Answer:

  ∠7 = 51°

  ∠8 = 129°

Step-by-step explanation:

All of the obtuse angles are congruent, as are all of the acute angles. The acute and obtuse angles are supplementary.

  ∠8 = ∠1 = 129°

  ∠7 = 180° -129° = 51°

_____

Additional comment

Technically, angles 1 and 8 are called "alternate exterior angles." As such, they are congruent. Angles 7 and 8 form a "linear pair." As such, they are supplementary.

Answer:

Step-by-step explanation:

Every triangle's angles MUST add up to 180. Therefore, 43 + 43 + (6-8x) must be equal to 180. So:

43 + 43 + (6 - 8x) = 180

86 + (6 - 8x) = 180

6 - 8x = 94

-8x = 88

x = -11

X=11 i am not sure about it

Find the sum 14+8+2+...+(−274)+(−280)

Answers

Answer:

Sn=−6650

Step-by-step explanation:

Given the arithmetic sequence:
14+8+2+.....+(-274)+(-280)
Determine the sum.
Sum of Arithmetic sequence formula:
Sn =((a1+an)/2)n
Arithmetic sequence formula:
An=A1+(n-1)d
Solution:
1 st we must determine the common difference and number of terms. To find for the common difference,we subtract a2 by a1
Common difference: 8-14
Common difference: -6

Now we solve for the number of terms by using the formula for arithmetic sequence:
An=A1 +(n-1)-6
-280=14+(n-1)-6
-280=14-6n+6
-280=20-6n
-280-20=-6n
-300=-6n
n=40

Now we can solve for the sum of the arithmetic sequence.

Sn=((a1+an)/2)n
Sn=((14+ -280)/3)50
Sn= (-266/2)50
Sn=(-133)50
Sn= -6,650
Final answer:
-6,650

Step-by-step explanation:

The first equation of System 2 is the first equation of System 1.

The second equation has an x-coefficient of (A-L). The coefficients of x in System 1 are A and L, so (A-L) is their difference. The second equation of System 2 is the difference of the equations in System 1.

c. y = 11.7 + 1.02x
d. y = 2.81 + 1.35x
e. y = -47.3 + 2.02x

Answers

Answer:

The answer is "choice c".

Step-by-step explanation:

Below, we shall find the line equation, dissociation for both the management's behavior and achievement.

Here, attitudes are the response variable while performance seems to be the predictor as attitude is achievement dependant.

If Y indicates the attitude while X relates to workers' performance.

Let's describe the data like:

[tex]y=a+bx+e[/tex]

Now we get the estimates of e via the least quadratic method, – i.e., by reducing the number of segments.

[tex]S=\sum e_{i}^{2}=\sum {(y_{i}-a-bx_{i})^{2}}[/tex]

minimize S to obtain the estimates of a and b as:

[tex]\hat{b}=\frac{\sum{(y_{i}-\bar{y})(x_{i}-\bar{x})}}{\sum{(x_{i}-\bar{x})^{2}}}\\\\\hat{a}=\bar{y}-\hat{b}\bar{x}[/tex]

So,

[tex]a=11.7b=1.02[/tex]

Equation:

[tex]Y=11.7+1.02x[/tex]

can anybody help with this question or at least help me solve one thanks !!!!!

Answers

Answer:

Step-by-step explanation:

1) the triangle on the right is half of an equilateral one, so the minor leg is 9

the left one has the two legs congruent

so we have

2x^2 = 81

x^2 = 81/2

x = 9/√2 = 9/2 √2 (at the numerator)

2) the top triangle has the congruents leg

hypotenuse^2 = 2(6√6)^2

hypotenuse^2 = 2(216)

hypotneuse^2 = 432

hypotenuse = √2^4 * 3^2 * 3

hypotenuse = 12√3

the triangle in the bottom is half of the an equilateral one, so

x = 12√3 * 2 = 24√3

3) the left triangle has congruent legs

7^2 = leg^2 + leg^2

49 = 2leg^2

leg^2 = 49/2

leg = 7/√2 = (7√2)/2

the right triangle is half of an equilateral one

x = 7√2/2 * √3 =  7/2 √6 (at the numerator)

4) the rifht triangle has two congruent legs

hy^2= 2(7√6)^2

hy^2 = 2(294)

hy^2 = 588

hy = √2^2 * 7^2* 3

hy = 14√3

the triangle on the left is half of an equilteral one: so

x = 14

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope = -7+8/1

slope=1

You can see the values of x and f(x) from the given table.

An ordered pairs is in the form of (x, f(x)).

By x-intercept definition;

at x =2

⇒ f(x) = 0

Therefore,  the x-intercept of the continuous function shown in the table is, (2, 0)

Answer:

3.5 °C

Step-by-step explanation:

To find the answer multiply 3 and 7 to get the sum of the temperatures in the first seven days.

        3 x 7 = 21

Add 21 and 8 together to get the sum of the temperatures in the first 8 days.

        21 + 8 =29

Divide 29 by 8 to get the mean temperature for the first eight days.

       29 ÷ 8 = 3.5

if the coordinates are ( -1 , 5) and moved 9 units to the left what is the final answer?

Answers

Answer:

Directions: Write the new coordinates for each point or figure.

Sample Question:

Point F has the coordinates (-9,6). What are the coordinates of its image point after the translation of six units down and three units to the left?

Answer:

The coordinates of its image point after the translation are (-12, 0).

Explanation: When you look at an ordered pair the x number comes first, followed by the y number (x,y). Moving a point left or right changes the x number. Moving a point up or down changes the y number. Left and down require subtraction, while right and up require addition. In the sample, we had to go 3 units to the left, -9 - 3 = -12. We also had to go 6 units down, so 6 - 6 = 0.

Point Q has the coordinates (9,5). What are the coordinates of its image point after a translation of six units up and three units to the right?

Point P has the coordinates (3,4). What are the coordinates of its image point after a translation of 8 units down and 5 units to the left?

Point Z has the coordinates (10,7). What are the coordinates of its image point after a translation of six units down and three units to the right?
