Answer:

(5) 84° and 96° ; (6) 40° and 50°

Step-by-step explanation:

5) <em>Supplementary angles are in the ratio 7 : 8</em>

So 7x + 8x = 180°

15x = 180

x = 180/15

x = 12

The angles are 7x = 7 * 12 = 84° ; 8x = 8 * 12 = 96°

6) <em>Complementary angles are in the ratio 4 : 5</em>

So 4x + 5x = 90°

9x = 90

x = 90/9

x = 10

The angles are 4x = 4 * 10 = 40° ; 5x = 5 * 10 = 50°

Function 1: y = 4x + 5
rosijanka [135]

Answer:

Option B is correct

Function 1, because the slope is 4 and the slope of function 2 is 2.

Step-by-step explanation:

Slope-intercept form:

The equation of line is given by:

y=mx+b

where, m is the slope and b is the y-intercept

As per the statement:

Function 1: y = 4x + 5

On comparing with [1] we have;

Slope of function 1  = 4

Function 2: The line passing through the points (1, 6) and (3, 10).

Using slope formula:

\text{Slope}= \frac{y_2-y_1}{x_2-x_1}

Substitute the given points we have;

\text{Slope}= \frac{10-6}{3-1}

⇒\text{Slope}= \frac{4}{2}

Simplify:

⇒\text{Slope}=2

⇒\text{Slope}= \frac{4}{2}

⇒ Slope of the function 2 is, 2

Since, function 1 is greater rate of change.( i.e 4 > 2)

Therefore,

Function 1  has the greater rate of change,  because the slope is 4 and the slope of function 2 is 2.

Which equation shows the inverse property of multiplication?
serious [3.7K]

Answer:

C

Step-by-step explanation:

The options are:

<em>A. 4 + (-4) = 0 </em>

<em>B. -8 + (-3) = -3 + (-8) </em>

<em>C. 2 </em>×<em> 1/2 = 1 </em>

<em>D. 8/5 + 0 = 8/5</em>

<em />

The inverse property of multiplication states that the product of a number and its inverse is one.

The inverse of 2 is 1/2. The multiplication of 2 × 1/2 = 1 , as the property states.
