2x+y=2

Answers

Answer 1

x = 0

y = 2

Step-by-step explanation:

4x - y = -2

2x + y = 2

-------------- add the equations

6x = 0

x = 0

substitute x in equation 1

0 - y = -2

y = 2

In a right triangle ΔABC, the length of leg AC = 5 ft and the hypotenuse AB = 13 ft. Find:
The length of the angle bisector of angle A

Answers

i think the answer is 2.6 ‍♀️

Answer:

∠A is (5/3)√13

Step-by-step explanation:

The cosine of ∠A is [tex]\frac{AC}{AB}[/tex]  = [tex]\frac{5}{13}[/tex]

The cosine of half of ∠A is given by the half-angle formula:

cos(A/2) = √((1 +cos(A))/2) = √((1 + 5/13)/2) = √(9/13) = 3/√13

The length of the segment b is found from ...

cos(A/2) = 5/b   [adjacent side/hypotenuse]

 ∠ A = 5/cos(A/2) = 5/(3/√13)

∠ A = (5/3)√13

If Needed in decimal form : 6.01

Answer:

x=4 y=-3

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

x−2y=10 ; 6x+3y=15

Step: Solve x −2y= 10for x:

x − 2y + 2y = 10 + 2y (Add 2y to both sides)

x=2y+10

Step: Substitute 2y+10 forx in 6x+3y=15:

6x+3y=15

6x+3y=156(2y+10)+3y=15

15y+60=15 (Simplify both sides of the equation)

15y+60+−60=15+−60 (Add -60 to both sides)

15y=−45

15y/15=−45/15(Divide both sides by 15)

y=−3

Step: Substitute −3 for y inx=2y+10:

x=2y+10

x=(2)(−3)+10

x=4(Simplify both sides of the equation)

What is the effect of removing the outlier 11 from the following data set? (1 point)

{11, 85, 87, 88, 91, 91, 92, 93, 95}

A The mean would increase.
B The median would decrease.
C The interquartile range would increase.
D The median of the lower quartile would stay the same.

Answers

Answer:

A The mean would increase.

Step-by-step explanation:

mean = sum of numbers ÷ how many numbers there are

the mean with the outlier 11:

(11 + 85 + 87 + 88 + 91 + 91 + 92 + 93 + 95) ÷ 9 = 81.4

the mean when removing the outlier 11:

(85 + 87 + 88 + 91 + 91 + 92 + 93 + 95) ÷ 8 = 90.25

the mean has now increased

Step-by-step explanation:

Triangles MNC and RSC are similar because all 3 angles are the same, so the the ratio between each side should be the same.

If NC=12 and SC=6 then triangle MNC is scaled up by 2 from triangle RSC. This means each side of MNC is 2 times bigger than on RSC. So, sense RS=4, we can multiply that by 2 to get MN=8.

Write an equation the describes the line passing through point (0,7) with slope - 7/3

Answers

Answer:

[tex]y=\frac{7}{3}x+7[/tex]

Step-by-step explanation:

[tex]y=mx+b\\\\y=\frac{7}{3}x+b\\ \\7=\frac{7}{3}(0)+b\\ \\7=b\\\\y=\frac{7}{3}x+7[/tex]

For these kinds of problems, the point-slope formula comes in handy.

The point-slope form (y - y1 = m(x - x1) +b) uses the slope and a point given to find the y-intercept, or in this case, the equation of the line.

First, we plug the known #'s into the equation, then solve.

y - 7 = -7/3( x -0)

y - 7 = -7/3x

   +7        +7

y = -7/3x +7

Therefore, the equation of the line is: y = -7/3x + 7

Tell whether the angels are adjacent or vertical. Then find the value of x.

(please show how you solved the problem!)

Answers

Answer:

Angles: adjacent

x = 18

Step-by-step explanation:

Adjacent Angles: angles that border each other to the left/right

Vertical Angles: opposite set of angles that are congruent

Given these definitions, these angles are not only adjacent, but also right angles. Right angles add to 90°.

Thus, 3x + 2x = 90

Step 1: Combine like terms.

[tex]3x + 2x = 90[/tex] [tex]5x = 90[/tex]

Step 2: Divide both sides by 5.

5x ÷ 5 = 90 ÷ 5x = 18

Therefore, the answer is adjacent and x = 18.

it takes me 12 minutes to run 2 kilometers. how long will it take me to run 10000 meters

Step-By-Step Explanation:

1. 12/2= 6 (6 minutes per kilometer)

2. 10000/1000= 10 (10000m is 10km)

3. 10*6= 60min

If this helped, please consider picking this answer as the Brainliest Answer. Thank you!

Answer:

60 minutes or 1 hour

Step-by-step explanation:

Time taken to cover the distance of 2 km = 12 minutes

10000m = 10km

Then time taken to cover the distance of 10 km = 5 x 12 = 60 minutes

I have multiplied 12 with 5 because if we multiply 2km with 5 we will get 10km. So, hope you understood my explanation. If not ask me your doubt in comment.
