Answer:

Neither

Step-by-step explanation:

To check whether an ordered pair (a,b)(a,b)left parenthesis, a, comma, b, right parenthesis is a solution of an equation, substitute these values into the equation and determine if the resulting equality is true or false.

To check whether (\blue{1},\pink{5})(1,5)left parenthesis, start color #6495ed, 1, end color #6495ed, comma, start color #ff00af, 5, end color #ff00af, right parenthesis is a solution of the equation, let's substitute \blue{x}=\blue{1}x=1start color #6495ed, x, end color #6495ed, equals, start color #6495ed, 1, end color #6495ed and \pink{y}=\pink{5}y=5start color #ff00af, y, end color #ff00af, equals, start color #ff00af, 5, end color #ff00af into the equation:

Neither of the ordered pairs is a solution of the equation.

Neither of the ordered pairs (1, 5) and (-1, 1) is a solution to the equation 7x - 2y = -5. The correct option is 4.

An ordered pair is a pair of numbers that represents a point in a coordinate system. It is written in the form (x, y), where 'x' is the horizontal value (abscissa) and 'y' is the vertical value (ordinate). The order of the numbers is essential, as switching their positions creates a different point.

equation: 7x - 2y = -5

For (x = 1, y = 5):

7(1) - 2(5) = 7 - 10 = -3 (Not equal to -5).

(x = -1, y = 1):

7(-1) - 2(1) = -7 - 2 = -9 (Not equal to -5).

Since neither ordered pair satisfies the equation 7x - 2y = -5, the correct answer is 4. neither.

Third answer option

{(1,2), (-2, 2), (-2, 4), (-4,4)}

Step-by-step explanation:

If the Domain is the set = { -4, -2, 1}, we need a relationship that shows pairs with first coordinates as described below:

(-4, ...) , (-2, ...) and (1, ...)

which we find in the third option shown:

{(1,2), (-2, 2), (-2, 4), (-4,4)}

Answer:

The answer is below

Step-by-step explanation:

A linear equation is in the form of y = mx + b, where y is a dependent variable (that is it depends on other variable), x is an independent variable (that is it does not depend on any variable), m is the slope (rate of change) and b is the value of y at x =0

Given that S is salary, n is number of working years. It is given by:

S = 90000 + 3500n

the slope = 3500

The equation means that Sarah's beginning salary is 90000 and the salary increases by 3500 each year

Choice B.   [-5, -4]

Choice D.  [1, 2]

===================================================

Explanation:

We're looking for portions when the graph goes downhill when we move from left to right.

The first portion is from x = -5 to x = -4. So we write [-5, -4] which represents [tex]-5 \le x \le -4[/tex]

The second portion is [1, 2] which goes downhill since the interval starts at x = 1 and stops at x = 2.

The portions are highlighted in the diagram below.

As you can see, we only care about the x values for any given interval. The y values don't matter as long as they decrease along the interval.

The two points that are 6 units from Point B (1, 3) and share the same y-coordinate are (-5, 3) and (7, 3).

To plot two points that are 6 units from Point B (1, 3) and share the same y-coordinate, we need to find the points that are located 6 units to the left and right of B while having the same y-coordinate of 3.

Point to the left of B: (1 - 6, 3) = (-5, 3)

Point to the right of B: (1 + 6, 3) = (7, 3)

So, the two points that satisfy the conditions are (-5, 3) and (7, 3).

Answer:

76, 70, 64, 58.

Step-by-step explanation:

By pattern I guess you mean common difference.

The first term is 76 so the second is 76-6 = 70, then we have 70-6 = 64 and so on.

The first 4 terms in an arithmetic sequence are 70, 64, 58, 52.

What is an arithmetic sequence?

An arithmetic sequence is a sequence where every two consecutive terms have the constant difference between them.

Here the first term = 76 and the common difference is = -6.

Therefor,

The 2nd term is = 70.

The 3rd term is = 64.

The 4th term is = 58.

The 5th term is = 52.

Double angle identity for sine:

sin(2x) = 2 sin(x) cos(x)

So rewrite the equation as

sin(2x) = cos(x)

2 sin(x) cos(x) = cos(x)

2 sin(x) cos(x) - cos(x) = 0

cos(x) (2 sin(x) - 1) = 0

There are two cases,

cos(x) = 0   or   2 sin(x) - 1 = 0

cos(x) = 0   or   sin(x) = 1/2

In the interval 0º ≤ x < 180º, we have cos(90º) = 0 and sin(30º) = sin(150º) = 1/2, so the possible values are 30º, 90º, or 150º.

A. P(E') = 1 - P(E)

B. P(E) - P(E') = 1

C. P(E) + P(E') = 1

D. P(E) = 1/P(E')

E. P(E) = 1 - P(E')

F. P(E)/P(E') = 1

G. P(E') = 1/P(E)

Answer:

Options A, C & E

Step-by-step explanation:

For the probability of an event E which is denoted by: P(E).

In complementary events, the complement of E is denoted by: P(E').

Now, the complement means the outcome that Event E does not occur.

This means that the sample space is 1.

Thus;

P(E) + P(E') = 1

It can be rewritten as;

P(E') = 1 - P(E)

It can also be written as;

P(E) = 1 - P(E')

The correct options are; A, C & E

Answer:

-0.663rad

Step-by-step explanation:

The angle in question is -38°

Using the conversion formula

πrad = 180°

xrad = -38°

Cross multiply

180 × x = -38π

x = -38π/180

x = -19π/90

x = -0.6632251158

Hence the radian measure of the angle to three decimal place is -0.663rad

Answer:

Yes, the correct answer is $6.50..

Step-by-step explanation:

Stacy earns $6.5 per hour.

Multiplication is the process of adding a number up to a given number.

Given that Stacy worked 6 hours each day for 6 days

The total number of hours Stacy worked is 6×6=36 hours

Therefore, Stacy earned $234 for 36 hours

$234 = 36 hours

$234/36 = 1 hour

$6.5 = 1 hour

Hence, Stacy earns $6.5 per hour.

Answer:

I got 106 calendars

Step-by-step explanation:

605 divided by 2.50 = 242. Next you have to add what you got to the initial cost. Then we get 847. Next you have to divide this by 8 and round up, and i got 106. I might be wrong XD

They need 110 calendars to reach $1200.

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

The initial cost to make the calendars is $605 for equipment with an additional materials cost of $2.50 per calendar.

We have to raise at least 1200$.

let x be the number of calendars.

Then, the inequality is,

8x - 2.5 x + 600 ≥ 1200

Solving we get,

5.5x≥ 600

x ≥ 109.09

x ≥ 110
