Step-by-step explanation:

If m and n are parallel, then

∠ CBA = ∠ 2 ( alternate angles )

The sum of the 3 angles in a triangle = 180°, thus

∠ 1 + ∠ 2 + ∠ 3 = 180° ( sum of the angles in the triangle )

Answer:

  (a)  y = 1.5·1.3^x

Step-by-step explanation:

Growth is modeled by an exponential function when the base is greater than 1.

There is only one answer choice that models growth. The others all have a base (0.5 or 0.59) that is less than 1, so model decay.

  y = 1.5·1.3^x

The solution to the provided expression using the difference of square formula of algebra is a=1.

The difference of square says, the difference of the square of two terms is equal to the product of their sum and difference. It can be given as,

a^2-b^2=(a+b)(a-b)

The given expression in the problem is,

[tex]15(2a - 2) = 5(a^2 -1)[/tex]

From the property of difference of square, the above equation can be written as,

[tex]15(2a - 2) = 5[(a +1)(a-1)]\\15\times[2(a - 1)] = 5[(a +1)(a-1)][/tex]

Divide both side of the equation with (a-1) as,

[tex]5\times2 = 5(a +1)[/tex]

Divide both side of the equation with number 5 as,

[tex]2 = (a +1)\\a=2-1\\a=1[/tex]

Hence, the solution to the provided expression using the difference of square method of algebra is a=1.

Step-by-step explanation:

Given:

The equation is

[tex]\dfrac{7}{2}n=3n+4[/tex]

To find:

The properties which is not used from the given options.

Solution:

We have,

[tex]\dfrac{7}{2}n=3n+4[/tex]

Using Multiplication Property of Equality, multiply both sides by 2.

[tex]2(\dfrac{7}{2}n)=2(3n+4)[/tex]

[tex]7n=6n+8[/tex]                    (Distributive Property)

Using Subtraction Property of Equality, subtract 6n from both sides.

[tex]7n-6n=6n+8-6n[/tex]

[tex]n=8[/tex]

From the given options only one property is not used, i.e., Zero Product Property.

Therefore, the correct option is D.

Answer:

5 ≤ 2n - 3.6

Step-by-step explanation:

Five is less than or equal to the difference of twice a number n and 3.6

Five is less than or equal to:  5 ≤

twice a number n:  2n

difference of twice a number n and 3.6:  2n - 3.6

Therefore,

5 ≤ 2n - 3.6

Number is n

Twice a number means multiplication

Difference means subtraction

The expression becomes

5<=2n-3

Answer:

a + 55 =180

a=180-55=125

b = 55 alternate angles

c=a=125 alternate angles

e =125. alternate angles

f=b=55

h=f=55 alternate angles

Step-by-step explanation:

(a) < a = 180-55= 125

(b) < b = 180- 125= 55

(c) < c = 189- 55 = 135

(d) < e = 125

(e) < f = 180-125= 55

(f) < h = 55

~

< a and < c are vertical angles.

< a and < b are adjacent angles.

< b and <h are Alternate interior angles.

< f and 55° are Alternate Exterior angles.

< a and < e are corresponding angles.

Answer:

Step-by-step explanation:

13 + h = 21 for h = 9

1. Substitute 9 for the variable h.

Correct, because the question already giving the value that h = 9.

2. Substitute 21 for the variable h.

False, because in the question it states that h is 9, not 21.

3. Simplify by adding 13 and 21.

False, because they are in different sides.

4. Simplify by adding 13 and 9.

True, the question giving that h is 9. In the left sides, it's 13 + h, by adding 13 and 9, we will get the answer for the left side.

5. 21 = 21, so 9 is a solution to the equation.

False, because in the left side is 13 + h = 13 + 9 = 22.

6. 22 Not-equals 21, so 9 is not a solution to the equation.

True, see the explanation in 5.

Answer:

Substitute 9 for the variable h.

Simplify by adding 13 and 9.

22 Not-equals 21, so 9 is not a solution to the equation.

Answer:

5x-2y=-33

First.) -5x+10x= 5x

Second.) -5y+3y= -2y

Third.) -30+-3= -33

The equation of the line is the vertical line x = 3.

The gradient of the line between two points (x₁, y₁) and (x₂, y₂) is m = (y₂ - y₁)/(x₂ - x₁).

Since the line passes through the points (3,-3) and (3,8),  

So, substituting the values of the variables into the equation, we have

m = (y₂ - y₁)/(x₂ - x₁).

m = (8 - (-3))/(3 - 3).

m = (8 + 3)/0

m = 11/0

m = +∞

The equation of the line passing through the point (x₁, y₁) in point-slope form is given by

y - y₁ = m(x - x₁) where

So, substituting the values of the variables into the equation, we have

y - y₁ = m(x - x₁)

y - (-3) = +∞(x - 3)

y + 3 = +∞(x - 3)

y + 3/+∞ = (x - 3)

0 = x - 3

x = 3

So, the equation of the line is the vertical line x = 3.

Answer:

1

Step-by-step explanation:

4/9 and -5/9 are 1 apart. This is because one of the numbers is positive and the other is negative, you have to make the negative number positive and add the two positive numbers together. In this case, 4/9+5/9=9/9. 9/9 is equivalent to 1. So, 4/9 and -5/9 are 1 apart.

Hope the explanation and answer helps!
