PLEASE HELP ASAP!!!!!!!!!!
Isabella solved the following equation:

4x − 2x + 8 = 6(x + 4)

Which step has an incorrect justification?

We know that, Two angles are said to be complementary, if the sum of their measures is 90°.

According to the Question,

⇒ ∠ABD + ∠DBC = 90°

⇒ (2x + 30)° + (3x + 20)° = 90°

⇒ 2x + 30° + 3x + 20° = 90°

⇒ 5x + 50° = 90°

⇒ 5x = 90° - 50°

⇒ 5x = 40°

⇒ x = 40°/5

⇒ x = 8

So, the measure of each angle will be,

⇒ ∠ABD = (2x + 30)°

= 2 × 8 + 30°

= 16 + 30°

= 46°

⇒ ∠DBC = (3x + 20)°

= 3 × 8 + 30°

= 24 + 30°

Answer:

∠DAB = 68

Step-by-step explanation:

∠DAB we need to find this

∠DAB = ∠C (vertically opposite angles are equal)

∠DAB = 68

Step-by-step explanation:

21.

1, 2, 4, 8, 16, 31, ... , ....

by using the formula, we can find :

T7 = [7⁴ - 6(7)³ +23(7)² - 18(7) +24] / 24 =

(2401 - 2058 + 1127 - 126 +24) / 24 =

1368/ 24 = 57

T8 = [8⁴-6(8)³+23(8)²-18(8)+24]/24 =

(4096-3072+1472-144+24)/24 =

2376/ 24 = 99

For point A)[tex]\to \bold{f(x)=(x-8)(x+1)(x+3)=(x^2-7x-8)(x-8)=(x^3-4x^2-29x-24)}[/tex]For point B)

[tex]\to \bold{x^2-x-2=(x-2)(x+1)}\\\\\to \bold{g(x)=\frac{(x-8)(x+1)(x+3)}{(x-2)(x+1)}}[/tex]

Answer:

Part A:

x^3 - 4x^2 - 29x -24

(x + 1)(x - 8)(x + 3)

Part B.

(x + 1)(x - 8)(x + 3) / x^2 - x - 2= (x + 3)(x - 8) / x - 2

g(x)=  (x + 3)(x - 8) / x - 2= y= x - 3

Part C.

x=2.

Answer:

7 quaters and 19 dimes

Step-by-step explanation:

Let say x the numbers of quaters,

2*x+5 the numbers of dimes

In cents,: 25*x+10*(2x+5)=365

25x+20x+50=365

45x=365-50

45x=315

x=7

Number of quaters: 7

Number of dimes: 2*7+5=19

Proof:

7*25+10*19=365

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

4x + y = 1 ( subtract 4x from both sides )

y = - 4x + 1 ← in slope- intercept form

with slope m = - 4 and y- intercept c = 1

Answer:

number is 3

Step-by-step explanation:

let the number be n then the product of 3 and the number is 3n , so

16 = 7 + 3n ( subtract 7 from both sides )

9 = 3n ( divide both sides by 3 )

3 = n

That is the number is 3

Answer:

Step-by-step explanation:

The expanded form of 79 is 70+ 9. To apply the distributive property you rewrite the problem 3(70 + 9) which is the same as (3x70) + (3x9). Next do the multiplication 3x70= 210 + 3x9= 27

Next add the sums: 210 + 27 = 237.

P=R-$10MM

P = ($25MM)-$10MM

P = $15MM

Answer:

Step-by-step explanation:

The balls - multiples of 3 are:

The probability of a multiple of 3 is:

30% probability is in the range 0%-50% so this event is unlikely

Total multiples=3

[tex]\\ \sf\longmapsto P(3)=\dfrac{Multiples\:of\:3}{Total \:balls}[/tex]

[tex]\\ \sf\longmapsto P(3)=\dfrac{3}{10}[/tex]

[tex]\\ \sf\longmapsto P(3)=30\%[/tex]

So it is unlikely to happen.

How to solve -7+7s-3s-5-6-5s

Answer:

add all the rest of the angles, and then subtract the sum from 1080, and that's your ans mate

Answer:

147

Step-by-step explanation:

If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

Answer:

(13,-6)

Step-by-step explanation:

The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.

First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.

Then do the same thing with the y coordinate. And you get -6.

Your endpoint is (13,-6)

Answer:

Step-by-step explanation:

a) Number = x

Multiply it by 3 = 3*x = 3x

Now add 4 to it: 3x + 4

Equation:  

3x +4 = 22

b)

3x + 4 = 22

Subtract 4 from both sides

3x + 4 -4 = 22 - 4

        3x = 18

Divide both sides by 3

3x/3 = 18/3

x = 6

Answer:

Below in bold.

Step-by-step explanation:

The equation is

3x + 4 = 22

3x = 22 - 4 = 18

x = 18/3

x = 6.

Answer:x=11

65.25x + 1063.50= 1781.25

To solve this equation, subtract the rental cost of the bus to get $717.75.

Now the equation should be 65.25x= 717.75

Divide both sides by 65.25, and you should get that x = 11. That’s your finally answer!
