Answer:

It is growth and the percentage increase is 46%

Step-by-step explanation:

The general form of an exponential function is;

Y = I(1 + r)^n

where Y is the present value, I is the initial, r is the growth or decay ratio, n is the number of times

To know if an exponential function is growth or decay, we need to know the repeating factor

If repeating factor is greater than 1, we have growth, if otherwise we have decay (less than 1).

As we can see in this case, we have r greater than 2, so what we have is growth

To get the percentage increase since it is growth, we equate;

1.46 = 1 + r

r = 1.46-1

r = 0.46 which is same as 46%

Answer:

1) b and m

2) m∠8=m∠6

3) 160°

4)x=60°

Step-by-step explanation:

1) all straight lines sum to 180°

subtract the angles given from 180°

the other angle for b is 25°, while the other angle for m is 155°

so we can see that the angles for both lines are the same, hence they are parallel.

2) ∠8 should be the same as ∠6, ∠10 should be the same as ∠3, ∠7 same as ∠5 and ∠9 same as ∠4

in the options we are only given '∠8 should be the same as ∠6' as the correct answer, so we take that.

3) from the image we can see that both horizontal lines are parallel to each other, so both angles on the lines should be same, so ∠CET would be (2x-16)°

(2x-16)°+(7x+20)°=180°

we get x=20(nearest whole number)

∠CED=7x+20=7(20)+20=160°

4) since we need to show that they are parallel,

(2x+30)°=(4x-90)°

2x-4x=-90-30

-2x=-120

x=60

we then plug the x value into the two equations, in which we get 150° for both the angles [2(60)+30=4(60)-90] ⇒ (150=150)

I hope u understand it the way I put it.

Answer:

3 male teachers didn't have sugar

Step-by-step explanation:

total number of male teachers = 3/5 x 20 = 12

3/4 of teachers have sugar, which is 15

3/5 of 15 = 9 (number of males who had sugar)

total number of males (12) minus number who had sugar (9) equals number of males who didn't have sugar (3)

Answer:

the sides of the air hockey can be used as parallel lines.

m° = angles on a straight line add up to 180. 180 - 64 = 116. 116/2 = 58°

m = 58°

the 64° given is an alternate angle to X.

X = 64°

Answer:

Step-by-step explanation:

65+86+105=256

360-256=104   1=104

85+75+85=245

360-245=115  2=115

92+92+88=272

360-272=88 3=88

74+106+106=286

360-286=74 4=74

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

Given

[tex]2x + 4y = -2[/tex]

[tex]-4x + y = -14[/tex]

Required

Is (4,-2) a possible solution?

In (4,-2)

[tex]x = 4[/tex]

[tex]y = -2[/tex]

Substitute [tex]x = 4[/tex] and [tex]y = -2[/tex] in: [tex]2x + 4y = -2[/tex]

[tex]2(4) + 4(-2) = -2[/tex]

Open all brackets

[tex]2*4 - 4*2 = -2[/tex]

[tex]8 - 8 = -2[/tex]

[tex]0 \ne -2[/tex]

The above expression shows that (4,-2) is not a solution and there is no need to check for the second equation.

negative eight.

Step-by-step explanation:

The absolute value of -8 is 8, the opposite of that is -8.

The opposite of the absolute value of negative eight is 8.

Now, given statement is;

''The opposite of the absolute value of negative eight''.

We have to find value of given written expression.

What is Absolute value?

The absolute value or modulus of a number x is the value of x without any sign either negative or positive.

Now,

The absolute value of negative eight is,

⇒ l -8 l = 8

And, The opposite of the absolute value of negative eight ( 8 ) is,

⇒ -8

Hence, The opposite of the absolute value of negative eight is 8.

Answer:

  (a) (6x -3) +(2x -6) +x = 180

  (b) m∠L = 123°

     m∠M = 36°

     m∠N = 21°

Step-by-step explanation:

a) The sum of angle measures (in degrees) is 180°. The equation reflects this fact:

  (6x -3) +(2x -6) +x = 180

__

b) The equation simplifies to ...

  9x -9 = 180

  x -1 = 20 . . . . . divide by 9

  x = 21 . . . . . . . .add 1

Then the degree measures are ...

  m∠L = (6x -3)° = (6·21 -3)° = 123°

  m∠M = (2x -6)° = (2·21 -6)° = 36°

  m∠N = x° = 21°
