZE = (4x)
We are given five angles :
Using the sum of interior angle of a regular polygon formula :
180(n - 2) ; where, n = number of sides ;
180(5 - 2) = 180 * 3 = 540°
The sum of the 5 angles should add up to 540°
x + (5x - 5)° + (2x + 20)° + (3x - 15)° + 4x = 540
5 + 20 - 15 + 5x + 2x + 3x + 4x + x = 540
15x = 540
15x = 540
15x = 540
x = 36
mzA= 36°
mZB=(5(36)-5) = 175°
m2C =(2(36) +20) = 92°
mZD=(3(36)-15) = 93°
mZE =(4(36) = 144°

What is the value of x in the equation below?
-12x-(-9)=-15
Answer:
x = 2
Step-by-step explanation:
Due to this being urgent, I'm foregoing the explanation
Answer:
x = 2
Step-by-step explanation:
-12x - (-9) = -15
-12x + 9 = -15
Subtract 9 from both sides
-12x + 9 - 9 = - 15 - 9
-12x = -24
Divide both sides by (-12)
x = -24/-12
x = 2
Does f(x)=x^2-6x+14 have a minimum or maximum?
Answer:
Step-by-step explanation:
So like uhm its maximum cs I said so period
Answer:
It has a minimum in the point (3, 5)
Step-by-step explanation:
A quadratic function always has either a minimum or a maximum - never both. To find out which one, just look at the coefficient at the x^2. If it's positive, it has a minimum (think of its value for very low x - the value gets higher and higher, because x^2 is positive and rising the lower x is - similar for very high xs when x increases - so it must have a smallest point in the middle).
Analogously, if the coefficient at the x^2 is negative, the reasoning above is reversed - so it has to have a highest point.
Because out function has a positive coefficient at x^2 (the coefficient is 1), we know the function has a minimum.
BTW, let's find the minimum. We can rewrite the function as
[tex]f(x) = x^2 - 6x + 14 = x^2 - 6x + 9 + 5 = (x - 3)^2 + 5[/tex]
Notice that you can do that to any quadratic function by analyzing the ratio between coefficient at x^2 and at x.
Now the function is an x^2 function that was moved 5 upwards and 3 to the right. The minimum has to be in x - 3 = 0, so x = 3, and the value is 5!
The minimum is at (3, 5).

Answer:
b=70 degrees
Step-by-step explanation:
a= 8x+6. b= 4x+38
a=b alternate exterior
combine like terms
8x+6=4x+38
Subtract 4x from both sides and 6
4x=32
Divide by 4
x=8
Plug in= 8 for B equation
b= 4(8)+38
b=70 degrees
Answer:
x = 8
m∠B = 70°
Step-by-step explanation:
The alternate exterior angles theorem states that m∠A and m∠B are the same. So,
8x + 6 = 4x + 38
Subtract 6 from both sides.
8x = 4x + 32
Subtract 4x from both sides.
4x = 32
Divide both sides by 4.
x = 8
Now to find the measure of m∠B, substitute x = 32 into 4x + 38.
8 * 4 + 38 =
32+ 38 = 70
m∠B = 70°
Just in case, let's double check our answer. Because m∠A is equal to m∠B, m∠A should be equal to 70.
70 = 8x + 6
70 = 8 * 8 + 6
70 = 64 + 6
70 = 70
Thus, x = 8 and m∠B = 70° is true.
I hope this helps! Feel free to ask any questions!
Four friends shared 3 orders of chicken wings. • Alex ate 5 of an order. ·8· • Chase ate 7 of an order. ·8· • Ella ate 6 of an order. ·8· How much chicken is left for the fourth friend?
Answer: 3/4
Step-by-step explanation:
Amount of chicken ordered = 3
Fraction eaten by Alex = 5/8
Fraction eaten by Chase = 7/8
Fraction eaten by Ella = 6/8
The chicken ate by the three friends will be:
= 5/8 + 7/8 + 6/8
= 18/8
= 2 2/8
= 2 1/4
Now, the chicken left for the forty friend will be:
= 3 - 2 1/4
= 3/4
what is the y-intercept of a slope of 0 that goes through (-5,6)

Step-by-step explanation:
A shop has two offers.
Without a Store card
With a Store card
1
3
off normal prices
45% off normal prices
Laura is going to buy a coat in the shop.
The normal price of the coat is £90
Laura would pay less with a Store card than she would pay without a Store card.
How much less?
can: 3=30
Answer:
We can easily see that 45% is larger than 1/3, so the second option is better, and to calculate it 45 percent of 90 is 40.5, and 1/3rd of 90 is 30, so Laura would pay 49.5 and 60, the 2nd option would have her pay 10.5 dollars less than the 1st option

Help, Please! There is a Simicircle with a diameter of 36mm, what is the area? Use 3.14 for pi
Answer:
28.258mm
Step-by-step explanation:
A semi circle is half of a circle, so we will divide it by 2 after finding the area.
Formula for finding semi circle = pi x radius ÷ 2
Formula for radius = diameter ÷ 2
Radius = 36 ÷ 2 = 18mm
Semi circle = 3.14 or 22/7 x 18 = 56.57
56.57 ÷ 2 = 28.285
Note: I don't have a calculator with me right now, so you might want to consider typing out pi x 18 ÷ 2 on a calculator since my answer might be wrong because the answer has endless decimals.
