Answer:

The value of AM = 43

Step-by-step explanation:

As point M is the midpoint of AB, so

AB = AM + BMAM = BM

Given

AB = 8x - 50

AM = 2x + 9

so substituting AB = 8x - 50 and AM = 2x + 9 in the equation AB = AM + BM

AB = AM + BM

8x - 50 = 2x + 9 + BM

8x - 2x - 50 - 9 = BM

6x - 50 = BM

Thus,

BM = 6x - 59

As

AM = BM

so substituting AM = 2x + 9 and BM = 6x - 59 in the equation AM = BM

2x + 9 = 6x - 59

switch sides

6x - 59 = 2x + 9

subtract 2x from both sides

6x - 2x - 59 = 2x + 9 - 2x

4x - 59 = 9

add 59 to both sides

4x - 59 + 59 = 9 + 59

4x = 68

divide both sides by 4

4x/4 = 68/4

x = 17

Thus, the value of x = 17

Therefore, the value of AM will be:

AM = 2x + 9 = 2(17) + 9 = 34 + 9 = 43

Hence, the value of AM = 43

Verification:

AM = BM

2x + 9 = 6x - 59

2(17) + 9 = 6(17) - 59

34 + 9 = 102 - 59

43 = 43

and

AB = 8x - 50 = 8(17) - 50 = 86

Correct the error. What should the line actually be?

Step-by-step explanation:

Given: [tex]f(x)=4(2)^x[/tex], which is an exponential growth function.

To evaluate: f(-3)

Substitute x=-3 in the given function, we get

[tex]f(-3)=4(2)^{-3}\\\\=4(\dfrac{1}{2})^3\ [a^{-n}=\dfrac1{a^n}]\\\\=4\times\dfrac1{2^3}\\\\=4\times\dfrac18\\\\=\dfrac12[/tex]

Tristan and Evan are employees for a company. Tristan is making a salary of $49,000. Evan is earning a salary that is 29% lower than the salary of Tristan. What salary is Evan earning?

Answers

tristan = $49,000
evan=$34790
you can do this two ways:

Find what is 29% of 49,000:
29/100 x 49,000 = 14,210
Then, minus it from 49,000:
49,000-14,210=34790
Evan earns $34790

The second way to do this is by using a multiplier:

First, minus 29 from 100:
100-29=71
Then, convert it to a multiplier by dividing by 100:
71/100=.71
.71 is now your multiplier, multiply this with 49,000:
49,000x.71=34790

You get the same answer as the first method

The square below has an area of x^2+10x+25 square meters. What expression represents the length of one side of the square?

Answers

Answer:

(x+5) m

Step-by-step explanation:

Given that,

The area of a square shape, [tex]x^2+10x+25[/tex]

We need to find the expression for the length of one side of the square.

The area of a square shaped object is given by :

[tex]s=x^2[/tex]

x is side of the square

[tex]s=\sqrt{A} \\\\s^2=x^2+10x+25\\\\=x^2+5x+5x+25\\\\=x(x+5)+5(x+5)\\\\=(x+5)^2\\\\s=(x+5)[/tex]

So, the sides of the square is (x+5) m.

2# Cierra is keeping track of the amount of money in her lunch account each week. She writes the equation A = -6w + 40. What number represents the rate of change?

Answers

Answer:

The rate of change is the slope

In this case

m=2d+50 is a slope intercept equation.

where m is where the y would be

the 2 which is originally where the slope or (m) would be

the d for the (x)

and 50 for the y intercpet or (b)

so

#1=2

The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.

Answer: If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Step-by-step explanation: So we know that two triangles are congruent if all of their sides are the same-- so side, side, side. We also know they are congruent if we have a side and then an angle between the sides and then another side that is congruent-- so side, angle, side.

Answer:

  (c)  f(x) = -3x^2 +x

Step-by-step explanation:

Points either side of (0, 0) have lower y-values, so you know the parabola opens downward. This eliminates the first two choices.

Trying one of the other points in the one of the remaining equations tells you which equation works.

For example, usint (-1, -4) in the third choice, we get ...

  f(-1) = -3(-1)^2 +(-1) = -3 -1 = -4 . . . . . matches point (-1, -4)

The correct function is the third choice:

  f(x) = -3x^2 +x

Which of the coordinate points below will fall on a line where the constant of proportionality is 1/3? Select all that apply.

A) (5,8)

B) (3,1)

C) (9,3)

D) (12,4)

E) (18,6)

Answers

Answer:

The answer is B,C,D and E

The points that show the proportionality rate 1/3 are (3, 1), (9, 3), (12, 4) and (18, 6).

What is proportional relationship?

A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.

We have constant of proportionality is 1/3.

And the proportionality is represented as x/y = k, where x and y are two expressions and k is constant.

So, x / y = 1/3

A) (5,8)

x/y = 5/8 ≠ 1/3

B) (3,1)

x/y = 1/3

C) (9,3)

x/y = 3/9 = 1/3

D) (12,4)

x/y = 4/12 = 1/3

E) (18,6)

x/y = 6/18 = 1/3

Therefore, B, C, D and E are the answers.
