Answer 1

Answer:

90deg

Step-by-step explanation:

If the angles are supplementary, that means mA + mB = 180*

we know that

mA = (2x + 8)deg

mB = (2x + 8)deg = mA

mA + mB = 180deg

mB + mB = 2mB = 180deg

mB = 90deg

Note, that we did not need to compute x even, because the angles were the same.

The function y= -0.2 + 0.5 represents the percent y (in decimal form) of battery power remaining x hours after you turn on a laptop computer.

A. Identify and intercept the x- intercept

B. Identify and intercept the y-intercept

Answers

Answer:

A

Step-by-step explanation:

intercept the x- intercept

Answer:

Step-by-step explain

x-intercept: 2.8 hours

y-intercept: 0.7 . . . . fraction of power remaining

Step-by-step explanation:

The equation is in slope-intercept form, so the y-intercept can be read directly: 0.7.

To find the x-intercept, set y=0 and solve for x:

0 = -0.25x +0.7

0.25x = 0.7 . . . . . add .25x

x = 2.8 . . . . . . . . . multiply by 4 (that is, the reciprocal of 0.25)

The x-intercept is 2.8; the y-intercept is 0.7.

Probability = 6/8 = 3/4

Answer: 75%

Step-by-step explanation:

Well there are 8 possibilities every time you spin. The chance is 6/8 that you land on a number less than 4, if you spin it once (since 6 out of the 8 possibilities are less than 4). So you just have to divide 6/8 which is 0.75. Multiply by 100 (move the decimal over 2 times to the right) to get the percentage which is 75%.

The relation is linear

Find the inverse.

( − 6 ,  − 3 ) ,   ( − 6 ,  − 1 ) ,   ( − 6 ,  5 ) ,   ( − 6 ,  8 )

Step-by-step explanation: IT'S NOT A OR D.. ig

1:    Recall that a function  from a set  to a set  is a relation that assigns to each element  in the set  exactly one element in the set . The set  is the domain (or set of inputs) of the function and the set  contains the range (or set of outputs).

The general characteristics of functions are:

A. Each element in A must be matched with an element in B.

B. Some elements in B may not be matched with any element in A.

C. Two or more elements in A may be matched with the same element in B.

D. An element in A (the domain) can not be matched with two different elements in B.

________________________________________________

Solving this problem we have:

1. The mapping diagram is represented in Figure 1. As you can see this is a function. Each element in A is matched with an element in B. All the elements in A are matched with the same element in B. So, this fulfills with the definition of function.

2. The mapping diagram is represented in Figure 2. This is not a function. Notice that an element in A (the domain) is matched with two different elements in B, that is, -8 is matched with -6 and 1.

2:    #1) This is a function.

#2) This is not a function.

(The mapping diagrams are not present to match to these.)

Explanation:

A function is a relation in which each element of the domain is matched to no more than one element of the range; in other words, no x gets mapped to more than 1 y.

In #1, no x is mapped to more than 1 y, so it is a function. However, in #2, -8 is mapped to both -6 and to 1; this x is used more than once, so this is not a function.

4:    Answer:

Option D is correct.

The relation {(-8, -6) (-5, 2) (-8, 1) (7, 3)} is not a function.

Step-by-step explanation:

Given the relation:  {(-8, -6) (-5, 2) (-8, 1) (7, 3)}

Domain is the set of all possible inputs of a relation i.e { -8, -5 , -8 , 7}

Range is the set of output values of a function i.e, {-6, 2 , 1 , 3}

The mapping as shown below in the figure:

A function is a relation in which every element of the domain is matched to not more than one element of the range.

In other words, we can say that ,no value of x gets mapped to more than 1 value of y.

Since, from the mapping you can see that the domain value -8  paired with -6 and 1;  as x is used more than once.

Therefore, this relation is not a function
