2. ∵triangle ADB is congurent to 2. by S.S.S axiom

  ADC

Answer:

AD cuts BC at I => I is the midpoint of BC => BI = CI

ΔAIB and ΔAIC have:

AB = AC

BI = CI

m∠ABC = m∠ACB ( because ΔABC is a  isosceles triangle)

=> ΔAIB ≅ ΔAIC (sas)

=> m∠BAD = m∠CAD

ΔADB and ΔADC have:

m∠BAD = m∠CAD

AB = AC

AD is the common edge

=> ΔADB ≅ ΔADC (sas)

What is the equation of the circle with center (16, - 12) and a radius of 5

Answers

Answer:

x^2+y^2-32x+24y+375=0

Step-by-step explanation:

Equation of circle with given centre (h,k) and radius=r is

(x-h)^2+(y-k)^2=r^2

Given centre are=(16, - 12) and radius= 5

So equation of circle=

(x-16)^2+(y- -12)^2=5^2

x^2-32x+256+y^2+24y+144=25

x^2+y^2-32x+24y+375=0

Alonso brings \$21$21dollar sign, 21 to the market to buy eggs and avocados. He gets eggs that cost \$2.50$2.50dollar sign, 2, point, 50. Then, he notices that the store only sells avocados in bags of 333 for \$5$5dollar sign, 5. He wants to buy as many avocados as he can with his remaining money. Let BBB represent the number of bags of avocados that Alonso buys.

Answers

Answer:

B ≤ 3.7

Step-by-step explanation:

Total money with Alonso = $21

Cost of Eggs = $2.50

Cost of Avocados in bags of 3 = $5

Let

B = number of bags of avocados that Alonso buys.

The inequality is:

Cost of Eggs + Cost of Avocados in bags of 3 ≤ Total money with Alonso

2.50 + 5B ≤ 21

5B ≤ 21 - 2.50

5B ≤ 18.5

B ≤ 18.5/5

B ≤ 3.7

The number of bags of avocados Alonso bought can be represented by B ≤ 3.7

Answer:

1) The inequality that describes this scenario is 2.50+5B≤21

2) Alonso can afford at most 9 avocados.

If you have a positive x coordinate and a negative y coordinate (2,-3) and you have to reflect it across the x axis is the -3 going to stay the same or become positive? If you could answer the question fast I would be grateful.

Answers

The -3 would become positive.

Step-by-step explanation:

When reflecting over the x or y-axis, the x-coordinate and y-coordinate will always flip to it's opposite.

Adjust the window so you can find all of the points of intersection for the system of equations. What are the roots of the original polynomial equation? Check all that apply. –6 0 6 –4 3 8

Answers

Answer:

Your answer would be 6, -4, and 3

Step-by-step explanation:

The roots of the original polynomial equation are 6, -4 and 3

How to determine the root of the polynomial?

The polynomial equation is given as:

P(x) = (x - 6)(x + 4)(x - 3)

Set the polynomial to 0

(x - 6)(x + 4)(x - 3) = 0

Split the equation

(x - 6) = 0, (x + 4) = 0 and (x - 3) = 0

Solve for x in each split

x = 6, x = -4 and x = 3

Hence, the roots of the original polynomial equation are 6, -4 and 3

A line is defined by the equation y=2/3x-8. The line passes through a point whose y- coordinate is 0. What is the x-coordinates of this point?

Answers

Answer:

12

Step-by-step explanation:

Equation of the line:

              y = [tex]\frac{2}{3} x[/tex] - 8 ;

In slope intercept format, the equation of a line is :

          y = mx + c

If the y-coordinate is 0;

          0 =  [tex]\frac{2}{3} x[/tex] - 8

Add 8 to both sides;

        8 =  [tex]\frac{2}{3} x[/tex]

        24 = 2x

         x = 12

The x coordinate when y= 0 is 12.

Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.

y = 3x −24y = 3x −24

y = 3x + 24

y = -3x + 24

y = -3x - 24

Answers

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8

Here I will explain you friend
So we know the exterior angle is 127
I am marking this triangle ABC
So 127+angle B=180( Linear pair)
So angle B = 180-127
Angle B =53
Also in this question it is AB = AC
So it is an isosceles triangle
So angle B = Angle X ( angles opposite to the equal side of the triangle are also equal)
So Answer is x =53
